chipwitch 73 #1 Posted June 22, 2014 Used my tiller for the first serious attempt since buying the tractor. The manual explains how to adjust the PTO clutch but they are rather miserly with words. I just don't know if it needs adjusting or not as I'm not sure how the tiller should perform. When tilling, if the tines encounter an uncooperative root, something has to give. What? PTO slip? Tiller belt slip? Tines break? Tractor flips? I'm guessing the PTO clutch, but today, it seemed like it slipped way too easy. I had the tiller set to as deep as possible and had to ride the drive clutch in low, first gear to keep from slipping the PTO. The tiller would try to climb a bit if I went too fast (not riding the clutch in low, first), but the clutch would usually slip before the tiller crawled back up to the surface. Admittedly, I was tilling under a tree, but I did so radially, backing the tiller to within about 5 feet of the trunk before commencing. No major roots were encountered and the soil is typical Florida packed sand with turf. Am I expecting too much from my rig? Share this post Link to post Share on other sites
can whlvr 994 #2 Posted June 23, 2014 my tiller is unstoppable,it will hit a root and lunge the tractor forward before the pto slips,you might have to adjust the trunnion a bit more,away from the seat tightens the pto,if that doesn't work look at the plates and make sure they arnt worn or oily Share this post Link to post Share on other sites

MalMac 1,332 #4 Posted June 23, 2014 Also, if it has been slipping, look for glazing on the pad and on your pulley PTO surface that comes in contact with the disk. If it's glazed the glazing will need to be removed of roughed up. Share this post Link to post Share on other sites
chipwitch 73 #5 Posted June 24, 2014 Malmac, thanks. Checked it this morning. Already set as tight as it would go, so I disassembled the clutch. Past the rivets Deep grooves in the pressure plate(?). Found a replacement lining on ebay for $48. I refuse to spend that much. I'm thinking I'll need to turn down the plate and find a thicker lining to compensate. Anyone know how much turning down the bell will take? Share this post Link to post Share on other sites
Save Old Iron 1,571 #6 Posted June 24, 2014 I have been meaning to try one of these http://www.ebay.com/itm/310638043144?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 I would try a light cut on the lathe to see if the new lining and light cut get you back in operation.

SousaKerry 503 #7 Posted June 24, 2014 I would put up a want add on here for a replacement bell. If memory serves there isn't a lot of meat towards the outer edge of the plate so turning it down will weaken it substantially. You should be able to pick up a used one fairly cheaply.
