Actuation of the lever arm in relation to the first plate raises or lowers the wheel in relation to the shroud, thereby altering the distance between the shroud and the ground surface. | 09-11-2014 |
| 20160138232 | SNOWTHROWER AND CHUTE ROTATION CONTROL MECHANISM FOR USE WITH SAME - A snowthrower that, in one embodiment, includes a chute rotation control mechanism that permits manual rotation of a directional chute about a chute axis via one-handed input. The mechanism may have a chute rotation lever having a proximal end attached to the directional chute, the lever extending radially from the chute axis to terminate at a distal end, wherein a handle is provided at or near the distal end, the handle having a handle axis parallel to the chute axis. | 05-19-2016 |
| 20160138235 | ROTOR AND ROTOR HOUSING FOR A SNOWTHROWER - A self-propelled snowthrower wherein, in one embodiment, drive members on each side of the snowthrower provide variable speed propulsion. A transmission that delivers power to the drive members may be adapted to de-clutch one of the two drive wheels when the ground speed of that wheel exceeds the driving speed of the transmission. In other embodiments, the snowthrower includes a rotor having a snow ejection surface forming a negative rake angle. Yet other embodiments include a chute rotation control mechanism that permits manual discharge chute rotation via one-handed input. | 05-19-2016 |

| 20090293321 | MOTORIZED SNOWBLOWER CHUTE CONTROL ASSEMBLY AND RELATED METHODS - A chute control assembly and related methods for mounting a motor to a snowblower are disclosed, wherein the motor is capable of being operated to rotate the chute of the snowblower. The motor and a chute bottom holding bracket can be preassembled so that the assembly can then be slipped over the chute gear for final assembly. The motor can receive electrical impulses from the movement of a standard control handle mounted on the snowblower. The electrical impulses can cause the motor to rotate a worm gear or pinion in either direction depending on the movement of the handle. The worm gear or pinion can rotate a gear chute in an appropriate direction, thereby rotating the chute of the snowblower. | 12-03-2009 |
| 20140059899 | Discharge Pipe for Snow Blower - Provided is a discharge pipe for a snow blower, which is mounted on the snow blower, and is capable of easily removing snow covered on an inner wall of a conveyance duct in the process of discharging snow introduced from the snow blower to the outside. | 03-06-2014 |
| 20150128459 | AUTOMATICALLY ADJUSTABLE SNOWTHROWER CHUTE - A snowthrower includes a body, a chute rotatable relative to the body among a plurality of chute positions, wherein the chute is configured to discharge snow from the snowthrower, a motor for rotating the chute, a user input device configured to set a preferred chute bearing, and an electronic control unit configured to control the motor to automatically rotate the chute to an appropriate chute position to maintain the chute at the preferred chute bearing without additional input from the user input device. | 05-14-2015 |
| 20220136194 | DRIVING SYSTEM FOR DRIVING AT LEAST ONE AUGER OF A SNOW REMOVAL DEVICE, A SNOW REMOVAL DEVICE PROVIDED WITH SUCH A DRIVING SYSTEM, A KIT FOR THE INSTALLATION OF SUCH A DRIVING SYSTEM, A METHOD FOR INSTALLING SUCH A DRIVING SYSTEM AND A METHOD FOR THE MANUFACTURE OF COMPONENTS OR PARTS OF THE DRIVING SYSTEM - A driving system for driving at least one auger of a snow removing device comprising at least one at least one self-adjusting chain tensioner. A first portion of the driving system is positioned within an auger housing and a second portion of the driving system is positioned outside the auger housing. The roller chain is adapted to move across a third opening provided in the auger housing. The first portion is covered by a front guard to prevent snow or debris contained in the auger housing to contact said first portion. The front guard is provided with an opening adapted to surround a portion of a shaft element of the auger with a play between periphery of the opening and the periphery of a corresponding portion the shaft element. The play is either small enough to prevent water and or debris to enter the first casing, or filled with a filling element and/or covered with a sealing element secured to the front guard or the corresponding portion of the shaft element of the at least one auger, to have the play small enough to prevent water and/or debris to enter the first casing. The second portion prevent snow or debris present around the snow removing device to contact the said second portion. A snow blower provided with the driving system, a kit comprising parts and/or components of the driving system, a method for assembling the driving system, and a method for manufacturing some components or parts of the driving system. | 05-05-2022 |
