Export thread

The PTO shut off while mowing and will not re-engage. Bypassed everything by putting 12 volts straight to PTO solenoid and PTO solenoid will engage the blades. PTO lights do not come on. Bulbs are good. NO power to Solenoid. Does anyone have a wiring diagram?

Don't know about States Side but down here the 455 was a badge engineered Yanmar.
My manual is only for European & General export, so might be way off the mark
However these might be of some help

Opps , brain fart , wrong models
Don't have a 445 book yet, no customers with one
Sorry.

This JD has a Kawasaki FI 20HP engine. These could definitely be of help. Thanks

mike shoot me your email, I have a PDF of the Deere Tech manual w/wiring in it
