those electric clutches are problematic and kubota got away from them, easy to replace painful to buy, if it does not engage after cutting and stopping briefly, get a new clutch,
btw service your hyrastatic, the Kubota dealer here said it was sealed and not servicable, BUNK, do a search and ignore what you find except for where things are geograpically on the machine, the hydrastatic has a screen that gets clogged, if left too long will ruin it, after I cleaned my screen it worked fine, we are just praying the dealers poor advice did not make us wait too long to perform this essential task, the proper fluid is 20w50 motor oil not hydraulic like the dealer says, the proper level is 10mm below the oil fill hole, running out is over full, i did notice that running out while jacked up ends up being just a touch lower than the 10mm once leveled up, before I cleaned the filter it whined and would not go up a hill, even the whine is gone now, trick to this whole process was to have a flat steel band about 1 inch or so wide (packing strap steel is great) handy to hold the spring check ball and filter up while I put the plate on and then yank band out, prior to this operation use very little of the proper high temp silicone, add sealer at exit point of the band and tighten it up, oh yea the filter o rings and check ball want to fall out so the band is to hold them up, put a very small amount of sticky grease on the orings to hold them in place, after that you MUST run the hydrastatic thru the gears so to speak, I did this for about 15 mins and was successful at getting the air out and correcting a non functioning hydrastaic on my TG1860 diesel. I am only disappointed that I see so many posts from days gone by where others got poor advice, make me want to yell this message from a mountain top, I have to say many thanks to Dennis at the Georgia Kubota factory for preventing me from following irresponsible advice from the dealer here in Maryland. :thumbsup: You will not find directions on this process in the service manual or owners manual.
