Hobart A-200 F, Serial Number: 1688947, Spec 16865
The first gear can be easily stopped by hand which to me indicates the perhaps a shear pin is broken. I have also heard that the diving key may be the culprit. I will be opening it up and having a look but would appreciate any insight based on the serial number and spec for my particular machine.

There is a lever that is riveted to the shaft that controls the movement of the diving key. It may be broken. Email me and let me know what you found. [email protected]

That's a bargain if it works. Apparently the date is hidden in the last three digits of the serial number, so February 1998 seems likely. The only sure way is to contact Hobart themselves. They have a great service department. I have used many Hobart mixers in my catering career.
I found this;
As the previous poster mentions, you can't decipher Hobart serial or ML numbers. I have about 30 pieces of Hobart equipment ranging from mixers to slicers to reach-ins to dishwashers and I couldn't make heads or tails of the numbers. Finally, I got hold of someone at Hobart who I emailed all the model numbers, serial numbers and ML numbers to and they emailed me back the month and year of manufacture. Even after I got the information, I still couldn't figure out where in the serial and ML numbers the manufacture dates were buried.
Ed, if you continue to do it yourself, the end result will be tossing good money out. Have a professional check the system and save the unit from permanent damage. Chipping parts of a gear off means a serious resistance force or action has occurred. One force is slowing down as the other is speeding up. Gear alignment can be moved off center, or a sudden application (sudden stop or start) can damage the least resistant parts. For example, when a hook turns within the mixing chamber and the resistance of the content is too great on the turning shaft and gears, which ever part is weakest will break. Complicated I guess.
I would say without looking at it a key is sheared or gear teeth are worn on the gear.usually its a sheared key,however if the mixer is older they use a dive key assembly which you would have to replace the shaft.I'm a hobart tech and repair these mixers often,any ? let me know.What is the ml # on the data plate?
Hi All. Since the original poster has not responded to my request for ML and spec. #'s, I'll offer a solution based on a spec.# 3943 for anyone with the same problem. This is an older model A200 with a solid aluminum gearshift lever.
Stop using the mixer!!!
The slow speed gear (1st. gear) is engaged by a "diving key". Over time this key can wear to the point of failure, or break entirely and will no longer engage. This failure only affects the first gear, allowing the second and third gears to function properly. If you can stop the mixer attachment by hand while in 1st. gear, then you have the above problem. The unit must be serviced. If the key has been sheared there is the potential for a broken piece of this key to get into the trans. grease and cause further damage to the mixer. For a Hobart Tech., this is relatively easy to repair as a minimum number of parts need to be removed in order to expose the diving key.
Call your local Hobart office to schedule a repair. If you've never done any repairs on this model, do not tackle this project by yourself. I you have some experience with this model goto the hobartservice.com website, register for free and then download the parts list. Ensure that you have the list for the 3493 spec.
Good luck!

If the mixers are older the dive key shaft,spring or key are broken,if they are newer the key is sheared.Also check the nuts near the beater shaft and make sure there not too tight.
There is a two letter code that translates to the month and year. You would need to call Hobart to translate. 1-937-332-3000
There are hints to the age, first two digit of the S/N is the factory. "11" are the older ones, spec vs ml on plate, type of power switch, bowl gaurd....
goto this site http://www.hobartcorp.com/default.aspx. you will find a parts list/view. before ordering any parts i would call your local hobart branch because the part numbers have changed.make sure you have the ml number or spec number found on the data plate before hand so youll get the right part numbers.any questions let me know,i repair alot of these mixers im a hobart service tech.
