I have a B 2650 that I bought new seven years ago, now right at 850 hours. I went out yesterday to till in my garden, engaged the PTO and heard the fuel solenoid click to shut the engine down. I disconnected the tiller shaft from the PTO and it did the same thing. Everything else works. I disabled the safety switch on the seat when I first got it because sometimes I have to get off and on. I’ve checked everything I can think of, I need help from the gurus… thanks

What about the PTO safety switch?

If you rise up on a standard seat and have the PTO engaged..... it should cut off.

The seat switch and the pto switch work together I believe as a double whammy to make sure the operator is in the seat when PTO is going.

Only the seat switch on mine and it has always worked the way it is. I wonder if there could be another switch. With the ignition on, not running, when I move the lever forward to engage the pto I can hear the solenoid shut off the fuel…

Are you sure the way you disabled the switch is still working? Perhaps the wires separated if you jumped the switch out.

Seems to be working as it should now. See the notes in the image below. (Image from the B2650 operator’s manual)

Not sure of what else goes into the OPC, or what the logic within the OPC might be though.

Thanks for the answers, tractor runs as it should without me on the seat, HST works, just wont engage the PTO. I see there is a switch on top of the linkage that leads into the transmission. Not easy to get to but maybe that’s what the problem is.

The parking brake also needs to be engaged to operate the pto while off of the seat with our B2650 tractors. I know you've bypassed the seat switch somehow, so that shouldn't make a difference, but it might depend on exactly how you modded the seat switch?
I found out about the park brake interlock for the pto to work while off the seat when my ajustments to the brake pedal travel at maintenance time caused the associated park brake safety switch to not contact the brake mechanism anymore when park brake lever engaged and locked. It's behind the dash panel, and I adjusted the switch to work correctly again.

Thanks, I’ll check that out. I do my own maintenance and understand the workings of the tractor, all the safety protection is a story…
