Checking Header Float: M200 And M205 Windrowers - MacDon R85 Assembly Instructions Manual

4.2 Checking Header Float: M200 and M205 Windrowers

CAUTION
Check to be sure all bystanders have cleared the area.
1. Start engine and lower header to ground, and ensure
header lift cylinders are fully retracted.
2. Adjust the header angle/tilt to mid-range position with
the switches (A) and (B) on the windrower ground
speed lever (GSL).
3. Set the float fine adjustment to mid-range with the
windrower float adjustment system in the cab. Refer to
the windrower operator's manual.
DANGER
To avoid bodily injury or death from unexpected startup
of the machine, always stop the engine and remove the
key from the ignition before leaving the operator's seat
for any reason.
4. Stop engine, and remove key from ignition.
5. Check float by grasping the front corner of header and
lifting. The force to lift should be 426–471 N
(95–105 lbf), and should be approximately the same at
both ends.
6. Perform the following steps to adjust the float
(if necessary):
a. Start engine, and raise header fully.
b. Shut down engine, and remove the key.
c. Turn drawbolt (A):
•
Clockwise to INCREASE float
(make header lighter)
•
Counterclockwise to DECREASE float
(make header heavier)
d. Recheck the float.
