Thanks!! 486.8 hours. Removed belt released parking brake turned on heard pto clunk at least 10 times. Started the motor right up. Released parking brake pulled pto switch another 10 times no problem at all while running, never cut out once!
Great, you have just proved there is no problem with the PTO circuit, the module, or the engine.
Left mower running pulled each plug wire one at a time. Definatly (sic) each wire when removed heard engine idle down some both must be firing.
Even better news re: engine.
I guess I need to remove the deck and see whats binding? Funny I can turn the whole thing from the pto pulley by hand and its not that hard. Really appreciate the help and any more suggestions you may have to finish this thing!!!
Tell us which width mower deck you have please? 2 or 3 blades??
Then, IN THIS ORDER:
Yes, remove the mower deck.
Remove the black belt covers. TAKE A PHOTO OF THE BELT PATH FOR REASSEMBLY REFERENCE. (Although there is a decal on the deck itself.)
Loosen the idler pulleys and take the belt right off.
Stand the mower deck up on rear edge.
Align the blade tips next to each other and check for level alignment.
Keeping hands/fingers out of the way - Spin each blade individually. They should spin freely like an aeroplane propellor.
Spin the idler pulleys.
They (Idlers and Blade Spindles) should spin freely and quietly. Any rumbling noise will be apparent.
Tell us what you feel & hear?
Report your findings. Do not disassemble further before reporting. (!)
This won't take long and you can isolate the problem asap.
