18' Features & Benefits

BUILT TOUGH TO DELIVER A CLEAN CUT

We’ve made the cutterbar exceptionally strong, with its Z-shaped profile and rectangular reinforcements. With a cast housing for the dual Wobble Boxes and rugged internal components of the knife drive system, the A Series delivers a consistent clean cut in a wide range of crop conditions.

SMOOTH CROP FLOW

On-the-go adjustment for the hydraulic drive reel, sickle, auger, and conditioner allows the operator to be in full control of all aspects of hay and forage harvesting from the operator’s seat. Crop flow happens smoothly, even under adverse conditions, thanks to the combination of MacDon’s poly feed pan design, progressive feed paddles, and stripper bar arrangement.

DOUBLE WINDROW ATTACHMENT

MacDon’s Double Windrow Attachment (DWA) allows you to place up to 16.5 m (54') of crop into a single windrow by combining three 5.5 m (18') conditioned windrows. Ideal for today’s large forage harvesters. Adding this option can translate into significant time and fuel savings in the field.

SERIOUS CONDITIONING

A Series Auger Headers are equipped with wide conditioner rolls for increased crop contact, improving crimping performance and ensuring thorough conditioning of the plant stem. The steel-on-steel n-bar intermeshing roll design helps retain leaves, which is important for high protein values and making high-quality feed.

PRECISION CONTROLS EQUAL PERFORMANCE CONTROL

The new two stage controls allow for faster and more precise positioning of the header lift. Users can easily program up to three One-Touch-Return buttons for fast in-field control of the header’s height, tilt, knife speed, and reel/auger speed.
