Abstract: Disclosed is an alternator overvoltage protection circuit having a TRIAC and a MOSFET. The TRIAC is electrically connected to the MOSFET and the TRIAC is electrically connected to a magneto. The TRIAC is configured to ground the magneto when triggered by the MOSFET. The MOSFET is electrically connected to an alternator and configured to conduct when the alternator operates in an overvoltage condition. Also disclosed is a method of alternator overvoltage protection for a piece of outdoor power equipment, the method including providing a TRIAC and an alternator rotated by an engine having a magneto, wherein the alternator outputs a voltage when rotated by the engine. The method further includes configuring the TRIAC to ground the magneto when the alternator operates in an overvoltage condition, thereby disabling the magneto, which stops the rotation of the engine and stops the alternator from outputting voltage.

A hydraulic system is operatively connected to the tine assembly and includes a hydraulic pump, a hydraulic motor for use in rotating the tine assembly in first and second directions, a control valve, and hydraulic hose for use in communicating hydraulic fluid between the hydraulic pump, the hydraulic motor, and the control valve. The control valve may be positioned on-the-go into a first position thereby causing the tine assembly to rotate in a first direction and into a second position thereby causing the tine assembly to rotate in a second direction. The tiller assembly may also include a roller assembly that has a roller frame pivotably connected to the tiller body. The roller assembly also includes a roller that is rotatably connected to the roller frame and a spring for use in maintaining the roller against the soil.

Abstract: A hitch assembly includes a base member, an extension arm and an A-frame for supporting any of a plurality of implements. An elevating cylinder is connected to raise and lower the extension arm. Additionally, lateral cylinders are synchronized to move in unison to pivot the hitch assembly laterally side to side. The first respective ports of the lateral cylinders are directly connected together facilitate synchronous movement. A universal joint is connected between the arm and A-frame to coordinate up and down and left and right movement of the hitch assembly.

Abstract: A dynamic drive and brake system is provided. To accelerate the mower in a forward direction, the operator depresses the acceleration pedal, overcoming the biasing force of the acceleration spring. This causes the double idler pulley system to pivot from an inoperative or de-clutched condition to an operative condition. The farther the accelerator pedal is depressed, the more the double idler pulley system pivots and, correspondingly, the more tension is applied to the first belt. The increased tension in the first belt causes the middle pulley member to move in a downward direction and therefore decreases the diameter of the first belt about the double pulley shaft. The movement of the middle pulley member simultaneously increases the diameter of the second belt about the double pulley shaft. This increases the tension in the second belt which tension is absorbed by the idler spring that permits the idler pulley to pivot in a clockwise direction as seen in FIGS. 2-3. The particular diameters of the first and second belts about the double pulley provide increased rotational speed to the transmission input pulley. This increased rotational speed is then transferred to the transmission and on to the back drive axle and back wheels for corresponding acceleration of the mower.

Abstract translation: 提供动态驱动和制动系统。 为了在向前方向上加速割草机，操作者按压加速踏板，克服加速弹簧的偏压力。 这导致双惰轮滑轮系统从不工作或去离合状态转向操作状态。 加速踏板压得越远，双惰轮滑轮系统越枢转，相应地，更多的张力被施加到第一带。 第一带中增加的张力使得中间的皮带轮构件沿向下的方向移动，因此减小了围绕双皮带轮轴的第一带的直径。 中间带轮构件的运动同时增加第二带围绕双皮带轮轴的直径。 这增加了第二带中的张力，该张力被惰轮弹簧所吸收，这允许惰轮沿顺时针方向枢转，如图1和2所示。 2-3。 围绕双皮带轮的第一和第二皮带的特定直径为变速器输入滑轮提供了增加的转速。 然后将这种提高的转速传递到传动装置并传递到后驱动轴和后轮上，以相应加速割草机。

Abstract: A safety switch mechanism for use in connection with a recoil starter using a rope or cable. Such a starter is used on the usual internal combustion engine mounted on a vehicle such as a tractor which carries with it a powered tool such as a grass cutting unit. The mechanism is particularly adapted for safety systems wherein the engine is short-circuited so that the engine can not be started by pulling the rope or cable unless both the clutch of the tractor and the clutch of the powered tool are disengaged. This safety switch mechanism has a unique construction enabling it to be locked in open position so that the switch mechanism is not inadvertently opened by vibration or other means after the engine is started and the tractor and powered tool are being used. This is an abstract only of the specific illustration of the invention given by way of example, and is not to be used in the interpretation of the claims nor as a limitation on the scope of the invention.
