I found this mixer at Savers today. Complete with paddle, whisk and dough hook -- how did that happen? It runs smoothly and super quietly. It struck me as worth $29.99 so I snapped it up, and just in time, as another guy was ready to swoop in as I was examining it.

It's obviously a Hobart, but there is no information on the band saying so, or wattage information either (I presume it's the standard 250 watts).

Only on the base plate where the bowl locks in does it say "Hobart."

How can I tell its age? If a serial number would help, where would I find one?

There seems to be a tip broken off one upper corner of the paddle. What would that have been? The other corner is rounded, as are both corners on all paddles I'm familiar with.

Mine is from the 80s, and this is DEFINITELY

older. I would guess (but am guessing) 60s.

GOOD catch, Ralph. Still lots of life in it.

I did some Googling and it seems that it's not easy to pinpoint the vintage on a K45. This model was produced from 1962 to 1979, but the machines themselves don't have evident serial numbers. I did however, find volts (115) and watts (250) information on the bowl's interlocking plate on the base.

I was thinking my machine might be 60's but now I'm more inclined to say 70's.

Since it's a K45 and not a K45SS, it precedes the solid state control models, which per my research debuted in 1979. So, I've learned that my mom's almond Hobart K45SS is no older than 1979. The logo on mine is an earlier style and the mixing bowl has the earlier more tapered sides, and a pronounced lip around the edge.

Can anyone comment on solid state vs. non-solid state controls? The speed control on mine seems very precise with a brief and seemingly engineered hesitation before kicking up or bumping down to the next speed after the lever has been moved in either direction.

One thing is for certain. It's the smoothest, quietest running KA stand mixer I've ever heard, and likely a much better machine than the raspy chirpy Professional model I got my partner for Xmas three years ago.

Also, the broken piece on the paddle is some sort of tip section off that one corner, apparently less than 2" long. I've found illustrations and photos of the tip, and of paddles with the tip broken off. I'm debating on whether to try and smooth down the area of the break. I see no purpose for the tip section (but I guess Hobart did in the beginning) nor do I have any reason to think a missing tip will have any impact on performance.

Attention KitchenAid Mixer Owners!

rp2813's profile picture
My "new" K45 needs all five rubber feet (see pic below where there is no gap between pedestal and bench it's sitting on. The originals all look like quarter-sized under-done pancakes.

On line the per-foot price ranges from around $2 to $3.50, which struck me as ridiculous.

Then I saw a comment posted, I believe on Amazon, that advised "Do not buy these!" which went on to state that KitchenAid will replace them for free with no shipping charge either!

This morning I called KA parts, gave my model number and the representative went right into arranging to send them to me free of charge.

If anybody needs replacement feet, all it takes is a call to KA parts.

My K45 is from 2003. We had a nine month long grocery strike in California, I did not want to cross picket lines but I needed bread! I followed the French Bread 101 recipe in the K45 booklet and it came out great. Solid state control is quiet and seems to allow some variability in speed when you move it slowly from the first to the second notch.

The flat beater is white coated. Definitely not metallic appearing as the beater in your photo.

Excellent buy for $29. My model cost $169 from Amazon in 2003, but my net cost was $139 because they ran a special: for every $50 you spent on kitchen items, you earned a $10 gift card. So it was $169-$30 in gift cards back, or $139 net cost. Today, the same mixer costs $199 at Amazon, with no special deals. You can buy a new beater for it for about $10.

If you make cakes or cookies, consider one of the new flat beaters that scrapes the sides so you don't have to. You can always save the original beater for display, but the new scraper beaters work great.

Hey Rich, I don't mind zucchini bread at all.  That's about all I find that particular vegetable is good for.


I did get one of those after-market scraper type beater blades for the Pro HD machine and it does a good job.


I'm still trying to determine a timeline for the K45.  Like, when did they start putting the white coating on the flat beater and dough hook?  When did they do away with the flat lip on the bowl (which tends to scrape the paint off the pedestal if you're not careful when positioning it onto its base)?  When did they start giving it a three-prong plug?  On line research produces very little to help, and even KA's own on-line resource people state that Hobart didn't use serial numbers or other forms of identification that would help determine the age of their mixers.  All KA can provide is a huge spread, such as somewhere between 1962 and 1979 as I mentioned above. 


So far, all I know is that solid state controls were introduced in 1979, which is when "SS" was tagged onto the K45 model designation.  As the pictures show, my machine has the earlier bowl, uncoated beater and dough hook, and not shown is the standard two-prong plug.  The plug looks like it's from the 70's and may be the best indicator of my machine's approximate age, as I'm fairly certain the yellowed cord is original.


Today I perfomed a test on my K45 per Hobart's service instructions, which advises to hold the planetary with one hand and move the switch lever with the other.  With switch in the #1 position, it shouldn't be possible to stall the planetary (except by a very great effort), nor should it slow down noticeably.   It passed, but I did hear some clicking from inside the gear case and am wondering if there may be issues with big jobs such as kneading dough.  Since I don't bake bread from scratch I don't anticipate any trouble, but perhaps a gear could stand to be replaced at some point.

You might want to consider tricking it out with the three quart bowl, which should fit all K45 models but was introduced long after your machine was made. Great for single batches and smaller jobs, or when you need a second bowl in addition to the larger one. It nests inside the 4.5 quart bowl to save space. I have also bought them for friends and relatives who own KA tilt head mixers (it also fits the 5 qt Artisan series) and everyone has found them useful.

My KA is from the early 80's, and the plastic coating (guessing) on the beater is pealing really bad, so I've been thinking about getting a new beater, the one with the scraper looks pretty neat.


Post# 489831 , Reply# 10   1/18/2011 at 10:16 (3,597 days old) by PassatDoc (Orange County, California)        

There are several makes of after market scraper beaters. There are some with gaps in the silicone edge to allow nuts to pass without being crushed. I have the model pictured above. I use the scraper beater for making banana bread with walnut pieces, and I don't have problems with nuts being crushed. I don't use the scraper for very thick doughs like chocolate chip cookies because it could strain the motor (makes the beater harder to turn). I have the base K45 model with 250 W power. Quick bread batter is not as thick and then the scraper beater works fine. Also the mixer is great for making double batches of bread dough (7-8 cups of flour) with the dough hook.

The nice thing about your find is that new accessories are available to fit if something is broken or missing. You can keep the old beater for appearance, but you'll probably find that newer OEM or aftermarket accessories work better when you actually USE the thing.

What I find interesting is that the higher end bowl-lift type of KA mixers that can be bought today don't have the coating on the flat beater or the dough hook.  Our Pro HD came with un-coated ones, the dough hook being the later corkscrew type. 


I also don't get why the entry level K5 bowl-lift model has a spring-loaded attachment post, but models further up the line (like the Pro HD) don't use the spring.


I presume that the un-coated beater and dough hook that came with my K45 can be used, but yeah, if I come across some newer ones I'll probably grab them.  My mom's early K45SS made by Hobart has the coated type so now I think the clue to when my mixer was made could be in the logo.  I've checked on line and don't see any timeline for changes to the KA logo though.  Apparently plain old K45's were still being made when the logo was updated, so knowing when that change was made could get me a little closer to determining the age of my machine.

Kitchaid Flat Beaters

When KitchenAid first introduced the K45 in 1962. It was an upgrade to the previous K4 that had a 4 qt narrower bowl, and beater and a "screw-in" bowl. The flat beater had an "ear" to reach higher about 3/4" to catch more of what clings to the sides of the bowl. The early bowls had no rolled rim, (NSF approved)allowing commercial use. Not sure when nylon coating was begun, it is not mentioned in any Kitchen Aid product or feature time line. The early coated beaters still had the "ear." I believe taking the "ear" off was a part of new safety regulations, just like detachable cords and the hole to hang portable mixers on the wall being no longer available. KitchenAid now has it own silicone scraper beater that is retails for 29.99.

Russell, thanks for that good information.  I like the purpose of the "ear" on the flat beater and may pursue finding a replacement that has its "ear" intact.


Interesting that NSF approval hinged on the bowl rim.  I wonder why.


Although my mixer has a two-prong plug I think it's probably among the last made before the logo changed.  The reinforcement end of the plug looks much like the one on my Hobart K45SS.  I wonder if when the logo changed and/or when the K45SS debuted, if that is when the shape changed on the knob that secures attachments in the hub as well.

The K4 Mixers

rp2813's profile picture

After Russell's mention of the K4 series, I had to check Google to see what they look like.


No doubt about it, a late issue K4 (K4-C, I presume) is something I hope to find.  I think the handle on top makes perfect sense for tilting the head back, and the tail fin is right out of Flash Gordon.


I've seen pictures of K4's using their own original beater (like the 3B/4C types) as well as with the later flat beater, dough hook and whisk found on the K45 and other subsequent models, so other than the different and slightly smaller bowl design the K4's seem capable of doing anything the K45's can do.


The one pictured is missing its "hub cap" and has clearly had its cord replaced.  The tip of the tail fin is visible if you look closely.

appnut's profile picture

Not so.  Definitely not so.  I have a 4C.  I love it for the purposes I have used it for.  I am even blessed with the original glass bowl and companion beater.  I also have a metal bowl.  The 4C, from what I've been able to ascertain, was priced and designed to compete with Sunbeam, Waring, ... but still be a KitchenAid.  i also have the recipe book/users manual for it.  It specifically states it's not intended to be used to make yeast bread dough and similar dense item.  It will tackle a dense batter bread/sweet bread and can also tackle heavy dough like chocolate chip cookie dough (see arhives of Kelly finding this unit and using it when he visited with his grandduaughters in Kansas August, 2009.  And you are really not supposed to use any other device other than the multipurpose whip/beater that it came with.  I can see where it cannot deal with yeast bread dough and kneating like a K45 with the dough hook.  But I love it, I'd never had a stand mixer before, only a KA hand mixer that finally wore out after 20 years.  I still have my Sunbeam food processor which makes excellent bread dough very rapidly and I use recipes where I don't have to proof the yeast (and take a chance of it either dying or being killed with accidentally too hot a water).  I discovered by accident how superior a bread product is the result of bread flour vs. using all-purpose flour.  I now use only the bread flour when I make bread.

So Bob, are you saying that the K4 and 4C are the same mechanically but with different housings, pedestals and controls?


I'm not a bread baker so it's not important to me that a K4 is or isn't able to knead dough.  I just like its practicality and looks.

Ralph, my 4C does not look like your above.  I've only known my to be referred to as a 4C, not a K4C.  It doesn't have as large motor as yours does.  It's a lighter duty, more of a medium duty.  Yours comes with a dough hook so you can do bread dough.  Mine doesn't .  That doesn't bother me at all.  Since I have an option for making dough, I am very pleased with what my mixer can do for me.  I don't think the K4C is the same as the K4. there's a little portion of my 1982 Sunbeam LeChef food processor.  that's what I use to make bread dough in.

Here it is with the original glass bowl which came with these models.  They were made form like 1961 until 1977.   Not the difference in the mxing attachment.  It's an all-purpose, universal type of function.  It's very similar to the Combi-bowl, which was a 3 quart bowl for lift-bowl design models which had its own beater and looks similar--so what's old is new again.

Thanks Bob.  My research indicates that the K4's date back to the 1940's and were originally 3-speed machines.  I think Hobart probably dropped the K4 in 1962 when the K45's were introduced.   I think by that time the K4's were up to 10 speeds or close to it, so that's why I'd like a later one, probably a K4-C.


So from what you've stated about the 4-C, just about any 4-C is likely to be newer than any K4, which is not what I would have expected. Your 4-C is very nice looking in that silver color.


Strange how the K4's had that weird way of attaching the bowl to the pedestal.  It seems no other model before or since had that same arrangement.

Hi Linda,

There doesn't seem to be any sure way to determine a K45's age.  What does the logo look like on yours and what does the knob for the attachment hub look like?  Pictures of those may help somewhat.

Others know KitchenAid better than I do. As Ralph said, others might come up with a date with more photos of the mixer.

But I can say I'd assume it's no newer than 1980-something because the plate says "Hobart", which sold KitchenAid in the 1980s to Whirlpool.

Look under the mixer inside the neck. There may be a white rectangular piece of paper sticker with purplish numbers on it. It looks like an unimportant manufacturing sticker.

clues to age of Kitchenaid

Maybe the UL or CSA ratings organizations can state when standard voltage changed from 115 volts to 120 volts per their small appliance rating plates to at least narrow the age range.

I first saw the 4C on the French Chef in the 60s, when Julia wanted to be able to show what was happening in the glass bowl.


I have used mine next to the K45SS for making two pound cakes at a time. I used to bake 8 cakes in Bundt pans at a time. They went into the ovens 20 minutes apart. After the last cakes were put to baking, I got all of the prep stuff started washing in the KDS18. By the time I got the counters cleaned up, it was time to take the first two out of the oven and that process continued every 20 minutes until they were all done. While the finished cakes look the same, the 4c produced a batter that is much thinner than the thicker batter of the 45. I don't know why. I bought the metal bowl & white plastic pouring shield for the 4C so, except for a different beater, they are outfitted the same. It must be the different beater that makes the difference.


I had some trouble with the speed control of my original 45. After high speed mixing, like to get the eggs incorporated thoroughly, it did not want to slow down completely when shifted to the lowest setting to fold in the flour. I had it made into a 45SS by Hobart.

How old is your mixer?

It has to have been made prior to 1974 because Hobart Manufacturing Co. became Hobart Corporation in 1974. The possibility exists that there were left over bowl clamps like yours that continued on the assembly line but they probably changed over to say Hobart Corp at least by 1975.

I still use my 3B/4C mixer that was from the 40's and it still works like a charm. Turns out the silkiest, smoothest cakes even from store bought mixes. Just the right size and lighter than my K45's.

The K

Came out about 37 and was a 3 qt Then the K4 These replaced the much heavier bulkier model G which is the same as a Hobart N50 ...the 3 A and B were made for lighter duty to compete with Sunbeam, The 3B was replaced by the 3C in 1950 then the 4C whick had a larger bowl, The K4 was built until the K45 came out Its a heavier duty machine than the 4C,, The K and K4 both have tinned steel bowls, but yes The K4 is basically a K45

Excellent Hans,

I didn't know the timeline of their product evolution. My high school buds mom had a K5a from about 1976, and the nylon drive gear in the head stripped after onyly a year or 2 of use. The repiar center fixed it no charge though. Do you kniow when they stopped using all metal gearing? We go to an ice cream parlor where they use liquid nitrogen, and they have the commercial ones. You can tell they must have all metal gears as the sound is totally different.

Anyone knows if there's a serial number stamped somewhere on these? My 4C says Hobart MFG which I assume makes it older than 1975? There's a hand written note under the base, is that a date code?

Fix it help

Trying to get this lovely back up and running. Think the head needs adjustment and any guides to attachments that might fit? The attachment seems to need a slightly larger opening hang than some of the paddles sent with it. Also seems the head is tilted a bit too far down. Worth fixing I think. Motor is fine just not fitting the bowl and again think head is too far forward.

Neither of those attachments appear to be the correct size for your mixer.   The one with the white coating looks like it's for a larger mixing bowl and the burnished one looks like it belongs on a smaller model of mixer.


There are owner's and service manuals available to download for a fee (see link).  You should also consider a later style mixing bowl that has a rolled rim.  My K45 had the same scratches on the stand from the edge of bowl rim.

RE: Look Under

Heya Louvac, just got my mom's old mixer and found these forums and your question. Looked under the mixer and there's a sticker. It is in purple and white and says , 9577.

I'm guessing it was made in 1977.

What say you?

Also wanting to date my K45

I've had a Hobart-made K45 for about three years and have always been curious to figure out just how old it is. I've always estimated it to be from the mid-70s, just based on the color (pale yellow, possibly "Harvest Gold") and condition, although after reading the messages above, I suspect it may be a little older and certainly made before the company changed its name to Hobart Corp.

The plate where the bowl is mounted reads "KITCHENAID DIVISION THE HOBART MFG. CO. TROY, OHIO." It specifies 115 Volts and has the UL seal but not the CSA seal. It also has a line stamped along the lower edge that I have not seen on other plates, reading "CAUTION: UNPLUG BEFORE INSERTING OR REMOVING PAR" (see photo) which is also printed on the band around the motor housing (except the last word is complete).

The sticker inside the base reads "17379" which, if it is a date code of some sort, I cannot easily decipher. (Perhaps "73" is the year?) The bowl has a rolled edge (no significant nicks on the pedestal) and the power cord has two prongs.

I just bought a new Artisan Series mixer, which is scheduled for delivery later on today. I am looking forward to comparing the two machines.

Any guess as to when this machine may have been made? It runs well and passes the try-to-hold-the-beater test. The only reason I bought the new one was so that it would match all the other appliances in my kitchen, and the price was right.

David, your mixer appears to be among the last ones made before the the SS designation.  I would guess it's from the late '70s.  The round knobs for the speed and lock levers provide another clue.  I think it wasn't long after production began on the SS models that the knobs were changed to the style still in use by KA today (compared to your new Artisan).


The black brush adjusting screws on the side of your mixer also stem from a design change that (by my estimation) was made around the time the SS models were launched.  The attachment hub cover on your machine appears from the side view to be the later type with the KA logo on it, which likely means the original plain cover was lost at some point.


I don't know what to make of the sticker on yours.  Perhaps if you disregard the 1, then July 3, 1979 could be the date of manufacture.  I haven't been able to determine when KA switched from the font style on my mixer in the OP to the style found on yours, but I think it was well before 1979. 


Lastly, the "caution" verbiage reeks of advisories and idiot-proofing that began appearing in the late '70s on all sorts of household appliances regardless of manufacturer.

Thank you, Sannazay, for your assessment. After posting my previous message and thinking more about that sticker, I agree with you that my machine is a 1979 vintage. What threw me off track initially were other messages I had seen that said Hobart had dropped "Manufacturing" from their name in 1974. Either that was incorrect information or my machine was constructed from parts that were remaining in inventory five years after the name change, specifically the locking plate (AKA screw cap kit).

Reinterpreting that sticker without considering the name change leads me to believe that my K45 was made on day 173, or June 22, of 1979. Thus it could indeed have been one of the last of the K45 models to be assembled. I tried to look up the date on which the assembly line switched over to building the K45SS model but couldn't come up with anything.

Incidentally, you were correct about the attachment hub cap having been replaced. It was missing when I acquired the machine from the son of the original owner and I didn't like looking at the gaping hole in the housing. Perhaps I should have bought an original, unadorned cap from someone on eBay, but the one with the KA logo looks very contemporary.

My new Artisan 5 qt. (KSM150OB) is nice and all, but I'm really cheesed off that Whirlpool decided the spring-and-washer assembly on the "agitator" shaft was superfluous and eliminated it sometime around 2016. Without that spring, the flat beater/dough hook/whisk attachment doesn't snap on with authority, thus forcing the user to look to make sure the attachment really is engaged. The original Hobart design showed great attention to detail, the subtlety of which seems to escape the Whirlpool engineers.

You can't buy those parts from Whirlpool parts retailers anymore, so I had to order them individually from other sources so I could "upgrade" my machine to original specs. I couldn't order just one spring and one washer, so I ordered the smallest quantity of each that I could order. I may end up combining the surplus pieces as kits and selling them on eBay for anyone who wants to make their machine whole again. Pulling that planetary assembly is so simple that anyone with a modicum of mechanical ability would be able to install the kit easily.

Over the next week or so I will be cleaning out and repacking the gear grease on my K45 -- using genuine Benalene 930-2 grease, of course. One has to be very careful if using ordinary food-grade grease, as the temperature profile might be completely different.

I haven't decided yet whether to keep the K45 or to sell it to someone who can give it a good home. It is in really great shape but, to be truthful, I really don't have the space to keep two KitchenAid mixers. If I do keep it, however, I might upgrade it to electronic motor control. (The last I knew, America's Test Kitchen still rated the 4.5 qt. KitchenAid mixers as their "Best Buy" in consumer stand mixers.)

Oops, I meant "Ralph," not "Sannazay."

David, I think you've figured it out.  I hadn't thought of the 173 referring to day of the year, but that's likely correct.  There is no sticker inside the base of my K45, so it will remain a mystery as to its age until more information shows up on line.


I think the original attachment hub covers were easily lost.  They were simple round flat plates with teeth around the edge that snapped into place and were pried out.  The new types are held in place by the tightening knob on the side of the hub, and just due to their size are a lot easier to keep track of.  I keep a vintage knife sharpening attachment in place on my machine and after checking in all of the logical spots, can't find the plain hub cover plate for it now.  I know it can't have gone far, and hope it will show up.


You're right about the "missing" planetary spring, but I thought that only the larger bowl-lift models had no spring.  I bought my sister a refurbished 6-quart model from KA on line and immediately noticed the missing spring.  I called and was told that the bigger models don't use a spring.  If your Artisan is a tilt-head type, this is the first I've heard of KA doing away with springs on that design too.  I agree that the spring helps to confirm that the paddle/whip/hook has been correctly installed, and it's good to know that a retrofit is possible.


I loaned Robert (our webmaster) my K5/K45 service manual and he has scanned and posted it in the library to be downloaded for a small fee.  That may help you with your rebuild/refurbishing, but I suggest you hang onto the K45 until you're sure you like the Artisan. 


I wouldn't bother with upgrading the speed control unless it's presenting problems, and besides, a new SS control wouldn't have the vintage round knob on the sliding lever like the original does, resulting in a mismatch with the locking lever.

Logo As Indicator

rp2813's profile picture

Chalk it up to too much time on my hands during the current situation, but it occurred to me that in trying to figure out when the KA logo changed to its current iteration, I shouldn't limit myself to researching mixers.  Duh.


So I did an online search of dishwasher pictures and magazine ads, etc.  It appears that the last dishwasher KA produced with the same logo as seen on my mixer in the OP was the 15 series, which was introduced in the mid '60s.  I also found magazine ads from 1966 that showed a 15 series dishwasher but the copy of the ad included the later logo, so the transition appears to have taken place around then.


Based on this, I'd say my K45 can't be any later than the mid '60s unless they had lots of tilt head bands with the older style logo to be used up.  I can't say for sure when that logo began appearing.  I saw ads from 1960 with it, I think for a series 14 dishwasher, so I suppose my mixer could be at least that old.

New 1.3 HP Pro model or stick with my 45 S Kitchen Aid Mixer

I;m trying to figure out if the new 1.3 hp motor will be better or same as my 45S that was my Mom's I don't know how hold it is exactly, but I know it was purchased around 1972 (+/- 2 years). It's harvest gold. The purple number on the sticker is 22979, whatever that might mean. It still runs great, but the capacity is small for bread, pasta and other dough. Thanks in advance for any help, thoughts or opinions.

I think durability and the noise factor are the big negatives with newer KA mixers, but if you need more capacity, yes, you'll need a new mixer.  I would suggest you try to stick with a tilt-head type if there's one on the market that's large enough for your needs.  I found the bowl-lift Professional HD that we had was annoying to use.


Per research I posted above, I think your mom's K45 SS isn't likely older than 1979.

New 1.3 HP Pro model or stick with my 45 S Kitchen Aid Mixer

I know for a fact it was bought way before 1979. I was there when she got it. I just can't remember 1972 or 73 (related to when we moved & the new all harvest gold kitchen/ I was about 14). Thanks!
