4.5 Operating a Header
This section describes the operating instructions for the following header types when attached to a MacDon M1240
Windrower: A40DX Auger Header, D1XL Series Draper Header, D1X Series Draper Header, R113 or R216 Series Rotary Disc
Header.
4.5.1 Engaging and Disengaging Header Safety Props
Safety props are located on both header lift cylinders on the windrower. Engage the props any time you are going to work
on or around a raised header. When engaged, safety props prevent a header from dropping suddenly if the lift system
hydraulics lose pressure.
DANGER
To prevent bodily injury or death from the unexpected start-up or fall of a raised machine, always stop the engine and
remove the key before leaving the operator’s seat, and always engage the safety props before going under the
machine for any reason.
1. Start the engine.

If one end of the header does NOT fully rise, rephase the
lift cylinders as follows:
a. Press and hold HEADER UP switch (A) until both
cylinders stop moving.
b. Continue to hold the switch for 3–4 seconds. The
cylinders are now phased.
3. Shut down the engine, and remove the key from

4. Engage the safety props on both lift cylinders as follows:
a. Pull lever (A) toward you to release it, and then rotate
it toward the header to lower the safety prop onto the
cylinder.

IMPORTANT:
Ensure that the safety props engage over the cylinder piston
rods. If the safety prop does NOT engage properly, raise the
header until the safety prop fits over the rod.
