摘要： A riding lawnmower vehicle includes two main drive wheels, at least one caster wheel, an electric traction motor, an internal combustion engine, a generator driven by the internal combustion engine, and a lawnmower. The electric energy generated by the generator can be supplied directly or via an electric accumulator to the electric traction motor. The main drive wheels are independently driven by the electric traction motor, which can operate as a traction power source. When viewed from one end to the other end in the width direction of the vehicle, the internal combustion engine and a secondary battery operable as the electric accumulator overlap each other, and the main drive wheels overlap at least a part of at least one of the internal combustion engine, the generator, the secondary battery, a fuel cell, a capacitor, an inverter, a cooling device, a mower driving motor, and a grass-collecting duct.

摘要： A reel mower cutting unit (100) having a cutting reel (112) with a horizontal axis is supported by a front roller (102) and a rear roller (104) in a mowing position. A lift arm may raise and lower the cutting reel (112) between a mowing position and a transport position. A pair of gauge wheels (116) is mounted forwardly of the front roller (102) at a front left corner and a right front corner of the unit (100). If the unit (100) is lowered to a sloped surface, the gauge wheel (116) contacts the surface and prevents the unit (100) from marking or damaging the turf.

摘要： A reel mower has a double A arm suspension that lowers a reel cutting unit into a cutting position in a tail down orientation and that levels the reel cutting unit out as it lifts the reel cutting unit into a transport position. The reel cutting unit yaws during turns about a substantially vertical axis having a negative caster angle. The suspension has clamps that can be flipped open or closed to quickly attach or detach the reel cutting unit. A drive motor can be quickly attached or detached to the reel cutting unit using a pivotal wire form. An active counterbalance system automatically offsets the increasing weight of a grass basket on the reel cutting unit to maintain quality of cut. The grass basket maintains a constant spacing relative to the reel cutting unit when the reel cutting unit pitches to improve clipping collection.

摘要： A roller configuration for a grass mowing machine (100) is provided to reduce roller overlap marks. The roller configuration may be used on a grass mowing machine (100) having a first row of cutting units (102-104) and a second row of cutting units (105-106). Each cutting unit (102-104,105-106) has a roller (126-130,132-136) with a reduced diameter portion (137,138,147,148) adjacent a full diameter end portion (139,140,149,150). The full diameter end portions (139,140,149,150) of the rollers (126-130,132-136) on the first row of cutting units (102-104) are aligned with the reduced diameter portions (137,138,147,148) of the rollers (126-130,132-136) on the second row of cutting units (105-106) during mowing operations, and the reduced diameter portions (137,138,147,148) of the rollers (126-130,132-136) on the first row of cutting units (102-104) aligned with the full diameter end portions (139,140,149,150) of the rollers (126-130,132-136) on the second row of cutting units during (105-106) mowing operations.

摘要： A traction enhancement system (12) and method of using the same for use with a turf mower (10) having a vehicle frame (14), a first drive wheel (20) operably mounted to the vehicle frame, and a cutting unit (28) positionable in a first position, where the cutting unit is supported by ground engaging rollers (42), and a second position, where the cutting unit is supported by the vehicle frame. The traction system is then operably coupled between the cutting unit and the vehicle frame such that the traction system can modulate the cutting unit between the first position and the second position for improved traction of the first drive wheel.

摘要： A grass cutting machine has two forward cutting units (24) and one rear central unit (46). The mechanism (36, 48) for lifting and lowering the cutting units at, for example, the margin of a golf green, provides a time delay between lifting or lowering of the front (24) and rear cutting units (46) which is determined by the distance travelled by the machine. In this way it is ensured that all units start and stop cutting at the same reference point on the ground.

摘要： A mower includes a plurality of cutting heads, each cutting head having a minor cutting width, the plurality of cutting heads connected by a plurality of connectors in an array having a variable major cutting width. The mower also includes a steering system coupled with a first driven wheel and supported by one cutting head, and a second driven wheel supported by one other cutting head. The steering system is capable of steering the first driven wheel independently from the second driven wheel.

摘要： A reel mower has a traction frame which carries one or more reel cutting units. Each cutting unit has a grass basket associated therewith for receiving and collecting grass clippings generated by operation of the cutting unit. Each grass basket has a forward portion of a bottom wall thereof formed by a piece of flexible material. An actuator is operatively engaged with the flexible material piece for lifting a front end of the flexible material piece upwardly relative to a rear end of the flexible material piece in response to changes in orientation between the cutting unit and the grass basket during operation of the mower to incline the flexible material piece and thereby promote the flow of grass clippings down the so inclined flexible material piece to more fully fill the grass basket.

摘要： A stalk roll assembly for header of a combine harvester. The assembly includes first and second stalk rolls spaced laterally with respect to one another and rotating in opposite directions. Each stalk roll includes a frusto-conical nose and a cylindrical body. The cylindrical body includes a plurality of radially extending flutes. The nose includes a pair of helical flights. The plurality of flutes includes at least one cutting flute having a straight edge and a plurality of puncturing flutes with teeth. The stalk rolls are laterally offset a distance that permits the tips of the flutes to laterally overlap and the teeth of the puncturing flutes are longitudinally offset so the tips of the teeth are received between with the valleys of the teeth of the other stalk roll.
