Hey guy's mounted my mmm last night and now my 2000 pto doesn't turn on. 540 will work in 540 position. It will not work in 540/2000 position. The 2000 only position doesn't work either. I haven't used this since last fall. The dealer replaced the linear actuator this winter. First time trying to mow this year, no go. Shouldn't the mid pto turn on without anything attached? Is there a position switch for the pto selector lever? Any suggestions?
