I have a 60 qt. Hobart Mixer and it works but I can literally grab the dough hook and stop it with my hands, when in first gear. Does anyone know what the problem could be?

The most likely cause is a faulty gear/gears or a faulty shift mechanism.

If you do not have experience fixing large mixers, I suggest calling in a qualified service technician.

A 20 qt "E" dough arm is S-23467. A 12 qt is S-62886.
A 20 qt "S" sweet dough beater is R-8022.

if the mixer is a 3-phase unit, that mixer has no reverse speeds, all gears should turncounter-clockwise when mixer is on ,if a 3-phase unit try switching any 2 of the incomingline to to change direction

Hi. You should consider a few things. They type of hook you use, can greatly affect your end result. If you're making a yeasted dough with a high protein percentage 12-13%, you should be using an "ED" hook, this is a spiral hook that has a sharp turn at the tip. You can find them on eBay for a competitive price. I believe that Hobart also sells them, but for a higher price. They are very good for mixing pizza type doughs, they also do an excellent job kneading the dough.

Have you checked the flour for lumps before it goes into the mixer? Have you tried sifting the flour?
Are you adding all the liquid and flour at once? If so try adding flour in stages to all the liquid. If you find that this solution helps you, please rate it. Good luck! ricardok45

It sounds like you sheared a key in the transmission.Does any gears work?were you using 1st gear for dough?

In what speed is it slipping?You only use 1st speed for dough,right?Can you put it in gear and stop the hook from moving with your hand?Let me know.

take top front cover off see if motor is spinning when turned on? hum can come when motor is running or transmision jammed or motor has issue like capsitor bad or start switch inside motor bad.

The bowl holds 20 quarts--are you overloading the mix?This mixer is not made for medium/heavy pizza dough.Depending on the pounds of dough,water and other ingredients will affect the mixer in some way.

Does the mixer work in any other speeds?Are you mixing pizza dough and in what speed?I service these mixers alot--i work for hobart.It sounds to me like you have a sheared key on one of the shafts.The mixer doesnt have a clutch.

the motor protection board is doing its job.you should only use 1st speed to mix pizza dough.im a hobart technician and service these mixers all the time.let me know
