Definitions

  • Embodiments of the present invention relate generally to agricultural machinery.
  • embodiments of the present invention relate to a mower, particularly for use with plastic mulch.
  • the mower of the present invention is not limited to such applications and can be used where plastic mulch is not used.
  • Plastic mulch provides a range of benefits including helping modulate soil temperature, reduce soil erosion, evaporation, fertilizer leaching and weed problems and increase produce quality and yields.
  • the plastic mulch When the crops are harvested, the plastic mulch is often removed from the ground for disposal or recycling. Sometimes the plastic mulch is left in the ground and reused for the next crop. However, when the plastic mulch is left in the ground, plant matter, such as roots, stalks and branches etc. remaining from the previous crop still needs to be extracted from the ground whilst minimising damage to the plastic mulch.
  • Plastic mulch retrievers are agricultural machines designed for the removal of plastic mulch and are typically drawn behind a powered vehicle, such as a tractor.
  • Some known plastic mulch retrievers comprise a pair of cutting elements in the form of coulter wheels at a front end, which cut into the ground and the plant matter.
  • a pair of angled, substantially horizontal blades mounted rearward of the coulter wheels also cut into the ground and underneath the plastic mulch embedded in the ground.
  • a centre coulter wheel usually located rearward of the pair of coulter wheels slices the plastic mulch into two halves. The positions of the coulter wheels are adjustable to accommodate different sizes of planting beds.
  • Another known modified mulch retriever comprises a plurality of propane burners rearward of the coulter wheels and angled blades.
  • the burners incinerate the unearthed mulch and exposed plant matter thus avoiding the need to collect the mulch and plant matter.
  • incineration is environmentally unfriendly and illegal in some jurisdictions.
  • the burners also require a propane tank, which adds to both the financial and environmental cost. This machine is also unsuitable where the plastic mulch is to be left in the ground and reused.
  • embodiments of the present invention reside in a mower comprising: a body supporting a motor; and one or more blades coupled to and driven by the motor to cut plant material and extract the plant material through the body; wherein the body is mountable to a powered vehicle.
  • the mower is particularly useful with plastic mulch for removing plant material and other debris from the plastic mulch, but the mower can be used in other applications.
  • the body comprises a cylinder and the plant material is extracted upwards through the cylinder.
  • the body comprises a support arm extending from a wall of the cylinder.
  • the motor is mounted to the support arm, preferably an end of the support arm, such that the motor is located on a central axis of the cylinder.
  • a surface of the blades is curved upwards.
  • the motor is selected from one of the following: a hydraulic motor coupled to a hydraulic system of the powered vehicle; an electric motor coupled to an electrical system of the powered vehicle.
  • a hood is mounted to a top surface of the cylinder to direct the plant material and any debris rearward.
  • one or more support wheels are rotatably mounted to the body.
  • the body comprises a front mount.
  • a floating linkage is rotatably coupled at a first end to the front mount.
  • the floating linkage comprises a pair of parallel, spaced apart elongate members rotatably coupled to each side of the front mount.
  • an upper pair of the elongate members is joined together with at least one transverse member and a lower pair of the elongate members is joined together with at least one transverse member.
  • the front mount comprises at least one stop to limit travel of the floating linkage.
  • the floating linkage is rotatably coupled at a second end to a frame assembly.
  • the floating linkage is rotatably coupled to a mount of the frame assembly.
  • the frame assembly comprises one or more transverse tubes.
  • one or more cutting elements are rotatably coupled to one or more of the one or more transverse tubes.
  • the frame assembly comprises a hitch for coupling the frame assembly of the mower to the powered vehicle.
  • the body comprises a rear mount.
  • one or more wheels or rollers is/are coupled to the rear mount.
  • one or more arms are pivotally coupled to the rear mount to which the one or more wheels or rollers are rotatably mounted.
  • an arm is pivotally coupled to each side of the rear mount and the arms are coupled by a transverse brace.
  • the transverse brace comprising a pivot post.
  • the body further comprises a mounting post.
  • an actuator such as a hydraulic cylinder is coupled between the pivot post and the mounting post to adjust a position of the one or more wheels or rollers relative to the body of the mower.
  • an actuator such as a hydraulic cylinder is coupled between the pivot post and the mounting post to adjust a position of the one or more wheels or rollers relative to the body of the mower.

  • the mower 10 therefore substantially clears the surface of the plastic mulch of plant matter and debris ready for the mulch to be re-used or ready for more efficient retrieval of the mulch. If the cut plant matter and debris is not collected, for example by a following vehicle, the cut plant matter and debris easily falls off the plastic mulch when it is retrieved. The clean plastic mulch is easier to recycle or takes up less landfill volume. Also, more plastic mulch can be collected in the aforementioned storage devices of the mulch retrievers. For example, after the mower 10 has been used, one type of mulch retriever can retrieve mulch from five rows before the storage device needs to be emptied. In contrast, without using the mower 10 of the present invention, the same mulch retriever must be emptied after each row due to the plant material and other debris adhered to the plastic mulch.
