I am looking at a JD 450C dozer. Here is the problem with it.
It is a power shift model. It started with the steering getting weak. Then it got to where it wouldn't pull in higher gears. Now it will barely move and the hydraulics are very slow. The owner said he did some checking and some people said it might be a charge pump. I am not sure. I have worked with tractors and trucks but not on tracked equipment. What would I be looking to fix it if I got it? It has about 500 hrs on an overhaul and 60% on the UC and a 6 way blade.
