ADJUSTING AND OPERATING
BLADE CARE
The cutting blades must be kept sharp at all
times. The blades can be sharpened on the
mower with a few strokes of a file or they can
be removed from the mower and sharpened on
a grinding wheel.
Note:
Sharpen ends evenly so
that the blades remain balanced. However, if
the cutting edge of a blade is within 3/8'inch of
the wind wing, it is recommended that new
blades be installed. New blades are available
at your IH dealer.
Flats are provided on outside pulleys to
keep spindles from rotating when blade nuts
are removed. A hole is provided in center
pulley and housing so a screw driver can be
used to keep the center spindle from rotating.
When replacing the blades, be sure they
are assembled on the friction discs so the cut¬
ting edges are in the direction of rotation with
the wind wings pointed upward and the cap
screws tightened securely.
Note: If the spindle nuts ore removed for any reason,
they should be retightened to 55 to 60 footpounds torque
when reploeed.

For best results it is recommended that the
first two laps should be cut with the discharge
being thrown towards the center. After the
first two laps, reverse the direction to throw
the discharge to the outside for the balance of
cutting. This will give a better appearance to
the lawn.
See
11 lust. 43.
Do not cut the grass too short, as it will
give a scalping effect and invite weed growth.
GENERAL
After 4 hours of running, check and adjust
for V-belt tension. Refer to "V-BELT AD¬
JUSTMENT'^
on poge 42.
After the first 10 hours of operation check
and retighten, if necessary, all nuts and bolts
on the machine paying particular attention to
the hex. nuts securing the blades to the spindles
and the cap screws at the top of the spindle.
These nuts and bolts should be tightened se¬
curely. Check and retighten, if necessary, all
nuts and bolts at least once a year thereafter.
Attaching ond Defaching the Mower
To facilitate changing of the blades, sharp¬
ening of the blades, cleaning, etc. , the mower
may be detached from the tractor in the follow- •
ing manner:
Pull out the left and right spring loaded sup¬
port pins "15" and turn them downward so ends
butt against support brackets "2".
Move mower forward so left and right sup¬
port clevises "3'' are free of the front pivot
links and lower mower to ground. Remove the
V-belt from the center pulley.
Pull tractor lift handle "8" back to raise the
lift linkage for clearance.
Slide the mower out from under the tractor
on the right side. To aid in removing the
mower, turn the tractor front wheels to the
right.
To attach the mower to the tractor, reverse
the above procedure.
SAFETY SUGGESTIONS
The discharge shield on the 48-inch mower
must be attached at all times while operating
the mower.
Children should not be allowed to operate the
mower unless properly supervised.
Never place hands or feet under the mower,
in the discharge chute, or near any moving
parts while the tractor engine is running. Do
not work on the mower with the engine running.
Never leave the tractor engine running un¬
attended or permit it to be operated by persons
not acquainted with its use and the rules for
safe operation.
Be sure all stones, branches^ or other ob¬
jects that might be picked up and thrown by the
mower blades are removed before starting to
mow.
Do not allow anyone in the area opposite the
discharge chute while mowing. Although the
area has been supposedly cleared of foreign ob¬
jects, small objects may have been overlooked
and may be discharged by the mower.
Disengage the power take-off clutch before
starting the tractor.
