Are you sure that its in the speed you what and not slipped in to neutral. Not driven a newer massey are they still levers for speed selection or electronic now

Are you sure there’s no error codes, they’re know for going through pto solenoids, I’ve had 3 on my 7726

Does the light flash on the dash when you engage the pto

Thank you all . turned out the fuse F28-15amp was blown. Replaced it and it blew again. As now in the middle of the baling season do not have the time to stop work.

To engage the PTO I am using the rear fender mounted button. To stop I can use the arm control button.
fingers crossed so I can get through the season

Will it engage on the arm?

Check the wiring underneath the tractor going to the front axle angle sensor as I have seen the harness get pulled apart before.

It shares the same fuse as the PTO switch

nope. it only stops from the arm.
