Abstract: A bi-directional drive system for turf grooming and brushing operations includes a first gear rotatably connected to a reel deck assembly. A reel shaft gear is connected to a reel shaft and rotated in a first axial rotation direction. Second and third gears are rotatably connected to the reel deck assembly. A double sided cogged belt is engaged to the reel shaft gear. An attachment member defining a turf component is rotated in the first axial rotational direction by rotation of the reel shaft gear connected to the first gear by the double sided cogged belt without rotation of the second and third gears. The turf component as a turf groomer is rotated in a second axial rotational direction opposite to the first axial rotational direction by rotation of the reel shaft gear connected to the first, second and third gears by the double sided cogged belt.

The grass treatment insert has a shaft with ball bearings on opposite ends which are housed within a bearing housing. A handle is provided on the bearing housing for lifting the grass treatment insert.

Abstract: A cutting device for crop has a cutting tool which can be set into rotation, and a shear bar which can be displaced relative thereto, each of the two diametrically opposed ends of which is coupled to a control unit, thereby enabling the clearance position of the shear bar relative to the cutting tool to be changed, and a control device which activates the control units in order to change the clearance position of the shear bar, and to move the shear bar toward the cutting tool, the control device can be operated to activate the control units to each perform a working step in alternation, so that within this working step the particular activated control unit initially moves the end of the shear bar assigned thereto toward the cutting tool by a first adjusting distance, and then away from the cutting tool by a second adjusting distance, wherein the second adjusting distance is smaller than the first adjusting distance.

Abstract: A grass treatment unit with an adjustable hood for use with various grass treatment inserts of different diameter for verticutting, scarifying, etc. The grass treatment unit includes a frame with sidewalls mounted on front and rear rollers. An open topped bearing socket is attached to each of the sidewalls for mounting the grass treatment insert for rotation. A hood mounted on a slide for spacing the hood in a selected position with respect to the grass treatment insert. Spring plungers are provided for locking the grass treatment insert in the bearing sockets and for locking the slide in a selected position on the sidewalls. The grass treatment insert has a shaft with ball bearings on opposite ends which are housed within a bearing housing. A handle is provided on the bearing housing for lifting the grass treatment insert.

Abstract: Apparatus for treating grass comprising a grass treatment unit 200 configured to be affixed to a grass treatment machine; a cassette 206, the cassette 206 comprising a grass treatment device 207 configured to rotate in response to a rotation of a drive shaft, the drive shaft being connected to a motor located at the grass treatment machine, the grass treatment unit 200 comprising means 211 to releasably mount the cassette 206 on the grass treatment unit 200, wherein the grass treatment device 207 is selected from a set of grass treatment devices, the set including a vibration drum.

Abstract: An auxiliary drive mounted to a reel mower cutting unit includes an auxiliary drive input shaft engageable to a cutting reel shaft of the reel mower cutting unit. The auxiliary drive transmits rotational power to an attachment rotatably mounted to the reel mower cutting unit. The auxiliary drive has a housing with a flange positionable on a boss concentric with the cutting reel shaft. A plurality of holes extend through the flange, and a circumferential groove extends at least partially around the boss. A retaining clip is inserted through the holes in the flange and into the circumferential groove to axially retain the auxiliary drive housing to the boss while allowing the auxiliary drive housing to pivot on the cutting reel shaft.

Abstract: A rotary cutter for a mower for mowing grass and the like with a cord of a desired length extending in a radial direction of a cutting head from the cutting head driven for rotation through a drive shaft is described. The rotary cutter includes at least one fastening element for fixing one end of the cord to a cutting head main body. An inner end portion of the cord inserted from a sidewall of the head main body is fastened by the fastening element. The cord is removed and replaced with a new cord when the cord is worn out. The cord fastening element is disposed near a drive shaft coupling shaft tube portion in the cutting head main body. A cord outlet for removing the cord is provided to the drive shaft coupling shaft tube portion side. The inner end portion of the cord extends outside from the cord outlet and along a sidewall of the drive shaft coupling shaft tube portion of the cutting head main body.

Abstract: A novel soil conditioning rotary reel comprised of a rotary reel having a plurality of flat bars attached to support plates in a symmetrical helix arrangement is disclosed. The number of bars and the diameter of the reel are determined by the limitation that the straight-line distance between two adjacent bars be less than six inches.

Abstract: This is a large rotatable cutter head primarily useful in masticating vegetation ranging from grasses to large trees. The inventive cutter head is typically mounted on an articulating arm on a tractor or tread-based vehicle. Depending upon the size of the arm and its maneuverability, the cutter head may be used to cut and grind vegetation variously from the ground surface to many feet off the ground. The rotatable cutter head assembly includes a number of rotating cutters mounted inside the periphery of the assembled drum and that spin freely outside the diameter of that drum and, upon contact with vegetation, rotate into the drum assembly. The invention includes combinations of the cutter head with the support vehicle or articulating arm and methods of using the cutter head.

Abstract: Implements for attaching to a hand-held, powered “Weed-Eater” type device to perform various work or chores (filament cutting, blade cutting, brushing, blowing, mixing, etc.). After disconnecting the device's original implement typically a spool of filament (6) with a bumper feed (7), an initial, cultivator/cutter implement (10), cylindrical in shape with a substantially solid, circular top (12) and a relatively thin, continuous wall of constant thickness, is attached by an appropriate threaded member (e.g. a nut or bolt, usually with one or more washers) to the bottom end of the powered device (FIGS. 1A-D) through a central opening (13). The cultivator's top includes a series of circumferentially spaced, “snap-in” openings (14; e.g. two or more) through and into which other implements (e.g. those of FIGS. 3-20) can be attached (FIGS.
