deutz agrotron pto problem

[D C]

I have a deutz agrotron 4.90 and it jumps out of the540 pto gear every now and again. Any ideas on what the problem could be? Fairly happy its not the cable out of adjustment as it still does it with the cable disconnected.
Any thoughts much appreciated

Electric switch? Or is it a hand clutch job?

Short on the switch circuit?

Its more a gear problem I think, its ok in 1000 speed

When you disconnect the cable, can you move the lever on the side of the PTO gearbox so that it "feels" like it's engaging better?

It's likely to be either the selector fork, or if it's frequently not been properly engaged when changing between 540/1000 causing the gears to grind, it could be the teeth.

When it jumps out of gear, the selector fork should move the lever on the side that the cable from the cab connects to. If it doesn't, it's most likely the fork.

It's not likely to be shaft bearings since there's no problem with 1000.

Yes it feels like it engages properly, when it jumps out it always goes towards 1000 if that makes sense?

As said most likely the selector or the gear is worn causing the throw out problem.
Dad had a nhts115a doing the same thing.

How Is it to get in bits do you need the top off and then will it all come out backwards?
