HEADER ATTACHING & DETACHING
ATTACHING HEADER TO COMBINE AND ADAPTER
1.Attach adapter to combine feeder housing. See "Adapter Mounting Instruction" at back of book. NOTE: If header has been previously attached to windrower, remove linkage supports from header lower legs. Connector shaft on header back tube may remain installed.
2.Choose an area that is as level as possible, and place supports (A) at both ends of cutterbar. For 962 Headers use 6" (150 mm) blocks. For 972 Headers use 2x4 (40 mm) blocks.
3.For 962 headers with gauge wheels, block both wheels front and rear, and be sure gauge wheel pins are in stand position (L), both sides, to support rear of header.
For 972 headers and 962 headers without gauge wheels, be sure header stand (B) is secure in the down position. For 962 Headers only, place a 4 inch (100 mm) block under stand.
BLOCK CUTTERBAR

CAUTION: Be sure area is clear of bystanders before starting engine.
4.Slowly drive combine forward, aligning float leaf springs under header legs, until top link can be connected. Connect top link (C).
NOTE: For headers with hydraulic top link, see instruction in “Unloading & Assembly” section.
CAUTION: Always connect top link before raising header.
IMPORTANT: Take care not to crush hydraulic hoses when driving into header.
IMPORTANT: For 972 Headers, when driving into header, align notches in adapter feed pan with retainers welded to cutterbar. Ensure that pan goes under the retainer and on top of cutterbar. The feeder house can be raised to lower the front edge of the pan, and vice versa. In soft ground conditions, a length of 2x4 under the pan will prevent scooping dirt
5.Raise adapter slowly, making sure float leaf springs engage in header legs. Continue to lift until header is fully raised. Stop engine and remove key.

DRAPER SPEED CONTROL
Speed of the header drapers is adjusted at the flow control on the combine adapter. Rotate flow control knob
(C) to a number suited to the crop. The higher the number, the faster the draper speed. The settings in the chart are recommended for optimum feeding capacity.
NOTE: If sufficient draper speed cannot be achieved, a possible cause is low relief pressure. See "Flow Control Relief Pressure" in Maintenance/Service section.
Needle Valve: When laying a windrow, turn needle valve control (B) fully open to stop flow to the feed draper and drum.
NOTE: Valve must be fully open to prevent rotation of feed draper and |

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 from 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 fore-aft position. For best float, gap at (A) should never exceed ¼ inch (6 mm).
4.With cutterbar 1 to 6 inches (25 to 150 mm) above the ground, grasp the crop divider rod and lift up. Under normal conditions it should require 50 to 70 lbs. force (220 to 310 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.Tighten bolts (B) at both sides of adapter to increase float (which makes header lighter when lowered to ground).
Loosen bolts 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 3rd leaf spring from the top on both sides of the adapter to provide proper floatation. See Unloading and Assembly section for removal instructions.
FLOAT ADJUSTMENT
15
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) off the ground.
2.Check level of header by measuring cutterbar to ground at both ends.
3.To lower cutterbar on one end, remove 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 remove 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 section 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 HEADER LEVELLING in down crop for better lifting action.
IMPORTANT: Always check adapter drum clearance to header frame after adjusting header angle. Flattening the header angle will reduce the clearance to the drum fingers.
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 adjustment
of header angle from the combine cab by means
of a hydraulic cylinder. HEADER ANGLE MECHANICAL ADJUSTMENT See “Unloading and Assembly” section for
information on assembly and use of this option.

OPERATION
WIDENING THE DELIVERY OPENING: Case, Gleaner & New Holland TR Combines:
In conditions where severe “bridging” is occurring (bulky crop being thrown across the opening), widen the header side draper opening to allow the crop to fall onto the feed draper. See “Delivery Opening” in your Header Operators’ Manual for procedure. To achieve smooth feeding after widening opening, add outboard tines to the adapter drum. See “Tine Installation”, page 24.

Assembled for Maximum Ground Clearance
Spacer plate (F) is factory assembled for best ground clearance, with plate (F) mounted to the forward set of holes in pan (G) as shown above left. When windrowing with the combine and in certain other conditions, clearances may be such that the header drapers catch on the deck or on angle (H). If so, move spacer plate (F) to rear set of holes in pan (G) as shown above right. To reposition spacer plate (F), proceed as follows:
•Remove two center bolts (K) and loosen bolts at outside ends of pan.
•Slide spacer out (forward) and slide it in from the back onto the loosened bolts.
•Replace the two center bolts, exchanging positions so the 1 ¼ bolt again goes through the spacer plate.
•Exchange positions of the bolts at outside ends of pan so the 1 ¼ bolts go through spacer plate.

MAINTENANCE/SERVICE
SEALED BEARING INSTALLATION
1.Clean shaft and coat with rust preventative.
2.Install flangette, bearing, flangette and lock collar. The locking cam is only on one side of the bearing.
3.Install and tighten the flangette bolts.
4.When the shaft is located correctly, lock the lock collar with a punch. The collar should be locked in the same direction the shaft rotates. Tighten the set screw in the collar.
5.Loosen the flangette bolts on the mating bearing one turn and re-tighten. this will allow the bearing to line up.

GREASING THE ADAPTER
See "Recommended Lubricants" in this section for recommended greases.
The adapter has four greasing points as shown on the following page. Use the hour meter in the combine cab and the "Maintenance Checklist" provided to keep a record of scheduled maintenance.
Procedure:
1.Wipe grease fitting with a clean cloth before greasing, to avoid injecting dirt and grit.
2.Inject grease through fitting with grease gun until grease overflows fitting.
3.Leave excess grease on fitting to keep out dirt.
4.Replace any loose or broken fittings immediately.
5.If fitting will not take grease, remove and clean thoroughly. Also clean lubricant passageway. Replace fitting if necessary.

MAINTENANCE/SERVICE
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 body 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.
•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.

HYDRAULIC SYSTEM (continued)
Hydraulic Oil
The combine adapter’s hydraulic system provides oil for the draper and feed drum drives.
Check oil level every 25 hours at dipstick (A). Maintain level between "LOW" and "FULL" marks when oil is cold.
Capacity:
-Full system: 25 litres (6.6 U.S. gallons)
-Tanks only: 17 litres (4.5 U.S. gals.)
Type – See recommended lubricants, page 18.
NOTE: When ambient temperatures are above 35º C (95º F), maintain oil level in the low portion of the range to prevent overflow at breather under operating temperatures.
Change hydraulic oil every 1000 hours or 3 years To change hydraulic oil:
1.Remove dipstick cap (A).
2.Remove plug (B) at right reservoir and hose (E) at left reservoir.
NOTE: A drain pan with a capacity of 15 litres (4 U.S. gallons) will be required for each reservoir.
3.Replace the hydraulic oil filter. See below.
4.Replace plug (B) and hose (E) and fill the reservoirs through female coupler (D) from a pressurized oil source.
NOTE: Do not use cap port (A) to fill system. Oil will not reach left reservoir. If a pressurized source of oil is not available, pump oil from right reservoir to left as follows:
•Fill R/H reservoir with oil through cap port (A).
•Run the adapter pump until feed drum stops turning.
•Re-fill R/H reservoir.
•Repeat procedure until oil level in R/H reservoir remains between LOW and FULL on dipstick.
5. Replace cap (A).
Hydraulic Oil Filter
Change hydraulic oil filter (C) after the first 50 hours operation and every 250 hours thereafter. To change:
1.Clean around the filter head.
2.Remove the filter and clean the gasket surface of the filter head.
3.Apply a thin film of clean oil to the gasket on the new filter.
4.Install the new filter. Turn the filter onto the mount until the gasket contacts the filter head. Tighten the filter an additional 1/2 to 3/4 turn by hand.
IMPORTANT: Do not use a filter wrench to install the filter. Over-tightening can damage gasket and filter.
