Yes ! I think I posted a pick of the remote valves without the plow connected. Only one of the valves adjuster is available. The other had been broke off when I got it. I can get a replacement cable for $110.00. But I had never used the remotes until I got the plow. I am a pretty good backyard mechanic. It generally has to be a odd problem for me to search for help. I will take a pick of the plow and post it. Looking at my shop manual I see what they call a "Unload Valve". Looks to me that might of been open the last 15 years or more without using the remote valves ? Maybe I need to first find it and tap with a rubber mallet. I am just guessing but you have no complete circuit unless something is connected to the remote valves. But if the "Unload Valve" is open, cylinders not going to get the flow or pressure needed. I don't think the loader valve uses the "Unload Valve" ? If so, that ends my theory. Thanks I"ll post a pic of the plow.

Okay, so the loader is not involved with the remotes. The loader circuit and 3pt are working on the open center side of the system.
The remotes utilize a pilot line to mimic a closed center remote valve using the unload valve in an open center hydraulic system. There might be a restriction in the orifice plate on the unload valve that connects to the pilot line or as you said, the unload valve could be gummed up, but I would definitely look at the pilot line.
By the way, this setup is a Deluxe valve and is located in the parts book under “Variations“

It might be easier for me to try and connect to the second remote with the broken control cable. Is it a simple job to replace the valve end of the cable ? If I get that fixed, I could hook up to that valve. If it works I"ll be good. If not, pretty much confirm a problem with unload valve. I call the plow new but already had four or more years. I am in Northeastern Pa. We use to see plowable snow at least 15 time a year, 10 years ago. It snows more in the Carolinas now. I have a driveway 1/3 a mile long and plowed the most 3 times last year. If I would of waited a couple of days it would of melted. Sadly they have a unused snowmobile trail near the road, for a lot of years now. So that's why I did not rush this project. But the son-in-law was looking at a hydraulic motor driven post hole digger that goes on the quick bucket mount. I see one hose need to go back to reservoir.
Thanks,for your help.
It slightly snowed. I thought I could share a picture of my driveway with all. Most people said you got to be nuts to have a driveway that long. My wife choose a home site 3 X this distance, and 40K to run the electric. This site was 15K for electric.
If you look towards the bottom of the picture you can see the driveway. A slight veiw of the road is in the far right of the pic. Gravel went from $125.00 a tri-axle to $750.00 in 20 years. I am retired, but work aroud our property. I am a former HVAC, plumbing, electrical, mechanical Foreman for a college. I will brush off the plow and take a pic. My saving grace is a 2000 Chevy Silverado Supercab,I got on a bid on Iron Planet. The truck was checked in advance by Iron Planet with a report. 200,000 miles and everything is good but 4 wheel drive will not engage. I bid 3K (2006) and was the only bid. It came with a 80-inch Fisher power angle plow. (like new). It had a corroded solnoid that engages the 4 wheel drive. Cleand re-installed and worked ever since. It cost (Placed a add on U-Ship.) $300.00 to get here from Vermont over 500 miles away. I always put chains on the rear, but sometimes they are requried on all four wheels. I got stuck several times, because I had no idea where driveway was. Then I figured out I need to mark the driveway with 5-foot high post (rebar) before it snows. LOL.

Thank you have a great Christmas and New Year. I think another poster mentioned it but I have not found any way to tell what pump I have. A few numbers on the side, but nothing online I can find matches. I will take another look with my inspection camera.
Thanks again.
