ADJUSTING/REMOVING CROP DEFLECTOR

INITIAL SET-UP

PREPARING THE HEADER

Tractor is positioned at header center delivery opening. A center delivered windrow goes under the tractor.

Windrow width and height are limited by tractor tire tread width and tractor frame height.

Headers with hay conditioner: Cab end tire tread width must be 88” (2235 mm) center to center to clear hay conditioner shield.

Headers with Reel Lift: Extend reel lift hose by removing existing coupler and replacing it with hose and coupler supplied with adapter.

970 Series Headers: For 21’ to 36’ headers, the sickle drive assembly at left end sheet and drive shaft along left side of back tube must be in “Windrower” configuration (in upper of two positions). If conversion from

“Combine” configuration is necessary, order the following conversion kit:

21’ – B2620, 25’ – B2621, 30’ – B2622, 36’ – B2623. Instructions are provided with the kit.

The illustration below shows the maximum delivery opening width (distance between rollers) and clearances with tractor tire tread width set at 79 inches (2000mm). This is the minimum tread width recommended for the

802 Adapter. Tractor tire to windrow clearance can be increased by changing the tread width. Keep in mind that crop may fan out as it leaves the header. Allow enough clearance to prevent tires running over the windrow.

NOTE: Delivering bushy crops like canola under the tractor may cause poor windrow formation due to restricted under-tractor clearance.

OPERATION

HEADER CONTROLS

WARNING: To avoid injury caused by unexpected movement of reel and/or conveyor, always disengage the blue hydraulic circuit before shutting the engine off. Reel and conveyor will move if engine is started with blue circuit engaged.

Blue Hydraulic Control Lever – Engage blue hydraulic circuit before engaging the PTO or auxiliary pump.

The blue circuit provides oil for the reel and conveyor drives and supercharges the PTO mounted MacDon pump if equipped. Set flow to 18 gallons per minute (except for Model 910 Series Headers set to 8 gpm). If a flow meter is not available, set the flow as follows:

All except 910 Series Headers:

• Set reel and conveyor speed to maximum.

• Increase flow in blue circuit until reel and/or conveyors no longer increase in speed.

For 910 Series Headers only, set pressure (at operating temperature) to read 50 psi (345 kPa) at coupler with yellow cable tie.

PTO Clutch (units with MacDon Header Drive Pump) – After engaging the blue hydraulic circuit, engage the

PTO clutch to start the sickle drive.

IMPORTANT: To prevent damage to the pump, blue hydraulic circuit must be on before PTO is engaged.

Auxiliary Pump Switch (TV140 Tractors with New Holland Auxiliary Pump) – After engaging the blue hydraulic circuit, turn auxiliary pump switch to ON to start sickle drive.

IMPORTANT: Set flow to 25 gallons per minute. If a flow meter is not available, adjust flow until sickle drive shaft speed is 1100 rpm, measured at the rear (driver) pulley inside left end sheet of header. Damage to sickle drive motor seal may occur if flow is set too high.

Green Hydraulic Control Lever - Controls the header lift on all header models.

Tan Hydraulic Control Lever - Controls the reel lift on 942 and 970 Series header models.

Green and Tan Flow Control Dials - Control the lift/lower rate of the header and reel respectively. Set to operator preference. NOTE: If flow to green and tan circuits is set too high, blue circuit flow may be reduced.

See Tractor Operator’s Manual for location and operation of the above controls.

Reel Speed - Press plus (+) side of switch (B) to increase reel speed and minus (-) side to decrease. See header Operator’s Manual for speed range.

Conveyor Speed - Press plus (+) side of switch (C) to increase conveyor speed and minus (-) side to decrease. See header

Operator’s Manual for speed range.

OPERATION

HEADER LEVELLING

NOTE: Adjust header level before adjusting header flotation.

To level header:

1. Ensure pins (G) are at the top of slots in bars

(F) on both sides.

2. Loosen off jam nut on header levelling bolt (E).

Access to nut is through slot (D).

3. Adjust bolt (E) until header is level.

4. Tighten jam nut to secure the position.

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.

Ensure float indicator (C) is at bottom of gauge and stays in the 0 – 3 range during operation.

Damage to header and adapter may occur when operating above 5 on the gauge.

Float settings vary with header type. For draper headers under normal conditions, adjust float spring tension so 50 to 70 lbs. force (220 to 300 N) is required to lift cutterbar at each end. See recommended float setting in your Header

Operator’s Manual.

To adjust header float on adapter:

1. Lower cutterbar to the ground.

2. Loosen springs, if required, so that both working pins (A) are tight in the slots as shown.

NOTE: The slots provide the float range. Pin

(A) is shown at the bottom of the float range.

3. Tighten bolts (B) (two per side) to increase float

(which makes header lighter at cutting height).

Loosen bolts to decrease float (which makes header heavier at cutting height).

NOTE: Both springs on one side should be adjusted equally (same exposed bolt length).

Due to weight differences side-to-side, adjustments will differ from one leg to the other.

4. When adjustment is complete, force required to lift cutterbar should be approximately the same at both ends. Check that both pins (A) are tight in the slots, as shown, with the pin against the bottom of the slot in adapter frame, and against the top of the slot in vertical link (V). If not, springs have been over-tightened, and should be loosened to provide proper float.

NOTE: To determine if header is floating at cutting height, check for clearance between pin

(A) and the bottom of slot in vertical link (V). If there is no clearance, header is not floating.

OPERATION

HEADER ANGLE

Header angle is adjustable by changing the length of the center link between header and adapter.

See header Operator’s Manual for header angle adjustment ranges.

IMPORTANT: A flatter header angle is recommended for normal conditions. A flatter angle reduces sickle section breakage and reduces soil build-up at the cutterbar in wet conditions.

A steeper header angle is recommended when using a hay conditioner, when cutting very close to the ground, or for better lifting action of down crops.

NOTE: Center link is shown mounted in lower of two positions. Use the top mounting holes only for

970 Series Headers without hay conditioner. Use lower hole for all other Header/Attachment combinations. If top hole is used for 970 Series

Headers with hay conditioner, damage to conditioner shield and pump may occur.

To adjust header angle:

1. Unlock collar (C) by tapping it in a counterclockwise direction.

2. Using a long punch in hole (D), turn the center link until the desired header angle is reached.

Shortening the link will give a flatter header angle, while lengthening the link provides steeper angles.

3. Lock collar (C) against link body by tapping in a clockwise direction to secure the position.

Headers with 721/742 Hay Conditioner

(910/920 Series Auger Headers)

To provide proper clearance between hay conditioner forming shields and pump on tractor

PTO, shield height must be adjusted to suit header angle.

Mount shields in top hole (A) for flat header angle and bottom hole, as shown, for steep header angle.

To compensate for small changes in header angle; shield position with respect to hay conditioner can be adjusted by repositioning hardware in slot (B).

HYDRAULIC SYSTEM

Hydraulic Hoses - Check daily for leakage.

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 which eject fluids under high pressure. Use a piece of cardboard or paper to search for leaks. IF ANY fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type of injury or gangrene may result.

IMPORTANT:

• Ensure all hydraulic couplings are properly mated and fully engaged before operating header.

• To avoid wasting oil, do not direct more flow to the header drive hydraulic circuit than can be handled by the adapter flow control (maximum

18 GPM). See "Header Controls" in Operation section.

• 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

Bi-Directional tractor, change oil in tractor hydraulic system and in combine adapter hydraulic reservoir to match combine system.
