Low-weight, front mounted mowers available for medium-sized tractors

Kuhn Farm Machinery has added two new compact, low-weight, front mounted mowers to its range of hay and silage making equipment: the GMD 2820 F COMPACT and GMD 3120 F COMPACT are suitable for use with medium-sized (37-43hp) tractors and have been designed to be as light as possible whilst still providing Kuhn’s unrivalled levels of performance and reliability.

The GMD COMPACT mowers are designed for use on uneven terrain and upland pastures and are available with either a bolted yoke mounting system or quick-hitch A-frame.  A central pendulum-type single pivot enables the mowers to accurately follow ground contours: ground pressure adjustment can be made directly from the tractor for those equipped with an integrated front lift system.  Alternatively, powerful mounting springs, located between the attachment frame and tractor, can be used to control the mowers’ vertical movement.

Both machines use Kuhn’s proven OPTIDISC cutter bar which is fitted with six (GMD 2820 F) or seven (GMD 3120 F) cutting discs, each of which are equipped with two knives: each disc rotates towards the centre of the machine ensuring the crop is rapidly and neatly ejected to the rear of the machine.  The GMD 2820 F cuts to a width of 2.70m (8’10”) and produces 1.30m (4’3”) swaths, while the GMD 3120 F cuts to a width of 3.14m (10’4”) and produces 1.50m (4’11”) swaths.

A sealed, lubricated-for-life gearbox makes the new GMD COMPACT machines easy and simple to maintain, while individual PROTECTADRIVE shear points on each disc’s driveshaft protect the cutter bar’s internal components from impact damage: in the event of a violent impact between a disc and an obstacle, the shaft holding the disc will shear just above the bearing.  The shaft can subsequently be replaced in less than 15 minutes, reducing downtime and eliminating expensive repair bills.

Optional equipment for both models includes swath width reduction plates, suspension springs, an attachment offset kit and running and signalling lights.
