Rotary Cutter Brushog boggs down too easy?

[SPYDERLK]

that's what I thought. you last handfull of posts have had nothing to do with the ops problem... you are just looking to argue.

go argue with the wall.. I'm dropping you into the ignore bucket.. plenty to do other than listen to you whine while waiting for the op to get some data back to us on his non spinning pto shaft.

see ya.. er.. rather.. no.. won't see ya.

Good.

733 hours seems too soon to have worn a clutch. Unless ALL 733 hrs were very heavy PTO work.

What is an "adjustable post drive"

Do you have any pictures of your setup, that you can draw a little arrow to everything that is stopping?

If you cannot confirm the PTO shaft is dropping, we may be back to a slip clutch or shear bolt issue.

Sorry not post drive. "drive-line"

733 hours ain't even broke in hours for that machine.. or should not be.

does this mower have a slip clutch that installs right aft of the tractor.. or one at the mower gearbox. if no slip clutch, then is it a shear bolt job that has possibly sheared allowing the pto yoke to just spin on the mower gearbox input shaft... sometimes the shear bolt galls and parasitically turns the mower till it hits resistance.

bottom line. you need to know if the pto stub on the tractor stops or not. or if rather it stays spinning, and a clutch or other shear protection in the driveline has instead failed

a pic of the setup may help us toss usefull ideas at you... but we need to pin down if the driveline is turning. there are actually some bad, rare possibilities that, say.. the pto shaft is turning, the drive shaft is turning, and the input shaft is turning.. but the blades stall. could be a chewed up input or output gear.. or a stripped hub on the blade carrier / stump jumper, if equipped.

but we really need to determine what is and what is not spinning with tractor pto engaged and mower stalled.

if for safety or mechanical reasons you don't feel comfortable going past this point, then let us know what your tractor mechanic tells you.

good luck, be safe, and let us know what you do or find.

ps. for safety.. don't get near a running pto powered device.... don't touch shafts or shields.. don't ever try to stop anything by hand or touch anything back behind the tractor if the engine is running... again.. be safe.

Thanks guys for taking an interest in this problem. 733 hours on my NH TC48da. I cannot confirm if the PTO is actually stopping - I assume it is stopping because the adjustable post drive that attaches the brush hog to my PTO is stopping when I look behind me to see what is happening.

I am going to call my local tractor expert to come look at it. I'll let you know.

i knew what ya meant.

It's very clear to me you all are just tying to help and I am grateful. There is definitely something wrong beyond my experience. I've had the tractor for 3 years work it often used on many projects.

Good. Whatever it is needs immediate care. Anytime the bushog slows w/o the tractor engine slowing at the same time it means something is slipping. That causes a lot of heat somewhere and can ruin parts pretty quick in some cases.

if the tractor pto is stopping.. the engine should be stopping!!!

if the engine does not stop.. but the lil pto stub does. VERY BAD!.. means it's slipping!

can't believe this thread has gone 13 posts and no one said that....

I agree. In his original post he mentioned "stalling" I read that to mean that the tractor was stalling. Reading it again, it appears I read it wrong as he says his mower is stalling, not the tractor.

We certainly need to narrow down what is actually stopping. Sometimes it is difficult to tell, with guarding and drive line shields an all.

Be safe whatever you do. And if you ain't comfortable going any further, by all means get someone there that knows what to look for.

Update: I had my tractor technician come out and take a look- PTO clutch is the problem. Tractors in the shop now. Thanks for all the help.

Before you authorize going into the tractor, ask about adjusting that clutch. They do burn pretty quick when they slip, but its possible you caught it quick enuf that an adjustment will help enuf to get some more life out of it. The thickness of the remaining friction material will be a key consideration on whether to try to "save" that clutch.

So I am assuing you are talking about the clutch in the tractor and not just the slip clutch on the PTO shaft I take it??

Seems kinda odd that it is toast with only 733 hrs on the clock. Is that an independent PTO, or 2-stage clutch?
