The latest addition to Kuhn’s Combiliner range, the pneumatic Venta NC, is a high-speed combination designed with the versatility to drill into ploughed or un-ploughed land.
Available in 3 and 4 metre working widths and combining the established Venta pneumatic drill technology with the latest HR1003 series power harrow, this new model is a significant departure from earlier combinations.
The Venta NC draws on direct drilling technology developed in the successful SD range, with a coulter bar comprising steeply offset double-discs on a parallelogram linkage providing the penetration for high speed drilling into hard soil surfaces. A 35cm clearance between the two rows of discs assists operations in cloddy or trashy soil conditions. The relative position of the guide wheels and the independent movement of each seeding unit ensure constant and accurate seeding depth. Both seeding depth and the ground pressure of the seeding units are centrally adjustable.
A substantial 2000 litre hopper with easy loading access complements the Venta NC’s high-speed drilling capability, reducing down-time for loading and potentially avoiding the need to transport seed to the field on a separate trailer.
The combination is designed with the seed drill independent from the power harrow. This assists drilling accuracy by avoiding vibrations being transmitted from the cultivation tool to the coulter bar, with the coulter bar remaining in a constant position even if the roller setting is changed. The coulter bar can be lifted out of work hydraulically, allowing the power harrow to operate independently.
The Venta NC combination has a compact design, to improve stability both in work and in transport. This is achieved by positioning both the hopper and the power harrow roller in relatively forward positions, whilst seeding elements are constructed of treated steel to reduce weight.
The Venta NC has offset seeding units arranged in two rows.
