PTO Clutch/Brake

[thcri]

I have been patiently waiting for a good snow storm all winter. As I see it, it is not going to happen. Today we made a record and hit 70 degrees. Yes I am in Minnesota. In fact you can ever see a tint of green in the yard. So I am now going to wait patiently for the mowing season.

My question is I have heard of some of the problems the boomer's have with brush hogs and PTO Brakes. It was awful expensive to fix if my memory serves me correctly. Some one had said a person could buy a external brake/clutch or something like that to protect the Brake on the Boomers. Does anyone know what I am talking about and how much are they and can you buy them from like a Tractor Supply.

The overrunning PTO clutch is what your looking for.
Tractor Supply has these for around $50.
It attachs to your tractor PTO shaft, and will lock up one way to run implements and rachet freely the other
when the PTO is shut off saving wear on your PTO brake.

Here is some good info on PTO brakes.http://www.tractorsmart.com/main/otherlinks.htm look under Tractor Power Take Off.
Independant PTO.

I see the PTO clutches or overrunners as Tractor Supply called it. My tractor has Live PTO on it along with a Hydro Transmission. But I am assuming that I still have the PTO brake that can wear out from the brush hog continueing to run?

My Kioti DK has the independant PTO. so I installed the overrunning clutch to save on the brake.
I really do not want to tear the tranny down in the future to replace a brake, so its much easier to add the clutch.
The only downfall is that the overrunning clutch adds about 3 1/2" to your Pto shaft length, so I needed to shorten the PTO drive shaft on my brush cutter.

Murph, I think this issue was only on the Class III Boomers, not Class II. I don't think Class II Boomers have PTO brakes. I say this because I have used the following procedure, gotten off the tractor, started unhooking the cutter and found that the blade was still slowly spinning, which would imply there's no PTO brake.

The way I use my Woods BB60 is (see if this is right according to the TBN brain trust /forums/images/graemlins/grin.gif)

STARTING
1. RPMs just above idle
2. Depress clutch, move Rear PTO lever forward, slowly release clutch to get blade spinning.
3. Increase RPMs until the 600 rpm light just comes on, then back RPMs down a bit.

Reverse the procedure for stopping.

Mike,

I guess that is what I wanted to hear. There was some discussion on it before but couldn't find which tractor it pertained to. I have used the bush hog also and when disengaging the PTO it seems like it runs forever before it comes to a stop. So I guess I will just forego the extra bucks for it.

Thanks a bunch
