The attached pics are from the WSM for my tractor, an L3400. It shows the cylinder safety valve being set for roughly 3000 psi (2845-3277 psi), which is well above the normal relief setting of 2250psi, and the hydraulic diagram shows where everything is plumbed in relation to each other. The lowering valve (6) is shown in green, the cylinder (7) is in yellow, as is the safety valve (8).

... A question for the OP.. have you had the tractor since new? The previous owner may have tried a few things.
