摘要： In an auger snow plow, right and left forward rotating augers and right and left backward rotating augers are disposed on a same axis and aligned in a width direction of an auger housing. A blower housing is disposed at a rear portion of the auger housing and also positioned at a widthwise center of the auger housing. A blower is disposed inside the blower housing. The right and left forward rotating augers are positioned at least in an entire range of a width of the blower housing. The right and left backward rotating augers are separately positioned on both sides of the right and left forward rotating augers and positioned only at a more outer side than the width of the blower housing in the width direction.

摘要： A snow removal machine has: a storage unit that stores a vehicle speed coefficient map indicating the relationship between an incline angle and a vehicle speed coefficient for decreasing an instructed vehicle speed; a vehicle speed coefficient setting unit that sets the vehicle speed coefficient on the basis of a detected incline angle and the vehicle speed coefficient map; and a vehicle speed setting unit that sets the vehicle speed of a traveling unit by way of multiplying the instructed vehicle speed by the set vehicle speed coefficient. The vehicle speed coefficient map sets the vehicle speed coefficient so same is smaller for larger incline angles when at least the traveling unit is going forward on an upslope. A travel control unit controls a drive source so that the traveling unit travels at the set vehicle speed set by the vehicle speed setting unit.

摘要： An autonomous lawn mower includes a movable cover covering a traveling frame and holding devices holding the movable cover. Each holding device includes a holding shaft and a shaft holding unit. The holding shaft includes a lower half portion and an upper half portion. The shaft holding unit holds the lower half portion accommodated in an accommodating portion of the traveling frame such that the lower half portion can slide in only a horizontal direction. The upper half portion extends through a through hole of the movable cover by extending upward from the traveling frame, thereby holding the movable cover so that the movable cover is vertically displaceable. A coil spring intervenes between a receiving portion and an upper wall of the movable cover. One holding device includes a detector which detects the slide displacement amount of the lower half portion.

摘要： Riding lawn mower switchable between mulching and bagging modes includes: a delivery passage for delivering grass, cut by cutting blades in a housing, from the housing to a receptacle by delivering air; and a scroll guide provided in an entrance of the passage for directing the grass clippings to the passage. An overall shape of the scroll guide as viewed in top plan is a substantial isosceles triangle extending into the housing while tapering forward from a scroll guide's base section located in the entrance and as viewed in side elevation is a substantial triangle tapering forward from the base section. Left and right side surfaces of the scroll guide each comprises lower and upper slanting surfaces formed as different slants, each of which gradually increases in area from the distal end of the scroll guide toward the base section.

摘要： A breather device and a snow removal machine having the breather device have a casing into which blowby gas of an engine flows, an air suction port for letting out gas from the inside of the casing, and a gas-liquid separation mechanism for separating moisture contained in the blowby gas. The gas-liquid separation mechanism separates an inlet, which allows the blowby gas to flow in, and the air suction port by a predetermined distance, and has the air suction port positioned above a liquid path through which the moisture flows. A gas path allows the blowby gas to flow from the inlet to the air suction port without passing through an air cleaner element.
