Optidisc® Cutterbar with Fast-Fit

This innovative cutterbar design offers exclusive differential disc spacing. Narrower spacing at diverging discs provides greater knife overlap for cleaner cutting. Wider spacing at converging discs provides greater capacity and higher throughput. Fast-Fit® allows quick changing of knives with the use of a simple tool, yet still provides the optimum cut quality and knife life seen with the standard system. With Fast-Fit, you can achieve up to 50% time savings.

Central Drive

The gearbox drives the central discs of the cutterbar reducing stress on the cutting unit. The two drums separate the crop flow to form two swaths if desired. A wide (13’1”) continuous swath can be formed for maximum drying.

Increase In-Field Efficiency

With a center pivot, the operator can increase in-field efficiency by mowing fully to the left, right or anywhere in between for maximum productivity.

Rapid and Easy to Use Narrow Transport System

Rapidly transition from transport to field and back again. The GMD 5251 TC is practical and fast on roads along with being easy to maneuver in order to access fields with narrow gates.

Excellent Ground Following

To adapt to high mowing speeds: the positive angle movement of the mowing unit, connecting arms and the four flotation springs ensure superb ground following. The slotted linkage eliminates the need for a hydraulic float valve on the tractor.
