-Telescoping Tubes: Every 4 hours. Apply grease to the collar located at the middle of the shaft. The
grease fitting on this collar will come exposed when the cutter wings are laying flat.
Occasionally (monthly) pull the universal joint halves apart and apply grease to all sides of the slip shaft.
At least once per year (more often in dusty or dirty conditions) the shielding should be removed and the
old grease removed with a solvent. A fresh coat of grease should then be
applied to the entire surface of the inner tube.
IMPORTANT: If the universal joint sliding members are allowed to dry out to the point where two halves
cannot slip freely, damage to the rotary cutter or tractor may occur.
-Rapid Fit Yoke: Every 2 days.
Cutter Frame
-Frame Pivot Points: Every 8 hours, locations listed below:
(1) Hitch swivel (1) Main lift
(2) Hitch Frame(4) Wheel Standards
-Wheel Hubs: Every 50 hours, 6 locations. Fill until grease is seen purging at the pivot bearing
seals.
STORAGE
Clean any dirt or debris off the mower deck.
Scrape any accumulated cuttings off the under side of the deck.
Coat the deck underside and any other exposed metal surfaces
with oil to prevent rusting.
If the mower is left unused for an extended period of time, install
the transport pins. Disconnect the hydraulic cylinders at the rod
end retract the rods for storage. Retracting the cylinder rods will
prevent rusting, ensure that the cylinders are full of oil, and relieve
pressure in the hydraulic circuit. If the cylinder rods are not
retracted smear grease over exposed hydraulic cylinder rods.
Apply grease to exposed threaded adjustment screws. These include the cylinder depth stop collar and
the frame leveling rod.
Spring adjustable slip clutches should be removed from the
machine and stored inside.
Install the hitch jack on the jack mount located on the outer hitch
frame.
When disconnecting from the tractor for a short period of time,
swing the PTO support upright and lay the PTO driveline into the
cradle. When storing the mower for an extended period of time, it
is recommended the driveline be removed from the machine and stored inside.When connecting the mower
to the tractor, ensure the PTO support is swung down, and out of the way.
