FLOAT LOCKOUT FLOAT ENGAGED ADAPTER FLOAT 2.
OPERATION 963/972/973 HEADER FLOTATION (continued) When working with cutterbar on ground (e.g. soybeans): • • • • • • • • Set top link length to mid-range position, 19-1/4” (490 mm). Set float arm gap to 1/2” (13 mm) as described on previous page. Best float operation will occur with minimum extra weight on header. Consider removing gauge wheels or transport attachments, if equipped. Adjust float optimizer (if equipped) or feeder house height while watching float indicator to set cutterbar down force.
OPERATION 963/972/973 HEADER FLOTATION Header Floatation for 963 Headers with Gauge Wheel/Transport Wheel (continued): 3. Position the header at desired cutting height with gauge wheel pins install in the appropriate position. At this position inspect the gap at (B) to ensure that the gauge wheel springs are not pushing the header off the float down-stop pads. If this is true proceed to step 4. If gap at (B) is between 0 to 1/2 inch (0 to 13 mm) proceed to step 4.
OPERATION 963/972/973 HEADER FLOTATION (continued) Header Floatation for 972/973 Headers with Gauge Wheel/Transport Wheel: 1. Set guard angle and reel to desired position for cutting conditions and slide handle (A) down to engage float. 2. Lower header to remove the pins from the gauge wheels A 3. Position the header at the desired cutting height (without gauge wheel pins in).
OPERATION HEADER LEVELLING NOTE: The following applies if gap (A) is zero. If float is set light (operating cutterbar on ground), then level header by adjusting main float springs. Adjust header levelling with header at the flattest angle. See Header Angle, next page. 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.
OPERATION HEADER ANGLE The header (or guard) angle can be adjusted flatter or steeper to suit your conditions. Angle range varies with combine set-up, tire size, adapter down stop position, etc. See Combine Operator's Manual for header levelling and additional header angle adjustments. For combines with adjustable face-plate angle, see “Adjustments and Checks” on page 50 to determine if adjustment to face plate angle is required. IMPORTANT: A flat header angle is recommended for normal conditions.
OPERATION WINDROWING WITH THE COMBINE When laying a windrow, stop flow to the feed draper and drum as follows: • Remove hose (A) at pump (inboard port). • Remove hose (B) at hydraulic line. • Connect hose (B) (removed at hydraulic line) to open port at pump using connector hose listed below. • Connect hose (A) (removed at pump) to hydraulic line using male union listed below. NOTE: The following parts will be required to make the new connections: Part No. 33422 Hose and Part No. 30558 Male Union.

Wait for all moving parts to stop. 6. Park on level surface when possible. Block wheels securely.
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. TIGHTEN COLLAR IN DIRECTION SHAFT ROTATES 5.
MAINTENANCE/SERVICE GREASING THE ADAPTER 100 Hours or Annually (continued): 2. Feed Draper Idler Roller Bearings (C) – two fittings. Replace bearings every 500 hours or annually. 4. Lower Link Pins (E) – four fittings (two per side) C E LOWER LINK PINS – REAR OF ADAPTER FEEDER DRAPER IDLER ROLLER BEARINGS 3. Feeder Draper Drive Roller Bearing (D) – one fitting at right end of roller NOTE: To avoid damage to bearing seal, when greasing drive roller bearing use a single slow stroke of grease gun.
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.
MAINTENANCE/SERVICE 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: 33 litres (8-3/4 U.S. gallons) Tanks only: 27 litres (7-1/8 U.S. gallons) Type: See recommended lubricants, page 25.
MAINTENANCE/SERVICE HYDRAULIC SYSTEM (continued) Flow Control Relief Pressure The valve on the combine adapter has three relief valves for the following functions: (R1) – 3500 psi (24.1 Mpa) – Feed Draper and Drum in reverse. (R2) – 3200 psi (22.1 Mpa) – Feed Draper and Drum in forward. (R3) – 2500 psi (17.2 Mpa) – Header Side Drapers. A possible cause of insufficient draper/drum speed is low relief pressure.
MAINTENANCE/SERVICE HYDRAULIC SYSTEM (continued) To check sequence valve operation: If adapter drum and feed draper circuit relief pressures check out to specification as described on previous page, but these pressures are not reached under field operating conditions, check the operation of the sequence valve (A) in the valve block as follows: 1.
MAINTENANCE/SERVICE RETRACTING TINE DRUM Tine Pitch Adjustment – Tines should be fully extended on the front side of the drum and full retracted on the rear (feeder house) side. Tine pitch can be adjusted to change the aggressiveness of the tines. More aggressive tine pitch means the tines stay extended for longer as they approach the feed chain on the combine. Less aggressive means the tines retract sooner.
MAINTENANCE/SERVICE MAINTENANCE SCHEDULE The following maintenance schedule is a listing of periodic maintenance procedures, organized by service intervals. For detailed instructions, see the specific headings in Maintenance/Service section. Use “Recommended Lubricants” as specified under that heading. Service Intervals The recommended service intervals are in hours of operation. Use the hour meter in the combine to indicate when the next service interval has been reached.
