A drive system of a lawn mower includes a drive belt, a drive pulley, a drive shaft pulley and an idler pulley. The drive pulley is disposed at a rocking transmission of the lawn mower to transfer drive belt motion to power for a set of wheels of the lawn mower via the rocking transmission when the rocking transmission is engaged. The drive shaft pulley is operably coupled to a drive shaft of the lawn mower to rotate responsive to rotation of the drive shaft. The drive shaft pulley engages the drive belt responsive to engagement of the rocking transmission.

Vehicle drive and control system

A drive and control system for a lawn tractor includes a CAN-Bus network, a plurality of controllers, a pair of electric transaxles controlled by the plurality of controllers, and one or more steering and drive input devices coupled to respective sensor(s) for sensing user steering and drive inputs. The plurality of controllers communicate with one or more vehicle sensors via the CAN-Bus network. The plurality of controllers receive the user's steering and drive inputs and posts on the CAN-Bus network and generate drive signals to obtain the desired speed and direction of motion of the lawn tractor.

Switch control mechanism for garden tool

Disclosed is a switch control mechanism for a garden tool, the mechanism comprising handles, a switch and shift rods. Triggers are arranged on the handles, and the handles can rotate around the axes thereof. The triggers are connected to the shift rods by pull ropes, and the contact faces between the pull ropes and the triggers are spherical faces. The handles of the switch control mechanism for the garden tool can rotate within 360 degrees, so as to satisfy different operators, and can ensure that a user can control the switch of a machine wherever the handles are placed.

Operation safety assembly for a lawncare apparatus

A lawncare apparatus includes a main body, multiple wheels supporting the main body, a cutting blade disposed in the main body, a motor driving the cutting blade, and an operating arm connected to the first end of the main body. The distance in the horizontal direction between the axial central line of the cylindrical gripping portion of the operating arm and the axes of the elongated handle of the main body along the length direction is less than 5 cm. Because of the structure mate relationship between the operating arm and the cylindrical gripping portion, the operator feels more comfortable during the transporting process, the volume of lawncare apparatus during transporting is reduced and the convenience of transporting is improved.

Power equipment

Walk-behind power equipment includes: a main body including front and rear wheels; a work unit provided on the main body; a work motor that drives the work unit; a travel motor that rotates the rear wheel; a handle extending from the main body rearward and upward; a posture detector that detects a rearward tilted state of the main body in which the rear wheel is in contact with a ground and the front wheel is not; and a control unit that drive-controls the work motor and travel motor, wherein when the main body is in the rearward tilted state, the control unit causes a rotational speed of the travel motor to be reduced compared to when the front wheel is in contact with the ground, or causes a rotational speed of the work motor to be reduced compared to when the front wheel is in contact with the ground.

Work vehicle

A work vehicle includes a vehicle body, a pair of left and right driving wheels that movably support the vehicle body, a pair of motors capable of rotatably driving the left and right driving wheels respectively, a pair of maneuvering levers pivotally supported to the vehicle body to be pivotable about a horizontal axis extending in a vehicle body transverse direction and capable of adjusting rotational speeds respectively of the left and right driving wheels and a pair of dynamic vibration absorbing portions supported to respective free end portions of the maneuvering levers and capable of suppressing vibrations of the maneuvering levers.

Starter system for an engine

Outdoor power equipment includes an internal combustion engine including an electric motor, a battery receiving port, a rechargeable battery removably attached to the battery receiving port, wherein the rechargeable battery is configured to power the electric motor to start the engine, an implement driven by the internal combustion engine, a release mechanism movable to an engaged position to put the implement in a ready-to-run condition in which the implement is ready to be driven by the engine, a run sensor configured to detect the ready-to-run condition, a switch actuated by the release mechanism, and a control module coupled to the switch so that the switch provides a signal to the control module when the release mechanism is in the engaged position and the control module turns on the electric motor to start the engine in response to the signal from the switch and the run sensor detecting the ready-to-run condition.
