Maintenance
Daily Lubrication or 8 hours
•
Grease - PTO Joint Bearings
•
Grease - PTO Shield Bearings
•
Check Oil Level in Gearbox add 80w90 Gear oil. Fill until oil reaches top mark on dipstick
or begins to flow out side plug hole in gearbox.
Important:
Do not overfill gearbox with oil! Oil will expand when hot! Make sure cutter is
level and oil is cool before checking oil level.
Weekly Lubrication or 40 hours
•
Grease - Wheel Bearing
•
Grease - Wing hinges, Hitch pivot points, Wheel beam hinge points.
•
Check for wear on Blade Bolts
•
Check for wear and cracks around Blade Pivot Hole
Annually
•
Wash and cleanup
•
Touch up any paint scratches
•
Store on blocks of wood in a dry place
Lubrication
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
See below chart for lubrication points and frequency or lubrication based on normal operating
conditions. Severe or unusual conditions may require more frequent lubrication. Be sure to clean
fittings thoroughly before attaching grease gun. One good pump of most guns is sufficient when
the lubrication schedule is followed.
Slip Clutch Adjustment
The slip clutch is designed to slip so that the gearbox and driveline are protected if the cutter
strikes an obstruction.
A new slip clutch or one that has been in storage over the winter may seize. Before operating
the cutter, make sure it will slip by performing the following operation:
•
Remove driveline from tractor PTO.
•
Loosen six 10 mm cap screws to remove all tension from Belleville spring plate.
•
Hold clutch hub solid and turn shaft to make sure clutch slips.
•
If clutch does not slip freely, disassemble and clean the thrust plate faces, flange yoke, and
clutch hub.
•
Reassemble clutch.
•
Tighten Belleville spring until it is against the thrust plate of the clutch, and then back off each
of the six nuts by 2 full revolutions. The gap between Belleville spring and thrust plate should
be 1/8"
•
If a clutch continues to slip when the spring is compressed to 1/8" gap, check friction discs
for excessive wear. Discs are 1/8" when new. Replace discs after 1/16" wear. Minimum disc
thickness is 1/16".
