Definitions

  • the present invention relates to a mower, and in particular a flail mower.
  • Mowers are used to cut grass, weeds, and other plants.
  • These mowers may either be integral to a vehicle, or an attachment configured to be secured to a vehicle.
  • the vehicles are generally agricultural vehicles such as tractors.
  • Flail mowers are a particularly important mower due to their versatility.
  • a flail mower is formed from a substantially horizontal axle mounted within a housing. Mowing blades are suspended from the substantially horizontal axle. A drive system controls rotation of the axle. Centrifugal force causes the mowing blades to be thrown away from the axle.
  • the mowing blades generally have a flat or curved cross sectional shape, or a T / Y shape. This provides a large cutting area per blade.
  • Blades are offset from each other to ensure that cutting efficiency is improved and that areas of ground are not missed as a mower moves forward. This accounts for differences in the forward movement of the mower and the rotation of the substantially horizontal axle.
  • Flail decks for cutting short plant matter have a housing which extends substantially the ground. The housing acts to prevent cut matter and debris from being thrown away from the mower.
  • the shape of the housing facilitates rotation of the axle and blades creating air currents in the housing, and around the axle. Such air movement lifts plant material up, ensuring that it can be properly cut.
  • mowers for cutting long grass and stalky plant material have a plurality of flaps which are pivotally mounted across a channel in the housing.
  • the flail deck mower moves forward. Plants to be cut abut the flaps.
  • the flaps pivot allowing the plants into the housing. The pivoting action of the flaps helps to ensure that plant matter is not bent over, which would limit efficiency of the cutting..
  • a problem of this type of mower is that the channel limits the creation of air movement to lift short grass into a position at which it can be cut. Therefore flail mowers with moveable flaps are less efficient at cutting short length plant matter.

  • a mower including
  • a housing providing a cavity
  • a drive system configured to control operation of the mowing assembly
  • the present invention relates to a flail mowing attachment configured for connection to a vehicle.
  • the present invention may be a mower integral to a vehicle, or a flail mower incorporated into a tractor or ride-on.
  • housing should be understood as meaning a body to which the components of the mower may be mounted.
  • the housing provides a cavity within which the components of the mower are mounted.
  • the cavity is open to ground below the mower in use, thereby allowing the mowing blades to cut plant material.
  • the housing prevents debris from being thrown away from the mower by action of the blades. This should become clearer from the following description.
  • the bottom edges of the housing may be substantially near the ground over which the mower may be used. This helps to prevent cut material or debris being thrown away from the mower in-use as the housing provides.
  • the housing may have at least one wheel mounted thereon to support the mower.
  • the housing may also have rollers, skids at either side of the housing, or two or more wheels to help support the mower.
  • the housing may have an attachment assembly.
  • attachment assembly should be understood as meaning one or more components which can secure the flail mowing attachment to a vehicle.
  • the mowing attachment may be secured to a tractor using a two point linkage if the mower is front mounted or a three point linkage if rear mounted.
  • channel should be understood as meaning an opening into or through which an object can be directed.
  • the channel may be an opening in a wall, or between walls, of the housing and into the cavity.
  • the channel may be open to the ground below the mower. In other words, the channel is not bounded at its bottom edge meaning there are no obstructions between the channel and the ground below.
  • This embodiment allows the mower to pass over plant material being cut while substantially decreasing disturbance of the material which may be caused by contact with the housing were the channel not present. This should become clearer from the following description.
  • the channel may be forward facing and at the forward most part of the housing in the mower's direction of movement in-use.
  • the mowing blades may be a flail mowing assembly.
  • the flail mowing assembly may be a substantially horizontal axle moveably mounted inside the housing.
  • the mowing blades may be secured to the substantially horizontal axle.
  • rotation of the substantially horizontal axle causes the mowing blades to rotate around the axle.
  • the centrifugal force created by rotation of the axle causes the mowing blades to be forced outwards.
  • drive system should be understood as meaning an assembly to control operation of the mowing assembly and to rotate the mowing blades.
  • the drive system may be a belt drive connected to a gear box.
  • the gear box may be connected to a drive shaft on a work vehicle or tractor. This is as should be understood by one skilled in the art.
  • the mower may also include a power take off coupling configured to engage with a work vehicle or tractor. This is as should be known to those skilled in the art.
  • first and second cutting configurations should be understood as referring to different configurations of the mower for cutting plant matter of different length from the ground.
  • moving the mower between the first and second configurations does not involve changing the height of mowing blades or a mowing assembly.
  • the first cutting configuration may have a barrier element in a storage position.
  • the barrier element does not block the channel and does not prevent the flaps pivoting.
  • the second cutting configuration may have a barrier element in an operative position. In this position the barrier element may block a substantial portion of the channel. This is beneficial as the barrier element provides a rigid barrier to substantially cover the channel. This assists movement of the mowing blades in generating air currents with the housing. These currents assist in lifting plant matter to ensure that this is cut by the mowing blades.
  • barrier element should be understood as meaning a component which can block all or a substantial part of the channel.
  • the barrier element is able to block and provide a rigid barrier across the channel.
  • this barrier elements extends substantially to the bottom edges of the housing. In a preferred embodiment the barrier element may extend to within 25 - 50 mm of the bottom of an arc outlined by the mowing blades when rotating in use.
  • the barrier element may be pivotally attached to the housing. Therefore, the barrier may be pivoted to define the first cutting configuration and the second cutting configuration.
  • the barrier element may be manually moved by a person.
  • the mower may include a lever or an actuator such as a hydraulic cylinder or electric actuator. These can move the barrier element with respect to the housing and thereby move the mower between the first and second configurations.
  • a locking mechanism can be used to secure the barrier element with respect to the housing and therefore in the first or second configurations.

  • Figure 6 is the view of Figure 5 with the mowing attachment in the second cutting configuration.
  • the mowing attachment (1) has a housing (2) with side walls (3, 4) and a back wall (5).
  • a channel (6) is defined by the space between the side walls (3, 4).
  • Flaps (7) are pivotally mounted to the housing (2). The pivotable mounting of the flaps (7) allows them to swing easily and independently of each other.
  • the flaps (7) extend across the channel (6).
  • the flaps (7) have a length so that they extend to bottom edge (8) of the side walls (3, 4).
  • the side walls (3, 4), back wall (5), and channel (6) define a cavity generally indicated as (9).
  • a flail mowing assembly (10) is secured inside the cavity (9).
  • the flail mowing assembly (10) is formed from a substantially horizontal axle (11) rotatably mounted within the housing (2).
  • Flail mowing blades (12) are mounted on the substantially horizontal axle (11).
  • the mounting of the mowing blades (12) is such that they can pivot freely relative to the axle (11). This is as should be known by those skilled in the art.
  • a drive system is attached to the axle (11) to control its rotation.
  • the drive system is a belt (not shown) driven by a right angled gear box (not shown).
  • the gear box is powered by a power take off from a tractor (not shown) to which the mowing attachment (1) may be secured.
  • a barrier element (13) is mounted on an axle (14) which is itself secured to the housing (2).
  • the barrier element (13) is moveable between a first cutting configuration as shown in Figures 1 , 3, and 5, and a second cutting configuration as shown in Figures 2, 4, and 6.
  • the nut is moved causing the barrier element to rotate about axle (14). Movement of the nut (15) is guided by a track (16). Once the nut (15) reaches point (17A) the nut (15) is tightened to secure the barrier element (13) with respect to the housing (2). This is the first configuration of the mower.
  • the barrier element (13) is retracted out of, and away from, the channel (6). This means that the barrier element (13) does not abut long plant matter as the mower moves forward in use. Rather, the plant matter can abut the flaps (7).
  • the flaps (7) pivot to allow the plant matter into the cavity (9) without being substantially deformed or bent over.
  • the nut (15) can be loosened and then moved along the track (16) to point (17B). The nut is tightened to secure the barrier element (13). This is the second cutting configuration.
  • the barrier element (13) is across the channel (6). Therefore the barrier element (13) provides a rigid barrier across the channel. Note that in the second configuration the flaps (7) are maintained in the same position with respect to the housing (2) and channel (6) as in the first configuration.
  • the barrier element (13) blocks the channel (6) and substantially extends to the bottom edge (8) of the side walls (3, 4).
  • the barrier element (13) is moved to define the first or second cutting configurations.
  • the choice of the cutting configuration will be determined based on the type and length of plant matter to be cut.
  • the first cutting configuration should be used to cut plant matter with a length in the range of 150 - 1000 mm.
  • the second cutting configuration should be used to cut plant matter with a length in the range of 20 - 300 mm.
  • the tractor is turned on and the drive system moves the mowing assembly.
  • the substantially horizontal axle rotates in the direction shown by arrow (18) in the Figures.
  • the mowing blades are forced outwards by centrifugal force created by rotation of the substantially horizontal axle (11).
  • the tractor moves forward and mowing is performed as should be understood by one skilled in the art.
  • barrier element (13) is moved to define the other configuration. Again mowing is performed as should be understood by one skilled in the art.
  • moving the mower (1) between the first and second configurations does not involve changing the height of the mowing blades with respect to the ground.
  • the barrier element (13) When cutting in the first configuration the barrier element (13) is substantially away from the channel (6). Cutting is performed and as the mowing attachment moves over long grass or plant material this abuts the flaps (7).
  • the flaps (7) can pivot to allow plant material to enter the cavity (9) without being substantially deformed or bent over.
  • the barrier element (13) When mowing in the second configuration the barrier element (13) substantially blocks the channel (6). This provides a rigid barrier across the channel (6). This allows the present invention to efficiently cut short length grass and/or plant matter. This is because the housing extends substantially down to the ground underneath the mower, thereby allowing greater and faster air movement to be created by rotation of the axle (11). That air movement lifts grass and plant matter to a position from which it can be cut.
