Piranha Twin Rotor Slasher

Piranha Twin Rotor Slasher

Twin rotor slashers consist of two right angle gearboxes and one transfer gearbox or T-Box which is between the two rotor gearboxes to do three major functions.

 

One is to drive the two rotor gearboxes. Two is to keep the main drive shaft in as straight as possible. The third is to use the safety friction clutch on the input shaft for drive line protection and essentially keep the two rotors timed or synchronised.

 

The Twin Rotor’s main advantage over a Single Rotor unit is the increase in width with out getting to deep for eg; a 2500mm wide unit is only 1250mm deep. Or half its width which markedly cuts down on the leverage weight of the unit and keeps the weight closer to the rear wheels of the tractor which can be essential in some steep terrains.

 

With two rotors you can set the unit up to deliver the cut material in a few different configurations. The most common being material is ejected or delivered out to either side of the unit using a side delivery model to throw mulch under vine to assist with weed suppression, reduce chemical application and help with water retention.

  • Twin Rotor

    Twin Rotor Heavy Duty Slashers are designed for 35-80hp PTO tractor range and come in 8 different sizes which have the following features.

    • Dual Category Pick up pins Cat 1 & 2 with slotted top link.

    • Available in either Centre Mount, Offset or Double Headstock

      (Some models only).

    • Available with either fixed sides or Twin Side Delivery.

    • Drive Shaft is a telescopic triangular profile 6 series shaft.

    • 75-80hp Gearbox has precision cut case hardened gears with

      high quality tapered roller bearings used throughout.

    • Laminated spring steel blade beam with hardened dip down

      twisted mulching blades on a hardened swing back bush.

    • Exclusive 2 Year Warranty on all Piranha Slashers.

    Another configuration is a single side delivery unit. This has two rotors spinning clockwise to throw all the material out to the right hand side, this is generally used in an orchard situation when two pass mowing is required. A further option is both rotors spinning into the centre to leave the material mid row or directly behind the unit.

  • Twin Rotor (Drop Centre)

    Drop centres are designed for V shaped or delved ground, they have two rotor gearboxes that are on individually floating wings that follow the contours of the V ground. They have one main power divider that drives the two rotor gear boxes at 40 degree angles via two short star shaft pto shafts. The hinges use a full length 22mm stainless steel hinge pins and allow the unit to mow up to a 15 degree V on each wing or 30 degree combined. Drop centres come standard with two rear rollers and three front rollers to keep snug to the ground contour.

     

    Twin Rotor Drop Centre Slashers are designed for 35-100hp tractor range and come in 8 different sizes which have the following features.

    • Dual Category Pick up pins Cat 1 & 2 with slotted top link.

    • Available in only Centre Mount.

    • Available with either Fixed Sides or Twin Side delivery.

    • 120hp Transfer Gearbox with two 75hp Rotor Gearboxes.

    • Drive Shaft is a telescopic triangular profile 6 series shaft with

      High quality star shafts between gear drives.

    • 75-120hp Gearbox has precision cut case hardened gears with

      high quality tapered roller bearings used throughout.

    • Laminated spring steel blade beam with hardened dip down

      twisted mulching blades on a hardened swing back bush.

    • Come standard with 2 rear & 3 front rollers to follow ground

      contours.

    • Exclusive 2 Year Warranty on all Piranha Slashers.

  • Twin Rotor Pasture Topper

    Pasture toppers are essentially a Twin Rotor unit with the main difference being a higher tip or peripheral speed to cover the ground
    at quicker speeds – required for pasture rejuvenation or stubble cutting. They generally cut slightly higher than a standard slasher and are designed for taking the top of established pastures or paddocks at a slightly higherspeed. Pasture toppers can be supplied as a skid run model or with rear castor wheels.

     

    Twin Rotor Heavy Duty Pasture Toppers are designed for 50-150hp
    PTO tractor range and come in 2 different sizes which have the following features.

    • High Tip Speed to allow for higher ground speed.

    • More under body clearance for even distribution of cuttings.

    • Dual Category Pick up pins Cat 1 & 2 with slotted top link.

    • Available in either Centre Mount or Trailed.

    • Comes Standard with Adjustable sides and is Skid Run.

    • Choice of 80hp T-box with two 75hp Rotor Gearboxes or

      150hp T-Box with 130hp Rotor Gearboxes.

    • 75-80hp & 150hp-130hp Gearboxes have precision cut case hardened gears with high quality tapered

      roller bearings used throughout.

    • Laminated spring steel blade beam with hardened

      dip down twisted mulching blades on a hardened swing back bush.

    • Exclusive 2 year warranty on all Piranha slashers.
  • Twin Rotor Hydraulic Drive

    With the larger capacities of today’s hydraulic machinery Ben Wye Engineering has designed a range of hydraulic slashers to suit Skid Steers, Loaders, Tractors & Harvesters. As there are several makes and models on the market of all these machines, hydraulic units are generally customised to suit that particular machine.

    • Min 80ltr/min.

    • Heavy duty pick ups fabricated to suit most machines.

    • 4-6mm decks depending on the environment.

    • Direct 1:1 drives through to 1:1.93 increase drives.

    • Laminated spring steel blade beams or Bis plate disk rotors.

    • High quality torque or gear motors.

    • Overrun check valves hard piped standard.

    • Cross line Relief valves (depending on application).

    Excavator slashers are an extremely useful tool in inaccessible areas and give the operator a huge reach to clean up creek beds steep ground and around obstacles.

     

    With Ben Wye Engineering and Design exclusive direct drive hydraulic drive slashers you can eliminate the need for coupling of the hydraulic
    motor to shafts, thus saving room, components and the need for guarding of the rotating parts. Maintenance becomes easier and alignment is precise. These twin rotor units are Ideal on skid steer or loader attachment as they give a greater width to depth ratio.

     

    The mechanisation of vineyards and the use of under-harvester slashers has bought a new era in vineyard maintenance. With the under-harvester slasher you can half your operator time by cutting two rows at once, make full use of your investment by turning your harvester into a year round implement.

     

  • Twin Rotor Single Flex Wing

    3600 Single Wing Flex Wing mower is designed for road side contractors, large area mowing and large planted orchards.

     

    This unit is a three point linkage hybrid of the Piranha Flex wing. Ideal for roadside mowing with the unit folding for road transport whilst still giving the benefits of the Flexwing style slasher. The three point linkage mount delivers precise control around obstacles, coupled with the versatility of the floating wing.
