The power harrow element – HR 4040 – uses straight blades and a Duplex gearbox, enabling rotor speed to be adjusted according to soil conditions.

The VENTA seed drill features a 1,800 litre seed hopper and uses a fluted metering unit with large splines for larger seeds( wheat, barley, peas, beans, etc.) and small splines for smaller seeds such as rape and alfalfa. Seeding rates can be set from the tractor cab at between 1 and 430 kg / ha. A remote calibration“ start button”, located close to the VENTA’ s metering unit, makes calibrating the machine easy to achieve without the need to go back into the tractor cab to access the drill’ s main control panel.

A speed sensing radar ensures

precise seeding at up to 15 kph and it is possible to shut-off every second row for special applications. KUHN’ s precision coulter bar, the SEEDFLEX system, takes care of seed placement, with widely offset double discs mounted on a parallelogram to enable fast and accurate seeding. These maintenance-free coulters perform well in all soil conditions, from ploughed to min-tilled land. Following press wheels control seeding depth and ensure good soil to seed contact for consistent germination.

Tillage and seeding are carried out independently thanks to a roller frame design which effectively separates the two functions. This patented design allows for a more compact unit and enables the two units to be uncoupled in less than 10 minutes.

The VENTA 4030 + HR 4040 is suitable for use with tractors with a power output of up to 234 kW or

320 hp. Single rotor, mounted grass rake

KUHN will also be displaying its new single rotor, mounted grass rake, the GA 4431, at LAMMA.

The GA 4431 is one of three new grass rakes from KUHN: the GA 4431, GA 4731 and GA 5031 work across 4.40 m, 4.65 m and 5.00 m widths respectively and have been designed to be simple to operate and compatible with lower powered tractors.

KUHN’ s MASTERDRIVE GIII system features on each of the new machines. This patented, two stage gearbox uses a bevel and spur gear reduction system which has proven to be exceptionally reliable on the company’ s larger twin and four-rotor grass rakes. The gearbox is totally enclosed, requires minimal maintenance, and with no crown wheel and pinion, has a reduced wear potential which means fewer breakdowns, even during intensive use.

The new single rotor GA machines have been designed to reduce the time spent changing from road to field mode: an ergonomic support arm and central locking design make the changeover quick and simple. Windrow deflectors and guards are operated manually or can be operated hydraulically as an option.

The headstock provides the raking rotor with a windrow clearance height of more than 40 cm and excellent contour following capabilities. This ensures excellent forage quality conservation and makes the machine easier to manoeuvre when working in tight spaces or on uneven / sloping ground. Raking height is easily adjustable via the use of a handoperated crank handle and enables the rake to be fine-tuned to suit the terrain and to minimise soil contamination.
