    x744 outside rear tire tearing up grass

    I'm trying to figure out if I have a problem or if what I'm seeing is normal. I have a new to me this summer x744 and when I turn tightish(think 14" tree) the outside rear wheel will rip up the grass. In thick grass it isn't all that noticeable, but in the thin areas it looks like crop circles around my trees. At first I thought I must have been driving too fast, but it doesn't matter, it happens at any speed. Any just in case you're wondering, no I'm not stepping on the diff lock button, LOL. So, is this a normal issue or is my diff not working right?

    Maybe try to do some tight turns on a hard surface and see if it hops around the turn. Even though you’re not pressing the diff lock, it still could be engaged. If the brake linkage isn’t set properly, that will engage the diff lock too...since there is only one brake for both wheels, the diff lock is engaged first when the brake is applied.

    It does sound like the differential lock is engaged. As stated above, do some circles on pavement and if either wheel is "dragging" make sure the DifLock pedal linkage is free. If stuck, try backing up with no pressure on the lock pedal. This "usually" will allow it to disengage.

    IF it won't disengage something is hanging the locker up in the transmission case or along the linkage. (Broken return spring, etc.)

    Keep us posted!

    My new x739 has torn the heck out of my lawn. Seems to be my front (AWD) causing the problem. I'd love to know why. I certainly don't race around either

    If it was a diff lock issue, wouldn't it be the inside tire tearing up lawn, not the outside?

    Please see my photos in X739 jerkiness thread. Are the pics anything like your lawn?

    Mine is mainly in turns but I do leave a heavy tire footprint (turns and straights) and I need to make sure I alter my mowing pattern. Yours is doing that per pass or over a period of time?

    Those photos are the maiden cut! There is no PDI (pre-delivery inspection) evidenced as the tires were not properly inflated and the hydraulic fluid was not registering on the stick; 0.0 on the hour meter........ever buy a new car with 0.0 on the odometer?
