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.

摘要： An automatic shotgun choke is provided which is attached to the muzzle of a shotgun barrel and can be adjusted manually by a device mounted within and extending from upper portion of the choke so as to selectively produce a choked and unchoked muzzle. In a modification gas pressure from a fired shell turns fan blades within the choke to operate a choking action upon a charge as it leaves the muzzle.

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.
