The Optima TFmaxi from Kverneland Accord offers the ideal precision seed drill technology. The large trailed version of the proven Optima precision seed drills, the Optima TFmaxi is ideally suited for today’s modern large scale farmers and contractors.

With a working width of 12m and a 4000 litre capacity fertilizer hopper, the Optima TFmaxi offers a unique performance. Up to 100 hectares in one day – thus reducing the costs for the tractor and the driver.

The Optima TFmaxi combines high performance technology with maximum user friendliness. The machine’s clear and logical layout together with the high level of intelligent technology offer the user maximum ease of use, from set-up and filling, to transport and seeding operation

The Advantages:

• Sowing of maize with 12m working widths and 16 rows
• Proven technology for the application of seeds in combination with innovative frame technology
• Fully integrated fertilizer spreader
• Fully ISOBUS-compliant.
• 50 km/h transport on the road
• Easy handling

Optima TFmaxi – Frame

• The Optima TFmaxi is based on a stable, telescopic frame of 250 x 450mm main chassis. The complete control umbilical for electronics and hydraulics is safely positioned inside the frame.
• Due to the hydraulic drive via pto shaft being mounted at the cross shaft, excellent manoeuvrability has been achieved.
• A turning angel of 80° allows seamless coverage of the field with tight headland turns. The standard cross shaft is Cat. 3N, alternatively Cat. 4N is an option, both guaranteeing high stability.
• When converting the machine into transport position the frame is extended so that the two wing sections are folded parallel to the main frame. When in the transport position the overall width is 3.0 metre

Optima TFmaxi – Hopper

• 4.000 litre capacity
  Opening: 2.31 x 2.45m; Height: 3.49m
• Loading step for a safe access to the hopper
• Slide for easy and quick emptying of remaining seeds
• Hopper low level sensor adjustable in height
• Water and dust-proof hopper cover made of steel with an easy folding mechanism
• Optional filling auger with a filling height of 750mm
• Automatic unfolding of the filling auger when the machine is in working position

HD sowing unit

For mulch and conventional sowing

• The heavy basic weight of the sowing unit together with the possibility to add additional pressure (up to 100kg) onto each individual sowing unit via the optional spring loaded system allows optimum depth control even unter extreme conditions.
• Effective ground contour following, due to the large lateral depth control wheels (Ø 400mm, width 120mm), precise seed placement and seed covering by means of the intermediate press wheel and the multi adjustable V-press wheel, ensure maximum field emergence.
• The sowing unit Optima HD can be mounted on all Optima frames (3-point linkage or trailed).

Seeding Heart Optima

Seeding heart without seals

• The patented seeding heart by Kverneland Accord has reduced maintenance costs to a minimum
• No friction, no wear, low drive torque, minimum maintenance: The seed disc rotates in the seeding heart together with the vacuum chamber. This seeding drum is connected to the vacuum fan via a hollow shaft
• This seed heart principal results in no loss of vacuum, and therefore a low vacuum requirement

Optima e-drive / e-drive II

e-drive/e-drive II – complete control and monitoring of the machine from the tractor cab in accordance with ISOBUS standard

• With e-drive/e-drive II, each sowing unit is driven individually via an electric motor.
• The low-maintenance drive is connected directly to the seeding heart via a toothed belt in an encapsulated dust proof housing.
• This enable an extremely compact design and smooth drive characteristics with low current consumption
• All the data is entered and read out via an ISOBUS terminal like IsoMatch Tellus or Tellus GO.
• The sowing distances are infinitely adjustable and can be changed during sowing.
• All the sowing units can be switched off individually.
• In conjunction with “close row” sowing widths of 37.5cm a further benefit of the e-drive/e-drive II comes into play: Individual tramline switching. Tramlines can be set up for any spray width.
• The e-drive/e-drive II features complete electronic monitoring of all machine functions including seed monitoring via an opto sensor.

ISOBUS Intelligence – GEOcontrol

IsoMatch GEOcontrol – Cost saving with immediate payback

Seeding with GPS and GEOcontrol in combination with an electric driven precision drill is a major step towards precision and cost saving. These machines are all equipped with ISOBUS technology which with the help of the IsoMatch Tellus terminal, can be easily controlled.

Each electric driven seeding element, in combination with GPS and GEOcontrol, is automatically switched on or off in exactly the right place, ensuring there is no overlap with any row that has already been seeded. This is especially handy in triangular fields, on curved or irregular shaped headlands.
