<p>Embodiments of the present invention provide a tracking-adjustment system (108) for adjusting the tracking of a walk-behind hydraulically driven mower (10) or other vehicle. In the event the mower (10) fails to properly track and begins veering right or left during operation, the tracking-adjustment system (108) can be used to make tracking adjustments and thereby restore proper, straight-line tracking. In some embodiments, the tracking-adjustment system (108) provides a single tracking knob (120) that an operator can rotate to simultaneously adjust the output of right and left hydraulic pumps (32, 34) and thereby adjust the rate of hydraulic fluid pro-vided to respective right and left hydraulic motors (36, 38) that drive respective right and left drive wheels (12, 14).</p> |
