Trying to understand a bit more about our hydraulics, and put them to the best use.
We have a 784 which has two Kontak spool valves, and two levers on the right hand side of the seat for operating them. The 784 has a simple front end loader, just up (hydraulic pressure) and down (gravity assist) (front end is released with a cable). One of the valves has one pipe coming out of it, and the other has two pipes. All pipes terminate at the back of the tractor with screw-on type connectors. The single pipe going to the FEL is connected to the valve with two pipes coming from it.
Since we got the tractor and FEL, probably more than 20 years ago, the two levers were stuck, but we recently took the linkage apart and freed it up. We might be looking to add more functionality to the FEL, and/or get other hydraulic implements to better use the hydraulics.
One thing we noticed is that the double-acting valve to which the FEL is attached will always return to the neutral position when you let go of the controlling lever. The other lever that controls the single acting valve locks in the up or down positions when moved to those positions, and you have to physically move the lever to the neutral position to stop the pumping.
Would we be better off with the simple FEL connected to the single-acting valve?
Also, would the single acting valve have a float position? The linkage is quite worn, and the lever is at as far down as it can go when in the down position, on the floor, so difficult to see if it can go down further than the down position.
