My mom's JD self p, rear tires turn when off the ground but as soon as you put it down it does not move. Any Ideas.
Thank you

I am thinking that there is possibly a key in the axle that may have come out or broken. I am not certain of this but I have heard of other brands having this issue. What is the model of your unit?

I have a self propelled John Deere JS63C, did the same thing last summer. Replaced the drive belt and tightened up the linkage, and now it'll drag me uphill.
