Went out and tested few things tonight. Good news is solenoid valve clear up issue pto now comes on and shuts off with switch. The valve body was stuck.
Still have issue where pto shaft is slowly rotating whenever tractor is on Pto on rotation speeds up pto off rotating slow maybe 60rpm by my count. Could this be related to that valve sticking? Or is it what I fear it may be and the pto clutch(which i assume is what system uses as the brake) is worn and need replacement.
Still little lost with this issue wasnt expecting issues with under 200hrs and 3 year old machine. But you all have point me in right direction and I got time as no dealer can even get me in till middle of next month.
