A gardening tool, such as a mower, has a main body having an accessory, such as a mowing blade, and a motor for driving the accessory. A handle is rotatably connected to the main body. At least one operation assembly is associated with the handle for being operated by a user to control the motor when the handle is located in a predetermined position. A control system prevents the motor from being controlled by the operation assembly and halts the motor when the handle is located out of the predetermined position.

A lawn mower includes a pair of left and right main frames 17, an engine E mounted to the pair of left and right main frames 17, a radiator for cooling water that cools the engine E, a cooling fan 11 for feeding cooling air to the radiator, and a hood 9 accommodating the engine E, the radiator and the cooling fan 11. An air deflector plate 34 is provided between the pair of left and right main frames 17 and configured to change direction of cooling exhaust air flowing toward a ground surface.

An outdoor power equipment unit, such as a lawn mower, includes a frame movable over the ground. A handle assembly is provided on the frame to allow an operator to walk on the ground behind the handle assembly while operating the unit. A traction drive and a ground grooming or working implement are carried on the frame. A traction control hand grip and an implement control bail are carried on the handle assembly. Both the hand grip and the bail are movable relative to the handle assembly by flexure provided by first and send compliant mechanisms.

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.

A gardening tool, such as a mower, includes a main body and a handle rotatably connected to the main body. The main body includes a motor. The handle includes a plurality of telescopic members slidably connected to each other. The mower further includes a operation assembly for being operated by a user to activate the motor and a control system for sending a control signal to enable or disable the operation of motor by the operation assembly when the handle is out of a secure state.

An electric mower includes a chassis; and a walking device, a mowing device, a power device, a handle device, and a back grass discharging device arranged on the chassis. The power device drives the operation of the walking device and the mowing device, the back grass discharging device discharges the grass cut by the mowing device, and the handle device controls the electric mower. The power device of the electric mower uses a hybrid power system formed by DC power supply and AC power supply.

In one aspect, power equipment includes a cutter blade operation lever, a left rotary shaft, an operated member operated by the left rotary shaft to control driving of a cutter blade, and a releasable engagement mechanism provided between the left rotary shaft and the cutter blade operation lever. The releasable engagement mechanism is configured to release a force transmitting engagement between the cutter blade operation lever and the left rotary shaft to allow the cutter blade operation lever to rotate relative to the left rotary shaft when an excessive force is applied to the cutter blade operation lever in a direction to rotate the left rotary shaft beyond a normal rotational angle range.

In one aspect, electric power equipment includes: a horizontally extending left rotary shaft operably connected with a cutter blade operation lever; a horizontally extending right rotary shaft operably connected with a travel operation lever; and a cutter blade on/off switch and a potentiometer for setting a travel speed arranged at a laterally central position substantially between the left and right rotary shafts, such that the cutter blade on/off switch is operated by the left rotary shaft and the potentiometer is operated by the right rotary shaft.

A variable speed control system and method for a walk-behind working machine includes a control system base, a control lever selectively movable with respect to the control system base between two operating positions, a mode actuator positioned on the control system base for toggling between a plurality of control modes, and a control unit in communication with the control lever, the mode actuator, and a machine component. The control unit selectively controls the operation of the machine component between a minimum operating speed and a variable maximum operating speed. The control unit applies a different acceleration profile to accelerate from the minimum operating speed to the variable maximum operating speed depending on the control mode selected.

A stepless speed regulating control mechanism for a mower, which comprises a push handle, a self-propelled lever, a speed regulating cable and a regulating mechanism; the mower has a base and a self-propelled device; the regulating mechanism comprises a regulating sleeve and a speed regulating sleeve; the self-propelled lever pulls the regulating sleeve and causes the speed regulating sleeve to move simultaneously with the regulating sleeve, so as to pull the speed regulating cable, and the speed regulating sleeve can move relative to the regulating sleeve, so as to pull the speed regulating cable. The stepless speed regulating control mechanism of a mower is not only convenient for speed regulation and for stepless speed regulation, but also reasonable in design and convenient for speed regulation operation without causing confusion and misoperation. Besides, the stepless speed regulating control mechanism is low in cost, and easy to manufacture and operate.
