Zetor 5211 Pto

[rtennant]

I'm new to this and still trying to figure it out, I have zetor 5211 and pto lever tries to kick out when bush hogging. No wear anywhere i found. Extended detent spring with nut under spring, about 3/16, but that not helped. I pulled off the top of trans and everything looked good there. Whattayathink?
Thanks for any help

Is the shift fork solidly attached to the sliding rod ?
Its attached to the 540/1000rpm selection right behind the clutch, and also to the independent/ground speed/oil pump selection muff in the rear end.

probably a bolt is getting loose, allowing the fork to move while the shift rod is held by the detent.

Hi, The540/1000 rpm selector is in the middle between the 2 levers. I guess i have to pull off the top cover on the trans and check again. I got book on Zetor, which shows nothing of the electrical wiring, and give no description of any parts. It is terrible book for $63.00. High school drafting class taught me to do better than that.
Anyway you say the fork on the sliding rod for the pto might be loose? Meaning if the gear is not in place where it goes it will try to pull on out of gear? If so i could pull lever on past the detent and it would stay in place?
Would you have a drawing of this thing better than what I have, which doesn't show any detail?
I tear it back down and take another look.
Thanks
