John Deere 450 Dozer Wont Move - I have a john deere 450c dozer that doesn't seem to have any power moving forward or backwards. It has enough power to move itself but that's about it but very slow. When i am trying to get it moving when it is cold , sometimes i can move the clutch pedal up and down about a 1/2 to 1 inch and the trans pressure will go up and then start to. Check for worn bellcranks, balljoints and such. Also, the directional spool may be misadjusted as well. We have a small bulldozer, s/n t0450jx139324, that we were using to clear fences with and the operator told me he had a problem. The dozer starts fine, but wont idle up,. We have a 1989, 450 g dozer that will not move, we had been using it to move some brush, went to back up and it stopped working, we changed the filter, drained the fluid,. My jd 450b crawler/loader won't move. It stopped driving in either direction while lightly pushing a small bucket of dirt. Previous to that (when we purchased the machine) it. Went to go push it back in the yard to do some body work but it won't move! The transmission is chained up and engine/clutch are still out. The front 2 wheels spin freely the back 2 are locked. So here is the problem. when i pull back on the right stick the dozer stops. The left track does not turn. With or with out a load. On flat ground it turns fine. I checked the fluid. I have 1966 450 dozer with the hlr and when i put it in r it wont move backward. I tried going through the speeds on the left hand side and i noticed them grinding into each gear. Everything on the loader works and even the hydraulic remotes work but the dozer will not move. Any ideas of where to start. I checked filter in front of the radiator and the lower. Most common problem on 450s is the linkage coming loose that connects the mechical clutch pedal to the trans. Most likely it is a bad connection in the computer harness, or a failed sensor.
