Got a little problem with the 1256 that I have the Sickle-Mo mounted on. Not REAL serious but danged aggravating.


The idler for engaging the PTO and the idler that keeps pressure on the drive belts are on the same shaft.


When I after I engage the PTO and then disengage it, it pulls the idler for the drive belts back as well and of course, the tractor won't move.  The first time that happened I thought I had some major problems.


Any way, I can shutdown the engine, push the drive belt idler back in, and all is well until the next time that I have to disengage the PTO


I've sprayed it liberally with PBblaster, but that hasn't seemed to help.  At least not yet.


Anyone with any other suggestions?

There's Nylon bushings on the shaft.  Possibly one worn out and broke in half causing the resistance.

Or the shaft could have just rusted from sitting out in the elements......

:ditto:   Yeah, it is either something giving resistance on the shaft or possibly the tensioner spring is worn out and you could use a tighter spring on it to help pull the pulley tighter on the drive belt.  Also, depending on how much the pulley moves out after you disengage the PTO, could the drive belts be stretched out and too loose with age?  Maybe some new belts will keep things tighter as well.  Hard to say without being there what exactly the problem is though.
