A lawn mower includes a cutter blade that cuts grass, a body portion including a housing containing the cutter blade, and a grass clippings discharge passage that discharges grass clippings cut by the cutler blade from the housing, a grass clippings container that contain grass clippings, and an opening degree adjust valve. The grass clippings discharge passage includes an upstream opening connected to the housing, and a downstream opening for ejecting grass clippings to outside of the body portion. The opening degree adjust valve is provided at the downstream opening of the grass clippings discharge passage and adjusts an opening degree of the downstream opening.

A lawn mower includes: a rotation shaft coupled to a power source and extending in an approximately vertical direction; a blade configured to rotate integrally with the rotation shaft; and a housing having a downward opening and accommodating the blade such that the blade is rotatable; and a maintenance tool provided on the housing, the maintenance tool being contactable with the blade from the above. A cutting portion of the blade is capable of moving between a maintenance position at which the cutting portion is contactable with the maintenance tool and an operating position at which the cutting portion mows a lawn.

Lawn mower having a maintenance tool for maintaining a cutting blade

A snow plow, includes a snow plowing part in the front of a machine body having a wheel and a blade; and an operating handle extending rearward from the machine body. The blade is provided at the machine body to be able to be lifted or lowered between a storage position at which the blade is lifted above lowermost surface of the wheel and a usage position at which the blade is lowered below the lowermost surface of the wheel. Any one of the operating handle and the machine body includes an operating member configured to operate the blade such that the blade is lifted or lowered between the storage position and the usage position.

Snow plow

A working machine includes a throttle cable for transmitting an amount of operation of a throttle lever to a throttle valve, upper and lower guide rollers for guiding the throttle cable, and a throttle cable tightening/loosening means including a pivotable arm portion having a pressing roller located between the upper and lower guide rollers. The working machine further includes connecting means interconnecting the arm portion and a clutch lever. Operation of the clutch lever moves the pressing roller between a tightening position to tighten the throttle cable and a slackening position to slacken the throttle cable.

Working machine

A snow removal machine, in which an engine drives an auger and a blower, includes a mode switching operation section for selecting and switching to any one of a plurality of control modes differing from each other in engine output control characteristic; and a control section for controlling the engine by executing any one of the plurality of control modes in accordance with an operation signal output from the mode switching operation section. The control section makes a determination as to whether an operating state of the engine in the currently-executed control mode is in a recommended operating range preset on the basis of at least a rotating speed and degree of throttle opening of the engine, and instructs a display section to display a result of the determination.

Snow removing machine includes an auger for removing accumulated snow, an accumulated snow height detection section for detecting a height of accumulated snow in front of the auger, an auger lifting and lowering section for lifting and lowering the auger, and a control section for controlling the auger lifting and lowering section to lift the auger in response to detection, by the accumulated snow height detection section, of the accumulated snow. By the provision of the accumulated snow height detection section, the present invention can save a human operator a trouble of setting in advance a target height position of the auger and thereby alleviate a load on the human operator.

Snow removing machine

A self-propelled snow remover has a machine body, a snow-removing implement mounted to a front part of the machine body for undergoing rolling and vertical movement relative to the machine body, and an operating unit mounted to a rear part of the machine body. An alignment operating member is mounted to the operating unit for rolling and vertically moving the snow-removing implement. The alignment operating member is disposed on one of opposite sides of a widthwise central line of the machine body. A return operating member is mounted to the operating unit for automatically returning the snow-removing implement to a predetermined reference position. The return operating member is disposed proximate to the alignment operating member at a position closer to the widthwise central line of the machine body than the alignment operating member and further towards the rear part of the machine body than the alignment operating member.

Self-propelled snow remover

Operation mechanism of a working machine includes a main clutch lever pivotably provided on an operating handle, and a pivot member operable in interlocked relation to pivoting operation of the main clutch lever. The pivot member pivots about a pivot point differing in position from a pivot point of the main clutch lever. When fully pulled by pivoting operation of the main clutch lever, the cable member is located nearest to the pivot point of the pivot member, so that force reverse-pivoting the pivot member is reduced.

Operation mechanism of working machine

A walk-behind self-propelled working machine has a machine body, a working unit mounted on the machine body to perform a working operation, an engine mounted on the machine body to drive the working unit, and a traveling unit mounted on the machine body and drivable to cause the machine body to travel. A control unit controls operations of the working unit and the traveling unit. An operating section is operatable by a human operator to provide signals to the control unit to control operations of the working unit and the traveling unit. A mode selector switch is mounted on the operating section for operation by the human operator to select one working operation mode from among plural alternative working operation modes that are set in advance in the control unit on the basis of a combination of a travel speed of the machine body, a revolving speed of the engine, and an opening of a throttle valve associated with the engine.

Walk-behind self-propelled snow removing machine

A snow removing machine has an auger for plowing and collecting snow, a rotatable blower for throwing snow collected by the auger, and a shooter for guiding the snow thrown by the blower so that the snow reaches a selected point. The blower has a central shaft part and blades extending radially outwardly from the shaft part. Each of the blades has one pair of laterally spaced guide walls projecting from a distal end portion thereof in a direction of rotation of the blower. The pair of guide walls for each of the blades extend divergently from each other towards a distal end of the blade.

An agricultural wheel tire has a tire tread having first and second lateral edges defining the width of the tire tread, and two sets of lugs. Each lug of the first set extends from a center of the tread width and terminates at the first lateral edge of the tire tread. Each lug of the second set extends from the center of the tread width and terminates at the second lateral edge of the tire tread. The first and second sets of lugs extend in an alternating manner in a circumferential direction of the tire tread so that corresponding side and end surfaces of adjacent first and second lugs and corresponding surfaces of the tire tread form substantially spherical-shaped depressed portions of the tire tread. The spherical-shaped depressed portions are arranged in the circumferential direction of the tire tread so that when the wheel tire is driven on soft soil, the spherical-shaped depressed portions engage and are buried in the soft soil and the soft soil is gathered inward of the spherical-shaped depressed portions and gradually hardened so that soft soil located between and surrounding the adjacent first and second lugs increases in hardness to thereby prevent the wheel tire from sinking into the soft soil so that the wheel tire has sufficient driving force.
