This is a hands-on DIY upgrade video, not a review of the tractor itself: the owner installs an aftermarket hydraulic pressure-relief kit on his Kubota L3301 loader, gauges before-and-after pressure (about 2,350 to 2,480 psi, roughly 5%), and tests it lifting a heavy log onto a sawmill. He concludes the gain is modest and not worth chasing further. Best for existing Kubota L3301/BX/MX owners frustrated by loader lift capacity.
An owner-operator on his own homestead sharing an unfiltered, DIY hands-on test rather than a dealer or manufacturer perspective.
What this video covers
Pressure kit raises hydraulic pressure from 2,350 to 2,480 psi
Gauge connects to pressure side port below foot pedals, 13/16 fitting
Valve body contains plug, washer, shims, and valve stem, all must be removed
Added washer with no hole to boost pressure past factory washer
Lift capacity improved slightly but tractor frame felt stressed at max pressure
Verdict: not worth pushing past 2,480 psi, risk to loader and frame
