Your new rotary mower is designed to meet
today's exacting operating requirements. The
ease of operation and ability to adjust to field
conditions lighten your work and shorten your

You are urged to consult your International
Harvester dealer concerning unusual field

perience of your dealer and the organization
associated with him serve you.

justing and Operating in this manual. Check

your mower and inspect it. Preventive main¬
tenance pays dividends. Your dealer has orig¬

INTRODUCTION
The 3 spindle, center mounted. 38-. 42-,
and 48-inch rotary mowers, are designed for
use on International^ Cub Cadet<&Tractors
having serial number 65458 and higher.
The mower extends beyond the tractor
wheels to permit cutting close to shrubbery*
trees, fences, buildings, drive and walkway
edges, etc.
The mower is driven by a V-belt from the
engine mounted power take-off clutch. The
clutch is engaged and disengaged by means of
a hand lever mounted on the steering wheel
standard.
A heavy-duty V-belt connects the three
spindles and permits independent turning of
the blades when an obstruction is struck by a
blade. A spring-loaded belt tightener main<-
tains proper belt tension.
The 48-inch mower has a spindle drive sys¬
tem wherein each spindle; from left to right,
is driven progressively faster to aid in cutting
and discharging the cut material.
The blade spindle bearings are automotive
type tapered roller bearings that can be re¬
lubricated and are carefully enclosed and pro¬
tected by seals.
The three cutting blades are designed to
create a suction to lift the grass and hold it
for an even cut.
Raising and lowering of the mower is done
by means of the tractor lift handle or the
power lift attachment.
The lift linkage provides and maintains a
true parallel lift for the mower throughout the
cutting height range of 1 to 4 inches.
The lift linkage with mounting brackets can
be quickly detached by removing the quick-
attachable cotter pins and releasing the tractor
quick hitch.
The tapered discharge chute terminates at
a large, protected opening for efficient air and
material flow across the front of the mower
to minimize clogging.
