4.6 Operating Header
This section describes the operating instructions for the following header types when attached to a MacDon M1170 NT5
Windrower: D1XL Series Draper Headers and D1X Series Draper Headers.
A variety of header options and attachments are available for use on headers powered by an M1170 NT5 Windrower. Refer
to the header operator
’
s manual for a list of available options and attachments.
4.6.1 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.
WARNING
Check to be sure all bystanders have cleared the area.
1. Start the engine.
