Allis D14

Check the Power Director very closely for wear. It should not engage at the very end of it's travel in Lo or Hi. Also, check the transmission 3rd gear very carefully--it's the trouble spot and weak link. Listen for any whining bearings in the transmission or final drives, too. Take it up the road and wring it out. These are dandy little tractors if the transmission hasn't been hurt. Good luck!

If the Power Director did not want to stay engaged in Hi range it"s a pretty good bet that the clutch plates are badly worn--this is common for Hi range. Sometimes it will stay engaged and work fine after the oil warms up. The lever on the left side of the quadrant sounds like the Traction-Booster lever. Does the quadrant have a bunch of notches in it? This lever can actually regulate the depth of an implement through the Traction-Booster system, which is one of the really neat things about the D14. The regular hydraulic lever works to raise/hold/lower--the Traction-Booster lever can be set to increase or decrease the sensitivity of the hydraulics. Hope this helps and good luck!
