Abstract: The present invention provides mechanisms for tilting the seat of a tractor or similar vehicle. In some embodiments, a cam shaft provides dual opposing cams positioned under the seat, so that when the cam shaft is rotated, the cams tilt the seat to one side or another. A switch connects an electric motor to a power supply, such as the battery of the vehicle, so the vehicle's operator can activate the motor to rotate the cam shaft and thereby tilt the seat to a desired angle. When the vehicle traverses a slope and tilts to one side, the inventive mechanisms are useful to return the seat to a level position relative to the horizon, thereby allowing the operator to better maintain control of the vehicle and keep his or her back straight. This provides potentially greater safety and comfort for the operator.
