Abstract: A suspension system for use with a work vehicle. The suspension system may include a suspension tower to which one or more shock absorbers may attach. The tower may permit the shock absorbers to attach at multiple locations, effectively allowing the angular orientation of the shock absorbers, and thus a suspension characteristic of the suspension system, to be altered. The tower may be movable relative to the vehicle, e.g., for crating/shipping.

Abstract: An assist handle for assisting an operator with climbing on to, or off of, a ground maintenance vehicle such as a mower, and a ground maintenance vehicle incorporating the same. The assist handle includes, in one embodiment, a grip portion movable between a deployed position, wherein the grip portion is positioned at a deployed elevation configured to assist the operator with ingress to, or egress from, a platform such as a seat; and a stowed position, wherein the grip portion is positioned at a stowed elevation lower than the deployed elevation.

Abstract: Embodiments of the present invention relate to powered vehicles (e.g., lawn mowers) and, more particularly, to a control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity profile control system having an adjustment member that permits altering a ratio between control lever movement and velocity of an associated drive member or wheel. Thus, the system may alter a maximum potential velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position without varying an output level of the power source.
Abstract translation: 本发明的实施例涉及动力车辆（例如，割草机），更具体地，涉及一种用于这种车辆的控制系统。 在一个实施例中，车辆包括诸如内燃机的动力源和可在空档位置和最大速度位置之间递增移动的一个或多个驱动控制杆。 该系统还可以包括速度分布控制系统，其具有允许改变控制杆运动与相关联的驱动构件或车轮的速度之间的比率的调节构件。 因此，当驱动控制杆位于最大速度位置时，系统可以改变车辆的最大潜在速度，而不改变动力源的输出水平。

Abstract: Suspension systems and grounds maintenance vehicles incorporating the same are disclosed. The suspension system may include biasing elements or springs that may be adjusted to vary the preload and thus change the spring and dampening characteristics of the suspension system. In some embodiments, the system may include an adjustment mechanism that permits simultaneous adjustment of two springs via a single action. In other embodiments, features adapted to assist an operator with mounting/dismounting the vehicle are disclosed.
