On-the-go hydraulic drive of  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 (header drive reversing requires valve on SP tractor and is only available on M205 and M155 models) • Cam forward reel tine control reduces loading on bearings and cam-track for quieter operation and longer life • Highly durable poly auger pans for improved crop flow and reduced dirt build up and rock damage • N-bar non-contact steel conditioner rolls for optimum conditioning action • Optional double windrower attachment

SIZES • 14 ft. (4.3 m) • 16 ft. (4.9 m) • 18 ft. (5.5 m)

Wide Conditioner Rolls

A full 102" (2590 mm) wide, the A Series conditioner rolls provide extra width and increase the amount of crop in contact with the rolls. This improves crimping performance and ensures thorough conditioning of the loading on bearings and cam-track for quieter operations. A40 D Grass Seed plant stem. The use of steel on steel intermeshing roll design ensures that leaves are retained for high protein value providing high quality hay, forage and alfalfa crops.

Triple Placement            154 ft. (16.5 m)

1 Triple placement is possible with installation of GPS Auto Steer on your Windrower

Skid Shoes Option

Improves the placement of the cutterbar in relation to the ground, thereby reducing wear on the cutterbar and enhancing the in field performance of the header.

Stub Guard Option

Stub guards mount directly to the cutterbar to improve cutting performance in tough, stringy grass type crops, and crops that need to be cut close to the ground (such as grass, hay, and rice). Kits can be ordered based on size of product.

Gauge Roller Option

Attached behind the cutterbar to reduce wear on the cutterbar wear plate and improve the movement of the header over uneven terrain, as well as in sand or firm soil conditions. Optional for A and 16' R Series.
