SECTION 58 - DRIVELINES - CHAPTER 3
58-3
If a problem is found with a specific module, the
extent of the damage can be quickly determined by
removing the disc and the top cap assembly, 1, of the
affected module. If damage is limited to the top cap
assembly components, the lower module can be
flushed out to remove contaminants, and a new top
cap assembly installed to complete the repair.
The cutterbar uses small diameter, high profile discs,
which are 3/16 inch and hardened for long wear. The
profile of the discs provides a natural lifting action,
which helps fluff the cut crop for faster drying.
The discs are equipped with 2 inch wide knives,
which are retained with 1/2 inch bolts and hardened
knife nuts. The knives are reversible for long life, and
always have the beveled edge up. An arrow is
stamped on both sides of the knife to show the
direction of rotation.
Heat treated knife bolt protectors serve as a wear
surface to guard the bolt from deterioration, and can
be rotated to extend life. The knives can be easily
changed in any position on the cutterbar.
Each disc module is protected by a hardened ductile
iron rock guard and a skid shoe.
Skid shoes are 1/4 inch thick and 8 inch wide; they
extend behind the module several inches for
optimum flotation and extended wear life of the shoe.
