I've just put together a new 2-ton capacity dump cart, since the old 0.1-ton Sears cart I have just isn't cutting it (two scoops of dirt from the loader and it barely rolls). More accurately, I have a 2-ton capacity cart, period, because until I add a hydraulic cylinder, there will be no dumping (the bed pivots at the rear, and I can barely lift it empty).
It has mounts already welded to the frame which I measured as about 34.5" inches apart. The manual says it supports a cylinder with a 24" stroke and up to 4" bore. Most of the cylinders I've seen with those specs have a retracted length of 34.25", which I figure is close enough to my rough measurement to be the correct fit.
My first question is about which cylinder to get. I see price ranges from around $175 to around $400, depending on bore, pressure tolerance, and style. Does it matter whether it's 2500, 3000, or 3250psi? Would a 4" bore make a noticeable difference versus 3.5", in terms of lifting power? Would welded really be more sturdy than tie-rod in this application?
Second, I need a sanity check on just how to connect it to my Kubota BX25.
There are three hydraulic connectors on the back - outlet, inlet, and power beyond. The backhoe connects to all three of them. When the backhoe is off, the outlet hose is connected to the power beyond connector, to supply hydraulic power to the mower and 3-hitch lift cylinder.
So to power the dump cart cylinder without leaving the mower deck at the mercy of gravity, I need a 4-way control valve with an additional power beyond port, to which the inlet is routed when the lever is in neutral.
Is all that correct?
Any advice on the size (and type) of the fittings and hoses to shoot for?
