Well, I hate to sound like a broken record, lol, but YES I have both the operators manual and the repair manual for the bailer. I can take a pipe wrench onto the pto shaft and easily turn the bailer. Ive had it hooked and running off my 48 H Farmall several times before I got the 990 D Brown.
The U joints on the bailer are fine.
I was standing behind the tractor/bailer, and at an angle to see both easily. Boy was driving it. I was trying to bale long stem haygrazer that was around 3 to 4ft tall. I saw the smoke. From where I stood it looked like it was coming from the rear. Boy said it came up from all around him. The tractor wouldn't start, and was HARD to shift. I couldn't shift the PTO out of gear.
A day later I tried to run the tractor and shift the PTO in gear. No Go. I stopped the tractor and could THEN shift it into geat. Then I started the tractor and it ran fine for a couple minutes. I shut it off.
