I have a Kubota L35 that has trouble going into gear once the tractor is warmed up. After about 15 minutes of constant use, the tractor doesn't want to go into gear. Lets say i have the selector in 3rd gear going forward. I then stop, take it out of gear and put it in neutral, then put in in forward or reverse and select any gear say 2nd. It wont go into gear unless i wiggle the gear selector or once in a while mess with the forward and reverse lever. Lets say I'm in 4th gear going forward and i shift to 5th gear. The tractor will either hesitate then go into gear or completely not go into gear and have to wiggle the control.
