A mower executes a mowing work while traveling autonomously. Furthermore, the mower includes a mower main body and a first controller that controls an operation of the mower main body so that the mower main body is washed with tap water that is supplied from a washing station. The mower includes, for example, a work unit that executes the mowing work, and the first controller operates the work unit so that the mower main body is washed.

A cleaning system includes a mower that executes a mowing work while traveling autonomously, and a cleaning station that cleans the mower. The cleaning system includes: an acquirer that acquires dirt information relating to a state of dirt of the mower; a determiner that determines at least one of a necessity of cleaning the mower and a method of cleaning the mower, based on the dirt information; and a first cleaning executor that executes a cleaning operation, according to a determination result of the determiner.

A lawnmower (1) is disclosed comprising at least one wheel (3) configured to support the lawnmower (1) during operation. The at least one wheel (3) comprises a rolling surface (5), and the lawnmower (1) comprises a cleaning device (7) configured to clean the rolling surface (5), and an actuator (9) configured to move the cleaning device (7) relative the rolling surface (5). The present disclosure further relates to a method (100) of cleaning a rolling surface (5) of at least one wheel (3) of a lawnmower (1).

A high-efficiency blade for a lawn maintenance tool includes a central axis and a mounting portion located on the central axis. The high-efficiency blade includes a cutting blade and a cutting blade sharpened leading edge. A cleaning blade is vertically offset from the cutting blade and is configured to mulch the associated clippings from vegetation and reduce an associated accumulation of clippings on an underside of an associated mower deck. The lawn maintenance tool can also include a deck having a separation distance between the cleaning blade and an underside of the deck. The deck can include an elevation change to vary the separation distance. The deck and high-efficiency blade can also include a forward or rearward tilt.

A clean out system of a header for an agricultural vehicle including at least one cover having a plurality of perforations and at least one actuating member connected to the at least one cover. The at least one actuating member is configured for moving the at least one cover between a first position to completely cover at least one cutout of the frame of the header for blocking the unwanted material from exiting the header, a second position to at least partially uncover the at least one cutout for permitting the unwanted material to pass through the at least one cutout, and a third position to align at least one perforation of the plurality of perforations with the at least one cutout for permitting the unwanted material to pass through the at least one cutout and the at least one perforation of the plurality of perforations.

A mobile machine is described. In one example, the machine includes a first subsystem comprising propulsion components configured to propel the mobile machine, a second subsystem, a first drive mechanism, a second drive mechanism, a coupling mechanism, and a controller configured to actuate the coupling mechanism to selectively couple one of the first or second drive mechanisms to drive one or more components of the second subsystem with variable speed and direction.

An impulse mechanism for a vibratory device includes an eccentrically weighted shaft that is adapted to be rotated to create vibratory forces. A fan component is mounted on the eccentrically weighted shaft. The fan component has a plurality of fan blades spaced around its periphery.

A general purpose engine includes: a crankcase to support an engine rotary shaft; a cylinder unit extending from the crankcase in a direction perpendicular to an axis of the engine rotary shaft; a cooling fan fixed to one of opposite ends of the engine rotary shaft; and a fan housing configured to have an air induction opening defined therein for the cooling fan and to cover the crankcase and the cylinder unit from one side of the engine rotary shaft. At a position of the fan housing which is opposed to the cooling fin of the cylinder unit, a cleaning access window is defined. The cleaning access window is covered by a debris covering that is capable of being selectively opened and closed. The debris covering has one end portion engaged with the fan housing and the other end portion removably mounted on the fan housing by a magnetic body.

An autonomous mower including a housing; a mowing module, a traveling module, an information collection device, an energy module, a control module and the control module includes an identification unit, and an alarm module. The autonomous mower has a security patrol working mode in which the identification unit analyzes and judges whether an abnormal object exists in the working area according to the information collected by the information collection device; if the abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside. Therefore, the autonomous mower can achieve a security patrol function in addition to having a function of trimming the lawn. The autonomous mower has multiple uses, so as to save the cost.
