First Claim
1. An asymmetrical drive vehicle comprising:
- (a) a base structure;
(b) an engine for powering said vehicle;
(c) a first pair of laterally spaced left and right caster-type wheels mounted on a forward end of said base structure;
(d) a second pair of laterally spaced left and right wheels mounted on a rearward end of said base structure;
(e) a third pair of laterally spaced left and right wheels mounted on said rearward end of said base structure and in respective longitudinal alignment with but located behind said second pair of wheels;
(f) first asymmetrical drive means connected between said engine and said second pair of wheels;
(g) mounting means extending between said second and third pairs of laterally spaced left and right wheels;
(h) second drive means operatively associated with said second and third pairs of laterally spaced left and right side wheels and enabling said second pair of wheels to drive said third pair of wheels;
(i) manual control means enabling said second pair of wheels to be driven by said drive means and to rotate either at the same speed and in the same direction or at selected different speeds and directions whereby to provide a means for steering said vehicle; and
