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.
1) Filter --All fluid is filtered through the high pressure filter (PN 18574) and it will
provide 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. (See Figures 34 and 35)
To change the element:
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.
5) Re-set pop-out indicator if necessary. (See Figure 35.)
It is a good idea to keep a filter element on hand, and we recommend changing
annually, and more frequently in high-acreage usage, and in conditions prone to
contamination.

2) Between planting seasons, store cab console inside in a relatively stable and
dry environment.
3) 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.
4) 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.
