摘要： A sprayer has a tank for holding a spray solution that is applied to a ground or turf surface. The sprayer includes an agitation system having a plurality of agitation nozzles that extend into the tank that are accessible from outside the tank and can be removed and replaced without using tools. The sprayer may include a rinse system carried onboard the sprayer which is segregated from the spray and agitation systems to avoid contaminating the rinse liquid prior to the time the rinse liquid is sprayed into the tank through rinse nozzles. The rinse nozzles include upwardly and downwardly directed nozzle ports and a bottom spinner for thoroughly cleaning all interior surfaces of the tank. The sprayer may also include a chemical eductor mounted on the side of the tank, whose weight is counterbalanced by springs, and which easily pivots between lower and upper positions on the tank.

摘要： The present invention relates to an improved mechanism (100) for attaching a ground-engaging surface maintenance implement, preferably a front-mounted rotary sweeper (300), to a traction vehicle (200). The mechanism includes a four-bar linkage (102) to "yaw" the implement from an initial position, where the sweeper brush axis is generally perpendicular to the longitudinal axis of the traction vehicle (200), to a first or second position, characterized by the brush axis assuming an angled (i.e., non-perpendicular) orientation, the first and second positions being equal but opposite to one another. The mechanism further includes a central pivot (104) which permits the implement to "roll" or rotate preferably about a horizontal axis perpendicular to the brush axis such that the sweeper (300) can maintain ground contact across its lateral width when traversing laterally uneven terrain. The preferred mechanism also includes a force-producing device (148), selectively activated by the operator, to translate the implement from its initial position to the first or second position or anywhere in-between. Finally, the preferred embodiment of the present invention includes ground-contacting caster-wheels (318) to support or partially support the weight of the sweeper and therefore relieve the weight borne by the sweeper brushes (304).
摘要翻译： 本发明涉及一种用于将地面接合表面维护工具（优选地是前安装的旋转清扫器（300））附接到牵引车辆（200）的改进机构（100）。 该机构包括一个四杆连杆机构（102），用于将起重机器从初始位置“摆动”，其中清扫器刷轴线大致垂直于牵引车辆（200）的纵向轴线，到达第一或第二位置，其特征在于 通过刷轴线呈现成角度（即非垂直）取向，第一和第二位置彼此相等但相反。 该机构还包括一个中心枢轴（104），其允许工具优选围绕垂直于刷轴线的水平轴线“滚动”或旋转，使得当跨越横向不平坦的地形时，清扫机（300）可以在其横向宽度上保持接地接触 。 优选的机构还包括由操作者选择性地启动的力产生装置（148），以将工具从其初始位置转换到第一或第二位置或其间的任何位置。 最后，本发明的优选实施例包括地面接触脚轮（318），以支撑或部分地支撑清扫机的重量，并因此减轻了由清扫机刷（304）承载的重量。

摘要： An evaluation tool for viewing local and remote irregularities in a turf surface. The tool includes a body structure having first and second turf engaging surfaces for supporting the body structure upon the turf surface in first and second inspection orientations. The tool further includes a reflector element to provide a view of a local turf segment to a user viewing from above when the body is in the first inspection orientation and a view of a remote turf segment when in the second inspection orientation. Indicia may be provided upon the tool for indicating vertical distances.

摘要： A mower, such as a riding mower, has two side cutting units and a front cutting unit operatively connected to a traction frame. Each side cutting unit can pivot about a substantially vertical axis relative to the traction frame when impact shocks occur on the outer sides of the cutting units. A shock absorber cushions and absorbs such impact shocks, and resists the pivoting motion of the side cutting units, in a bi-directional fashion to be effective during forward or reverse motion of the traction frame.

摘要： A leak detector apparatus 10 is disclosed which measures changes in fluid level in a tube 54 substantially located within a reservoir 29 of hydraulic fluid. The tube 54 has a first end which is open to the atmosphere and a second end which is submerged in the hydraulic fluid. The reservoir 29 is selectively sealed, therefore changes in the volume of the fluid within the reservoir 29 cause the fluid level within the tube 54 to change in accordance with the principles of a manometer. A measuring device is utilized to determine the level of the fluid within the tube 54, wherein the measurement device can include a float 22 having a magnet 23 located thereon interacting with a linear array of Hall effect sensors 24. A controllable venting valve 28 is provided through the reservoir 29 to equalize the pressure within the tank with the external ambient pressure. The opening and closing of the venting valve 28 is controlled by an electronic controller device 30 that uses float position and hydraulic fluid temperature as inputs, among others. Accordingly, the float position can be reset within the tube to extend the range, thereby creating a virtual column.
