Figure 3.30: Float Indicator
When calibrated properly, the float indicator pointer will react
to ground pressure as follows:
•
Pointer centered on number 2 (A):
header on level ground
in cutting position, normal ground pressure
•
Pointer above number 2:
header on ground, increased
ground pressure
•
Pointer below number 2:
header off the ground, decreased
ground pressure
Adjusting Float
The float setting (or lifting force) changes depending on the conditioner type and options. The setting must be the same at
both ends of the rotary disc header.
DANGER
To prevent bodily injury or death from the unexpected start-up or fall of a raised machine, stop the engine, remove the
key from the ignition, and engage the lift cylinder lock-out valves before going under the machine.
DANGER
Ensure that all bystanders have cleared the area.
NOTE:
Changing the rotary disc header
’
s operating position can affect the float settings. After adjusting the cutting height or the
cutterbar angle, check the float and adjust as necessary.
