A garden tool includes a gasoline engine and a power source, the gasoline engine including a fuel supply system and an ignition system. The garden tool may further include a control system with at least one sensor used for collecting a working condition signal of the gasoline engine and a controller used for receiving the working condition signal and controlling the fuel supply system and/or the ignition system according to the working condition signal received. The power source may provide a power supply for the fuel supply system, the ignition system, and the control system through the controller.

A harvester capable of autonomous travel in a field includes: a harvesting unit that harvests a crop from the field; a conveyance device that conveys, toward the rear of a harvester body, a whole culm of the harvested crop harvested by the harvesting unit; a detection sensor that detects a drive speed of the conveyance device; and a clog determining unit that determines a clog of the harvested crop in the conveyance device on the basis of the drive speed. The clog determining unit outputs a vehicle stop command that stops the harvester body when the drive speed becomes lower than a pre-set first threshold during the autonomous travel.

An agricultural vehicle including a frame, a prime mover supported by the frame, and a header connected to the frame. The header includes at least one drive line, at least one transmission, at least one rotating cross shaft, and at least one gearbox operably connected to the at least one rotating cross shaft. The at least one gearbox includes a housing connected to the header and configured for housing a working fluid. The housing has an inlet, an outlet, and an end. The at least one gearbox also includes a gear train housed within the housing and an auxiliary sump connected to the end of the housing and fluidly coupled to the inlet and the outlet of the housing such that the working fluid circulates through the housing and the auxiliary sump.

Various embodiments of a grounds maintenance vehicle are described herein. The vehicle includes a frame and an implement connected to the frame. The implement includes a housing, a first spindle pulley, and a second spindle pulley. The vehicle further includes a power system having a prime mover and an implement drive system. The implement drive system includes a drive pulley connected to the prime mover, an idler pulley, and an endless belt engaging the drive pulley, the idler pulley, the first spindle pulley, and the second spindle pulley. A first longitudinal distance between an idler pulley axis and a drive pulley axis is greater than a second longitudinal distance between a first spindle pulley axis and the drive pulley axis and a third longitudinal distance between a second spindle pulley axis and the drive pulley axis.

A pair of mower deck lifting ramps are mounted to a top surface of a mower deck for supporting a pair of tractor tires to ride over belts and pulleys on one side of the deck. A first carrier engagement member and a second carrier engagement member are attached to each drive-over ramp. The first and second carrier engagement members engage the upper and lower parts of a carrier attached to a lift arm of a loader to raise and turn the mower deck.

Various embodiments of a grounds maintenance vehicle are disclosed. The vehicle includes a frame and a control tower disposed at or near a rear end of the frame. The control tower includes a support structure that defines an interior space of the control tower and a nonplanar removable skin connected to the support structure. The removable skin includes a front side disposed over a front side of the support structure and a lateral side disposed over at least one of a left side or a right side of the support structure. A portion of at least one of the front side or lateral side of the removable skin is disposed above an uppermost surface of the prime mover. Further, the removable skin is adapted to be at least partially removed from the support structure to facilitate additional access to the interior space of the control tower.
