Maintenance
As with any hydraulic system, contamination is
the most common cause of performance prob-
lems and pre-mature wear. Make a special effort
to properly clean quick couplers prior to attaching
the hoses to tractor.
1. Filter: All fluid is filtered through the high pres-
sure filter (PN 18574) and it will provide pro-
tection to the hydraulic components of your
drive if properly maintained. It is equipped
with a pop-out indicator to alert that the re-
placeable element is clogged, and should be
changed immediately if this situation occurs.
Normal service life of the element will vary
based on the precautions that you take to
minimize contamination at the couplers and
routine service of the tractor filtration.
To change the element:
Refer to Figure 131
1. Un-screw lower canister from filter, catching
and disposing of used fluid.
2. Remove and discard element.
3. Install new element (PN 19856)
4. Clean canister threads and lube o-ring with
hydraulic fluid, then re-install.
Refer to Figure 132
5. Re-set pop-out indicator if necessary.
It is a good idea to keep a filter element on hand,
and we recommend changing at a minimum on an
annual basis.
6. Between planting seasons, store cab console
inside in a relatively stable and dry environ-
ment.
7. Avoid direct spray from high pressure wash-
ers on the motor encoder and the external
controller box. These units are sealed from
normal moisture, but high pressure could in-
ject water into the housing.
8. Keep electrical connects free from dirt and
grease. It’s a good idea to occasionally spray
the terminals with contact cleaner to ensure
proper connection.
