Revision A
Disabling Flex Frown Limiter
Disabling the flex frown limiter increases the flex range which can help the header follow ground contours on uneven
terrain, and may be preferred when a close reel-to-cutterbar relationship is not critical, such as when harvesting tall crops
like standing cereals or canola.
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.
NOTE:
When the flex frown limiter plate is removed, the reel to cutterbar clearance will not be able to be as close, and will
require adjustment. Refer to
4.13.1 Reel Clearance to Cutterbar, page 417
for specifications.
