4.5 Checking Oil Level in Hydraulic Reservoir
Figure 4.5: Oil Level Sight Glass
1. Check oil level using lower sight (A) and upper sight (B)
with cutterbar just touching the ground.
NOTE:
Check level when oil is cold and with center-link
retracted.
2. Ensure oil is at appropriate level for terrain as follows:
• Hilly terrain (C): Maintain level so lower sight (A) is
full, and upper sight (B) is up to one-half filled.
• Normal terrain (D): Maintain level so lower sight (A)
is full, and upper sight (B) is empty.
• Level ground (E): For slopes of 6° or less, oil level
may be kept slightly lower if desired. Maintain level
so lower sight (A) is one-half filled or slightly higher.

3. Maintain level for normal terrain (D) so lower sight (A) is
full, and upper sight (B) is empty.
NOTE:
It may be necessary to slightly reduce oil level when
ambient temperatures are above 35°C (95°F) to prevent
overflow at breather when normal operating
temperatures are reached.
