Chopper (General Information)

CAUTION: Do not let anyone stand behind the chopper while it is running. Combine engine must be off, key removed, and parking brake set before adjusting chopper.

Normal use wears the bottom of the chopper vanes to a sharp edge.

There are two combine configurations available when using a chopper:

• One with cob deflector (A), installed in the rear hood for use with all crops.
• One without cob deflector for use with small grain crops only.

There are three rotor configurations available for choppers:

• Regular
• Fine Cut (straight blades)
• Fine Cut, Wide Spread (paddle blades)

The optional fine cut choppers have twice as many blades as the standard chopper.

The fine cut chopper has straight blades with double edged sharpened blades, good where yields and tough straw crops are harvested with narrow 7.6 m (25 ft) or less headers.

The wide spread, fine cut chopper has paddle type blades. The wide spread chopper provides a spread width of 9.1 m to 9.7 m (30 ft to 32 ft), depending upon conditions, and is suited for those areas where wider header equipment or windrows are utilized.

IMPORTANT: If harvesting corn, chopper speed must be set at "low speed" (1200 rpm) to avoid damage to chopper housing, tailboard, and vanes.

There are two tailboard configurations available for use with choppers:

• Regular
• Wide Spread.

The widespread chopper tailboard vanes are twice as deep as the standard chopper vanes and capable of distributing straw residue over 9.1 m (30 ft.)
