Need help. I have a D6D 4X4844 and parked it last fall with no problems. Went to use it to remove some drifted snow. All it will do is make right turns. Thought I might have had some ice in the system and waited till now to try again. Still only will make right turns. Seems like the brake on the right side is not releaseing. If I try forward sometimes it will travel a few feet then stop. If i pull the left steering clutch it will make a right turn. In reverse it does the same thing. I tried applying both brakes and now it won,t do anything in forward or reverse! Sure hope someone has an idea. Oh by the way it has a cab on it and I have no way to remove it. All the linkage is working as well.

Thanks, Corks

Might have something jamming up your steering valve. Like Metal from bevelgear bearing failure. That machine should have steering and brakes both on the lever so valve problem could do that.
Check the filter and magnetic screen for any contamination and come on back.
