Hello everyone, I joined to get information on a 2008 Ferris IS2000Z p/n 5900619 s/n 2000381406 that has a very odd problem. I just purchased this machine and it's my first Ferris, that being said it has a problem that no forum thread has had a thread about. The PTO is always energized, after about an hour of cutting it will disengage but only briefly. When you turn the key to the ACC. position you can hear it energize, removing the relay will not stop it, the wiring to the switch looks to be OEM with no tampering. The switch opens and closes as it should. When it does disengage, if you pull the PTO switch the blades go right back on as normal.... I'm stumped on this one. Thanks in advance!
