Are you saying there's nothing unusual with the lift not being able to hold position and that I have the "jumper" line connected properly? I knew the early models didn't have the greatest system, but I never knew they wouldn't even hold the lift at a certain position. How would one ever plow with that setup? Guess you'd have to use a towed type rather than 3-point plow.
I also looked at my service manual but it shows multi-port valve setups that this tractor doesn't have. There are two lines that run along the left side of the tractor and they both connect to a valve body on the left side of the differential housing with 3/8" pipe. This valve body also has a 1/2" line coming out the rear of the valve--this one was originally capped off, but now I have the "jumper" line connected to it.
