T-200 Wont Move?

[rageatv]

I have a T 200 skidsteer that has been working perfectly until the other day I went out for some minor work, fired it up, pressed my green buttons to unlock, and she acts like the brakes are stuck on. They are not obviously! Bucket works fine, but she wont move. I have tried everything, fuses....reset, on and off and nothing. Any ideas?

Is is possibly a bad switch for the 'parking brake'. Not sure if it is normally open or closed, but if you disconnect the wires and see what happens, then try jumping them together.... Also could be a bad coil on the brake control valve block. Check for voltage at the coil when the brake should be released. Also, is there a brake relay in the fuse panel? If so swap it with one of the others in the panel.

The brakes are hydraulic and for some reason your brakes are not releasing. There is a small hydraulic line going to each drive motor. If you follow the line you may be able to see where they go and trace the problem from the actual brakes to whatever it is that releases them. I'm not sure but I believe the brakes need hydraulic pressure to release. I do know the machine has to be running to release the brakes.
