Mowing systems include a mower and a remote control unit such as a handheld unit, between which is provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. Aspects of the invention relate to: an enable switch on the remote control unit that requires activation within a specified time before activating a drive system or PTO unit; sharing diagnostic information between the mower and remote control unit and emitting user-detectable warnings in response to the shared information; reducing a danger level of the system when a proximity between the mower and the remote control unit is too small; and using inclinometers in the mower and the remote control unit to control operation of the mower based on tilt angles of both the mower and the remote control unit.

An internal combustion engine includes an engine block, a blower housing configured to direct cooling air to the engine block, an electric starting system, and a crankshaft configured to rotate about a crankshaft axis. The electric starting system includes an electric motor and an energy storage device located within the blower housing. The energy storage device is electrically coupled to the electric motor to power the electric motor, and is positioned above the crankshaft. When the starter motor is activated, the electric starting system rotates the crankshaft to rotate the engine for starting.

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 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.

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half positioned adjacent the front of the engine and a cool half opposite the hot half, and an electric starter system positioned within the blower housing. The electric starting system includes a starter mount assembly coupled to the blower housing, an electric starter motor retained by the starter mount assembly and positioned in the cool half, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

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.

A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.

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.

A riding lawn mower includes a power output assembly including a mowing element, a cutting motor for driving the mowing element to move, and a cutting control module for controlling the cutting motor; a walking assembly including a walking wheel, a walking motor for driving the walking wheel to travel, and a walking control module for controlling the walking motor; and a first operating component configured to set starting modes of the walking motor. The first operating component has a first operating state configured to start the walking motor in a first starting mode, and a second operating state configured to start the walking motor in a second starting mode. In the first starting mode, the walking motor starts at a first starting acceleration. In the second starting mode, the walking motor starts at a second starting acceleration. The second starting acceleration is greater than the first starting acceleration.
