摘要： A seat mechanism including a switch flap mechanism formed integrally with a first seat pan member made of a plastic material. When an operator sits on the first seat pan member, the switch flap deflects downwardly under the weight of the operator. The switch flap deflects downwardly to engage a plunger switch mounted with a second seat pan member. When the plunger switch is depressed the vehicle components are shifted to an operative mode. An operator presence function is thereby served.

摘要： A rack and pinion steering mechanism for use with a vehicle having a frame, an operator station and steerable ground engaging wheels. The mechanism provides a steering wheel, a steering column, a pinion gear coupled with the steering column, and a rack gear plate member having an opening for receiving the pinion gear. The opening has a laterally extending toothed portion engagable with the pinion gear, and has laterally outward end portions engagable with the pinion gear for limiting the lateral shifting of the rack gear plate member. A support plate is coupled with the frame and is abuttable with the rack gear plate member for securing the rack gear plate member between the support plate and frame for maintaining the rack gear teeth in operative engagement with the pinion gear.

摘要： A lawn and garden tractor includes an inclined steering input shaft and a vertical steering output shaft which are both journalled for oscillation in a support plate and which converge downwardly. Respectively axially shiftably keyed or splined on the input and output shafts at respective desired working positions just below the support plate are a straight bevel gear and a gear sector. The gear and gear sector are biased to their desired working positions by a pair of coil springs.

摘要： A mechanism usable with a vehicle having a compartment for carrying a battery. The mechanism includes a cover shiftable in a first direction for generally enclosing the compartment. The cover includes latching member for securing the cover in a compartment enclosing position, and also includes an abutment structure for abutting the battery as the cover shifts in the first direction to enclose the compartment. The cover can be deflected further in the first direction to become latched in the compartment enclosing position with the battery in abutment with the abutment member. The latched and deflected cover acts to resiliently bias and press the battery into secure fixed position within the compartment.

摘要： A mower deck within which a blade coupled with a vertical shaft rotates for cutting vegetation. The deck includes a generally horizontal central portion, and side walls downwardly extending from the central portion. The central portion and side walls form a compartment within which the blade rotates to cut vegetation. A vertically extending and generally cylindrical portion is formed integral with the central portion for operatively supporting the vertical shaft for rotation during mowing operation. Two bearings are positioned within the cylindrical portion for rotatably supporting the vertical shaft. A radially inwardly extending portion is formed within the cylindrical portion and is positioned between the bearings for vertically locating the bearings within the cylinder. The inwardly extending portion is formed integral with the cylindrical portion. The radially inwardly extending portion includes a plurality of vertically extending support ribs for vertically locating the bearings within the cylinder.

摘要： A unitized engine transaxle combination preferably having a variable speed transmission such as a hydrostatic or continuous variable transmission for utilization in a work vehicle, the combination including a specific arrangement of components parts inside the transaxle housing and the connection of the engine thereto to provide the engine transaxle combination unit. In the preferred embodiment, a hydrostatic pump is connected to the engine and the hydrostatic motor is positioned inside the transaxle housing on the same side thereof in relation to the left or right side of the combination. In close proximity to the hydrostatic motor, a speed reduction unit is also housed inside the transaxle housing. The other end of the transaxle housing houses a differential unit. The hydrostatic pump is driven by a cam gear mechanism which is contained within the engine housing and interconnects with the engine crankshaft and the hydrostatic pump input shaft so that the hydrostatic pump is driven thereby. Preferably, the engine and the transaxle are interconnected and include at least a partially common housing. The engine is positioned as close to the ground and as close to the transaxle as possible in order to lower the vehicle's center of gravity while still providing sufficient clearance between the output end of the engine crankshaft and the ground. A single belt is utilized to drive a working implement operatively connected to the vehicle from the engine output shaft to an implement input shaft. This single belt passes through a space created in the transaxle by the arrangement of the component parts as described above. The space created is sufficient to allow the vehicle to operate the implement with a maximum vertical float which occasionally, but not for extended periods exceeds the recommended manufacturer's belt misalignment angle without interference between the belt and the bottom of the transaxle housing.

摘要： The brake-clutch interlock includes a latch having a groove sized to receive a plurality of pins co-linerally aligned within the groove. The groove is shaped such that the latch cannot receive nor release either pin singularly. One of the pins is in linked communication with the vehicle clutch actuating means. The other pin is in linked communication with the vehicle parking brake actuating means. When both pins are properly aligned to be locked in place by the latch, the vehicle clutch is disengaged and the vehicle parking brake is engaged. The latch restrains the pins in such a manner that neither pin can be singularly released.

摘要： An improved drive structure is provided for use between a lawn and garden type vehicle and a vertically adjustable belt driven, belly-mounted implement such as a rotary mower. The structure is usable with a standard length engine crankshaft which is mountable to project below the vehicle chassis and power the belt driven mower. It includes a stub shaft extension that is adapted to carry an electric clutch as well as a pulley for driving a belt entrained around the mower spindle pulleys. The extension permits positive power transmission to the drive pulley and also allows for it to be mounted substantially horizontal with the implement pulleys as they are shifted vertically in response to height of cut adjustments and/or variation in terrain. The extension further eliminates the need for jacksheave power relay arrangements commonly used to reduce the angles of drive belt entry and exit into and out of drive and driven pulleys.
摘要翻译： 提供了一种改进的驱动结构，用于草坪和花园型车辆之间以及垂直可调节带驱动的腹部安装的工具，例如旋转割草机。 该结构可用于标准长度的发动机曲轴，其可安装在车辆底盘下方并对皮带驱动的割草机供电。 它包括短轴延伸部，其适于承载电动离合器以及用于驱动夹在割草机主轴滑轮周围的带的皮带轮。 该延伸件允许正向动力传递到驱动皮带轮，并且还允许其随着工具滑轮基本上水平地安装，因为它们相应于切割调整的高度和/或地形的变化而垂直移动。 该扩展进一步消除了对通常用于减小驱动带进入和离开驱动和从动滑轮的角度的千斤顶功率继电器布置的需要。
