Abstract
A rear suspension device for a ride-on mower includes a pivoting assembly coupled to the frame of the ride-on mower by a torsion bar which has a transversely extending back portion that can be trapped between projections on the rear portion of the frame of the mower and a front surface of the pivoting assembly. Portions of the torsion bar extend substantially parallel to a longitudinal axis of the ride-on mower and have ends that extend through apertures in torsion bar brackets that are coupled to the pivoting assembly. The suspension device is capable of transferring weight from one portion of the ride-on mower to another portion of the ride-on mower, thereby enhancing stability.
