8.8 HYDRAULICS
The CA20 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.
8.8.1 RESERVOIR
The adapter frame is used as a reservoir.
Refer to Section 8.4, Recommended Fluids and
Lubricants for proper oil.
8.8.1.1 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
sight (A) is full and sight (B) is up to 1/2 filled.
Minimum – Level Ground: For slopes of 6° or
less, oil level may be kept slightly lower if
desired. Maintain level so sight (A) is ½ filled or
higher.
NOTE
When ambient temperatures are above
35° C (95° F), to prevent overflow at
breather under operating temperatures, it
may be necessary to lower oil level
slightly.
