My BIL installed a secondary electric pump unit on his WD as his factory hydraulics crapped out. He is trying to get power up and gravity feed down and perhaps power up and down if possible on his three point. The pump he installed has one solenoid valve and I believe to get power up and down he would need two and a 4 pole switch. He was going to use the Allis single action cylinders on the three point but wound up buying two way cylinders. Can anyone suggest how they need to be plumbed? One issue he is having is that if he applies power down he can get force to the ground but when he releases the switch his blade will come up off the ground about 1/2" or so, any ideas why?
