Fruita CO | The only 4-piston pump I know of was in the early 2510. it was pretty much a failure, JD had a mod program to swap them out for an 8-piston. Not everybody took advantage of the program, I pulled a 4-piston out & replaced it just about 3-4 years ago...
The 4-piston was OK for steering & brakes, but slow for anything else, like a loader. Slow and jerky...
The 2120 being a Canada model, it may have a 4-piston, I've never seen a 2120... | |
