Been having constant issues while pulling a MoCo. All hydraulic functions on the remotes will cease. But then other times just the far right black lever will work. Sometimes you either have to turn the tractor off, or just keep wiggling levers for a while until all three start working again. Turning the engine off doesn’t always work.
Don’t know if it’s related, but the power steering sometimes quits as well. I’m not convinced that’s directly connected with the rear hydraulic issues because it never shows up at the same time.
