Checking Oil Level
Check oil level every 25 hours at lower (A) and upper (B)
sights with cutterbar just touching ground.
Check level
when oil is cold, and with center-link retracted.
• Maximum - Hilly Terrain (C): Maintain level so lower
sight (A) is full, and upper sight (B) is up to one-half filled.
• Nominal - Normal Terrain (D): Maintain level so lower
sight (A) is full, and upper sight (B) is empty.
• Minimum - Level Ground (E): For slopes of 6 degrees
or less, oil level may be kept slightly lower if desired.
Maintain level so lower sight (A) is one-half filled or
slightly higher.
NOTE:
When ambient temperatures are above 95°F
(35°C), it may be necessary to lower oil level
slightly to prevent overflow at breather under
operating temperatures.
