New Holland PTO problem

[rpatterson872]

Guys.... I’ve got a New Holland T7.185 and the PTO seems to be starting up very sharp with no revs tried calibration but doesn’t seem to make a difference, some times it’s fine and other times starts up very sharp. Any help on how to cure it would be greatly appreciated. Thanks

Is it new? We have a 260 that started doing that but after a some time it sorted itself out

Had a t6.175 that would periodically start pto with jolt. After numerous warranty investigations it turned out to be the internal bracket loose that held a speed sensor. Sensor has to be at a set distance and whilst trying to measure mechanic discovered it moved. Problem solved.

We had this with a T7, if you did a h8 reset on the Pto calibration it would be ok for a few days.

In the end it was the pwm Pto solenoid, changed that, reset it and it was ok again

Hi thanks for the reply, how do I do a h8 reset? Is it a laptop job with the dealer?

Unless you've got a diagnostic plug and know your way around the menus id get your dealer to do it. H8 menus really need to be avoided, too much to go wrong if you press a wrong button
