Patent number: 11140821Abstract: A lawnmower and lawnmower cooling system can include a housing configured to contain a motor, a battery assembly, a motor driver, and a controller. The housing can include at least one air inlet located adjacent to the top surface of the deck. The housing can include a driver chamber, a battery chamber, a motor chamber, and at least one air outlet. A fan can be mounted in the housing such that, when the fan operates, air enters the air inlet, flows through the driver chamber away from the top surface of the deck along the upward direction, passes through the motor driver along the upward direction, passes into the battery chamber and flows through the battery pack, passes into the motor chamber and flows through the electric motor, and exits the motor chamber through the at least one air outlet.Type: GrantFiled: March 14, 2019Date of Patent: October 12, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Toshiyuki Hasegawa, Shivang Desai, Robert A.

Patent number: 10945366Abstract: Various types of lawnmowers are disclosed that include a cutter housing having a cutting chamber and a discharge opening therein. A driving mechanism can be mounted on the cutter housing, and a radius arm can be mounted on or near the blade spindle such that the radius arm is rotatable about the blade spindle. A shutter gate that is arcuate in shape can be mounted on the radius arm so as to rotate with the radius arm between a discharge arrangement and a mulch arrangement. The shutter gate can include a driven element that is driven by the driving mechanism to cause the shutter gate to rotate between the discharge arrangement where the shutter gate allows for discharge of vegetation through the discharge opening, and the mulch arrangement where the shutter gate blocks the discharge opening.Type: GrantFiled: March 12, 2019Date of Patent: March 16, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Shivang Desai, Christopher Todd Walker

Patent number: 10897845Abstract: Various types of lawnmowers are disclosed that include a cutter housing having a chamber wall and a discharge opening therein. A mulch gate can be provided with an interior scroll-shaped face and can be pivotably attached to the cutter housing so as to be movable between an opened gate position and a closed position. In the opened position, the mulch gate is positioned such that the discharge opening is opened to an exterior of the lawnmower to allow clippings to pass therethrough and out of the lawnmower. In the closed position the mulch gate closes the discharge opening to provide a mulch mode in which clippings remain in the cutter housing for added cutting by the lawnmower blade. When the mulch gate is in the closed gate position, the interior scroll-shaped face of the mulch gate can be substantially continuous with a wall interior surface of the chamber wall.Type: GrantFiled: January 28, 2019Date of Patent: January 26, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Christopher Todd Walker, Robert A.

Patent number: 10834869Abstract: According to an embodiment of the disclosed subject matter, a lift assembly for a lawnmower can include a mower housing configured to house blades for cutting vegetation. A frame can be located above the mower housing, the frame including two longitudinal extending frame members, and at least one pivot bar extending between the two longitudinal extending frame members. A linear actuator can be located adjacent the frame members and connected to the pivot bar such that actuation of the linear actuator causes the pivot bar to rotate about a rotational axis of the pivot bar. At least one cam can be connected to the pivot bar so as to rotate with the pivot bar, the cam including a mower housing attachment element that supports the mower housing such that rotation of the cam varies a distance between the frame and the mower housing.Type: GrantFiled: February 20, 2019Date of Patent: November 17, 2020Assignee: HONDA MOTOR CO., LTD.Inventor: Christopher Todd Walker

Patent number: 7703223Abstract: 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.Type: GrantFiled: May 29, 2008Date of Patent: April 27, 2010Assignee: Honda Motor Co., Ltd.Inventors: Christopher Todd Walker, Scott J.
