Anyone familiar with hobart 20 qt mixers?
Is anyone here familiar with older hobart mixers? I was recently given one and have used it for the first time this morning. As a test, I made a double batch of sourdough which is rather small for a 20 qt mixer but too large for my 300W K45 stand mixer. The 20 qt mixer kneaded the dough in far less time than my K45... it passed the a windowpane test after 8 min of kneading while my K45 usually takes 13-15 min. I did observe a few noises while mixing that I captured on a video . While not in the video, I also observed the clutch to slip once and the rotation speed increased momentarily. It is an old mixer that has sat idle for quite a few years. Is there anything I can do (grease/oil) to refresh it a little? I have the user/operator manual with the exploded parts list from hobart but I've never disassembled and re-greased one myself.
