摘要： An electric drive mower includes an electric traction drive as well as electric drive to the cutting units carried on the mower. A hybrid electric drive system supplies electric power to these motors. The electric drive system includes a genset (an internal combustion engine driving an electrical power generating device such as an alternator) and a battery pack which supply the electric power to the electric motors either individually or jointly. A switch may be provided to permit all battery operation of the mower. A steering system having a non-powered pump is used to effect steering of the steerable wheel(s) of the mower to avoid having a heated oil damage the turf in the event of a leak. A crankshaft driven by a single electric drive motor is linked to all the cutting units through various crankarm and connecting rod linkages to lift and lower the cutting units in a timed manner.

摘要： A walk aerator comprises a frame supported by a plurality of ground engaging wheels, the frame carrying a coring head having a plurality of side-by-side tine assemblies. The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft driven by a single pulley, the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced. Integral core deflectors are used on the drive arms. A connecting link extending across each drive arm is used to connect each drive arm to the coring head to decrease the coring head depth.

摘要： This invention relates to a hybrid lawn mower powered by a fuel cell and an electrical storage system, both of which supply electric power to the drive wheels and cutting units of the mower. The electrical storage system comprises an ultracapacitor pack or a battery pack. The electric motor driving each cutting unit comprises a brushless motor having an integrated gear reduction stage. In addition, the motor includes an integrated electronics housing in which the electronics for controlling and powering the motor are packaged. The cutting units are lifted out of engagement with the ground by a lift and lower system comprising an electric/hydraulic actuator that is driven only during lifting of the cutting units. The cutting units are lowered by releasing fluid pressure in the lift and lower system and permitting the force of gravity to lower the cutting units.

摘要： A walk reel mower has a front mounted reel cutting unit and a rear handle. The operator pushes the handle towards the ground to lift the reel cutting unit off the ground prior to turning the walk reel mower around. When this occurs, the manner in which the reel cutting unit is supported in conjunction with the influence of gravity causes the reel cutting unit to pitch rearwardly relative to the frame of the walk reel mower. This change of orientation is used to close a switch which, in turn, initiates an automatic slow down of the mower to ease the task of turning the mower around. When a turn is completed and the cutting unit is dropped back down into engagement with the ground, the slow down is terminated and the ground speed resumes at whatever predetermined ground speed was previously selected by the operator.
