Can you make the 3 point raise faster on these tractors?

Tx Jim · Dec 13, 2019

Do you know how long it's been since hyd filters were changed & sump screen checked/cleaned? Other than that there's not a speed adjustment for raising unless the adjustment on control valve linkage is too wide not opening pressure valve enough. Be sure nut(key 28) is screwed in tight in control valve housing

If 3 pt has lift assist cylinders one could disconnect 1 or both cylinders to increase lift speed but that would lower 3 pt lift capacity.

Is your hyd pressure low?

SVcummins · Dec 14, 2019

Thanks for the replies guys . I have no idea the maintenance history on this tractor or if any pressures have been checked a friend just bought the tractor and asked me if he could change the speed of lift up I told him i didn?t think so . I told him to check the filters and after that check the Pressure

Tractordata shows hyd pressure of 4455 at 2530 psi. Hyd pressure control valve(key 5) possibly could be blocking flow/psi. There is a diagnostic coupling(key 10) to test psi. I would suggest to test pressure there & at rear scv then compare pressure readings.

My 4440 had snappy Scv response but slow 3 point. This was due to sloppy rocks haft valve adjustment. Another symptom was lots of play in the rocks haft depth control lever.
Also that Tra got had two assist cylinder, so was quite slower than a 4020.
