Plow valve for a tractor

tessiers · Dec 14, 2010

I have a 6 1/2 foot fisher plow mounted to the loader of my tractor. To angle it I mounted the fisher control valve to the tractor with 2 hoses that plug into my power beyond and then plumbed the plow as normal. All seams to work well, does anyone see any problems with this setup? I figured it is open center by blowing through the valve when it was closed and that worked. What I could not find is how many GPM the valve could allow to flow trough it? And I also could not find the pressure the valve was rated for? The tractor produces 5.4 gpm at 2050 psi.

If you install a hyd gage in the system, you will at least know the relief pressure, by holding the lever in the extended or retract position. Are there any numbers on the valve?

Don't believe you should have any problem.

I had a fisher mounted on a 3/4 ton PU and I could use the angle function to push the PU back out of snow banks when stuck, and that PU was heavy when loaded with sand.
Also you are not running oil all the time, just when activating the valve.
For sure you eliminate the need for any flow restrictors.

I have un plugged the backhoe lines before and it is obvious when the tractor system goes into relief, the plow valve does not do that. There is flow through the valve when it is plugged into the power beyond even when the valve is in the neutral position. Do they make a gauge that will plug into the quick connects? what will that tell me? No numbers I could make out, I couldn't even tell which was in and out except I blew in one while pulling lever to lift blade and that was inlet.
