Abstract: Presented is a selective active caster steering apparatus for a maintenance apparatus having a first drive unit and a second drive unit. The selective active caster steering apparatus may comprise a caster wheel frame defining a caster swivel axis and a caster spin axis; a caster wheel operationally engaged with the caster wheel frame such that the caster wheel is adapted to be steered about the caster swivel axis; and a first caster steering unit adapted to selectably apply an amount of active torque to the caster wheel about the caster swivel axis as indicated by a first formula. The first formula may determine the amount of active torque to output as a first function of one or more measured parameters.

Abstract: A handle assembly for an autonomous vehicle such as a lawn mower is provided and may include a cradle adapted to receive a mobile computer. The handle assembly may be configured in both an autonomous mode position and a manual mode position. The vehicle may operate autonomously when the handle assembly is in the autonomous mode position, and be adapted to move under manual operator control, e.g., for perimeter training, when the handle assembly is in the manual mode position.

Abstract: The invention provides a garden tool, which comprises a traveling assembly, a travel-driven assembly and a control assembly. The traveling assembly comprises front wheel and rear wheel.
The travel-driven assembly comprises a front-drive mechanism for driving the front wheel and a rear-drive mechanism for driving the rear wheels. The control assembly controls the work of the front-drive mechanism and the rear-drive mechanism, so as to enable the front wheel and the rear wheel to respectively move forward or backward. Compared with the prior art, the garden tool drives the front wheels and the rear wheels to move forward or backward respectively through the front-drive mechanism and the rear-drive mechanism, and thus not only the garden tool automatically walks backward, but also the traveling assembly can be ensured to obtain sufficient power, thereby the garden tool is prevented from slipping when climbing and retreating.

Abstract: A hand push lawn mower includes a body including a cutting blade and an operating device for a user to operate and connected to the body. The body includes a deck, a motor, a height adjustment assembly and a grass baffle. The motor is configured to drive the cutting blade to rotate. The height adjustment assembly is used to adjust the deck to move up and down. The grass baffle is configured to prevent grass clippings from splashing towards the back of the hand push lawn mower. When the height adjustment assembly adjusts the height of the deck, a displacement of the grass baffle in a vertical direction is less than a displacement of the deck in the vertical direction.

Abstract: A lawn mower includes a blade housing and a height adjusting mechanism for adjusting a height of the blade housing with respect to the associated ground. The height adjusting mechanism includes rear wheel support members for supporting rear drive wheels. Each rear drive wheel includes a cover having an exterior cover part and an interior cover part. The interior cover part is directly connected to one of the support members without the use of separate associated mechanical fasteners.

Abstract: A walk-behind machine includes a clutch having a driving state where a motor drives wheels to rotate and an unlocked state where the wheels freely rotate relative to the motor. The clutch includes a movable member and a driving member. The movable member is capable of moving between a locked position where the clutch is in the driving state and an unlocked position where the clutch is in the unlocked state. The driving member transfers power to the wheels by means of friction. When the clutch is in the driving state, the motor drives the wheels to rotate in a first direction, when the motor stops rotating, the wheels rotate in a second direction opposite to the first direction and can drive the driving member to move by frictional force so that the driving member pushes the movable member to move from the locked position to the unlocked position.

Abstract: Outdoor power equipment includes a frame, a power head, a transmission, a pair of rear drive wheels, and a wheel height adjustment mechanism. The power head is coupled to the frame. The transmission is coupled to the frame and operatively coupled to the power head. The transmission includes a drive rotatable member configured to rotate about a first axis. The pair of rear drive wheels are coupled at respective ends of a rear drive axle so that the rear drive axle, and the pair of rear drive wheels coupled thereto, rotate about a second axis different than the first axis. The wheel height adjustment mechanism includes a first bell crank pivotally coupled to the frame about the first axis. A first end of the first bell crank is coupled to the rear drive axle.
