Any tirne the tractor is washed or "hosed o{", - it
should be greased to force any moisture out of the

If ihe tractor is operated with the tractor wheels in
water above the front rvheel bearings, the front rvheel
bearings should be repacked with r'vheel bea-ring grease'
Periodic light oiting of the pivot points of linkrigc aids
operation.
Air Cleaner
Clean or replace when necessary. A loss of porver
is an indication that air cleaner service is rcquircd.
Do not cletrn' the c.lcmcnt rvith compressed air or
u'ash the element.
The air cleaner element should be cleaned by gently
tappirig orr rr flnt surfacc.
Replace the t'lcment if it is bent, crushed or damtrged
in any way, or if the dirt cloes not readily fall off.
When reirrstalling, be sure the clement fits the
adapter piate and the rving nut is finger tight.
Tires
Proper tire pressure is 12-18 psi (.842-1.265 kglcm'z).
Check regularly and maintain at proper pressure.
Battery
Regularly check electrolyte level. Maintain at proper
levcl by adding distilled water.

PTO Clutch
It is necessary that the PTO lever have free travel.
If the free travel is too great, the clutch r'vill not disen-
gage and if the free travel is too little, the clutch rvill
activate too hard and operation will be afiected. With
the PTO lever engaged (IN position) there should be
1.375 to 1.5 inches (3.49cm --3.81 cm) of frcc travel be-
tween the lever and the back of the slot in the cover
plnte.
- lVhen the free travel reaches one (1) nrch (2,54cm),
adjust the clevis on the PTO rod until there is 1.375 to
1.5 inches (3.493 - 3.81cm) of free travel of the lever
again.
NOTE: When operating the tractor rvithout a porvered
atterchn-ient, engirgc the PTO to iucrease oil circulatiotr
rvithin the transmission.

OPERATION
This tractor is equipped with a spur gear transmis-
sion and all speeds are obtained by shifting sliding spur
gears. Therefore, it is necessary to stop the fractor before
attempting to shift gears. The Direction Control Lever
must be in Neutral and the tractor stopped before shifting
the Range Selector Lever, or the Gear Selector Lever.
BEFORE STARTING
1, Check gasoline level. Use any high quality, regular
grade gasoline, The fuel tank holds 5.3 U. S. gallons
(20 L.).
2. Check oil level. See "Maintenance" section.
3. Check to see that PTO is in OUT position. Direction
Control Lever is in Neutral (Vertical to ground) and
Gear Selector Lever is in Neutral.
CAUTION: Be sure Direction Control Lever is in Neutral.
STARTING:
1. If engine is cold, move choke lever from OFF to
ON position.
2. Move throttle control to approximately halfway be-
tween "IDLE" and "FAST" position.
3, Turn Ignition Key to start (clockwise). Do not hold
engaged more than 15 seconds without allowing a
30 second cooling period for sharter motor.
4. As soon as the engine starts, release the key.
5. After the engine starts, and as it warms up, move
choke control towards the OFF position.
STARTING TRACTOR MOVEMENT:
1. Move the Gear Selector Lever to desired gear.
2. Move Rang Selector Lever to desired range.
3. To go forward, push the Direction
forward (away from you) gradually
in place.
Control Lever
until it locks
4. To back up, pull the Direction Control Lever back
until it locks in place.
5. To stop tractor motion, apply brake.
NOTE: The transmission linkage is equipped with a
cam so that when the brake is applied, the Direction
Control Lever automatically moves to neutral.
DO NOT SLIP FORWARD.REVERSE CLUTCHES
TO ACHIEVE SLOWER GROUND SPEEDS. DOWN
SHIFT OR TAKE SMALLER SWATH IF GROTIND
SPEED IS TOO FAST FOR THE ATTACHMENT TO
DO ADEQUATE, JOB.
STOPPING TRACTOR:
1- Apply brake.
2. Be sure PTO Lever is in OUT position,
3. Move throttle to idle.
4, Turn ignition key counter-clockwise to shut ofi en-
gine, Removed key. Tractor cannot be started with-
out the key.
Engaging Power Take Off (P.T.O,):
1. Stop tractor motion, slow engine to fast idle. (This
will reduce PTO clutch wear and prolong PTO
clutch life).
2. MOVE PTO Lever from OUT to IN.
Disengaging Power Take OFF (P,T.O.):
1. Move PTO Lever from IN to OUT.
CAUTION: Stop tractor and disengage PTO and turn
ofi ignition key before attempting to work on or adjust
the attachment.
Air cooled engines are designed to be operated at full
throttle (3600 rpm). Operate the tractor wi,th the engine
at full throtfle, particularly when operating under loads.

REAR HITCFI
Figure 10, 816
816
This tractor is equipped with a liftable rear hitch for
mounting of powered and non-powered rear attachments.
It also can be secured in fixed position for use of the
tractor with center-mounted or front mounted attach-
ments. This allows the raising and lowering of the
attachments without affecting the position of the rear
hitch.
The locking strap is secured from the frame to the
rear hitch and the lift rod removed.
Figure 10 shows the hitch liftable. Figure 11 shows
the hitch rigid.
Most non-powered liftable rear attachments mount
with a pin. See ffgure 12.
Be sure to attach liftable rear altachments using the
pin provided with the tractor.
Trailing attachments, such as carts, can be secured to
.he hitch using the trailing hitch kit, See page 13.

This tractor is equipped with a rear hitch for mount-
ing trailing attachments using the trailing hitch kit. A
liftable rear hitch is an option
