I bought a used Takeuchi Tl130 which I've had for a few years. When you start the engine, the right track will go in reverse, but not the left. It goes forward fine and turns fine. If I let the engine warm up for ten minutes, then when I try to reverse the left track it will inch back a bit very, very, slowly hardly moving, then pop and it goes backwards fine. Hydraulic fluid obviously needs to be heated up well. After that, the machine runs fine. Anyone know what's going on?
Sounds like you have a brake not releasing. Note, I have no experience, with your machine, just a WAG...
