Plumbing loader on 300 Farmall

Anonymous-0 · Jun 9, 2008

just bought a freeman loader for my 300, it came with a 2 valve spool i was gonna use that to power the loader because I find the hydratouch handles a little far to reach for continous hydraulic use, so is there power beyond possiblilties on the 300, if so where would a fella plumb it in. I know i could just hook it into the quick couplers on the tractor a tie the handle back but that would be a last resort. any feedback would be greatly appreciated.
Also is the clutch on the 300 normally heavy to push, i find mine wicked heavy, is this normal because of the TA?

Thanks
Matt

Matt: If the spool valve that came with your Freeman loader is a power beyond valve, just tee into the high pressure line between pump and 300 own control valves. high pressure is the small one. I ran my 300 that way for years, 5 double action remote control valves. I took the steel lines off, cut the high presure line about 1' from curve at back end. A welder brazed fittings on each end of the cut. then it was just teeing in and mounting the valve.

Matt: I don't know what your comparing 300 clutch to, it's definitely not the easiest clutch to push down. Your left leg will toughen up, once you get that loader mounted.

Matt,

I'd be really careful about how you did what Hugh suggests since the most obvious way of plumbing it would leave you without any safety valve or pressure-control mechanism between the pump and your loader's control valve -- presenting the possibility of overpressuring the pump and/or loader hydraulics.

Dick: Any power beyond valve should have it's pressure relief system. May be there are some that don't. I know the one I had did, and the setting on it was adjustable.

Is a Tee is the proper connection to make here? This is an open center system.

If you simply tee off the high pressure line, you create two paths for the oil to get back to the reservoir, and the oil will always take the path of least resistance. Pull the lever on the loader back, and the oil will just flow through the stock valve stack, and back into the reservoir without raising the loader. To get the loader to work, you will need to hold back one of the stock valves to block the second path while operating the loader, and release it when you release the loader valve to prevent the pump from overheating as it squirts the oil through the relief valve.

My understanding is, you want to connect the loader valve stack IN-LINE with the high pressure line. Pump to IN, Power Beyond to the tractor's stock valve stack, and OUT to the fill port on the reservoir.

mkirsch: I guess I best spell it out exactly how I did that plunbing. I cut my high pressure line, a welder brazed hydraulic fitting on each end. Power from the pump went into power beyond valve. The discharge from the power beyond valve hooked back into high pressure line going on the the 300 factory valve tower.

I used it that way close to 20 years. It gave me 5 instant remote valves, Bear in mind one could only use one maybe two if small demand, at any given time, 300 just doesn't have the GPM for much more. I had my loader hooked to the power beyond valve if it was on tractor. I could also use any one of 300s 3 factory remote valves at any time, my only limit was GPM.
