I'm thinking of two ideas:
1) gear welded around the original steering shaft, hidden under the body panels somewhere, driven by a worm gear on a CIM motor. Controlled by 2 buttons, left and right.
2) More complex, remove original transaxle from rear, run tank drive thru two transmissions, power wheels style, remove front steering altogether, install front wheels much like those on zero-turn lawn mowers. Same concept actually, just electrically powered instead of hydraulically.
