Page 3: Introduction
INTRODUCTION Your new 973/974 Header is specially designed as a “straight cut” header, to be attached to your combine using a model 873 Adapter. These headers are equipped to work well in all straight cut conditions, whether cutting on or above the ground. When weather is not a critical factor, straight cutting eliminates the windrowing operation. -

Page 22: Divider Rod Length
OPERATION DIVIDER ROD LENGTH Divider rods are removable and two lengths are provided as standard equipment. The longer rods (A) are suitable when crop requires running down, while the shorter pointed rods (B) are better in standing crops. See the chart below for recommended rod length for various crops. -
Page 23: Ground Speed
OPERATION GROUND SPEED • Ground speed should be such that the sickle can cut crop smoothly and cleanly, while giving the desired delivery of material to the opening. Excessive ground speed results in "ragged" cutting. • In tough-to-cut crops like flax, reduce ground speed to reduce loads on cutting components and drives. •... -
