The tractor used to jerk back and forth (sometimes) when shifting from low to high, before finally kicking into high. Now it doesn't do anything. I replaced the switch on the floor, but that didn't help. I think its something with the solenoid valve? The repair book shows the valve body bolting on the side of the dual power housing? So I would assume the tractor would need to be split to access the solenoid valve?? Help! Rod or Bern or anyone with experience in this department. [Reply]   [No Email]

As Bern said, no need to split. You will probably need to take that cab mount off tho. Rod [Reply]  [No Email]

My guess would be a faulty solenoid. Make sure you have power going to it when you are in high, and if that checks out, then check the resistance of the coil. I don't have a spec in front of me, but it should not be 0, or infinite. [Reply]  [No Email]

But unless you pressure is constantly low a split will be required. [Reply]  [No Email]
