Hydraulic Drive Maintenance
As with any hydraulic system, contamination is the most
common cause of performance problems and
pre-mature wear. Make a special effort to properly clean
quick couplers prior to attaching the hoses to tractor.
Filter: All fluid is filtered through the high pressure filter
(p/n 18574) and it provides protection to the hydraulic
components of your drive if properly maintained. It is
equipped with a pop-out indicator to alert that the
replaceable 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 124
1.
Un-screw lower canister from filter, catching and
disposing of used fluid.
2. Remove and discard element.
3. Install new element (p/n 19856)
4. Clean canister threads and lube o-ring with hydraulic
fluid, then re-install.
Refer to Figure 125
5.
Re-set pop-out indicator if necessary.
It is a good idea to keep a filter element on hand, and
Great Plains recommends changing filters annually, if not
more often.
• Between planting seasons, store cab console inside in
a relatively stable and dry environment.
• Avoid direct spray from high pressure washers on the
motor encoder and the external controller box. These
units are sealed from normal moisture, but high
pressure could inject water into the housing.
• 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.
