Abstract: A self-propelled walk-behind snowplow vehicle has a vehicle body and a vertical engine mounted on an upper part of the vehicle body. The vertical engine has a crankshaft disposed generally vertical and a cylinder head disposed generally horizontal to a longitudinal direction of the snowplow vehicle. The cylinder head projects from the vehicle body in a rearward direction of the snowplow vehicle. Left and right traveling units are mounted on a lower part of the vehicle body at left and right sides thereof. A muffler is connected to the engine and is disposed below the engine and located between the left and right traveling units. The vehicle body and the left and right traveling units together define a downward opening space within which the muffler is disposed.

Abstract: An auger device of a snow removal machine in this invention has left and right augers and left and right driving tines mounted on left and right auger shafts, respectively. Each auger has an outer auger blade, an intermediate auger blade and an inner auger blade each mounted at one end on the left or right auger shaft. The outer auger blade and inner auger blade are arranged along a first helical path. The intermediate auger blade is arranged 180° out of phase with the first helical path. The left and right driving tines bite into snow, thereby serving as anchors for preventing lifting of the left and right augers.

Abstract: A snow blower augers snow scrapped from a path to a fan. The fan is co-axial with the auger at one end of an auger housing. A fan shaft extends through an auger tube. The fan shaft is supported on one end by a fan housing bearing attached to the housing and at the other end by a bearing in the auger tube. The auger is supported at one end by a drive housing bearing attached to the housing and at the other end by a bearing on the fan shaft. This arrangement makes it possible to have an open passage for the snow to move from the auger to the fan.

Abstract: A device is disclosed, for use with a snow blower being of the type having an auger, and allow it to operate while moving backwards. The device principally consists of a concave blade mounted on a snow blower, which pivots between an operative position where the blade extends close to ground and the concave surface of the blade extends in front of the auger in such a way that the blade scrapes the snow and directs it towards the auger when the snow blower is lifted up to let the snow pass under it and moves backwards, and an inoperative position where the blade is raised to a height sufficient to let the snow reach the auger when the snow blower moves forwards. A snow blower equipped with a device as defined above, for operating while moving backwards, is also disclosed as well as a method for blowing snow with a snow blower equipped with that device.

Abstract: A snow blower is provided with cutting devices which are housed within, but project beyond, a housing provided for the blower's auger. As the cutting devices engage snow during the blower's advance, the cutting devices move in a direction which tends to urge the forward portion of the blower downwardly.

Abstract: A snowblower chisel attachment includes an oscillatable elongate blade member oscillatably disposed at a bottom front of a snowblower housing; a pair of support arms pivotally suspended from the sidewalls of the housing and being secured to the oscillatable elongate blade member; a pair of stub shafts journaled through the sidewalls of the housing; a pair of three lobed cams mounted to the stub shafts for contacting and urging the support arms and intervally urging the oscillatable elongate blade member forwardly relative to the housing; a plurality of sprockets for rotating the stub shafts and the cams; a pair of biased elements for urging the oscillatable elongate blade member rearwardly toward the housing; and skid members for vertically positioning the oscillatable elongate blade member relative to the surface.

Abstract: The present invention provides a poultry house cleaner apparatus that is adapted to easily, quickly and efficiently clean, scrape and remove the manure of the chicken from the side walls of the chicken houses. This poultry house cleaner apparatus is adapted to be removably secured to a conventional tractor and comprises an angled blade having a sliding plate attached thereto. The sliding plate includes a somewhat L-shaped configuration for enabling one portion to be slideably mounted to the blade while a second portion extends outwardly and perpendicularly from the blade. This will provide for the sliding plate to scrape debris from any perpendicular surface. A transportation system is provided for enabling the debris to be transported from the sliding plate to an opposite side of the blade for relocating the debris to a more accessible location. Once relocated, this debris will be removed via any conventional removal methods, such as a conventional cleaning apparatus.

The truck bed includes an auxiliary pump for directing fluid outwardly relative to the tank and further includes a drive motor for driving a generator to operate the heater plates, auxiliary pump, and heater unit positioned rearwardly within the truck bed housing with the heater unit underlying an apertured floor of the truck frame plate to direct heat therethrough to effect completion of snow removal underlying the truck body during its traverse over a road surface to be cleared of snow.

Abstract: A snow removal device for a vehicle comprises an elongated casing provided adjacent to and extending along a lower edge section of a window glass and having a snow guide channel therethrough, a snow intake port facing the lower edge section and a pair of snow discharge ports each formed at either end of the snow guide channel. The snow guide channel receives snow entering the snow intake port and guides the snow toward to sides of the vehicle. A transfer device positioned in the snow guide channel moves the snow therein toward the snow discharge ports; and a drive device drives the transfer device, whereby the snow which is wiped from the lower edge section of the window glass by a wiper is removed through the pair of snow discharge ports.

Abstract: A snowblower with a propeller drum seated on a free support axle that is disposed horizontally and perpendicular to the driving direction. The support axle is operated by a drive which is situated centrally within the drum. The snowblower also serves a lateral snowblowing function by the connection of a snowplow in place of the usual second drum. The side of the snowplow adjacent to the propeller drum is fixed rigidly to the housing. The back side of the snowplow is connected to a bushing which can be placed on the support axle normally provided for the removed propeller drum.
