Hi there, I've got a Montana R4933HST tractor which is an LS 4020. The PTO used to work ok, then one day it wouldn't shut off. I learned if I tapped the solenoid with a screw driver then it would shut off. Last night I used it to do some rototilling for a couple minutes and it shut off fine but when I went to rototill today it wouldn't engage. I pulled the solenoid out and applied 12V to it on the bench and the valve clicked open and closed. So I sprayed it out a bit and reinstalled and it still wont engage.
When it's on the tractor, and the switch to the PTO is on there is a magnetic field on the solenoid so some power is getting to the valve. I was hoping the valve was just stuck but it seemed to work ok on the bench, or maybe it's just weak. Any suggestions on what to do? I'll probably pull it off again tomorrow and test it on the tractor but not with the tractor running. The part number is 40007701 but it's quite expensive.
Thanks for your help.
