INTRODUCTION

The International 105 Balanced Mower

is designed for use on the International Cub 8
Lo-Boye, Farmall Cub e, International and

Farmal18 Super A, Super A-l, 100, 130 and

140 Tractors. It is well suited for both in­dustrial and farm use. A completing package

is required to mount on your tractor.

This mower is especially built for high­speed mowing. It is ruggedly built with an
exclusive new wrist-action drive, balanced
for smooth running for longer machine life
and operator's comfort. It is especially
designed for cutting heavy hay and othervegetation.

or for mowing highway shoulders,

rights-of-way, and other industrial applica­tions. It will operate efficiently with the cut­ter bar at any angle from. 450 below horizontal
to 900 vertical. This feature makes it desir­able for cutting steep highway banks and
slopes. The. free floating action of the cutter
bar permits close operating positions along
the contour of the ground.

The tractors must be equipped with one of

the following units:

LUBRICA TION

Lubrication Guide

This machine is designed to require a
minimum amount of lubrication; however, reg­ular and sufficient lubrication increases the

life of the machine, saves many dollars in

service parts, and is the best insurance

against delays.

Before starting, lubricate the complete
machine following the "Lubrication Guide",
and thereafter lubricate at regular intervals

as specified.

Care must be taken to see that all bearings
are lubricated their full length. To be certain

that all bearings are properly lubricated, the
lubricant should be forced into them until it
begins to appear at the sides.

Keep the lubricator gun clean and wipe off

all dirt from the lubrication fittings before
using the gun.

Key to Lubrication Guide

The symbols shown around the reference numbers in Illusts. 2A, 2B,

and 2C indicate the intervals of lubrication. Paragraph numbers

correspond to reference numbers in the illustrations.

More Often Than Daily

Twice daily, use chassis lubricant (pressure-gun grease)
and apply sufficient lubricant to flush out the old grease and
dirt.

Use chassis lubricant (pressure-gun grease).

Only a few strokes of the pressure-gun are required. Do
not use a high-pressure gun. Excessive lubricant forced
through the bearings may destroy the seals.

Use a pressure-gun lubricant (Lithium mUlti-purpose

grease, type 2). Apply 3/8-ounce of Lithium mUlti-purpose
grease, type 2. This can be determined in terms of strokes
of the lubricating gun, depending on the type used. Do notuse

a high-pressure gun. Under extremely dusty conditions,lubricate

every 20 hours.

ADJUSTING AND OPERATING

OPERATING

Before going into the field, check to see
that your machine is properly set up, adjusted,
and lubricated as in'structed.

Farmall and Internatianal Super A, Super A.l, 100, 130, and

140 Tractor: To raise the cutter bar. move the

left Touch-Control lever forward; to lower the

cutter bar. move the lever to the rear. To
raise the mower frame. move the right Touch­Control lever forward; to lower the frame move

the lever to the rear.

Be sure all nuts are tight. They should be

tightened after a few hours of service. Spread
all cotters to keep them from falling out.

The wrist action drive is rugged and simple
designed to insure long life and trouble free
operation, however, its precision construction

requires a certain amount of break-in time.

Therefore, it is suggested that this mower be

run at. half (1/2) throttle under actual field

conditions for approximately the first 10 hours

This should be sufficient break-in time, after

which the mower can be operated at full speed.

During the break-in period the bearings will

run warmer than usual, but will not cause any
undue damage because of the unit being pre­packed with "Lithium multi-purpose grease'!
as specified in the lubrication chart.

TOUCH.CONTROL SYSTEM

The Touch-Control power system utilizes

the power of the tractor engine to raise and

lower the cutter bar. A light touch of your
finger on the control lever is sufficient.

Illust. 4A

The cutter bar can be operated at any angle

from 450 below level to 900 above level for
mowing of terraces. steep banks. and ditches
as shown in Illust. 4A.

The mower can be regulated and adjusted

without stopping work while the tractor is in

motion or while standing still. Power is pro­vided any time the engine is running. Disen­gaging the engine clutch does not affect the

operation of the hydraulic power system.

Farmall Cub and Internatianal Cub Lo.8oy Tractors: To

raise the cutter bar, move the Touch-Control

lever forward; to lower the cutter bar, move

the Touch-Control lever to the rear. The

cutter bar and mower frame will raise and

lower together. Independent movement of the

cutter bar can be accomplished with the use of
the curb lift attachment.

CUTTING A SQUARE CORNER

To cut a square corner, turn the tractor

sharply to the right when the cutter bar ap­proaches the edge of the uncut material. A
little experience soon shows at just what point
the turn must be started.

CUTTER BAR LIFT

The cutter bar lift cable and lifting chain

should be set so that when the Touch-Control

lever is in the forward position, the cutter bar

will be approximately vertical. If the bar is

not vertical, this can be corrected by adjusting

the length of the cable and chain, either

lengthening or shortening.

Illust. 58

DRIVING MECHANISM

To adjust the drive belt, loosen the two

bolts 'IE" (1IIust.58) securing the belt shield to

the coupling frame. Turn the set screw "M",

onthe front side of this shield, until proper

belt tension is obtained. Retighten bolts. The
V -belt is properly adjusted when a slight thumb

pressure will deflect the belt 1 (2" a.t a point

midway between the pulleys.

CUTTER BAR TILT

Illust. SA

Power is delivered to the cutter. bar by
means of a roller chain drive, a universal
knuckle drive, and a heavy-duty V-belt. The
univ~rsal knuckle drive does not require
attention other than periodic lubrication.

To adjust the drive chain,loosen the bolts
holding the bearing housing to the rear mount­ing plate. Draw the sprocket against the
chain until proper tension is obtained. Hold­ing this pos ition, retighten the bolts.

Illust. SC

The cutter bar can be tilted upward or

downward either 40 or 80 from the horizontal

position by removing the tilt bolt "H" (1IIust.5C)

and moving it to the hole giving the desired

adju stme nt.

CAUTION! Be sure the shield over the chain

guard is in place to guard against injury.

INNER SHOE BALANCE SPRING

Illust.6A

The pressure of the balance spring is pro-

perly adjusted when 80 to 100 Ibs. is required

to lift the inner shoe.

To adjust the pressure of the balance spring,

loosen the two nuts on the spring adjusting bolt,

turning them clockwise. To apply additional

spring pressure, screw the spring adjusting

bolt into the spring plug, turning the bolt clock­wise. To reduce the spring pressure, screw
the adjusting bolt counterclockwise. Tightenthe

hex-nuts against the spring plug.

Illust.6C

The cur b lift attachment will hold the
mower above ground level. up to 10" high, in­dependent of the regular lift. This will enable

the mower to be used for high level cutting
with the cutter bar in the desired cutting angle.

HEIGHT OF CUT

To operate, move the Touch-Control lever

to raise the mower to the proper height
desired. Move the curb lift handle to set the

pin in the hole of the quadrant which will keep

the hold-up chain taut. It may be necessary
to readjust the length of the hold-up chain.

The mower will now be held at this height by

the hold-up chain. Using the Touch-Control

lever, lower the cutter bar until it is in the

desired cutting angle.
