FOREWORD
Your t ractor has become your partner and will amply return the investment you have
placed in it. Years of thought and experience and close contact
with farmers have re-
sulted in
the many refinements and features built into the tractor. It has been carefully
manufactured under close supervision
and careful inspection and if it is given the care
and service outlined in
this manual, years of trouble-free operation will result.
BEFORE OPERATING YOUR NEW TRACTOR
STUDY
THIS MANUAL CAREFULLY
If you feel that you requir einformation not contained in this manual consult your deal-
er who has
the trained personnel and the required equipment to give you the service you
require. All dealers
are kept informed on the best methods of handling your tractor prob-
lems and
their mechanics have the training and experience on your tractor to give your
problems personal attention
and quick satisfaction.
Dealers
carr yample stocks of genuine parts and in turn are backed by the full facilities
of
th eCompany with Branches and Distributors conveniently located. When parts are re-
quired be
sure to give the dealer your engine and tractor serial numbers. It is suggested
that you write these in the space provided below.

(Prepared by the Farm Safety Committee of the Farm Equipment Institute and approv-
ed by the National
Safety Council, Incorporated.)
1. Be sure the gear shift lever is in neutral before starting the engine.
2. Always engage
the clutch gently, especially when going up a hill or pulling out of a
ditch.
3. When
driving on highways, or to and from fields, be sure that both wheels are braked
simultaneously when making an emergency stop.
4. Always ride on
seat or stand on platform of tractor. Never ride on drawbar of tractor
or drawn implement.
5. When
tractor is hitched to a stump or heavy load, always hitch to drawbar and
never take up the slack of chain with a jerk.
6. Be extra careful when working on hillsides. Watch out for holes or ditches into which
a wheel
may drop and cause tractor to overturn.
7. Always keep tractor in gear when going down steep hills or grades.
8. Always drive
tractor at speeds slow enough to insure safety, especially over rough
ground or near ditches.
9. Reduce speed before
making a turn or applying brakes. The hazard of overturning
the tractor increases four times when speed is doubled.
10. Always stop power take-off before
dismounting from tractor.
11. Never dismount from tractor when it is in motion. Wait until it stops.
12. Never
permit persons other than the dri vel' to ride on tractor when it is in opera-
tion. . .
13. Never
stand between tractor and drawn implement when hitching. Use an iron hook
to handle
drawbar.
14. Do not put on or remove belt from belt pulley while the pulley is in motion.
15. Should
motor overheat, be careful when refilling radiator.
16. Never refuel tractor while motor is running or extremely hot.
17. When
tractor is attached to a power implement be sure that all power line shielding
is in place.

CARE AND OPERATIO N
Before starting a new tractor - READ YOUR INSTRUCTION BOOK
1. Lubricate the entire tractor, ref erring to the "Lubrication' Chart" on pages 10 and 11
and check oil levels as specified on page 9. ' .
2. Check
tire inflation ref erring to instructions on tires, page 30.
3. Check cooling system
ref erring to instruct ions on pag es 13 and 19.
4. Use correct oil - ADD
ONE PINT OF ENGINE OIL FOR EVERY FIVE GAL-
LONS OF
FUEL DURING THE FIRST 100 HOURS.
5.
For a new engine, use SAE 20 above 320F., for the first season of operation.
6. CAUTION -
For the first 40 hours, work tractor to about one half .capacity. Use only
first and second gear to avoid overloading the engine.
7. Long life is
built in the modern engine and it can'best g-i ve you the service you desire
by
reading and following th einstruction as outlined in this book.
8. Always allow an eng-ine which
has been under load to idle for a few minutes before
stopping, as
this allows the circulating water to cool the cylinders, valves, etc.
Watch
the oil level carefully, and change as recommended on page 12.
9.
Ser vice the oil filter and the air cleaner as instructed on pages 17 and 18.
10.
For maximum economy use the highest transmission rspeed, and the lowest engine
speed, which will
maintain the desired speed of travel, without overload ing excess-
ively.
CLUTCH
The engine drive is
taken through a spring loaded dry disc single plate clutch and
is designed so
that it requires a minimum of attention.
CARE AND
ADJUSTMENT OF CLUTCH
It is ve ry important that free clutch pedal trav el .be maintained at from 1" to
1 %". After a new tractor has run for a short while this tra vel should be checked
and
adjustment can easily be made by means of the clevis at the front end of the
clutch rod. During- normal tractor service the driv er must watch to see that the
free travel be maintained as if it is less than this the clutch is apt to slip and be
badly damaged,
and if more than l1; ~" the clutch may not release completely when
depressed,
making shifting difficult. .
During the operation the driver should refrain from keeping his.foot on the clutch
pedal to
prevent slipping while in use.

EN GINE LUBRICATION
ENGINE OILING SYS TEM - Functioning as it does to pro vide lubrication for all the
moving parts of the engine which operates under different conditions of. h eat and
pressur e, it is necessary that a good grade of engine oil.be used. It is also impor-
tant that the oil be kept CLEAN and in a CLOSED CLEAN CONTAINER "
. . • . i
DESCRIPTION - Pr essure is furnished by a gear type pump which dra ws the oil from
the crankcase through ascreen. From the pump it goes through passages drilled in
the block to the main and connecting rod bearings. The connecting rods are rifle
drilled
for satisfactory wrist pin lubrication. Oil is meter ed to the rocker arm shaft
for satisfa ctor yrocker arm lubrication and to th e rock er arm valve contact faces.
The camshaft is oiled by splash and by oil draining from th e head through cored
passages in
the block. The governor, governor shaft , and timiri gg ear s ar eliber-
ally bathed in oil to
prevent undue w ear and to wash off accumulated sludge and
moisture.
Part of the oil is by-passed through the filter. (See pag e 17 for servic-
ing.
PRESSURE CONTROL - A pr essur e reli ef valve is located at the front of the oil
gall
ery on the left side of the block and should not requir e att ention. It is danger-
ous to
tighten up a pressure valve to correct a drop in pr e ssur e, as normally such a
drop is caused by some ' bearing being worn. The oil pr essure as i ndicat ed on·t he
gaug eshould be from 20 to 25 pounds at full throttl e and 8 to 10 pounds at idle
speed. ; '
TYPE OF OIL - Above 320F., SAE 30 should be used, from -100F. to 320F. use SAE
20W, and below 100F., use SAE lOW. Always use top quality oil..
CAUTION: For anew engine use SAE 20 above 320F. for the first season of operation.
WHEN TO CHANGE AND ADD OIL - It is a good practi ce to change th e oil eve ry 60
hours and if running in cold w eather the change should he made more oft en. The
oil capacity is 4% Imperial quarts. Always look at the oil pr essur e gau ge immed-
iat elv after starting the engine. The oil level should be checked at lea st once a day
and if at, or below, the low mark on the dipstick, some should be added.
QUALITY
OF OIL - The best insuranc e of good qualitv is to buy from a r eput able
manufactur er. Oils should be fr ee from foreign substances such as scans. resins,
acids, etc.,
and should not corrode the engine surfaces. The newer, so-called heavv-
dut y oils are satisfactory hut if an engine has heen run on oth er tvp es of oils do
not add heavy-duty oil without thoroughlv flushing ' the crankcase by ari ap pr oved
motor flush svstem. Even after this is done. t.he new heavy-duty oil should be
changed
at 10 hour s, then at 25, and then at 60.
https://tractormanualz.com/

CHASSIS LUBRICATION
FRONT W HE EL BEARINGS - To provide satisfactory lubrication to the front wheel
bearings remove wheels, clean
and repack with wheel bearing grease periodically.
QUALITY OF LUBRICANT - Use a good
grade of mineral oil made by a reputable
manufacturer as
the best assurance of trouble-free service. SAE 90 transmission
lubricant can be used both winter and summer.
13Oper ati ng Instructions for Cockshutt "30" Tractor
BRE ATHER CAP - This cap acts as a filter to clean the air which surges into and out
of an engine when it is operating. To remove dust and dirt from the air drawn in
on
the inward surge, the screen must be kept clean and covered with oil. It should
be inspected
and if dirt is present, the cap should be washed in gasoline, then dip-
ped in engine oil, excess oil
shaken off, and the cap put in place again .
PRESSURE GUN LUBRICATION - Use a good quality grease, not one that will thin
o ut under load and moderate temperatures. Keep the grease and the gun clean -
clean each fitting before use and force enough lubricant into fitting to insure a
fr esh supply to the wearing surfaces.
At least once a year, or every 1000 hours, drain transmission compartments by removing
the
three plugs, 21 and 22, on the lubrication chart. Preferably the draining should be
done while
the tractor is warm.
The t ra nsmission will require 4%, Imperial gallons (5 U.S. gallons) to fill and the pulley
hous
ing I%, Imperial gallons (2 U.S. gallons). After filling the transmission do not use
the cree
per with the shift in the low speed (lever towards the rear) until the tractor has
been o perated for about one hour or so, asthis chamber is filled from the transmission by
splash.
If the tr ac tor is operated at very low temperature the pulley housing and transmission
lubrica
nt may be thinned with one half gallon of kerosene, but before using in warm wea-
th er this thinned mixture MUST be drained and replaced by new oil.

ENGINE
CONSTRUCTION - The engine is a heavy duty, 4 cylinder, valve in head, wet sleeve
motor with apressure oiling
syst em as described in detail on page 12.
A water pump is used with a full flow by-pass thermostat to insure consta nt
motor temperature which is so imp ortant in securing long life from the wear ing
parts . All working parts are protected by the larg ecapacity oil filt er used, the
heavy duty air cleaner, and the careful sealing of the main bearings at the front
and
rear of the crankshaft .
The
high quality variable speed governor provides constant engine speed control.
The main connecting rod bearings
are of high precision, interchangeable, steel-
backed
babbit design.
SERVICE -
It is strongly recommended that, should any work have to be done on the
motor, it be taken to your dealer. You I' deal er has the proper facilities and the
trained personnel to give your tractor th e efficient attention that it deserves.

VALVE TAPPET AD JUS TMENT
PLATE No. C-21-t6
Every 400 hours or once a year, it is recommended
that a compet ent mechanic check the tappet clear-
ance. A clearance of .009" is necessary between end
of rock
er arm s and valve stems when valves are
closed and the engine is warm.
(1) Before checking valve clearance, make sure
ignition switch is off. This elimina
tes d ang er
of accidently starting the engine.
(2) Remove valve cover. ••
(3) Crank the engine slowly, watching No.4 cylinder valves. When the exha ust valve is
just closed and the intake valve is just starting to open, No .1 cyli nder is at top dead
centre on the compression stroke -
and both valves are closed.
(4) Loosen the lock n
ut as indicated by arrow (1) and adjust screw as indicated by
arrow (2) in rocker arm so that a .009" feel er gauge as indicated by arrow (3) slips
snugly between end of rocker
arm and the valve st em.
(5) Tighten lock
nut and recheck clearance. Check both intake and exhaust valves on cyl-
inder. ,
(6) Crank engine 1f2 revolution at a tim e and check clearance of each cylind er's valves
and
adjust as instructed above. Do this on each set of cylinder valves in succession
according to
the firing order of the engin e, which is 1, 3, 4, 2, as shown on Plate No.
C-20-46 on page 26.
(7) Replace valve cover. Check to make
sure the valve cov er gasket makes an oil-tight seal
with
the cylinder head. Replace the gasket, if necessary, with a new one.

ating conditions and while a

operating with too lean a mixture
as power is lost and the engine will

OIL FILTER
PL ATE No. C·1 3-46
Clean oil in an .engine insures that the bea rings will be properly lubricated th us keeping
them cool and giving them a long life.However, all engines
form sludge while in opera-
tion and minute particles of
dirt also accum ulate in the crankcase; as a result, acids,
gums, varnish, and
other by.products are pres ent .
To remove these harmful substances a high capacity filter is used which under normal
conditions will remove the
dirt, etc., for aro und 120 hours of operation; aft er this time
the
dirt , etc., starts to plug t hecartridg e and soon it will be inoperative.
Every 100 hours,
as outlined above, change the elem ent as follows:
(1) STOP ENGINE -
(2) Drain filter by removing drain plug at bottom of oil filter as indicated by arrow (1) .
(3) Remove oil filter cap as indicated by arrow (2) .
(4) Remove
air cleaner cup as indicated by arrow ( 3).
(5) Wipe dirt off of oil filter cap, unscrew clamping tee screw and remove filter top as
indicated by
arrow (4).
(6) Remove and discard old elem ent as indi cated by arrow (5) ; use a clean rag and wipe
out any sludge remaining in.bottom of shell as indicated by arrow number (6); in-
spect new element and replace as
indicat ed by arrow number (5) .
(7)
Start engine and check filter for oil leaks, letting th eengine run for a few minut es
to allow
filt er to fill with oil.
(8) Check oil level and add sufficient to rep lace the amount which was fed into filt er.
(9) IMPORTANT - Do
not use cheap or su bstitute oil filter elements as th ey may be
inf erior in quality, and poorly packed and co ntain foreign substances. Always carry
extra elements on hand.

AIR CLEANER
PLATE No. C· 14-4 6
•
CAUTION - Do not remove the oil cup while
engine is operating. Refill the oil cup to
oil level bead with the same grade of oil
used in
the engine crankcase. The capa-
city of the oil cup is 1%Imperial pints.
OIL
CUP SERVICE - Remove, clean, and re-
fill
the oil cup every day, as indicated by
arrow (l), or after every 10 hours of
operation (more frequently when oper-
ating under dusty conditions).
AIR
INT AKE CAP AND SCREEN - This
screen, as indicated by
arrow (2), should
be kept clean and free from all chaff, oil,
dust or paint, as clogged holes in the
screen will reduce
the power of the en-
gine by
restricting the flow of air.
Clean
air for combustion is assured by a three-
.stage oil-type air cleaner. A heavy screen in
the
air intake cap prevents large particles
from
entering the air cleaner. The air then
passes to
the oil cup where it goes through a
bath of oil. As the air rises to the outlet to the
intake manifold it passes through aseries of
oil-bathed screens
and the fine dust is remov-
ed. As the oil from the screens works back
down, it
carries the dirt with it and the dirt
settles in the oil cup. The oil cup must be
cleaned
and refilled regularly with new oil.
