CLEAN AND EVEN CUTTING
Proven 100 Series Cutterbar
Due to the high reliability, excellent crop cutting, and overall adaptability to varying terrains, the 100 Series cutterbar is a staple in the Premium Series. See for yourself by taking a closer look at what the 100 Series cutterbar has to offer
1.Withstands the highest loads: special high-capacity bearings fitted in a one-piece sealed housing are not subject to distortion.
2.Increased service life: disc pinion shaft bearings endure radial forces for maximum bearing life. This optimum position improves the load balance.
3.Protection should an obstacle be struck: the Protectadrive® system is designed to protect the cutterbar gear train and minimizes the risk of downtime.
4.High-wear resistance: knife attachment hardware is fully protected. For added safety, heat-treated steel cups are welded to the disc.
5.Minimum wear or distortion risks: idler gear fasteners are located in heat treated steel cups. Correct alignment is ensured without the risk of distortion.
6.Long-term reliability: large-diameter gearwheels in high-tensile forged steel with reinforced teeth.
7.Perfect sealing: top-quality o-rings used on cutterbar bearing housings for a perfect, leak-free seal.
Standard Discs for Clean Cutting
Standard discs allow for clean cutting and quick crop evacuation. Beveled reversible knives are standard. Ribbed knives are available for rocky conditions.
The shape of the discs allows for a quick transfer of crop rearward, allowing the crop to quickly be formed into a swath. A recut of the grass is therefore avoided. As crop leaves the cutting area, no outside support greatly reduces the chance of crop wrapping.
The swath wheel is mounted behind the outer cone and functions to separate cut crop from uncut crop allowing the right tractor wheels to drive over the ground instead of previously cut crop. Advantages of the swath wheel include it fitting entirely under the curtain, not being in contact with the ground and eliminating damage when backing or turning sharply.
PEACE OF MIND
Every minute saved during the hay season is precious. Ultimate protection, from the externally removable Protectadrive disc bearing stations, provides maximum reliability and quick service. In the event of an impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing. This is thanks to its carefully dimensioned shear groove. As a result, the gear teeth are protected.
Safety Breakaway Mechanism
Should an obstacle be struck, the safety breakaway causes the mower unit to swing slightly backwards. The impact is significantly reduced. You can reset the device simply by reversing.
ADAPTABLE TO VARYING TERRAIN
Articulated Cutting Unit
The articulated cutting unit follows ground contours with maximum accuracy even when mowing banks or ditches.
Suspension Spring for Accurate Ground Adaptation
The suspension spring allows accurate adaptation of cutterbar flotation to ground contours. The flotation spring tension is determined by adjusting the main frame height using the tractor’s 3-point lift.
The new hitch design of the Select Series incorporates a more vertical angle of the round attachment frame which greatly improves overall strength. Due to this, the machine mounts closer to the tractor reducing the overhang, power, and ballast required.
The design of the GMD 16 and GMD 20 is slightly different than that of the GMD 24 and GMD 28 mowers. GMD 24 and GMD 28 mowers have a longer top link attachment point due to the increased working widths. It is important to note that all Select Series machines require the operator to lift the hitch and activate the cutterbar lift hydraulic circuit for headland maneuvers. The frame allows up to a 2” offset to the right for tire clearance. The hitch is not designed to be Quick-Hitch compatible.
