Abstract: A power tool includes a housing, a trigger, a motor supported within the housing, a saw blade interconnected to the housing by a support arm and drivably coupled to the motor, a main handle integrally formed with the housing, an auxiliary handle coupled to the housing and disposed between the saw blade and the main handle, and a battery receptacle defined by the housing and positioned beneath the main handle. The battery receptacle is configured to receive a battery pack to supply electrical current to the motor. The power tool further includes a splash guard integrally formed with the housing and positioned between the battery receptacle and the saw blade.

Abstract: A battery for equipment having a charging system providing a charging voltage is provided. The battery includes a primary power supply, a secondary power supply, and a battery management system configured to at least one of (a) selectively increase the charging voltage to a boosted voltage and (b) selectively decrease the charging voltage to a bucked voltage, and provide at least one of the boosted voltage and the bucked voltage to the primary power supply.

Abstract: An engine that includes an air intake, a combustion chamber, an air passageway that is configured to channel air from the air intake toward the combustion chamber, a carburetor, a throttle plate, and a fuel atomizer. The carburetor includes a fuel bowl with a fuel well, a carburetor passageway that is fluidly coupled to the air passageway and configured to channel air and fuel to the combustion chamber, and a carburetor nozzle that has an inlet configured to receive fuel from the fuel well and an outlet disposed proximate to a constricted section of the carburetor passageway. The throttle plate is disposed downstream of the carburetor nozzle, and the fuel atomizer is configured to provide fuel to the carburetor passageway.

Abstract: A tractor includes a prime mover, a driven implement selectively engaged with the prime mover, and a switch for selectively engaging and disengaging the driven implement with the prime mover. The switch has three positions including a disengaged position, a momentary position, and an engaged position located between the disengaged position and the momentary position. The prime mover can be started with the switch in the disengaged position. The prime mover can be started with the switch in the engaged position when the switch was previously moved to the momentary position before being moved to the engaged position, such that after operation of the prime mover is stopped, the prime mover can be restarted without changing the position of the switch.
