ss74nova Posted May 11, 2014 Posted May 11, 2014 Simplicity 725 mid pto adjustment for mower deck. Having a hard time adjusting. I can get the tension on the belt ok by sliding the ajuster collar & spring to about 1" gap, but the lever won't lock keeps flipping back to disengage. Any ideas? Thanks, Tim
ss74nova Posted May 11, 2014 Author Posted May 11, 2014 The rod seems kind of worn & the hole in the bracket that the rod slides through too. Tried to bend the rod seemed a little better but not enough. Maybe I'll try bending the rod in a different spot.
rokon2813 Posted May 11, 2014 Posted May 11, 2014 You have to get the adjustment set so that with it engaged, the handle goes down a bit past center, so the spring tension holds it engaged. It kinda locks itself in. On some I have had to bend the rod, so that it dips a little, but it should be straight I think.
ss74nova Posted May 15, 2014 Author Posted May 15, 2014 Thanks Dan. I straightened the rod & it seemed a lot better. The lever with the knob seems to go past center. I have about an inch between the locking collar & bracket for the spring tension. I had it set & thought it was good, until I started the tractor & the vibrations made it slowly flip forward & disengage. I slowly tightened the 2 nuts on the pivot lever to tighten the lever up & seems to hold now. If I tighten the nuts all the way I can't move the lever. I'll see how long it holds when I try to mow with it.
ss74nova Posted May 29, 2014 Author Posted May 29, 2014 Update: Tried mowing with it & on the first pass halfway around the yard after 2 right turns it was barely blowing grass out the deck. The lever flipped forward some again. Tried adjusting it & bending the rod different ways again. Kept flipping forward when I would run the tractor from the vibrations. Tried adjusting again & noticed the lever would hit on the steering arm when engaged. That explains after a right turn it would hit & disengage the pto. Don't know why I didn't see that before.:I Rapped the steering arm down with a hammer. Works great now. It adjusted just like Dan said. Thanks Dan.
