PTO Troubles

[ChuckB2]

I have an M5040DT. The pto seems to slow down when running a bush hog and I get into heavy brush.
Any suggetions?

Saying "seems to slow down" is not good enough.
You will want to know 100% before you dive into fixing that issue if it does have one.

Get a laser rpm gun and measure the speed of the shaft.

Then if that shows loss come back and we can go from there.

Wolfman, Thank you for your reply.
Tachometer is on the way.
I will post some better information soon.

I have talked with a Kubota dealer who indicated that it might be a problem with the pressure relief valve.
Any thoughts on that?

Does the cutter have a slip clutch on it? Does tractor rpm slow down too? Your tractor should have pto speed readout on the dash, what is it telling you?

Thank you both for the help. Sometimes all it takes is someone else making you think thru the problem.
PTO speed does not slow down and yes the implement has a slip cluth on it.
The clutch disc on the bushhog needs replacing.
But on a goodnote...I now have a new Tachometer.

That's a whole lot cheaper and easier fix than ripping into tractor. I'm glad that's all it is.
