HI, I'm new here. I didn't even know that a plowing forum exsisted on the Internet! I've been missing out! Anyway...I have a Meyer model ST-90 plow with a E-47 pump/motor. Now i'm having an angling problem. I always park the truck with the plow straight. When I start the truck up..the plow will angle fine to the left, and then to the right. But, if you angle the blade all the way to the right, it will not go back to the left. It will stick there. You have to either manually break it loose, or push on a rock/tree/snowbank. This problem has been around for about 5 years now..ever since my dad blew a hose and used the wrong kind of fluid to re-fill the resevoir. Since then, we've changed the fluid three times (the third time was tonight), replaced the solenoids, and replaced the valves. Still the problem persists. I'm thinking that it's one of the rams that isn't freeing up when the plow is angled that far. Any ideas?
