TC35D PTO won't stop turning

[tly]

I've noticed that my PTO won't stop turning when lever is disengaged. It isn't under full power as I can stop it by lowering the bush hog. Any ideas?

the rotation of your bush hog may be turning it after you disengage.

sounds like the pto clutch brake failed. They fail under "high inertia loads", like a bush hog. There is an update for it.

It's not the enertia from the brush hog. The shaft turns even when there is no implement attached. What does the update involve?

What happens with a rotary cutter is that people will disengage at full PTO rpm and the PTO brake has to stop the cutter's rotation. After awhile, the PTO brake wears out and starts to fail. Most of us have found that we can lower the engine's RPM to idle and let the engine slow the cutter. Once the cutter has slowed, disengaging the PTO lets the brake stop the cutter with much less effort. The PTO brake and hydraulic clutch are one integral unit. There have been updates and improvements on this mechanism as Jbrink64 indicated. One of these updates/improvements relates to a tab that can be damaged and cause the brake to not set properly. Even after this update, engaging and disengaging the PTO at low rpm will ensure a very long life. I have a tractor built in July of 2000 and its PTO clutch/brake works like the day I brought it home because I'm very careful to reduce the shock of high rpm engagement/disengagement. I'm not saying that you have not operated properly. I'm just offering this advice on the chance that you are not aware of it.

I have always engaged or disengaged my PTO on my tractors at idle speed - never ever any higher RPM than idle.

I have a TC35 hydro. What is the proper idle rpm? My tractor idles a bit over 1000rpm. Seems a bit high?

My TC45 idles at 1000 rpm + when warm also. Compared to 2600 rpm for 540 PTO rpm, 1000 rpm is very reasonable.

Thanks for the info. I always engage the PTO slowly but at a higher RPM. As far as disengagement I never thought it mattered but apparently it does and I will change my habits now that I know. I suppose getting this issue corrected is going to take a trip to the dealer. Anyone have any idea of what this entails or costs?
