Have a 4000 Industrial. I have been using it for the last couple years to do odds and ends and some fairly heavy bush hogging. It worked fine until this fall, when within a short period of time the 3 point hitch would not lift. It is totally dead now and I am unable to lift even the yoke. I can grab the yoke and manually lift it up and down, and the piston goes in and out but there is no hydraulic pressure behind it. Any ideas or suggestion? The implement/draft control lever does not seem to go completely "horizontal" or "up" and I has wondering if this could cause the problem.
Thanks for any help.
