It´s the quality of forage stored in silos or bales that makes an important difference for farmers who want to increase the profitability of their livestock. The aim is simple: produce as much meat or milk as possible from the basic feed ration. Paying attention to the forage during harvesting is essential! The four belt-driven swath drums of the GMD 100 F series front-mounted mowers form fluffy, well-aired and narrow swaths, which will not be run over by the tractor wheels. This facilitates swath pick up by balers and self-loading forage wagons, with no risk of soiling the forage. In situations with heavy or long forage, serrated metal bars can be fitted on the drums to increase flow to the rear.
The “trailed” mower unit is attached to the frame by rods. With the special suspension concept, it is able to pivot +/- 6° left to right as well as minus 6° down and plus 5° up but can also travel 50 cm vertically – perfect prerequisites for excellent ground adaptation that result in clean forage, both during daily operations on soils that are often still wet or for hay and silage making. When faced with an obstacle The mowing unit lifts like a ski tip, goes over the obstacle and returns to its normal position automatically.
The cutter bar has been designed to handle obstacles. With the PROTECTADRIVE safety system, in the event of a violent impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing thanks to a carefully dimensioned shear groove. The toothed wheels are protected. In less than 15 minutes, the machine is operational again and at a very low repair cost. Top-of-the-range components reinforce the most precious parts of the cutter bar: – Special disc-bearing station with a double row of angular contact ball bearings.- Large-diameter gear wheels in high-precision forged steel with 3 cogs engaged. – Discs with forged and treated cups across the surface area.- Disc skids in treated steel with the option of adding a protective layer (screw on)
The protective sheet metal plates located between the discs protect the cutter bar by automatically guiding upward distorted knives. Thus, the cutter bar is not damaged and preserved from the soil’s abrasiveness and residues present in the forage. Skids reinforced for wear resistance by heat treatment also protect the cutter bar.
The high-strength steel knives are manufactured according to very precise standards. For more safety and longevity, their fastening is ensured by a special system. The mowers GMD 100 F series can also be fitted with the FAST-FIT quick kniferelease system which provides 3 additional guarantees:
The cutting quality remains excellent thanks to the compactness of the cutter bar and the exclusive shape of the knives which pass as close as possible to the protective skids.
Combined with two rear units, the GMD 280 F and 310 F allow reaching up to 8.80 m of cutting width. The reduced weight of the front-mounted disc mowers ensures a high work output also with medium-power tractors.
To ensure a very long service life of your mower:
To prevent tool damage while mowing along field edges or next to a tree, the flexible side guard, FLEXPROTECT, can bend in and out of shape. It avoids additional repair costs. It is easy to deploy, no tools required
