Header Float - MacDon R113 Operator's Manual

3.4 Header Float

The M1170 and M155E4 windrowers have different float adjustments. Although they both have float springs, the
M1170 is completely adjustable from the cab through the Harvest Performance Tracker (HPT) and the M155E4 has
coarse adjustment done at the spring drawbolt and fine adjustment done through the Cab Display Module (CDM) in
the windrower cab.
The header float feature allows the header to closely follow ground contours and respond quickly to sudden
changes or obstacles. The float setting is ideal when the cutterbar is on the ground with minimal bouncing,
scooping, or pushing soil.
IMPORTANT:
• Set header float as light as possible—without excessive bouncing—to avoid frequent breakage of knife
components, scooping soil, or soil build-up at the cutterbar in wet conditions.
• Avoid excessive bouncing (resulting In a ragged cut) by operating at a slower ground speed when the float
setting is light.
• Install applicable header options (skid shoes, etc.) before setting header float. If the slow speed transport (SST)
tow bar will be stored on header during operation, set float with tow bar in place.
• Adjust the float when adding or removing optional attachments that affect the weight of the header.
For instructions for setting and adjusting the header float, refer to your windrower operator's manual.
