Hi there i have a 4wd john deere 2650 tractor which has a hydraulic problem and im looking for a workshop manual. Can anyone help please?
Hi there I think I may have a manual on disc. What is the problem ?
Sorry for the late response. If you could email me the manual that would be great. The rear hydraulics for the 3 point linkage is very slow and down on power, the hydraulic filters and oil have been replaced but its still the same. Its just that i want to get a good look at the manual before i start taking anything apart, im suspecting the internal pump. Cheers for the reply Leo
The internal pump has nothing to do with the rear hydraulics. The pump in the gearbox is a charge pump, it scavanges the oil from the back end and feeds the front piston pump with a constant supply of oil. It also supplies the pto, four wheel drive and hi/lo. If the internal pump was bad you would be having problems with all the lo pressure circuits. I will be back home in a week or so, I will look out the disc.
