VX65 Parallelogram Tyne Units

Boss Agriculture VX65 Parallelogram Tyne unit

Boss Agriculture's VX Series of parallelogram tyne planting units set the standard in broadacre seeding; from the front to the back the Boss VX Series is built on experience to deliver a planting unit that is accurate, tough and simple to operate & maintain.

The VX65 offers a 125lb - 625lb variable hydraulic breakout on the tyne trip & variable hydraulic downforce integrated into the tyne breakout ram in a compact parallelogram row unit. With 10" of parallelogram travel and a 1" x 2" planting tyne to open the widest planting window whilst still maintaining accuracy and low disturbance.

VX65 Features & Benefits:

  • True parallelogram row unit delivers better accuracy due to the fact that the relationship between the tyne and press wheel stays constant regardless of the units operating height.
  • Constant downforce on the press wheel regardless of the tynes working range.
  • Tyne breakout pressure & press wheel pressure are independent of each other and not proportional like some of our competitors.
  • Tyne entry stays constant regardless of planting depth
  • The parallelogram clamps diagonally to an RHS toolbar to ensure the unit locks in and is not able to twist on the frame.
  • All pressure and depth adjustments are either pin or hydraulically adjustable – No tools required
  • Individual units can be lifted up hydraulically when operating on wide or skip row spacing’s.
  • Parallelogram pivots are fitted with replaceable bushes and 1¼”chrome plated pins for reliable & smooth operation.
  • Optional pivoting coulter disc to cut through the trash & fracture the soil.
  • Range of press wheel profiles available including 1”, 11/2”, 2”, 3” Vee Wedge & 4” pneumatic with a single rib.
  • Range of points available including spear points, winged points, fabricated knife points or Keech points.
  • The press wheel assembly operates on a greasable Holden hub fitted with marine seals and steel seal protector.
  • Fitted with a 1” x 2” heat treated spring steel planting tyne with pin adjustable depth control in ¼” increments.
  • Removable seed boot which means it can be easily replaced with different attachments, or simply pulled off to be hard faced back in the workshop without removing the tyne.
  • Heavily constructed tyne box fitted with replaceable bushes and 1¼” chrome plated pins.
  • Optional Boss double disc shank can be used by simply replacing the tyne. The double disc offers very low disturbance and will run in heavy trash conditions whilst delivering excellent moisture & fuel savings.
  • Available options include diffusers, chain harrows, press wheel scrapers, liquid fertiliser tubes, gas tubes, press wheel lockouts & double shoot tynes.
