755 PTO questions

[Harry in Ky]

Can someone give me a brief rundown on how the pto works on a 755? The parts layout shows a hydraulic clutch pack, with a manually controlled spool valve? Is there an electric dump valve somewhere that could possibly interupt flow based on signals from a seat switch or operator safety circuit?

shoot me your email and I'll send you a PDF of the tech manual, it shows the theory of the operation and the repair

Short answer is the manual valve is held ON by an electromagnet that is shut off when the seat switch opens.
