摘要： A harvester which uses a rotary style cutter bed has a series of rotary cutters extending across the path of travel of the machine and rotatable about individual upright axes. Part of the cutter bed is a flat gear case containing a train of intermeshed spur gears that serve to distribute power between the cutters above the gear train. Each end of the gear case has a hollow, gearless extension welded thereto which supports at least one additional outboard cutter that receives its driving power exteriorally of the gear case. One embodiment uses a mechanical drive to bring power to the upright shaft of the cutter having the first spur gear so that the cutters with gears receive all their power from the driven cutter. The outboard cutters not having gears are driven by exterior, over-the-top drive mechanism coupled with the shafts of the first and last geared cutters, such drive mechanism alternatively taking the form of timing belts with timing sheaves, chains and sprockets, gear box and universal joint couplings or a spur gear train. As an alternative to a mechanical drive, the cutter bar may utilize a pair of hydraulic motors coupled with the shafts of the first and last cutters having gears. All of the gears in the gear case remain positively enmeshed with one another in the gear train, so that the two hydraulic motors share the total load of driving the cutter bed and such loading is balanced between the two hydraulic motors, prolonging the useful life of the gears and other drive components. The added on, outboard cutters are driven over the top using timing belts, timing sheaves, universal couplings or a spur gear train.

摘要： A gear box for a grass mowing machine with a generally horizontal shaft extending from the engine and/or transmission, and a rotary cutting blade with a generally vertical shaft. The gear box has a top surface and a bottom surface, the gear box enclosing the first end of the generally horizontal shaft and the first end of the generally vertical shaft. The generally vertical shaft extends through the bottom surface of the gear box. The gear box houses a pair of spiral bevel gears to change the transmitting direction from the generally horizontal shaft to the generally vertical shaft. The measurement from the generally horizontal shaft to the bottom surface of the gear box is greater than the measurement from the generally horizontal shaft to the top surface of the gear box.

摘要： An axle driving unit having a housing (21,22) for supporting a first axle (17) for mounting thereon a first driving wheel (3L), and a longer second axle (18) for mounting thereon a second driving wheel (3R). The axle driving unit is eccentrically mounted on a body frame (1) in proximity to the first driving wheel (3L). A speed change transmission (T) is disposed in an enlarged region of the housing that extends substantially perpendicularly with respect to the axles (17,18). The axle driving unit can thus be easily disposed to the side of a chute (6) of a rear-discharge type lawn tractor.

摘要： A lawn mower is powered by two vertical shaft engines mounted on the chassis and equispaced about the longitudinal axis of the chassis. A vertical drive shaft is rotatably mounted on the longitudinal axis of the chassis. The outputs of both vertical shaft engines are transmitted through belts and pulleys to the vertical drive shaft, which is rotated by the combined outputs of both vertical shaft engines. Other pulleys are secured to the vertical drive shaft and connected through belting to pulleys which rotate grass-cutting blades and to pulleys which operate motors turning the driving wheels to propel the lawn mower.

摘要： In a garden appliance provided with a traveling drive, the tools, for example a mowing tool, are driven by a motor which is also coupled to the drive wheels. Connected between the motor and drive wheels is a gear which reduces the speed of the drive wheels with increasing output requirement or increasing torque, and vice versa. As a result, it is, for example, effected that in the case of a high resistance to mowing the advance of the mower is less than in the case of a low resistance to mowing. A V-belt pulley gear with variable radii can be used as the gear, the axial adjustment of the V-belt pulley halves being effected as a function of the load torque. This setting can be performed against the action of return springs via helical threads which can be constructed, for example, in the form of a ball self-closure.
摘要翻译：在具有行驶驱动器的花园设备中，诸如割草工具的工具由也连接到驱动轮的马达驱动。连接在电动机和驱动轮之间的齿轮是减小驱动轮的速度以增加输出要求或增加转矩的齿轮，反之亦然。结果，例如，在割草的高抗性的情况下，割草机的推进的时间要小于在割草时的低阻力的情况。可以使用具有可变半径的V型皮带轮齿轮作为齿轮，V型皮带轮半部的轴向调节作为负载转矩的函数来实现。这种设置可以通过螺旋螺纹来克服复位弹簧的作用，例如可以以球自闭的形式构造。
