To enable the rotational speed of the cutter blade to be set variably and to allow the operation therefor to be performed with ease and accuracy, multiple switches (74, 76) for setting the rotational speed of the cutter blade electric motor (6) to mutually different rotational speeds, and multiple operation buttons (78, 80) provided for the respective switches (74, 76) are included on a handle (20), wherein the operation buttons (78, 80) have operation parts (78A, 80A) provided with mutually different sizes.

A walk-behind self-propelled working machine includes a main body, an operation switch, and a handle device. The main body includes a moving assembly and a drive motor. The operation switch is connected to the drive motor. The handle device is connected to the main body and includes an operation member, a connecting rod, and a sensing device. The operation member includes a gripping portion for a user to hold. The connecting rod is connected to the main body. The sensing device is configured to sense a thrust that is applied to the handle device to drive the walk-behind self-propelled working machine and further includes a pressure sensor and a pressing member. When the gripping portion receives the thrust, the pressing member applies a force along a preset straight line to the pressure sensor to drive the pressure sensor to deform.

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 walk power mower having a cutting deck supported upon the ground by a front and rear wheel(s). The mower includes a traction drive system incorporating a bidirectional transmission adapted to propel the mower alternatively in both forward and reverse directions. In some embodiments, the mower may include a single bidirectional transmission (e.g., powering only rear wheel(s) or only front wheel(s) of the mower), while in other embodiments, two bidirectional transmissions may be provided to power both the front and the rear wheel(s). In other embodiments, the mower may include a bidirectional transmission powering the rear wheel(s), while the front wheel(s) may be attached to the deck via a caster assembly.

The lawn mowing device comprises a mower and a controller. The lawn mowing device may be adapted to be operated by a user from a stationary position. Movements of the mower may be controlled from the stationary position using the controller. The mower may comprise a first engine for rotating a blade located under a deck of the mower and a second engine for propelling the mower forward. The controller may comprise a control bracket coupled to the top of the deck and a telescoping shaft that is coupled to the top of the control bracket via a universal joint. The user may control the movements of the mower by manipulating a distal end of the telescoping shaft.

A lawn mower includes a housing (1), a traveling wheel for supporting the lawn mower (100), a self-propelled motor for driving the traveling wheel, and a control circuit board (5) for controlling turning-on and turning-off of the self-propelled motor. The traveling wheel includes a pair of front traveling wheels (31) and a pair of rear traveling wheels (32), and the self-propelled motor includes a first self-propelled motor (41) and a second self-propelled motor (42). The lawn mower further includes a first control element and a second control element, the first control element is configured to control the control circuit board to turn-on or turn-off the first self-propelled motor, and the second control element is configured to control the control circuit board to turn-on or turn-off the second self-propelled motor. The lawn mower can be driven in two-wheel drive or four-wheel drive as required, which is convenient to operate and maintain.

A transmission control system and method for a lawnmower having a battery and an electric drive transmission that can include a propulsion motor and a propulsion motor driver. The control system can include a clutch lever, a speed lever, a cable connected to the clutch lever and the speed lever, a hall sensor in electrical communication with the propulsion motor driver, and a clutch arm connected to the cable and configured to actuate the hall sensor to change a speed of the electric transmission.

A small push-type lawn mower that can be converted into a stand-on riding mower. The mower includes a platform at the rear of the mower deck, and a handle assembly that can be pivoted forwardly making room for a user to step onto the platform. The handle assembly includes controls that drive electric motors that power the rear wheels allowing the user to ride the mower. The handle assembly can be pivoted rearwardly so that the user can access and grab the handle assembly and push the mower while walking behind.

A garden tool, including a main body, a walking wheel mounted on the main body, a self-propelled motor for driving the walking wheel, and a control panel disposed on the main body. The control panel includes a self-propelled control assembly. The self-propelled control assembly includes a self-propelled start paddle and a speed regulating button. Pressing the self-propelled start paddle activates self-propelled operation of the garden tool. The self-propelled start paddle can be released for a short time and the speed regulating button can be adjusted within the short time. The self-propelled start paddle can be re-pressed within the short time and after the speed regulating button is adjusted, and the garden tool maintains the self-propelled operation.
