20110254241 | CASTER WHEEL SUSPENSION FOR A ZERO-TURN MOWER - A zero-turn mower comprising a zero-turn mower frame, a front axle coupled to the zero-turn mower frame, first and second caster wheel assemblies, and first and second front shock assemblies. The front shock assemblies rotatably and telescopically couple the caster wheel assemblies to the front axle, thereby providing vertical shock absorption. The front axle may be a floating axle that is pivotably coupled to the mower frame and/or the shock assemblies may define an internal spring-receiving chamber that is substantially isolated from the external environment. Such a zero-turn mower may provide a smoother ride and may require less maintenance and repair than conventional zero-turn mowers. | 10-20-2011 |

The steering and braking systems may be configured such that when the tractor mower is steered in a first direction the front wheels are turned to the right and a braking force is applied on the right rear wheel. Alternatively, when the tractor mower is steered in a second direction the front wheels are turned to the left and a braking force is applied on the left rear wheel. | 10-09-2014 |
