A drive system includes a first transmission, a second transmission and at least one flexible driving member. The first transmission is operably coupled to a first set of wheels to provide drive power to the first set of wheels responsive to engagement of the first transmission. The second transmission is operably coupled to a second set of wheels to provide drive power to the second set of wheels responsive to engagement of the second transmission. The at least one flexible driving member is operably coupled to a remote actuator and a drive shaft of the walk-behind outdoor power equipment device. The at least one flexible member selectively engages one of the first transmission or the second transmission to switch a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode via the remote actuator.

In a walk behind mower (10) including a clutch (23) provided in a power transmission path between an electric motor (35) and driven wheels (13), a clutch actuating mechanism (24) interposed between the electric motor and the clutch for selectively engaging the clutch, and a control unit (140) for selectively supplying electric power from a power source to the electric motor according to a command from an operation switch (30), the clutch actuating mechanism includes a cam mechanism for engaging the clutch by using a force transmitted to an input end (23a) of the clutch in the power transmission path when the electric motor is being driven in a normal rotational direction, and the control unit is configured to drive the electric motor in a reverse rotational direction for a prescribed period of time before stopping supplying electric power to the electric motor when a command to stop supplying electric power to the electric motor is received from the operation switch.

A walk power mower having a cutting deck supported upon the ground by front and rear wheels. The mower includes a biased handle that permits the handle to be pivotally displaced downwardly, against an upward bias force, during operation. The bias force may be provided by a resilient member that compresses as the handle is displaced downwardly. The compression of the resilient member allows downward movement of the handle without initially producing corresponding upward movement of the front wheels of the mower during rearward pulling of the handle.

A lawn mower (10) may include a blade housing (20), an engine (30), a mobility assembly (310); and a drive system (300). The engine (30) may be operably coupled to the blade housing (20) and configured to selectively rotate a drive shaft (130). The mobility assembly (310) may include a first set of wheels (40, 42) and be selectively operably coupled to the engine (30) to provide mobility of the lawn mower responsive at least in part to operation of the engine (30). The drive system (300) may include a first transmission (110, 120), a flexible driving member (100), a disengagement assembly (116), and a remote actuator. The a disengagement assembly (116) may include a latching lever (125), where the latching lever (125) is configured to switch the first transmission (110, 120) between a disengaged mode and an engaged mode, and where the latching lever (125) is configured to move between a disengaged position corresponding to the disengaged mode and an engaged position corresponding to the engaged mode. The remote actuator may be operably coupled to the flexible driving member (100), where responsive to actuation of the remote actuator, the flexible driving member (100) engages a) the latching lever (125) to move the latching lever (125) to the engaged position to thereby place the first transmission (110, 120) in the engaged mode; and b) the first transmission (110, 120) to provide drive power from the drive shaft (130) to the first set of wheels (40, 42).

A transmission housing (2) including two housing elements (9) that can be positioned to press against each other and that in the assembled state define: a cavity (13); a shaft (6) projecting at least in part from the housing; a motion transmission mechanism (30) for transmitting motion to said shaft (6), the motion transmission mechanism (30) being housed at least in part inside the cavity (13) of the housing (2); and adhesive connection means (16) for connecting together housing elements (9) that are arranged in the zone where said housing elements (9) are pressed together and referred to as a join plane (10).

The adhesive connection means (16) include a main channel (163) for receiving adhesive surrounding said cavity (13), said main channel (163) comprising a female element (1631) carried by a housing element (9) and a male element (1632) carried by the other housing element (9) with the male element (1632) being engaged at least in part in the female element (1631) in the assembled-together state of said housing elements (9).

A lawn mower includes a housing, a drive source, flaps, a grass clippings container, a grass clippings container weight detection unit, an internal pressure detection unit, and a control unit. If it is determined that a first condition where a change amount per predetermined fixed time of the weight detected by the grass clippings container weight detection unit is below a weight change amount reference value and a second condition where a change amount per predetermined fixed time of the internal pressure detected by the internal pressure detection unit has increased to a internal pressure change amount reference value, are satisfied, the control unit implements control to place the flaps in a substantially horizontal state.

A drive system includes a first transmission, a second transmission and at least one flexible driving member. The first transmission is operably coupled to a first set of wheels to provide drive power to the first set of wheels responsive to engagement of the first transmission. The second transmission is operably coupled to a second set of wheels to provide drive power to the second set of wheels responsive to engagement of the second transmission. The at least one flexible driving member is operably coupled to a remote actuator and a drive shaft of the walk-behind outdoor power equipment device. The at least one flexible member selectively engages one of the first transmission or the second transmission to switch a walk-behind outdoor power equipment device between all wheel drive operation and another drive mode via the remote actuator.

A control unit of a lawn mower performs switching control for switching operation between a first control mode and a second mode. In the first control mode, during rotation of an engine at a first reference rotation speed, in the case where a change amount of rotation speed of the engine per unit time has exceeded a reference speed change amount, the rotation speed is maintained at a second reference rotation speed, and an flap angle is increased. In the second control mode, during rotation of the engine at a second reference rotation speed, in the case where an opening angle of a throttle valve has fallen below a reference opening angle, the rotation speed is maintained at the first reference rotation speed, and the flap angle is decreased. The second reference rotation speed is higher than the first reference rotation speed.

A garden tool power system comprises a motor, a reducer and a transmission shaft. The motor transmits the power to the transmission shaft through the reducer to drive wheels of the transmission shaft to rotate. The reducer comprises a pinion connected to an output end of the motor and a gear engaged with the pinion. The transmission shaft includes left and right shafts connected with each other through a connecting shaft. The gear mounted on the connecting shaft has at least two guiding rods transversely located thereon and two centrifugal blocks located between the guiding rods. Each guiding rod has a spring surrounded therearound and each spring located between two centrifugal blocks has two opposite ends respectively abutted against the corresponding portion of the centrifugal blocks. A fixing sleeve provided on the periphery of the centrifugal blocks is mounted on the transmission shaft and has buckle structures matching with the centrifugal blocks.

An improved electromechanical Blade Clutch Actuator (BCA) that employs an electric gear motor system to provide more economical, convenient and reliable user control with an electric switch to engage/disengage the cutting blades. The user control may be a switch remotely mounted anywhere on the mower for greater design freedom due to the removal of the manual interface. The BCA also incorporates a novel slip clutch for overload protection.
