A stalk roll having twelve flutes extending radially from the main cylinder along the length of the main cylinder. Within the row unit opposing stalk rolls cooperate to engage and capture the corn stalk, thereafter, controlling and processing the corn stalk. The flutes may be configured with differing edges to facilitate control and movement of the stalk to the point of ear separation within the row unit. The flutes may be configured such that opposing compressive forces acting on the exterior of the stalk at approximately 180 of separation operate to implode the stalk while sharp edges on the flutes operate to cut the stalk into small segments which are deposited on the ground for decomposition.

A wide area turf mower (10) has a wheel supported main frame (12) and cutting units (22, 24, 26, 28, 30, 32, 34) movably connected to the main frame (12) and positioned in rows (36, 38, 40) in a staggered order to form a mower cutting configuration for cutting a continuous swath of turf between any two outer cutting units (26, 32) located respectively on opposite sides of the main frame (12). One row (38) of the cutting units comprises a first pair of interconnected outer and inner cutting units (26, 28) at a first side (18) of the main frame (12) and a second pair of interconnected inner and outer cutting units (30, 32) at the second side (20) of the main frame (12). The inner cutting units (28, 30) are pivotally connected to the main frame and the outer cutting units (26, 32) are pivotally connected to a respective inner cutting unit (28, 30). Hydraulic cylinders (42, 44) cause the outer cutting units (26, 32) to fold in a direction towards the rear end of the main frame (12). Hydraulic cylinders (50, 52) cause the inner cutting units (28, 30) to lift in an upward direction. A controller operates all of the hydraulic cylinders.

An apparatus for mowing grass. The apparatus has a plurality of cutting devices for mowing the grass. The apparatus has a plurality of carrying arms which are arranged offset with respect to one another with regard to the transverse axis of the apparatus, and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices. The apparatus has a plurality of supporting elements which support in each case one of the plurality of carrying arms on an underlying surface, and are arranged in front of the respective cutting device with regard to a forward moving direction of the apparatus. The apparatus can have the advantage that the leading supporting elements do not push any cuttings in front of them, and a risk of the apparatus being jacked up is decreased.

A vegetation chopping roller for an agricultural land roller implement including a drum body having an outer periphery which is generally cylindrical about a drum axis of rotation and a plurality of protruding mounting flanges upon which chopping blades are mounted using threaded fasteners. A seating surface is fixedly supported in relation to the drum body in association with each blade which receives the inner edge of the associated blade abutted thereon such that the threaded fasteners are substantially isolated from shear forces by the abutment of the blades with the seating surfaces.

A lawnmower uses thin, replaceable blades with a hardened cutting edge and a cross-section defining an airfoil retained in cartridges that are inserted and removed from rotors in a blade assembly at need. The cartridges comprise a blade and rotor interlocking elements affixed to the blade, each rotor interlocking element corresponding to one rotor in the blade assembly. Each rotor and rotor interlocking element includes features that allow the two to be securely engages so that the rotors may be spun quickly in a mower blade assembly to cut grass.

A system for controlling a grass cutting reel assembly of a turf-care vehicle. The system includes: a reel cylinder motor operable to rotate a reel cylinder of a grass cutting reel assembly of a turf-care vehicle at a desired rotational rate of speed to provide a controllable frequency of clip for the reel assembly; an automated height of cut control system operable to control a position of a front roller of the reel assembly to provide a controllable height of cut for the reel assembly; and a controller system operable to control the reel cylinder motor and the height of cut control system to provide a particular frequency of clip and a particular height of cut stipulated by one of a plurality of cutting scenarios programmed into the controller system and selected via a user interface of the controller system that is accessible by an operator onboard the turf-care vehicle.

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.
