All,
I have gotten a few PMs about the hydro hook ups and the blade jumping.. here is a quick note about this. If I get more questions I will do a better job of explaining this, pics.
The loader valve will work fine once you figure it out. Moving the joystick left and right there will be a second arrow on the picture on the valve pointing to the right. This is the 'power' or non-regenerating position.
My set up used a two way cylinder for lift, ie, one cylinder with two hydo lines into it. When plugged into the 'lift' ports, the blade goes up pulling back on the joystick and down pushing forward on the joystick. (no surprise here)
I used a meyer plow with two cylinders for the angle. Each cylinder has only one hose, the standard cylinder that came with the plow for angle. I plugged each cylinder into the 'dump' side of the loader valve so that putting the stick to the left makes the plow angle left, put the stick to the right and it angles right.
OK, so basically one hose to one quick connect for angle function.
What I found happening is the blade goes in one direction really nicely but jumps and bucks and stops etc in the other direction, this is due to the 'regenerative' function of the loader valve. What happens is that the valve is made so that when you dump the bucket both hoses on the cylinder are hooked to the hydraulic pressure. Inside a normal cylinder the push the rod out side has more area then the pull the rod in side, because the area of the actual rod is not counted, be so that if you supply pressure to both ports the fluid pushes the cylinder rod out (same pressure * larger area = greater force then same pressure * smaller area = less force) this forces the flow of oil from the hydro pump and the flow of oil from the rod side of the cylinder to the other side of the cylinder to happen more quickly, the dump action to happen much faster then if the hydo-pump just pumped in fluid and let the other hose drain as normal. Ok, so how do you fix this?
There are three ways. What I do is just slam the joystick past the right detent to the power setting, there are actually two right postitions, normal right at the detent any pushing harder you get to the power spot. If you slam the joystick far right the blade will angle right as you wanted it to. Going left works as you would expect it to.
The second way is to look at your joystick sideways, use left and right to lift and lower the blade, right should lift if you don't want it to buck, then use forward and back on the joystick for left and right angle of the plow. This *should* work but I have not tried it.
The third way is to get rid of the two single action blade cylinders and replace it with one double acting, (two hose) cylinder. This should get rid of the jerking but you may still have to slam the joystick full right to get the blade to move well since gravity is not helping you in this case like it did with theFEL bucket. This *should* work but I have not tried it either.
If you get stuck describe your hose / cylinder set up to me and I will post a red-black-green-white color code at the valve to cylinder plumbing and tray toexplain this better.
