John Deere 350-B Dozer - Hydraulic Trouble?

My 350-B seems like it has no hydraulic pressure. Seems like it doesn"t even want to move when it gets warm, and when you engage the reverser, it doesn"tseem like it does anything at all. The only real power the machine has is curling the bucket. I did just replace the hydrauic filter, and part of the old filter had disinegrated into the case. The more troubleshooting information I get, the better, because I don't have a manual. Thanks so much for reading!!
 
Post your question on the crawler forum on this site. There are a few JD mechanics that could help you. Dave
 
The hydraulic system that operates the blade or bucket has absolutely nothing to do with the machine's ground travel. Front blade uses a front-mounted Cessna gear pump and a two hydraulic filters inside the side-mounted hydraulic tank.

The reverser - if it has one - is self-powered and has a small pump built into it. Reverser also has its own paper filter inside the reverser case.

One has nothing to do with the other. Seems you'd better get yourself a manual.

350B has a spring-loader torsional isolator assembly on the engine-flywheel that drives the reverser (if your machine has one). If your's does NOT have a reverser, that the flywheel has a single-disk dry clutch.
