Have a d330 Hobart mixer was wondering if I can upgrade to a 40 qt bowl and accessories for this mixer, and if is possible, and if will do the job.been tell that I can do this upgrade but not sure thank you will wait for the answer.

One would assume that if you get a 40 qt. bowl. you will most likely increase your batch size, correct, i would make do with what you have, that mixer was designed for a 30 qt. bowl, not a 40, hence the d 340 model, but the choice is yours. i would stay with what you have, monomoy

Hi Monomoy,
looks like you are familiar with all those Hobart mixers. Hope you can help me too.
So I have a HL600. Got it from a school. Was working prior to remove from the school facility.
A month later plugged it in. Worked for like 20 min and stopped.
Bowl still goes up and down but there is no lights on the display.
And mixer wont start at all. Called Hobart. They sent out a tech. He checked the mixer and said all is good with it just the control panel board is bad. Ok So I got another board. Same thing. Mixer worked like 20 min and stopped. All the same sypthoms. Now since the tech said its the board thought OK. Let's put another board on it. And same thing happened again. Mixer stopped, lights disapeared.
Now we have 3 mixers and 3 bad boards I guess.
But I don't think the board is the problem anymore. What's the chance that working machine when I take out the board and put it on another unit it won't work.
The problem must be something else.
Please let me know if you have any ideas how to get them back working.

Much appreciated.
Regards Stoyan

The 330 and 340 are virtually the same mixer. The 340 has a taller bowl. They make a bowl extender rind for a 30 quart bowl to extend it to a 40 however keep in mind if your doing a heavy or dry dough mix I would not recommend you do this as your machine is designed for certain uses. The extender rings really are not for allowing for a larger batch but more to keep lighter high speed mixes in the bowl instead all over you the machine and surrounding area.
