Abstract
A transmission control mechanism for a vehicle having a dual hydrostatic transmission vehicle drive system having a first and second lever mounted to respective displacement control rods of transmission pump units. A cross member communicates with the levers via connecting rods. A steering column is mounted to the cross member. The steering column is mounted in the vehicle such that it can experience simultaneous rotational and pivotal motion. Pivoting of the steering column causes the pump units to displace with a constant relative displacement, and rotation of the steering column causes the pumps to displace with a differential relative displacement.
