Abstract: A vehicle combining the attributes of a tractor and a utility vehicle includes a three point linkage and other locations to which a plurality of attachments for performing grooming or working operations on a ground or turf surface may be couple. The vehicle includes a front mounted engine, a mid-mounted operator compartment and a rear mounted bed or box. A PTO shaft and/or a hydraulic power system of the vehicle power attachments that require power. A control system and a visual display and data entry device linked thereto are provided for allowing an authorized person to setup, store and thereafter use an operational profile for each attachment that is to be coupled to the vehicle. In a rate dependent attachment, the control system maintains the ground speed and the attachment implement in a fixed ratio. A down/up control is used to signal the start and end of an operational sequence to the control system.

Abstract: This invention relates to a mower and a tracked implement tohat convert from one to the other by coupling a mower unit or a tracked unit to a common drive unit. The drive unit is thus used in both products to provide cost savings in the purchase of the equipment. In the tracked unit, a cab for enclosing the operator's station is part of the tracked unit and gets mounted to the drive unit when the tracked unit is coupled to the drive' unit. A pair of idlers rotate on pivot axes that are fixed relative to a pivotal idler support that carries the idlers. The pivot point for the idler support is chosen to prevent track elongation when the tracked unit climbs obstructions such as a curb. In the mower unit, a relatively heavy cutting deck is used and spring biased weight' transfer arms transfer some of the deck weight to the mower frame .

Abstract translation: 本发明涉及通过将割草机单元或跟踪单元耦合到公共驱动单元而从一个转换到另一个的割草机和履带式工具。 因此，驱动单元用于两种产品，以便在购买设备时节省成本。 在跟踪单元中，用于封闭操作员站的驾驶室是被跟踪单元的一部分，并且当被跟踪单元联接到驱动单元时被安装到驱动单元。 一对惰轮在枢转轴线上旋转，该轴线相对于承载惰轮的枢转惰轮支架固定。 当追踪单元爬上诸如路缘石等障碍物时，选择惰轮支撑的枢轴点以防止轨道伸长。 在割草机单元中，使用相对较重的切割板，弹簧偏置重量的转移臂将一些甲板重量转移到割草机框架上。
