We have an 806 with a front end loader. Because we use three separate hydraulic controls for various functions on the loader, my brother rigged a triple set of valves on the right fender which are supplied from the right auxiliary hydraulic ports. To use this, we put a block of wood under the outer control valve lever (located next to the seat, right side) to lock it in the "up" position so the right auxiliary hydraulic ports are always pumping fluid. This has worked for years, but now we have a problem.
Some of the time the loader will lift very slowly, or not at all until you rev the engine up to fairly high speed. Even then it lifts very slowly. Seems as if we are leaking fluid through or around some check valve or unloader valve. If you put the auxiliary valve in the "down" position (thereby driving everything in reverse) it will raise the bucket at the normal rate in both of "up" or "down" position on our triple valve.
I thought it might be the control valve itself that runs the auxiliary port, but when I switched the lines to the rear hydraulic ports, (which are controlled by the inner control valve handle) we get the same results.
I have GSS-1344 manual and a parts manual, which describes the hydraulic control system, but am not sure exactly which of the check valves or unloader valves would be the cause, nor exactly where to look (other than under the seat.)
Any suggestions on this problem would be greatly appreciated

Today's Featured Article - Field Modifications (Sins of the Farmer) - by Staff. Picture a new Chevrolet driving down the street without it's grill, right fender and trunk lid. Imagine a crude hole made in the hood to accommodate a new taller air cleaner, the fender wells cut away to make way for larger tires, and half of a sliding glass door used to replace the windshield. Top that off with an old set of '36 Ford headlight shells bolted to the hood. Pretty unlikely for a car... but for a tractor, this is pretty normal. It seems that more often than not they a
