Features

Heavy-Duty 100 Series Cutterbar

The 100 Series Cutterbar withstands the highest loads. The special high-capacity bearings fitted in a one-piece sealed housing are not subject to distortion. The disc pinion shaft bearings endure radial forces for maximum bearing life. This optimum position improves the load balance for increased service life. The knife attachment hardware is fully protected for high wear resistance. The idler gear fasteners are located in heat treated steel cups and correct alignment is ensured without the risk of distortion. The GMD mowers can be equipped with Fast-Fit knives in an optional kit. They allow the operator to rapidly change knives in the field. Fast-Fit is only possible on standard discs, which is included in the kit.

Protectadrive® Safety

The Protectadrive system protects the gear train in case an obstacle is struck: the threaded pins of the disc housings are solidly linked to the upper half casing. There is no weak point or risk that they could be ripped out. The disc bearing station can be removed and mounted quickly and easily. A possible repair is carried out at reduced costs from the outside with minimum downtime.

Single-Lever Control

Through the design of the mowing unit articulation, mowing banks and terraces is possible at a tilt angle up to 35° and down to -25°, depending on the model. The lift and suspension system allows both the cutterbar and the inner shoe to be raised off the ground using only the mower’s hydraulic cylinder, simplifying operation and increasing productivity. The tractor’s 3-point hitch stays at the same preset height.

Cat 2 Quick Hitch Compatible

The GMD Premium Series models are compatible with tractor attachments, equipped with a Quick-Hitch frame, category 2, making hookup to the mower fast and easy. Quick-Hitch must meet current ASABE specifications.

Standard Outer Swath Wheel

A swath wheel is mounted behind the outer disc cone and separates cut from uncut crop allowing the right tractor wheels to drive over the ground instead of the previously cut crop. Swath wheel advantages over a swath board include: it fits entirely under the curtain, has no ground contact and damage by backing or turning is eliminated.
