摘要： A flexible rotary mower deck lift system includes a center deck having a first end and a second end, and a wing deck pivotably attached to each of the first and second ends. A linear actuator may be actuated to raise and hold each wing deck at a position that is parallel to the center deck, and a lift cylinder may be actuated to raise the center deck and the wing decks together to an intermediate position above a ground surface wherein the center deck and the wing decks are out of contact with the ground surface.

摘要： An vehicle with defined power on demand including a control system configured to provide to an operator a plurality of selectable features each have selectable options. The defined power on demand utilizes unrealized engine power which is limited by an engine control system for reasons of fuel savings and cost effectiveness. The selectable features include power take off (PTO), mechanical front wheel drive (MFD), front hitch, and rear hitch. Selectable options include a plurality of defined amounts of power delivered by a vehicle engine over a period of time with respect to a selected feature. The defined amount of power is greater than the power at which the engine typically operates as limited by the engine control system. The greater power is provided over a period of time to complete each of the selectable features.
摘要翻译： 具有按需定义的功率的车辆，包括被配置为向操作者提供多个可选择特征的控制系统，每个都具有可选择的选项。 定义的电力需求利用由发动机控制系统限制的未实现的发动机功率，因为节省了燃料并且具有成本效益。 可选功能包括动力输出（PTO），机械前轮驱动（MFD），前悬挂和后悬挂。 可选择的选项包括在相对于所选择的特征的一段时间内由车辆发动机递送的多个定义的功率量。 定义的功率量大于发动机通常由发动机控制系统限制的功率。 在一段时间内提供更大的功率以完成每个可选择的特征。
