A rotary cutting implement includes a housing that extends along a longitudinal axis. The rotary cutting implement also includes an annular wall coupled to the housing to define a cutting chamber having a width defined from a first sidewall to a second sidewall. The annular wall includes a distribution deflector having a body that extends along an axis substantially transverse to the longitudinal axis to form the second sidewall of the cutting chamber. The distribution deflector distributes cut residue over substantially the width of the cutting chamber.

A stalk roll mountable to a header of an agricultural combine for rotation about a rotation axis during processing of plant stalks has an annular drum with detachable blades. The stack roll has a plurality of circumferentially spaced flutes extending in an axial direction of the rotation axis of the drum and projecting radially outwardly from the drum. The flutes define mounting surfaces along lengths of the flutes. A plurality of blades are attachable to the drum with multiple of the plurality of blades being attachable to the mounting surface of a common one of the flutes. Mounting hardware is configured to removably connect the blades to the mounting surfaces of the flutes.

A reducing element system includes a reducing element having a main body defining a fastener opening, a leading face defined by the main body, and a trailing face defined by the main body. The trailing face includes a pair of mating features equally spaced from the fastener opening and having a generally arcuate cross-section perpendicular to a fastener axis. The system further includes a reducing element mount having a main body defining a fastener opening, a leading face defined by the main body, and a reducing element mount mating feature defined by the leading face. The mount mating feature has a generally arcuate cross-section perpendicular to the fastener axis. The reducing element mount mating feature of the reducing element mount is configured to mate with at least one of the mating features of the reducing element when the reducing element mount is mated with the reducing element.

A lawnmower with a plurality of blade holding elements in a horizontally rotating blade assembly holds a plurality of blades in a blade channel. The blade assembly is covered by a blade assembly guard that is only open underneath at a point where blades in the blade assembly would cut grass during normal operation. A blade assembly access panel in the upper portion of the blade assembly guard allows blades or a blade assembly to be easily replaced.

A plant vine chopper rotor drum assembly has a plurality of rotor rings spaced along, encircling, and attached to the longitudinal outer surface of a rotatable main drum tube. Each rotor ring has one or more pairs of angled mounting tabs that alternate to the left and to the right to the general plane of respective rotor ring; and the rotor rings are distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each mounting tab having a generally planar cutting blade attached. The angled blades distributed around the outer circumference of the ring cooperate one with another during operational rotation of the drum to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum.

A blade cartridge for a horizontal rotary mower includes airfoil blades and diverter blades that alter airflow within the blade cartridge and prevent grass clippings from accumulating. The horizontal rotary lawnmower may be adapted to engage a cleaning station with brushes or cleaning pads to remove grass clippings while the horizontal rotary lawnmower blade assembly is operated in reverse. The cleaning station may automatically engage a reverse operation. The cleaning station may also hone the blades of the blade assembly while operating in reverse.

An apparatus for surface treatment and collection of undesirable debris from lawns. During a cutting operation, rotating blades ripe surface material from soil up onto a filtering screen and along this further to a collecting box so that only stones and debris of e.g. at least 1 cm enter the box whereas smaller particles/soil escape through the filter screen and are thereby returned to the lawn surface, which significantly increases the nutrient level in the upper layers of the lawn.
