A walk-behind lawnmower and accompanying method of use allows for height adjustment of the cutting deck relative to all four wheels simultaneously. This is achieved using a linkage that runs along the cutting deck and that connects the front and rear wheel assemblies. Movement of the entire mechanism is achieved using a lever operatively connected to the linkage. The linkage is retained in place through the use of a locking mechanism. The locking mechanism includes a locking pin, a pin engagement mechanism, such as a lug, provided on the linkage, and an array of pin receptacles spaced longitudinally along the cutting deck. The pin engagement mechanism selectively engages the pin when the pin engages a designated pin receptacle on the cutting deck, retaining the cutting deck at a height determined by the prevailing location of the pin which, in turn, is determined by the selected pin receptacle.

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 rod mechanism for a garden tool having a main body includes a first rod pivotally connected to the main body and movable between an in-use position and a storage position. A locking component engages the main body to lock the first rod in one of the in-use position and the storage position. An actuator moves between a released position and a triggered position, the actuator when in the triggered position unlocking the locking component from the main body, the actuator when in the released position orienting the locking component so as to be lockable to the main body. A second rod connected to the first rod moves to a preset position allowing the actuator to move to one of the triggered position or the released position. A position sensor on the main body generates a sensing signal when the first rod pivots to at least one of the in-use position and the storage position.

The present utility model discloses a hybrid grass cutting apparatus, comprising a strimmer assembly, the strimmer assembly comprising a cutting head assembly located at an end remote from a handle and connected via a connecting rod, the cutting head assembly comprising a cutting tool and a guard located close to the cutting tool. The hybrid grass cutting apparatus further comprises a grass cutter frame, the grass cutter frame having an opening which accommodates the guard and through which the cutting tool can pass; and an engagement feature is provided between the grass cutter frame and the guard, enabling a user to engage the strimmer assembly with the grass cutter frame or remove the strimmer assembly from the grass cutter frame without any need to use an additional tool.

A propulsion control system for a walk-behind self-propelled machine including a drive transmission and at least one wheel selectively driven by the drive transmission can include a sensor array and a controller. The sensor array can be configured to measure a first angular velocity about a first rotational axis of the machine and a second angular velocity about a second rotational axis of the machine, where the second rotational axis is different from the first rotational axis. The controller can be in electrical communication with the sensor array and configured to place the drive transmission in an off state when the drive transmission is in an on state, the first angular velocity is greater than a first threshold, and the second angular velocity is greater than a second threshold.

A walk power mower has a deck with an upwardly and rearwardly extending handle behind which a use walks when operating the mower. The mower is self-propelled by a variable speed traction drive. The handle includes a slidable handle grip for engaging and selecting a speed of the traction drive to control the ground speed of the mower. Forward ground speed is set by pushing the handle grip forwardly on the handle from a neutral position. Reverse ground speed if available is by pulling the handle grip rearwardly from its neutral position. The handle grip follows a curved path as it moves forwardly or rearwardly to flatten the path of travel of the handle grip from the travel that would have occurred absent the curved path.

A power assembly and a garden tool having the power assembly. The power assembly includes a housing, a driving unit received in the housing and a power supplying unit received in the housing for powering the driving unit. The driving unit includes a driving motor and a control panel assembly located upon the driving motor. The housing has at least one heat dissipation air duct formed therein for airflow passing through the driving unit. The heat dissipation air duct has an air inlet for air intaking and an air outlet for air flowing out, and the air outlet is located at a bottom of the housing and open towards a lateral side of the housing. So that the airflow entering the housing through the air inlet can sequentially flow through the control panel assembly and the driving motor, and finally flows out the housing through the air outlet to take away the heat generated by the driving unit, the working temperature of the driving unit can be reduced and the working efficiency of the power assembly can be improved.
