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.

A converging drum for a crop mowing implement includes a body that extends along a central longitudinal axis. The body rotates about the central longitudinal axis in a defined rotational direction. At least one ramp feature extends radially outward from the body, relative to the central longitudinal axis. The ramp feature is arranged to form an acute angle relative to a reference plane. The acute angle may open toward the defined rotational direction to move cut crop downward, or the acute angle may open away from the defined rotational direction to move crop upward, to position the cut crop for a conditioning system. The converging drum may include a first group of ramp features near a second end of the body for moving cut crop downward, and/or a second group of ramp features near a first end of the body for moving cut crop upward.

In a rotary mower having ten generally horizontal cutter disks forming a total cutting length along the cutter bar of 16 feet, the discharge opening containing the parallel conditioner rolls and a parallel transfer roll has a width of at least 125 inches. This allows a first outermost one of the ten disks and approximately one half of the next adjacent disk to be mounted on the cutter bar outwardly of the discharge opening. A convergence system then includes only first and second impellers with the first impeller mounted on the first disk for rotation therewith and the second impeller mounted on an upper support above the impeller so that the second impeller hangs downwardly toward the second disk for contacting the cut crop and mounted immediately adjacent with the second impeller having a peripheral edge located at or immediately adjacent the vertical plane of the side of the discharge opening.

Various types of lawnmowers are disclosed that include at least one cutter housing having a chamber wall with a discharge opening therein. The mowers can include a rolling shutter formed of multiple steel sheets held together by pins. In discharge mode, the rolling shutter can be wrapped around a roller cylinder. In mulching mode the rolling shutter can extend to close off the discharge opening of the mower.

A conveyor joint assembly (600) is provided including a support ledge (501) operably coupled to and extending from a first sealing surface (602), a first side wall and second side wall (507) operably coupled to opposite ends of the support ledge (501), a receiver (504) operably coupled to the first sealing surface (602), and at least one protrusion (503) operably coupled to a second sealing surface (604). The second sealing surface (604) is configured to engage the support ledge (501) and the receiver (504) is configured to retain the at least one protrusion (503) causing the first sealing surface (602) to engage the second sealing surface (604).

A system having a frame, an auger operably coupled to the frame, an auger wrapper fixed to the frame and proximal to the auger, the auger wrapper having a curved surface with a first rigidity, and a liner attached to the auger wrapper, the liner comprising a second rigidity that is less rigid than the first rigidity.

A riding vehicle may include a blower assembly, a mower deck, and a power source. The blower assembly may be configured to direct air from an air inlet to at least one air outlet to move surface debris. The mower deck may be configured to cut a lawn formed of grass or other vegetation. The blower assembly may be configured to direct air to an interior space of the mower deck for assisted discharge of cuttings.

A lawn mower includes a mower device provided between a pair of right and left front wheels and a pair of right and left rear wheels and configured to mow grass on a traveling land surface; a grass collecting container provided rearwardly of a vehicle body, a conveyer duct extending between the mower device and the grass collecting container as extending through between the pair of right and left rear wheels and configured to convey grass clippings discharged from the mower device to the grass collecting container; and a belt conveyer configured to convey the grass clippings discharged from the mower device toward the grass collecting container. The belt conveyer forms a conveying bottom face of the conveyer duct.
