8.5 HYDRAULICS
The CA25 Combine Adapter’s hydraulic system
provides oil for the header draper and knife
drives as well as the adapter feed draper.
Reel hydraulics are provided by the combine.
8.5.1 Reservoir
The adapter frame is used as a reservoir.
Refer to Section 8.3.4 Recommended Fluids
and Lubricants for proper oil.
8.5.1.1 Oil Level
Check oil level every 25 hours at sights (A) and
(B) with cutterbar just touching ground. Check
when oil is cold, and with center-link retracted.
 Nominal - Normal Terrain: Maintain level
so lower sight (A) is full, and upper sight (B)
is empty.
 Maximum - Hilly Terrain: Maintain level
so lower sight (A) is full, and upper sight (B)
is up to one-half filled.
 Minimum - Level Ground: 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 higher.
NOTE
When ambient temperatures are
above 95°F (35°C), to prevent
overflow at breather under operating
temperatures, it may be necessary to
lower oil level slightly.
8.5.1.2 Adding Hydraulic Oil
