Read articles →An owner-operator on a Kubota B2601 documents his attempt to boost front-end loader lift capacity using a B Expanded hydraulic pressure gauge and shim kit. He baseline-tests with a heavy firewood tote, measures factory PSI, locates the pressure relief valve, adds shims, and retests, finding the tractor was already within spec and gains were minimal. Most useful for B2601 owners curious about hydraulic pressure adjustment rather than anyone expecting a dramatic fix.
An owner-operator sharing a real hands-on DIY experience from his own farm, with no apparent commercial affiliation, though he does name the third-party kit he purchased.
Use a B Expanded hydraulic gauge kit, hook it to the fitting after removing the loader attachment, start the tractor, and read the PSI on the gauge.
It is located behind the back wheel next to the filter, near two hydraulic lines with a nut or cap covering the plug and spring.
The owner added shims raising pressure from about 1,900 to 2,150 PSI, but found it did not make much difference lifting the test load.
The owner found the tractor was already within factory spec around 1,900 PSI, suggesting the lift limitation is just how the tractor is made.
