Hydraulics
The float module frame acts as an oil reservoir. Refer to the inside back cover for information on the float module
’
s oil
requirements.

Checking Oil Level in Hydraulic Reservoir
Check the hydraulic oil level in the reservoir every 25 hours.
NOTE:
Check the level when the oil is cold.

Figure 4.32: Oil Level Sight Glasses
1.
Check the oil level using lower sight (A) and upper sight (B)
with the cutterbar just touching the ground and with the
center-link retracted.
2.
Ensure the oil is at the appropriate level for the terrain as
follows:
•
Normal terrain (1):
Maintain level so lower sight (A) is
full, and upper sight (B) is empty.
•
Hilly terrain (2):
Maintain level so lower sight (A) is full,
and upper sight (B) is up to one-half filled.
NOTE:
It may be necessary to slightly reduce the oil level when
ambient temperatures are above 35°C (95°F) to prevent
overflow at the breather when normal operating
temperatures are reached.
NOTE:
It is
OK
to use the hilly terrain oil level even in normal
terrain as long as the fill neck extension is installed
(MACB6057).
4.4.2
Adding Oil to Hydraulic Reservoir
If the oil level in the hydraulic reservoir is low, or if the oil has been drained, oil will need to be added.
DANGER
To prevent injury or death from the unexpected start-up of the machine, always stop the engine and remove the key
from the ignition before leaving the operator
’
s seat for any reason.
