CM- that's good to know. The valve, a Prince from Surplus Center, was only $70. They had told me the same thing about lightening the release pressure setting at S.C.
I don't want to cause trouble for the tech. I spoke with, so we'll let Daryl sort this out at their next group meeting. They aren't THAT big a company.
If we never get any snow, I will never know about the plow and the valve. I think the cylinder on the 2000 plow may be the same size, which means it should work for me, too? Mine's a 78 blade.
I'm ok with not relaying the tech's name back to Daryl, and I don't think it was about getting anyone in trouble - I had mentioned I would see who spoke to whom. No big deal- I also asked Daryl to let those who need to know what the informative answers are.
Your blade is 7.5'? You have a DA single cylinder on the center to left side of your model 1000?
It will only work when trying to extend the cylinder. There is no way for it to be effective when trying to compress the cylinder unless they are using a different setup. Possibly a PRV that has its own dump back to tank?
I believe it to be a crossover only valve. They use two cylinders on the next model up, the 3000 series, also with a crossover, and because of the extra size and weight, and what you and others have stated about the 'push me, pull you', (my words) type of forces on a blade I can see how the crossover would be more effective, with one cylinder on each side of the blade.
A crossover valve ONLY protects the extended corner of the blade.
You hit a curb and the oil dumps over to the other side, but who plows snow away from the curb to the center of the street?
We plow to the ditch side (right side) and when doing so the right corner is retracted so the crossover offers no protection.
It ONLY protects the extended plow corner and when is there a curb in the middle of the street (or the drive)?
OK, so your drive has lots of roots or rocks in the middle so then a crossover can serve you.
On a truck plow at 30-40 MPG a crossover will be an asset but on out slow tractors I am of the opinion that the $$ is better invested elsewhere.
Rely instead on a good trip mechanism with well adjusted trip springs.
Here's what comes to mind for me, from my personal experience with the single cylinder DA and crossover mounted on the center to left side of the blade. Yes the blade is most often retracted when plowing a drive/roadway, toward the tractor's right side. This means my single cylinder is fully extended on the left side and that corner of the blade is farthest in the middle of the drive/road, so the crossover can't help me if I hit an immovable object with my right corner. The springs would have to make the mouldboard trip forward to keep from extreme forces being sent to the blade or the loader arms.
However, when I push dead on into an existing snowband of several feet of depth or more and there is too much force at the bottom of the blade the springs may also trip. Sometimes when I go to push the snow real high and the tractor's front wheels climb the bank, if the blade is angled, either the blade will slide in the direction it's angled to, OR the crossover will make the blade release and it will automatically angle toward the opposite direction. Trucks can't do what a loader can with a FEL mounted blade; and that is where I think the crossover does the most good for protecting the FEL arms. Think about that the truck plow is connected to the chassis of the truck. The FEL mounted blade is only connected to the QA plate and thus to the FEL. The loader can/will experience extremes the truck doesn't encounter because the chassis moves with the plow of a truck. If a FEL torques because of angles/pressures not seen by a truck plows limited ability to raise off the ground like a FEL, the tractor can suffer serious damage to it's FEL and it's connection to the tractor frame.IMHO. Please give feedback if you feel I'm in error on these points.
