MAINTENANCE/SERVICE
Hydraulic System
HYDRAULIC OIL
Change hydraulic oil every 2000 hours.
NOTE FOR FLEET OWNERS: If you also operate
an older MacDon built windrower tractor with a
production year ’99 or earlier, that unit’s hydraulic
system will be filled with 10W30 engine oil. It is
recommended that the change be made to single
grade trans-hydraulic oil at the next scheduled oil
change. See page 59 for recommended brand
names.
To change:
1. Remove drain plug (B) from bottom of reservoir.
Allow oil to drain.
NOTE: A drain pan with a capacity of 20 U.S.
gallons (75 litres) will be required.
2. Replace the hydraulic oil filter. See "Hydraulic
Oil Filters" in this section.
3. Clean off any metal debris which may have
accumulated on magnetic drain plug. Replace
plug (B).
4. Fill the system with oil through the filler neck.
See "Fuels, Fluids and Lubricants" page 59 for
recommended oil type. Check oil level with
dipstick periodically during filling to prevent spill-
over.
CAPACITY:
Reservoir only: 15.2 US gal. (57 litres)
Total system: approximately 17 US gal.
(65 litres)(varies with options)
HYDRAULIC OIL FILTERS
Change hydraulic oil filters after the first 10 hours
of operation and every 300 hours thereafter.
• Filter (A) is located at right side of engine
compartment, under side panel.
• Filter (B) is located just ahead of frame cross
channel, near hydrostatic pump.
To change:
1. Clean around the filter head.
2. Remove the filter element and clean the gasket
surface of the filter head.
3. Apply a thin film of clean oil to the gasket on the
new filter.
4. Install new filter. Turn the filter onto the mount
until the gasket contacts the filter head. Tighten
the filter an additional 1/2 turn by hand.
IMPORTANT: Do not use a filter wrench to install
the oil filter. Over-tightening can damage gasket
and filter.
