  • the invention also extends to a mower attachment for mounting on an ATV.
  • an ATV shall be understood to be a distinct species of vehicle that is a 4-wheel motorcycle having good ground clearance that is widely used as an all purpose vehicle particularly on farms and the like.
  • ATV's are well known to farmers and motorcycle dealers.
  • ATV's are built by many different manufacturers around the world including HONDA, YAMAHA, SUZUKI, KAWASAKI, SEADOO, POLARIS, ECON, ARTIC, CAT and RAZOR. The applicant estimates that they are used on over 70% of farms in Australia and New Zealand and that there are several million ATV's in regular use worldwide.
  • mower shall be interpreted broadly and include any contrivance for cutting vegetation such as grass and the like by means of a set of rotating blades.
  • a mower attachment shall be understood to mean an assembly including at least one blade for cutting grass and the like which is mounted, e.g. releasably, to a vehicle which moves translationally over a grass surface.
  • a push mower is a mower mounted on wheels with a rotatable blade mounted closely above the grass surface that is pushed along the ground surface by an operator walking behind the mower.
  • the mower has an engine that is used solely to drive the set of blades. Mowing large surface areas of grass such as is found in parks, large gardens and the like is very tiring and time consuming if a standard push mower is used.
  • This task can be made easier and more efficient by the use of a ride-on mower.
  • tractor/slasher arrangement Another machine often used on farms and acreage blocks is a tractor/slasher arrangement. This involves the use of a conventional tractor with a slasher attachment or accessory mounted thereto. However a tractor typically weighs from 1 to 6 tonnes and this large weight often causes deep ruts in the ground that is mowed. It also causes soil compaction which deleteriously affects the growth of vegetation and crops. Further the tractor has real limitations on the terrain it can negotiate in wet and slippery conditions.
  • a mower attachment for coupling to an ATV vehicle having front and rear wheels, comprising: a chassis for extending beneath the vehicle; a rotatable blade means vertically supported by the chassis and depending down beneath the chassis; a drive means for driving the blade means mounted on the chassis and driveably coupled to the blade means; and means for coupling the mower attachment to the ATV.

Applicant has found that this embodiment with the towbar is much easier to couple up to an ATV than the first embodiment and for this reason it is preferred.
  • An advantage of the contrivance described above is that it is relatively simple and inexpensive yet when coupled to an ATV vehicle provides a versatile mower. It is considerably more powerful than most ride-on mowers currently on the market.

  • the mower attachment is mid-mounted which provides additional stability. It also aids in giving the vehicle good manoeuvrability and an ability to handle difficult terrain. In addition by being mid-mounted it does not increase the vehicle length. Further the mower attachment and associated blades are positioned such that it is possible to mow up to the sides of garden beds, trees and the like. Further the control panel for the mower attachment is positioned within easy reach of an operator seated on the ATV.
