A cutter housing for a lawnmower can include first and second cutting chambers with first and second chamber walls and first/second discharge openings. First and second ring gates that have openings and blocking segments can be concentrically placed within respective first and second chamber walls, and rotatably attached to the cutter housing. The first and second ring gates can be rotated between: (a) an opened position in which the first/second ring gate is positioned with the first/second ring opening having a first overlap with a first/second discharge opening to provide a discharge mode, and (b) a closed position in which the first/second ring gate is positioned with the first/second ring opening having a decreased overlap, relative to the first overlap, with the first/second discharge opening to provide a mulch mode. The ring gates can be stopped at intermediate positions to provide a partial mulch mode or partial discharge mode.

The expanding coupler for a mower and lawn vacuum may pull a suction hose adjacent to a deck adapter outlet. A plurality of hose springs may allow the suction hose to separate from the deck adapter outlet when the suction hose is pulled. The shroud may direct clippings from the deck adapter outlet to the suction hose when the suction hose is separated from the deck adapter outlet. As a non-limiting example, the suction hose may couple a deck adapter of a lawn vacuum to a suction hose adapter of the lawn vacuum. The suction hose may be pulled when the riding lawn mower makes a turn in a direction that is opposite the side that the suction hose is on. Fasteners may prevent the suction hose from separating from the hose adapter.

A rotary lawn mower has one or more grass cutting blades that are rotatable in opposite directions about a vertical axis or axes. Each blade is double edged having front and rear cutting edges on each end of the blade. Each blade end has a front sloped face inboard of the front cutting edge and a rear sloped face inboard of the rear cutting edge. These faces create air flow within the cutting chamber when cutting grass regardless of the direction of rotation of the blade. The direction of rotation of each blade is reversed to switch between discharge and mulching modes of operation. A flow director has a curved vertical guide wall that guides the grass clippings through a discharge opening in the discharge mode and that guides the flow of grass clippings away from the discharge opening in the mulching mode.

A multi-configurable mower deck for use with a lawnmower, the mower deck including a top surface, a front leading edge, at least one side wall extending from the top surface, and at least one partial rear wall extending from the top surface. The mower deck includes both a side-discharge opening formed on one side of the mower deck and a rear-discharge opening formed through the at least one partial rear wall. Additionally, the mower deck may include a selectively removable secondary front baffle configured to block the flow of clippings through the side-discharge opening and direct the flow of clippings toward the rear-discharge opening. The mower deck may also include at least one selectively removable rear baffle, wherein the at least one selectively removable rear baffle is configured to at least partially block the rear-discharge opening.

In a riding-type mower, a vehicle body includes a rear portion in which a pair of right/left vehicle body frames extend in a front-rear direction relative to the vehicle body, with a gap therebetween in a lateral width direction. A mowing device is configured to discharge mown grass rearward relative to the vehicle body such that the mown grass falls onto the ground. A cover is provided in a bottom portion of the vehicle body, at a position that is rearward of the mowing device, and covers a gap between the pair of right/left vehicle body frames.

The disclosed subject matter is directed to a lawnmower that can include a cutter housing with a first chamber wall defining a first cutting chamber. A first discharge opening can be located in the chamber wall, and the cutter housing can include a slot arrangement. A conversion assembly can include an adjustable wall slidably attached to the cutter housing so as to be selectively movable within the slot arrangement between an opened position and a closed position to place the lawnmower in either a discharge mode or a mulch mode (or somewhere in between).

An agricultural apparatus for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field, which may comprise: a frame, crop engaging elements supported on the frame and configured to form from previously-cut agricultural crop a windrow on a field, and a control unit configured to control operation of the crop engaging elements. The control unit is further configured to provide control signals to the crop engaging elements in such a way that, in a windrow forming mode of operation, the crop engaging elements are driven to engage with the previously-cut agricultural crop, and form from the previously-cut agricultural crop the windrow which may have a snake line form on the field. Further detailed is a method for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field.

A harvesting header has a set of centrally disposed conditioner rolls comprising conditioning structure to condition crop and a rotary cutter bed. The rotary cutter bed has a plurality of rotary cutters extending across the path of travel of the header to define a cutting plane, each cutter being rotatable about an upright axis, the conditioner rolls being behind the cutter bed to condition crop cut by the rotary cutter bed. The header has a crop-directing header windguard configured to direct the crop down towards the conditioning rolls after the plurality of cutters have severed the crop, the header windguard extending in a rearwardly direction from a position forward of the cutter bed to a position proximate the conditioner rolls, and the header windguard extending transversely at least a width of the rotary cutter bed.

A mower deck insert includes a first cutting chamber, a second cutting chamber, and a discharge passage extending adjacent to the first cutting chamber and the second cutting chamber. The first cutting chamber includes a first axial scroll extending about a first vertical axis. The first axial scroll includes a first upper surface having a first start region and a first end region. The second cutting chamber includes a second axial scroll extending about a second vertical axis. The second axial scroll includes a second upper surface having a second start region and a second end region. The first start region is vertically lower than the first end region, and the second start region is vertically lower than the second end region.

In a riding-type mower, a vehicle body includes a rear portion in which a pair of right/left vehicle body frames extend in a front-rear direction relative to the vehicle body, with a gap therebetween in a lateral width direction. A mowing device is configured to discharge mown grass rearward relative to the vehicle body such that the mown grass falls onto the ground. A cover is provided in a bottom portion of the vehicle body, at a position that is rearward of the mowing device, and covers a gap between the pair of right/left vehicle body frames.
