How To Raise The Loader Pressure on a KUBOTA TRACTOR

This is a hands-on DIY mod on a Kubota L4701, not a review or walkaround: an owner shims the loader's pressure relief valve to boost curl/breakout force, using a $150 eBay shim kit with gauge. He locates the valve, drains fluid, measures pressure before (2700 psi) and after (3000+ psi at 1500 RPM), and reassembles it step by step. Best for L-series owners frustrated with weak loader breakout power who want a real DIY fix, not just specs.
