    Stuck diff lock

    Anything I can do for a stuck diff lock? Or does it require a trip to the dealer? It just started doing it yesterday. It is not in 4x4.

    Is your brake linkage free? Check for debris in the linkage and make sure it moves freely.

    Seems to be a common problem, though not really a problem with the one series. The diff-lock is designed to engage when the brakes are applied because there is only one brake and if the diff was not locked one wheel could spin. Like Dieselshadow said check the linkage. If all looks good then it should be just a minor adjustment. I know some one series owners have said it is easier to apply some brake to lock the diff when needed than to use the diff-lock itself.

    The linkage feels like it's operating freely but I will check for obstruction.

    I checked for any obvious obstructions and did not find anything. However, what I did find when following the diff lock foot lever to the diff, is that it is not connected to anything on the diff and it looks like the bracket on the diff may be stuck in the locked position. When moving the foot lever, it does not move anything on that bracket. Shouldn't it be connected?

    Edit: Here is a video of the foot lever working:

    I just checked mine and from what I can tell it looks like yours is stuck internally or the brake pedal is down or needs adjustment.
    Now on mine, with the brake pushed down the diff pedal linkage looks just like your video, but if its the left side diff pedal its got to be stuck internally or like i said the linkage in the brake pedal it screwed up.

    I'm going to risk pointing out the obvious. If the diff is under pressure, it won't disengage. I usually reverse momentarily when I get to flat ground to make sure the diff lock has disengaged.

    Seems there was some tiny gravel/rocks jammed up on the brake side of the diff in and around the spring. Once I got that free I was able to engage/disengage the diff lock by hand. All looks to be ok now. Thanks for the help.

    I noticed the first time I used mine in December that it picks up gravel in my drive way while pushing snow and throws small pieces up there. Havent had any issues /w it so i didnt think of that directly. If it causes more problems maybe wrap a cut up tire or bicycle inner tube around it and zip tie it down.

    Had an issue with mine where the linkage turns and gets cocked in the ear on the diff itself and jams
    Service manager has a call in to deere to see about a fix but they temporarily stuck a washer on it...see if that works
    Also from what I can tell by just moving forward, the differential automatically tries to lock.
    The lever gets pushed down and allows the ear to flip down and lock
    The lever actually just holds it out of the lock position
