Increasing Hydraulic Pressure Kubota L2501 Tractor

This is a hands-on DIY walkthrough of raising hydraulic relief valve pressure on an L2501 to boost front loader lift capacity, using shims to go from about 2205 psi to 2600 psi. The owner shows accessing the relief valve on the hydraulic block, removing the plunger and spring, swapping shims, and reading pressure with a gauge at 2000 rpm. Useful for owners considering this modification, but it's an unofficial tweak that voids warranty and carries acknowledged risk.
