  • Position control interesting problem?
  • I have been using my 1952 Ford 8N to run a 4' Bush-Hog Squealer lately. It has been extremely hot here and I find that after I have been running for some time that, when I attempt push the handle down to lower it, that there is considerable resistance. Everything still works as it should but there is resistance there which is not there when starting out. Hydraulics were rebuilt about five years ago with fresh fluid and also I changed the fluid last year. Using proper 90 weight oil as was recommended here. Dip stick for fluid shows it is up to correct level and does not show any water mixed with it. Tractor sits covered when not being used. Your thoughts?

  • Once you get the lift problem fixed, or even if you don't, save a bunch of wear and tear on the hydraulics and cutter by hanging the cutter on a set of limiter chains.
    Once I set the correct cutting height with the chains, the hydraulic touch control lever just stays down until it's time to swap implements.

  • Remove side cover & look and feel for binding. One suspect might be the control valves sticking in bore or broken spring behind intake control valve..it helps push it into lower position.

  • I have never removed a side cover. I would leave that to someone who has. I can say that the reaistance seems more a hydraulic pressure than a mechanical one. I will spray all external parts with a silvent to see if that helps. Dave
