I did the same on ice. Tried to cross 25 ft. of rutted, melting ice in my lane way after returning from getting a new rear tire.
I really thought I could just get it rolling, pull in the clutch and coast over it,...WRONG!
Fortunately, I didn't have a broken arm. So after realizing that the rear tire was sliding to the right and trying to muscle it, to keep it up,...I gently as possible lowered it to the ground on it's left side, to a NORMAL, gravity induced, resting position. The ice was clean so no scratches but it snapped off the shift pin.
A single tracker by definition is unstable,..The preferred state of equilibrium must be constantly maintained by artificial means.
Ya,...I'm a dumb-ass to.
