6.4 Hydraulics
The CA25 Combine Adapter’s hydraulic system drives the adapter feed draper, side drapers, and knife drives. The
combine’s hydraulic system drives the reel hydraulics.
The adapter frame acts as an oil reservoir. Refer to the inside back cover for oil requirements.
6.4.1 Checking Oil Level in Hydraulic Reservoir
Check hydraulic oil level in reservoir every 25 hours.
Figure 6.29: 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.
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.
6.4.2 Adding Oil to Hydraulic Reservoir
Follow this procedure to top up the oil in the hydraulic reservoir. To change the hydraulic oil, refer to 6.4.3 Changing Oil in
Hydraulic Reservoir, page 368.
DANGER
To prevent bodily injury or death from the unexpected start-up of the machine, always stop the engine and remove the
