Hello everyone. Has anyone else had an issue with the 3pt lift lever "creeping down" while the tractor is running? If so, how did you solve it? I can't find a location to tighten/adjust the friction in the lift control linkage. Result of this is that fully raised implements slowly drop without any input from me. This is only an issue while the tractor is running. Tractor is an XR4150 ROPS. Any help would be greatly appreciated.
