A lawn mower has an electrical port that receives current from an alternator powered by the lawn mower engine. The current and voltage sent the electrical port depend on a flywheel and stator arrangement operatively connected to the alternator. The stator may be replaceable or interchangeable to selectively determine the alternator current and voltage output. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.

An arm support tool attachment includes a shaft extending from a first end to a second end; a clamp positioned at the second end of the shaft, the clamp to removably secure to a handle portion of a tool; and a cuff having an elongated channel to receive and support a user’s arm, the cuff attached to the shaft at the first end; the shaft extends the cuff away from the handle portion of the tool such that the cuff provides user support.

The present invention discloses an automatic operation system. The automatic operation system includes a lawn mower. The lawn mower may include: a housing; a moving module; a cutting module; an energy module, configured to provide energy for the intelligent lawn mower; an image capturing module, configured to capture image information near the intelligent lawn mower, and control movement and/or operation of the intelligent lawn mower according to the captured image information; and a control module, electrically connected to the moving module, the cutting module, and the image capturing module and configured to control the intelligent lawn mower to move and/or operate within an operation region. The intelligent lawn mower includes at least two operation modes, and the image capturing module has at least two operation positions relative to the housing when the intelligent lawn mower operates in the at least two operation modes.

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device configured to supply power to at least one of the walking motor or the driving motor, the first energy storage device detachably mounted to the frame and enabled to supply power to a handheld power tool when detached from the riding lawn mower; and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor; wherein a ratio of a total energy of the second energy storage device to a total energy of the first energy storage device is greater than or equal to 2 and less than or equal to 20.

A riding lawn mower, including: a frame; a seat; a walking assembly and a walking motor; a cutting assembly and a driving motor configured to drive the cutting assembly; a first energy storage device configured to supply power to at least one of the walking motor or the driving motor, the first energy storage device including at least one first energy storage unit, the first energy storage device detachably mounted to the frame and enabled to supply power to a handheld power tool when detached from the riding lawn mower; and a second energy storage device configured to supply power to at least one of the walking motor or the driving motor, the second energy storage device including at least one second energy storage unit; wherein an energy density of the second energy storage unit is different from an energy density of the first energy storage unit.

A carburetor includes a carburetor bowl, a fuel supply pipe, a fuel drain pipe, and a valve. The carburetor bowl is configured to store fuel and provide the fuel to an air passage. The fuel supply pipe is connected a fuel tank and the carburetor bowl. The fuel drain pipe is connected to the carburetor bowl and the fuel supply line. The valve for the fuel drain pipe is configured to open and close in response to an orientation of the carburetor.

A handle adjustment assembly is attached to a walk-behind lawn mower, wherein the handle adjustment assembly is rotatably adjustable relative to a deck of the mower to allow the handle to be adjusted to multiple different heights relative to the ground at distinct operative positions. The handle adjustment assembly is also rotatable to allow the handle to be adjusted to a stored position adjacent to the deck, wherein the mower can be stored in a substantially vertical orientation.

A self-adjusting mower deck gauge wheel includes a first hydraulic cylinder fluidly connected to a second hydraulic cylinder. A gauge wheel is rotatably mounted on a gauge wheel shaft slideable in the first hydraulic cylinder between a fully extended position and a fully retracted position. In the fully retracted position, the mower deck rests flat on the ground and is not supported by gauge wheels. An orifice between the first and second hydraulic cylinders provides a high damping rate to slow travel of the gauge wheel shaft between the fully extended and fully retracted positions. A coil spring with a low spring rate also may be connected to a piston in the second hydraulic cylinder.

A carburetor includes a carburetor bowl, a fuel supply pipe, a fuel drain pipe, and a valve. The carburetor bowl is configured to store fuel and provide the fuel to an air passage. The fuel supply pipe is connected a fuel tank and the carburetor bowl. The fuel drain pipe is connected to the carburetor bowl and the fuel supply line. The valve for the fuel drain pipe is configured to open and close in response to an orientation of the carburetor.

An information processing device includes: an image acquiring section that acquires image data of an image of a plant; a form recognizing section that recognizes at least either (i) a shape of the plant or (ii) an end portion of the plant, based on the image data acquired by the image acquiring section; and a deciding section that decides at least one of (a) a level of water content in a medium of the plant, (b) whether water-supply to the plant is necessary or not, and (c) an amount of water-supply to the plant, based on a feature of at least either the shape of the plant or the end portion of the plant that is recognized by the form recognizing section.
