I have an X1140 and all of the sudden I have lost power. Fluids are all the super udt and changed regular. All are at proper levels when checked. Wheels turn with acceleration when off the ground. Barely moves when on the ground. Same in forward and reverse and 2 wheel and 4 wheel drive. I dont know alot about how the hydrostatic system works. Any thoughts or direction is appreciated.

You have checked the oil level in the hydraulic oil tank beneath the front passenger seat, correct? That is where the HST gets its oil supply from.

Park on level ground, release the park brake, and try to roll the machine one way or the other by hand. It is possible that the brake shaft passing through the case may be hanging up, not letting the brakes fully release.
