I just never run out of new things to learn. The clutch slipped a few times in my 2-135 last fall when I was chopping. Not actually in the field, but when I pulled out in the road pulling the chopper and loaded wagon and tried to get going in road gear. I started spring work with it and it would break loose a time or two when it was pulling, usually in the mornings. Monday, it started acting up pretty bad. I figured it had oil on it, but after I'd let it burn off and it started pulling alright again, as soon as I'd shift the O/U up, it would let loose again.
About 2 o'clock, it dawned on me, there should be a drain hole in the bottom of the bell housing with a cotter pin in it to keep it clean. I stopped, looked up under it and sure enough, there was. I touched it and hot oil dripped out. I took a pair of pliers out of the toolbox and wiggled it. Oil started running out in a stream. I checked it again after a few rounds to be sure it hadn't plugged again. After an hour or so, it had slung all the oil off the flywheel and burned it off the clutch and it acting perfectly normal. That hole must have been plugged for a long time until the oil got high enough for the ring gear to start slinging it.
