PTO? Issue
 

This post is in regards to the one I put up about belts---

AND I'm sure it's been beat to death--

but I'm not sure if my PTO is slipping (at least it SHOULDN'T be).

While mowing in heavy grass the engine did not bog but the deck slowed. I suspected the belt because it's a sunbelt and I've never heard of them. I did some playing today and with the PTO engaged, I manually turn the blades (spark plug wire disconnected!) by hand, hold the generator, and I can see the PTO slipping some.

I'm confused, because a 30+ YR IH mechanic rebuilt the PTO at the beginning of the season because a PO had gernaded it, and used new parts.

I hope I don't have to take the PTO off again. :bash2:

What might be going on here?

I think I'd check to make sure its getting proper voltage. The less volts the coil gets the weaker the magnet is.
I'd also check the air gap on it.

Wait..what? Was this posted in the wrong spot? I'm talking about a PTO issue...

My bad. I thought it had an electric PTO. If it were, There's a coil of wire in the pto which when energized turns into a magnet causing the armature to engage the rotor, which in turn spins your belt pulley.

He didn't specify a model of tractor nor if the PTO was mechanical or electrical. Confusion understood.

My mistake-

It's a mechanical PTO on a 147.

I took the PTO off after realizing that one of the throw out levers was loose in the engaged position. I believe that is causing my slip. Now I just have to work on tightening it up again.
