PTO and/or tiller issue

[andythomasday]

Hey all,

I have a l2650 4x4 and I just put a new 4' king kutter tiller on it today. Everything works fine until I raise the tiller while it's running. I've done this before on other tractors with no problems. When I do it it's really jerky. Lowering the tiller doesn't cause any problems. I've tried fiddling with the hydraulics valve beneath te seat and it hasn't changed the jerkiness. I also notice that when I put the hydraulics lever all the way down while tilling I can move it almost halfway up with no upward movement of the tiller. The upper half of the lever distance moves the tiller at a steady, jerky rate. I don't notice the jerkiness with a blade but there isn't a pto running. Maybe the pto shaft from the tiller to pto isn't lubed well enough. Although I thought I put enough on there. What do you think?

Also, this tractor doesn't have live pto.

I'd check that the PTO shaft isn't too long, sounds like it's binding up as you raise it. Turn tractor off, raise it all the way, and see if there's any slack when you try to disconnect the PTO shaft.

I'm with Beezfun, on this.

Mine is similar. I don't have the jerkiness when I raise it up. But it does have a "delay" when I go to raise it while it is running. It is not like this when I use a blade. Instant lift. I figured it was the weight of the tiller. But not sure.

Sounds like too long driveshaft or the ujoints are in a bind because they are being moved too far (too great an angle).

The lift is slow because u are lowering lever further than arms are going. So fluid had to fill cylinders back up. There's no point in pushing the lever down further than arms are dropping.

Make sure u grease the tiller and that both gearboxes are properly filled with good clean gear oil.

Have fun!

Ujoint are in too much of a bind. (too much angle) Just dont raise it all the way.
