A walk reel mower has a pivotal rear traction drum that can be selectively disposed in two different mowing positions that allow a single mower to cut grass on golf course greens as well as tee boxes with no degradation in cutting or power performance. The reel cutting unit has a pivotal rear shield to allow the rear shield to be pivotally adjusted to maintain its radial spacing relative to the orbit of the reel at a desired amount as the reel diameter decreases due to wear. The ground speed of the walk reel mower is automatically slowed during turns of the mower by a mechanical cable assembly that links a user operable throttle control and throttle reducing control to a prime mover throttle. Finally, the leverage provided by the mower handle assembly when placed in a lowered position is used by the user to more easily deploy a kickstand.

A disclosed example scissoring mower includes a cutting assembly driven by a gear system. The mower is moved by an operator or motor to cause rotation of wheels. The wheels are coupled to an axle that drives the gear system and thereby the cutting assembly. Accordingly, when the mower is pushed or driven forward, the gear system causes blades of the cutting assembly to move in opposite directions, creating a scissoring action that cuts grass and other vegetation.

A lawnmower uses thin, replaceable blades with a hardened cutting edge and a cross-section defining an airfoil retained in cartridges that are inserted and removed from rotors in a blade assembly at need. The cartridges comprise a blade and rotor interlocking elements affixed to the blade, each rotor interlocking element corresponding to one rotor in the blade assembly. Each rotor and rotor interlocking element includes features that allow the two to be securely engaged so that the rotors may be spun quickly in a mower blade assembly to cut grass.

A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of blades in a blade channel. The blade assembly is covered by a blade assembly guard that is only open underneath at a point where blades in the blade assembly would cut grass during normal operation. A blade assembly access panel in the upper portion of the blade assembly guard allows blades or a blade assembly to be easily replaced.

A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of multi-ductility blades with a maximum thickness of 0.075 inches in a blade channel and in a substantially tangential orientation. The multi-ductility blades include a hardened cutting edge of Rockwell hardness greater than 50 and ductile portion with Rockwell hardness less than 50.

A hydrostatic transmission includes a pump running surface and a motor running surface connected by internal porting formed in a housing member. A valve is disposed in the housing and connects a sump formed by the housing and the internal porting. A trunnion includes a first arm engaged to a swash plate to rotate the swash plate to vary the output of the pump, and a second arm which rotates with the first arm, the second arm having an operative end that is capable of opening the valve to permit a hydraulic connection between the internal porting and the sump through the valve bore when the trunnion is rotated to a predetermined position.

A mowing cylinder cutter and a lawn care tool driven by a built-in outer rotor motor are provided. The cylinder cutter includes an outer rotor motor, blades and a reel. The blades are fixedly connected to the reel through support plates. At least one end of the reel is provided with the outer rotor motor. The outer rotor motor includes a stator assembly and an outer rotor. The stator assembly is connected to a frame through a connecting member, and the outer rotor is fixedly connected to the reel. The lawn care tool includes a working part, a main shaft, a motor shaft and an outer rotor motor. The motor shaft passes through the main shaft. One end of the main shaft is connected to the motor shaft through a bearing assembly. The outer rotor motor is located in the main shaft.
