I need Your help and advice on solving a PTO issue on my 3240 (580 hrs, I am original owner). A few weeks ago we've got about 6" of wet heavy snow, which I was cleaning with 353 blower (thrower?), and suddenly PTO stopped working. First, I thought it was a problem with the blower, however, after disengaging blower the PTO still wasn't working. I replaced the actuator, solenoid and belts. When I pulled a switch the actuator works as well as all pulleys, but PTO still doesn't engaged. Vacuum works (i checked with my finger). I was thinking that perhaps a switch went bad, but if that would be a case then the actuator and solenoid would not work.(I think). If any of You had similar problem and/or know how to fix it kindly please let me know. Any advice is much appreciated.
