Forage Harvesting




For over 50 years, DEUTZ-FAHR drum mowers have set the benchmark for others to follow. Even in the most challenging conditions, these machines offer the farmer the peace of mind of perfectly clean, precise mowing results. DEUTZ-FAHR drum mowers draw from the experience gained from manufacturing over 700,000 machines - a figure that no other constructor manufacturer even comes close to matching!

For maximum productivity, DEUTZ-FAHR has developed the DM 428F, DM 432F and DM 631F front-mounted mowers, with cutting widths from 2.70 to 3.10 m, and the innovative DM 493 triple mower, which can mow with three different cutting widths (8.40, 8.65 and 8.95 m). With the DEUTZ-FAHR DM 493 triple mower, a 74 to 110 kW tractor (100-150 hp) is all you need to achieve unparalleled productivity. At just 1900 Kg, the DM 493 offers an outstanding power to weight ratio and is light enough to limit soil compaction, while the compact dimensions of the machine itself ensure superlative manoeuvrability.


With a choice of five models - KM 3.16, KM 3.18, KM 3.21, KM 4.27 and KM 4.29 - DEUTZ-FAHR offers a range of superlative quality mowers with working widths from 1.65 to 2.95 m. Ideal for the small to medium sized farm. The KM 3.16, KM 3.18 and KM 3.21 feature 2 drums with outlet deflectors, while the KM 4.27 and KM 4.29 raise the bar for drum mower productivity. The incredibly effective combination of two large outer drums and two small inner drums generates an extraordinary flow of cut grass for superlative productivity. And despite being capable of mowing enormous quantities of forage, the KM 4.27 and KM 4.29 have low power demands.

Complementing drum mower range alongside the KM series are the DRUMMASTER 427, 431 and 631, with innovative, intelligent solutions for superlative productivity and with working widths of 2.70 and 3.10 m. The modular construction of these mowers makes unscheduled maintenance significantly easier, as the drums may be removed individually. Another advantage of the modular construction is the absence of drive belts - the entire transmission consists of a gear train immersed in oil, for unparalleled safety, reliability and durability. What sets these mowers apart is the LIFT-CONTROL system. This is much more than a mere suspension system, and uses nitrogen accumulators instead of conventional mechanical springs to maintain a constant ground pressure and ensure clean mowing results. The DRUMMASTER 631 is equipped with the FREE-FLOAT suspension system, which allows the mower to precisely follow the contours of the terrain. This advanced system not only offers vertical and transverse freedom of movement, but also allows fore/aft movement to prevent damage to the turf and keeps the cut grass free from soil.

Impeccable terrain following performance
Boasting a simple, rigid frame, DM428F and 432F models represent the most cost-effective choice for the commonest applications. The fixed link or PENDELFLEX link ensure that the mower follows the terrain perfectly longitudinally. Transverse unevenness is compensated for by the arms of the front lift.
The DM 631 is equipped with the FREE FLOAT suspension system, which not only allows lateral freedom and vertical of movement, but also allows the mower to move forwards and backwards. This prevents damage to the turf layer and keeps the cut grass free from soil.

The right ground pressure in all conditions
Large compensator springs (on DM428F and DM432F models) or a hydraulic system (DM631F) limit the pressure applied to the ground, transferring the weight onto the front axle of the tractor. This minimises turf damage and improves the manoeuvrability of the tractor.
