Abstract
A steering system for a vehicle having left and right endless tracks, left and right sprocket wheels, a motor and a hydraulic pump includes left and right hydraulic motors mounted to a respective one of the left and right sprocket wheels, a hydraulic circuit connecting the fluid outlet of each hydraulic motor to the fluid inlet of the other hydraulic motor, and a steering mechanism for receiving hydraulic pressure from the hydraulic pump and selectively distributing it to the first and second hydraulic motors. The steering mechanism is in fluid communication with the fluid inlets of the left and right hydraulic motors to provide hydraulic pressure in response to first and second steering inputs from a user. An attachment kit includes the steering system.
