What RPM do you guys run when working your tractor box blade loader type work? I am not referring to PTO type work. It seems the tractors hydraulic system can hit its limits at about 2600 RPM. Is there an advantage to running at a higher RPM? Has anyone seen a torque curve chart for these engines?

I have read that hydrostatic pumps like to be ran over 2000 RPM. For loader work I would consider as low as 1800 If it’s just moving something around but if I’m truly working with it 2000 or more. Box blade work max RPMs or maybe 300 less.

I run enough throttle for the job at hand. Need to go quicker? Push it up some. Don’t need as much? Pull it back.
Only when running PTO driven things like a mower do I generally go WOT.

You can access HP and torque curve charts on the Yanmar website.

This right here^^^^^^^^^^^^^^^^^^^^^

What tractor do you have?
With my 2038R I generally just let the auto throttle handle things, though I will bump the throttle up a few hundred rpms when doing loader work just give me adequate hydraulic flow. Box blading, normally 22-2600 rpms, depending on what I'm moving with it.

Agree with using what's needed to lift the load with the FEL. When mowing, I set the throttle until max pto rpm is attained digitally displayed on the panel. If I want to move faster on flat level ground, I kick it up. In closer quarters, moving slowly at full throttle is complete overkill. 1800-2000 rpm is sufficient. Every now and then, I find myself moving slowly at max rpm and drop it back down. Less fuel used and less wear and tear.
