New Holland TC40D
Hello, I'm having power problems problems with my loader and 3 point. They have very little power at low idle and not as much as they should have when I throttle up. I replaced fluid, filters, and o rings on the suction line. The suction line screen had some shavings but I didn't think it was excessive. No chattering, just poor power. Hydrostat seems to be work but does wine it the cold weather. I also replaced the o rings between the pump and the diverter valve. About 1500 hours on the tractor.

Best thing to do would be to check the pressure. Put a tee in one of the loader lines & run it to the end of the cylinder stroke & check pressure. Should be around 2000 psi at full throttle.

I replaced the hydraulic pump. It works the way it's supposed to.
