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 mowing system includes: a driving vehicle having a steerable axle and a pivotable tongue and defining a travel axis; a first mower coupled to the driving vehicle; a second mower coupled to the tongue; a tongue actuator configured to pivot the tongue; a tongue angle sensor configured to output signals corresponding to a tongue angle of the tongue; and a controller operatively coupled to the tongue actuator and the tongue angle sensor. The controller is configured to: determine a lateral overlap or underlap of the mowers exceeds a threshold value based at least partially on the tongue angle and a steering angle of the steerable axle; determine a correction angle needed for the tongue to pivot such that the lateral overlap or underlap no longer exceeds the threshold value; and output a correction signal to the tongue actuator to pivot the tongue by the correction angle.

A system and method according to one embodiment are provided in a vehicle to perform a two-stage cut of grass or other vegetation in a field or lawn. The first stage may be a coarse cut stage, and the second stage may be a finish cut stage. The first and second stages may be conducted by separate cutting configurations. For instance, the first cutting configuration or coarse cutting configuration may be a flail mower configuration, and the second cutting configuration or finish cutting configuration may be a rotary cutting configuration.

A crop windrow monitoring system includes an image sensor positioned to include a field of view facing a rearward direction of a power unit, and a visual monitor operable to display an image. A computing device is operable to determine an intended direction of movement of the power unit. The image is displayed on the visual monitor in a first mode having a first magnification when the intended direction of movement includes the rearward direction. The image is displayed on the visual monitor in a second mode having a second magnification and overlaid with indicia indicating a width of the windrow when the intended direction of movement includes the forward direction. The second magnification may be larger than the first magnification.

Various embodiments of a cutting deck assembly and a grounds maintenance vehicle that includes such assembly are disclosed. The assembly includes a top surface and a sidewall extending from the top surface. The top surface and the sidewall partially surround a first cutting chamber and a second cutting chamber. The assembly further includes a channel disposed adjacent a rear portion of the sidewall and extending along a channel axis between a first end and a second end of the channel, where the first end of the channel is connected to an outlet of the first cutting chamber; and a ramp disposed at least partially within the channel and adjacent the second end of the channel. The ramp includes a directing surface that is adapted to deflect at least a portion of clippings that enter the channel from the outlet of the first cutting chamber.

A grass mower includes a blade shaft for rotating a blade within a mower deck supported to a vehicle body, a power transmission mechanism for supplying rotational power to the blade shaft, a duct for air-conveying cut grass pieces from the mower deck to the grass collecting bag and a flow boosting device incorporated in the duct. The flow boosting device increases a speed of air flow inside the duct by feeding air through a nozzle opening adjacent an inner circumferential face of the duct along a flow direction of the air flow.

A header includes: a header frame; a cutter carried by the header frame; a roll disposed rearwardly of the cutter and configured to convey cut crop material rearwardly in a crop flow stream; a swath gate coupled to the header frame and movable between a spreading position and a converging position; a spreader coupled to the swath gate and configured to laterally spread the crop flow stream as the crop flow stream flows across the spreader; and a converger coupled to the swath gate and configured to converge the crop flow stream toward a centerline of the swath gate as the crop flow stream flows across the converger. The spreader and the converger are configured to not be in the crop flow stream at the same time, depending on the position of the swath gate.

Mower unit mountable to a traveling vehicle body and being configured to suppress generation of turbulence. The mower includes a mower deck, a plurality of blades, a rear vacuum plate that includes a plurality of arcuate portions and a convexly curved portion curved to extend into a triangular gap portion formed between two adjacent rotational locus circles. The convex curved portion bridges opposed ends of two adjacent arcuate portions at two inflection points (IP) of the rear vacuum plate. The triangular gap is defined by a distance (S) between the two inflection points (IP) and a top point (TP) located at a distance (L) from a reference straight line connecting center points of the two adjacent rotational locus circles.

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.

A harvesting apparatus includes a crop conditioning element and an associated hood for conditioning crop material. The hood is moveably mounted to a frame of the harvesting apparatus, at a position located above the crop conditioning element. The hood is moveably mounted to the frame for movement toward and away from the crop conditioning element to adjust a gap therebetween. A swathboard is attached to and moveable with the hood. The swathboard is moveable relative to the hood between a plurality of operating positions. The swathboard is operable to maintain its position relative to the hood during movement with the hood toward and away from the crop conditioning element to form a consistent swath while moving the hood relative to the crop conditioning element to adjust the gap therebetween.
