DRAPER SPEED CONTROL

OPERATION

HEADER FLOTATION IMPORTANT:

To avoid:

- frequent breakage of sickle components

- scooping soil

- soil build-up at cutterbar in wet conditions, set header float as light as possible without causing excessive bouncing.

To check header float:

1. Raise feeder house and engage lift cylinder

stops.

2. Be sure float lock out pins are removed f rom

position (C).

3. Disengage lift cylinder stops and lower header

so the cutterbar is 1 to 6 inches (25 to 150 mm) above the ground.

NOTE: When cutterbar is in the range from 0 to 16 inches (400 mm) off ground, float arm should touch or be within ¼ inch (6 mm) of angle at (A). If gap at (A) is greater than ¼ inch, float is set too light, causing the header to float up.

NOTE: Header gets lighter and gap at (A) increases when steepening header angle. Adjust float after changing header angle or reel f ore-aft position. For best float, gap at (A) should never

exceed ¼ inch (6 mm).

4. W ith cutterbar 1 to 6 inches (25 to 150 m m)

above the ground, grasp the crop divider rod and lift up. Under normal conditions it should require 50 to 70 lbs. force (220 to 300 N) to lift cutterbar off ground at either end. If adjustment is required, proceed as follows:

To adjust header float:

1. Raise feeder house and engage lift cylinder

stops.

2. Turn bolts (B) at both sides of adapter clock-

wise to increase float (which makes header lighter when lowered to ground). Turn bolts counter-clockwise to decrease float (which makes header heavier when lowered).

IMPORTANT: For 21 ft. 972 headers only. If header still has excess float with float adjustment bolt fully backed off, it may be necessary to remove the 3 the top on both sides of the adapter to provide proper floatation. See Unloading and Assembly section for removal instructions.

FLOAT ADJUSTMENT

OPERATION

HEADER LEVELLING

Adjust header levelling with header at the flattest angle. See Header Angle, below.

1. With header on level ground, lower header so

cutterbar is 2 to 4 inches (50 to 100 mm) of f the ground.

2. Check level of header by measuring cutterbar to

ground at both ends.

3. To lower cutterbar on one end, re move a shim (C)

from between rubber pads (D) and angle (E). Adjust shim quantity side to side, placing from 0 to 2 shims to level header. To add or rem ove a shim:

• Lower cutterbar to ground and continue lowering

feeder house so gap at (A) increases.

• Remove nut (F) and add or remove shim (s) as

required.

• Reassemble, maintaining 1/8 inch (3 mm)

between angle and float support as shown.

HEADER ANGLE

The header (or guard) angle can be adjusted from 15° to 20° below horizontal. (Actual angle may vary with combine set-up.) See Combine Operator’s Manual for header levelling and additional header angle adjustments.

IMPORTANT: The flat header angle (15°) is recommended for normal conditions. A flatter header angle reduces sickle sec tion breakage and reduces soil scooping or build-up at the cutterbar in wet conditions. Use a steeper angle to cut very close to the ground, or in down crop for better lifting action.

IMPORTANT: Header flotation gets lighter as header angle increases, and must be readjusted. See "Header Flotation", on page 15.

To adjust header angle with mechanical link:

1. Lower cutterbar to ground and continue

lowering to drop feeder house another 2 to 5 inches (50 to 125 mm).

2. Back off the locking collar (A) on top link

turnbuckle.

3. Using a punch in hole in turnbuckle (B), turn to

adjust header angle.

Longer top link = steeper header angle

( = lighter float )

4. At desired adjustment, tighten locking collar (A)

securely against turnbuckle to fix the position.

HEADER ANGLE HYDRAULIC ADJUSTMENT

An optional kit is available which allows a djustment of header angle from the c om bine cab by means of a hydraulic cylinder. See “Unloading and Assembly” section for information on assembly and use of this option.

HYDRAULIC SYSTEM

Hydraulic Hoses and Lines

Check hydraulic hoses and lines daily for signs of leaks.

WARNING: Avoid high-pressure fluids. Escaping fluid can penetrate

the skin causing serious injury. Relieve pressure before disconnecting hydraulic lines. Tighten all connections before applying pressure. Keep hands and bo dy away from pinholes and nozzles that eject fluids under high pressure. Use a piece of cardboard or paper to search for leaks. IF ANY fluid is injected into the skin, a doctor familiar with this type of injury must surgically remove it within a few hours or gangrene may result.

IMPORTANT:

• Ensure all hydraulic couplings are fully

engaged before operating header.

AVOID HIGH PRESSURE FLUIDS

• Keep hydraulic coupler tips and connectors

clean. Dust, dirt, water and foreign material are the major causes of hydraulic system damage.

• To prevent improper mixing of oils:

If header is to be switched back and forth from combine to windrower, change oil in windrower tractor (or Bi-Directional Tractor) hydraulic system to match combine hydraulic system.
