摘要： A riding lawnmower outrigger (1) having a hollow outer tube (5) secured to a riding lawnmower (2), a telescoping inner tube (6) which locks within the outer tube (5), a vertical tube (11) connected to the inner tube (6), an outrigger wheel housing (16) secured to the vertical tube (11) and a wheel (7) secured within the outrigger wheel housing (16). When utilizing the riding lawnmower outrigger (1) on a ground surface (32) having a slope (31), the riding lawnmower (2) will not tip-over or rollover because the riding lawnmower outrigger (1) acts as a supporting arm to balance the riding lawnmower (2) and prevent tip-over thereof.

摘要： An enabling tractor arranged for small crop cultivation, even by those with some manual handicaps, has four wheels with two powered rear wheels and caster type steering controlled by hand an foot levers that move in unison and in sympathy with the steering movement of the front wheels. The chassis has an open center for direct access of the operator to carried tilling apparatus while the tractor continues forward under steering control. Power delivery to the drive wheels is optionally controlled by a clutch arrangement that minimizes maintenance problems.

摘要： A simple operator presence override circuit is connected between available terminals on a PTO switch and a brake switch, and to the seat relay of the operator presence system. The override circuit permits continued operation of the engine under certain restricted conditions when the operator leaves the vehicle seat. A blocking diode connects one side of the seat relay to ground via the brake switch and one set of terminals on the PTO switch. With the PTO switch in the off condition and the vehicle braking system activated so the brake switch is closed, the seat relay remains activated to prevent operation of the ignition grounding circuit that otherwise would shut the engine down when the operator leaves his seat. Switching the PTO switch on or deactivating the braking system without an operator on the seat will automatically open the seat relay so that the engine is killed.
摘要翻译：在PTO开关和制动开关的可用端子与操作员存在系统的座椅继电器之间连接简单的操作者存在覆盖电路。当操作员离开车辆座椅时，超驰电路允许发动机在某些限制条件下继续运行。阻塞二极管通过制动开关和PTO开关上的一组端子将座椅继电器的一侧连接到地。当PTO开关处于关闭状态并且车辆制动系统被激活，使得制动开关闭合时，座椅继电器保持启动，以防止点火接地电路的操作，否则当操作者离开座椅时将关闭发动机。打开PTO开关或停止制动系统，而不需要座椅上的操作员将自动打开座椅继电器，以使发动机死亡。
