The range of KUHN pneumatic seed drill combinations now includes the VENTA 320 with a working width of 3.00 meters and a hopper capacity of 850 litres. Thanks to its light and compact design, it is suitable for tractors of 120 hp and more. It has been designed to make all essential machine adjustments quick and easy. The QUANTRON S2 terminal makes it possible to monitor the distribution and modulate the seed application rate from the tractor cabin. Easily combinable with the KUHN HRB 302, HRB 303, HR 304 and HR 3004 power harrows and fitted with single-disc seeding units, the VENTA 320 pneumatic seed drill ensures precise sowing in all conditions.

Hydraulic blower drive
The Venta 320 is equipped with a hydraulic blower drive that is independent of the tractor PTO speed. Thus, the blower's speed is not affected by fluctuations in the engine speed. This has many advantages:
Reduced oil consumption
Thanks to an optimized pneumatic circuit, it is now possible to reduce the blower speed. Enjoy reduced oil consumption with only 15 l/min for small seeds and 26.5 l/min for large seeds. A sensor on the blower drive monitors the speed and triggers an alarm in the event of excessive speed.
The VENTA 320 seed drill has been designed so that all essential machine adjustments are quick and easy to perform.
The seeding depth is adjusted on both sides of the seed drill using a crank and a spanner. A marker explicitly indicates the direction of rotation. The open-end wrench can be stored on the seed drill to always be close at hand.
The coulter pressure of each seeding unit is adjustable up to 32 kg. It is adjusted once using a crank located next to the coulter bar. Hydraulic adjustment of the coulter pressure is available as optional equipment.
The VENTA 320 seed drill hopper can easily be filled with a big bag thanks to its large opening. Its access is facilitated by a wide loading platform and a retractable ladder.
The distribution head is located at the rear of the hopper. A step facilitates access for cleaning tubes or when changing seeds.
To make the calibration test as simple as possible, all essential tools are at your fingertips. The operator's manual is stored at the level of the ladder and the calibration bag under the hopper. A retractable and extendable holder allows you to hang the scale (supplied as optional equipment) and the bag. The metering unit is also easily accessible. An on/off button to start or stop the calibration test is placed on the hopper near the metering unit.
The QUANTRON S2 terminal has proven itself on KUHN seed drills for many years. It is suitable for non-ISOBUS tractors and is characterized by its colour screen as well as its intuitively arranged navigation keys. It incorporates many features:
- modulation of the seed application rate from the tractor cab;
- monitoring of the application rate, the blower speed, the low level in the hopper;
The VENTA metering system is recognized for its simple design and its precise and regular work. The centralized metering unit with volumetric fluted roller makes it possible to distribute all types of seed, from the smallest to the largest, with a rate precision ranging from 1 to 430 kg/ha. There is no need to disassemble or change parts on the metering unit, even for small seeds. To protect delicate seeds, it is also possible to disengage the agitator without tools. The metering unit is electrically driven, which allows you to modulate the seed application rate directly from your tractor cabin.
The VENTA 320 seed drill is available with row spacings of 15.00 or 12.50 cm. The seeding units are distributed over two rows 27 cm apart. This design helps avoid clogging even in wet conditions or in the presence of plant debris. Consisting of a large-diameter disc (Ø 327 mm), the single-disc seeding unit ensures optimum furrow opening quality. The slight angle of the disc makes it possible to minimize the projection of soil in the row, which is particularly appreciable when seeding at high speed. A cast iron coulter placed on the side of the disc consolidates the furrow and precisely delivers the seed in the ground.
The coulter pressure of each seeding unit is adjustable up to 32 kg in order to maintain sufficient seeding depth in heavy soils or when deep seeding at a sustained speed. The adjustment of the lower stop allows precise control of the seeding depth, including in heterogeneous fields or when performing shallow seeding with significant pressure. These settings are independent of each other.
The coulter bar is guided by the power harrow roller. In this way, the seeding depth is always constant, independent of the working depth of the power harrow. Adjusting one does not affect the position of the other.
