Just today my 5740C shuttle shift started to be REALLY hard to move, eventually I could put it into reverse but it's almost like a bolt or nut has tightened by my action of moving the lever back and forth. Now it's so tight I can't move it into forward. Was moving bales and stacking them in a shelter, so was going back and forth a lot today. Anyone else hear of this? Is it an easy adjustment to correct this? Got about 310 hours on it, but it's over warranty for me (only had one year I think without hours counting). Thanks!
