530 differential lock getting stuck

1031D · May 19, 2014

How is a differential lock on a 530 supposed to work? If I step the pedal down the rear end locks as it should, but I have to use a pipe wrench to disengage it! I recently had the brake apart and the large spring is still inside. Tractor sat outside the last year or two so could it just be rusty? Something else to look into? Is it supposed to disengage by stepping on the brakes?

The pedal shaft should rotate freely, so it can release.
If you are turning a bit there is still pressure against the the locking collar, since the rear wheels are turning different speeds when turning. To get it to release you have to turn the steering wheel back, or give one of the brake pedals a brisk kick to free it.

Loren, nothing short of a good tug on the pedal or the other day using a small pipe wrench will disengage it. Maybe I will take it apart and lube it up.
