KL130 Front End Loader | Kioti Tractors
I believe the 2000 psi on the loader is a general low setting on certain tractors for safety reasons.
With the relief set at 2000 psi, certain tractors can lift about 1,155 lbs at the pivot pins. What that means is to tilt the load back so the mass is over the pins.
A smaller tractor with the loader relief set at 2000 psi might do well, but if the loader relief psi were to increase, and the loader bucket fully loaded, just might tip the tractor.
So if the loader is installed on a larger tractor, and relief set higher, you would probably have an increase in load potential.
The loader probably has the potential to go to a higher relief setting, and you could try and see if your tractor can operate safely.
You might call the tech's at your dealer and see what they recommend.
Extra weight or loaded tires might affect the balance or lifting potential.
If you do have to keep the 2000 psi setting, that will affect your 3pt lift potential.
