1. SAFETY PRECAUTIONS
SA221/324/424 Operation Manual
1. Understand the performance and limitations of
the tractor. Carefully study the Operation Manual
and learn the instructions in the Operation
Manual before operating or servicing the tractor.
Keep the Operation Manual in an easily
accessible place.
2. Strictly follow the statements given in the safety
decals attached to the tractor.
3. Do not operate the tractor without the Roll-Over
Protective Structure (ROPS).
Keep the retractable seatbelt fastened while
operating the tractor with the Roll-Over Protective
Structure (ROPS). The preceding practice will
reduce the possibility of injury or death in the
event of roll over accident.
If the Roll-Over Protective Structure (ROPS) has
been removed for any reason, ensure to install all
the associated parts before operating the tractor.
Do not alter the Roll-Over Protective Structure
(ROPS). The altered Roll-Over Protective
Structure (ROPS) may fail to provide the
designed protection. Replace the damaged Roll-
Over Protective Structure (ROPS) immediately.
Contact YOUR LOCAL YANMAR TRACTOR
DEALER for technical assistance.
The Roll-Over Protective Structure (ROPS) may
be temporarily folded when absolutely necessary
for areas with height limitations. Do not wear the
retractable seatbelt when the Roll Over
Protective Structure (ROPS) is in the folded
position. For operator safety, always keep the
Roll-Over Protective Structure (ROPS) installed
in the tractor.
NEVER alter or repair the Roll-Over Protective
Structure (ROPS). Welding, bending, drilling,
grinding or cutting may weaken the Roll-Over
Protective Structure (ROPS). Contact YOUR
LOCAL YANMAR TRACTOR DEALER for
technical assistance. The seat is included in the
safety zone by ROPS. When replacing the seat,
use Yanmar genuine parts.
4. Use the retractable seatbelt while operating the
tractor with the Roll-Over Protective Structure
(ROPS) in the upright position in the tractor.
Check the retractable seatbelt for any damage.
Replace the damaged retractable seatbelt
immediately. Contact YOUR LOCAL YANMAR
TRACTOR DEALER for technical assistance. Do
not modify, disassemble or attempt to repair the
seat belt.
5. Check overhead clearance carefully before
driving under power lines, wires, bridges or low
hanging tree branches, before entering or leaving
buildings, or in any other situation where the
operator and/or Roll-Over Protective Structure
(ROPS) may be struck, which could result in
serious injury.
6. Make sure that the usual operator and any other
person who will operate the tractor studies the
Operation Manual before operation. Know the
controls and how to stop the tractor quickly.
7. Make sure that any person or obstacle is not
under or around the tractor before and during
operation. Make sure to maintain sufficient
overhead clearance above the tractor.
8. Do not operate the tractor and/or implement
installed on the tractor while under the influence
of alcohol, drugs, medicine or controlled
substance/s or when not fit to operate the tractor.
9. During operation and when performing service
work:
• Wear close-fitting clothing.
• Do not wear loose-fitting clothes, jewelry, baggy
or torn clothing.
• When any of the preceding items is caught by a
moving part of the tractor, an accident can
happen.
• Do not wear cut-off pants or shorts which do not
provide protection against flying debris.
• Do not under any circumstances operate the
tractor with bare feet.
• Do not wear sandals or sneakers.

1. SAFETY PRECAUTIONS
SA221/324/424 Operation Manual
• Wear additional protection including non-slip
safety boots or shoes, protective goggles and
gloves, etc., as appropriate or required by
applicable local laws and regulations.
• Wear ear protection in a noisy environment to
prevent hearing damage and to reduce operator
fatigue.
10. Avoid allowing passenger/s on any portion of the
tractor.
11. Always remain seated in the operator seat while
operating the tractor.
12. Make sure that the brakes and other mechanical
components are properly adjusted and do not
have excessive wear.
• Immediately replace all excessively worn out or
damaged components.
• At regular intervals, check that all nuts, bolts and
screws are properly tightened. (For details, see
"Chapter 13. MAINTENANCE" on page 13-1).
13. Always keep the tractor clean. Dust, grease or
grass clippings accumulated on the tractor can
lead to fire accidents or personal injury.
14. Use the handholds and running board step when
getting on and off the tractor to help prevent
accidental falls. Keep the running board step
clear of mud and debris.
15. Only use the implements that satisfy the
requirements in the Operation Manual or are
approved by your Yanmar tractor dealer. (For
details, see "Chapter 4. IMPLEMENT
CAPACITIES" on page 4-1).
16. When using front, mid- or rear mounted
implements, install an appropriate weight/s to the
front or rear of the tractor to prevent upsetting the
tractor. When using the mid-implement, the
operator may use front and rear weights. If the
operator choose to use the loader, mount an
implement or weight to the 3-point hitch in order
to stabilize the tractor. Observe the instructions
about safety in the Operation Manual for the
implement to be used.
17. Remember that a narrower tire tread width can
lead to greater possibility of upsetting the balance
of the tractor. To positively stabilize the tractor,
select a maximum possible tire tread width
appropriate for the intended application. Contact
YOUR LOCAL YANMAR TRACTOR DEALER for
technical assistance.
18. Do not under any circumstances modify the
tractor. Modification can deteriorate the
performance and/or safety of the tractor, possibly
leading to personal injury or property damage.
19. Do not attempt to adjust the low or high idle
speed limit screw. Adjusting the low or high idle
speed limit screw may impair the safety and
performance of the tractor and shorten the life of
the tractor.
1. Start the Tractor
1. Remain seated in the operator seat when starting
the engine or actuating the levers or controls. Do
not start the engine or operate controls while
standing beside the tractor.
2. Before starting the engine, ensure that all the
levers are in the N (neutral) positions, the parking
brake is engaged securely, and Power Take Off
(PTO) switch is in the OFF position.
3. Always keep the retractable seatbelt fastened
around the operator’s waist whenever the Roll-
Over Protective Structure (ROPS) is installed on
the tractor.
4. If the tractor is started where there is a height
limitation, immediately after exiting from low
height structure return the Roll Over Protective
Structure (ROPS) and fasten the retractable
seatbelt.
5. Start the engine of the tractor only by using the
starter key switch. Avoid starting the engine by
short circuiting across the starter solenoid
terminals with a jumper wire, or by bypassing the
safety start switch. This defeats the safety
interlock circuit and the tractor may begin to
move and/or the Power Take Off (PTO) shafts
may begin to rotate, possibly leading to personal
injury or property damage.
6. Avoid running or idling the engine in a confined
area that is poorly ventilated or not ventilated at
all. The engine emits carbon monoxide gas that is
colorless, odorless and can cause death.

SA221/324/424 Operation Manual
7. Before operation, check that all the safety
features are functioning correctly. Never tamper
with safety devices. Check the proper operation
regularly. Contact YOUR LOCAL YANMAR
TRACTOR DEALER for safety devices
malfunction.
8. Avoid accidental contact with control pedals while
the engine is running, as this can cause
unexpected movement of the tractor.
9. Always attend to the running tractor.
2. Work with the Tractor
1. Make sure that all the covers and guards are in
position. Replace any missing or damaged
covers immediately.
2. Before turning or during traveling on a rough
terrain, or before stopping, decrease the tractor
speed in order to prevent upsetting.
3. Use extra caution during operating over rough
ground, when crossing ditches or operating on
slopes and when turning corners.
4. Stay clear of ditches, potholes, embankments or
ponds. The incident of upsetting the tractor can
occur more on soft or wet ground. Before
entering an area covered with tall grass, inspect
the area to detect any obstacles.
5. The operator should always pay attention for
blind corners, trees and other object that can
obstruct the operator's vision. The operator
should always remain alert when approaching the
row of trees or any obstacle.
6. When two or more people are working in one
area, always keep in good communication
between each other.
7. Do not under any circumstances get on or off the
moving tractor.
8. When driving at night, ensure that all necessary
lights are illuminated.
9. When driving, do not shift the range gear. Always
shift the range gear when the tractor is
completely stopped.
3. Stop the Tractor
The procedures of stopping the tractor are as
follows:
1. Reduce the engine speed.
2. Release the forward and reverse drive pedal
completely.
3. Depress the brake pedal to stop the tractor.
4. Considerations for Safety of a Child
Tragic accidents can occur if the operator is not alert
to the presence of a child. A child is often attracted to
the tractor. A child does not understand the dangers.
Never assume a child will remain where the operator
last saw the child.
1. Keep a child out of the operating area and under
the watchful care of an adult other than the
operator.
2. Be alert if a child enters the work area, stop the
tractor immediately.
3. Never allow a child to ride on the tractor. The
child can fall off and be seriously injured or
interfere with safe tractor operation.
4. Never allow a child under 16 years old to operate
the tractor. A child, 16 years old and under should
only operate the tractor under close parental
supervision and proper instruction.
5. Be extremely careful when backing the tractor.
Before and during backing, look back and
downward. A child may be in the path.
6. Use extra care when approaching blind corners,
shrubs, trees or other objects that may obscure
the operator’s vision of a child or other hazard.
7. Never allow a child to play on the tractor or
implement.
8. Keep a child away from hot or running engine.
The child may suffer burns.

1. SAFETY PRECAUTIONS
SA221/324/424 Operation Manual
On a slope, the tractor is less stable and more prone
to tip over, possibly leading to serious injury or death.
Remain very cautious while the tractor is on any
slope.
DO:
●Operate up and down slopes, not across.
●Remove obstacles such as rocks, limbs, etc.
●Watch for potholes, ruts or bumps. Uneven terrain
can overturn the tractor. Tall grass can hide such
obstacles.
●Place the transmission in the low range when
climbing or descending slopes. Always keep the
tractor in gear when going down slopes to take
advantage of engine braking action.
●Keep all movement on the slopes slow and
gradual. Do not make sudden changes in speed or
direction. Rapid engagement or braking can cause
the front of the tractor to lift and rapidly tip over
backwards which can cause serious injury.
●Avoid starting or stopping on a slope. If tires lose
traction, push down Power Take Off (PTO) switch
to OFF position and proceed slowly straight down
the slope.
●To avoid tipping or turn over, move backward up a
steep slope. If backing on the slope is difficult, do
not attempt to continue. Avoid an extremely steep
slope.
●When moving forward to get out from a ditch, deep
mud or when traveling on a steep slope, the risk of
the tractor tipping or turn over backward is high.
Always move backward to get out from these
situations. In the 4-wheel drive mode, special
caution is needed to avoid potential tipover when
traveling up and down slope site conditions.
●To improve stability on a slope, select the widest
possible tire tread width. Observe the instructions
for appropriate weighting.
●Do not operate on wet grass. Tires may lose
traction on slopes even though the brakes are
functioning properly.
●Keep away from drop-offs, ditches or
embankments during mowing. The mower could
suddenly turn over if a wheel goes over the edge of
a cliff, ditch or if an edge caves in.
5. Operate the Tractor on Slopes
●Keep away from slopes steeper than 15
degrees. See page 8-17 "Operate on Slopes
and Rough Terrain" for the details.
●Before approaching a slope, select an
appropriate speed setting. Make sure to run
the tractor at a lower speed on slopes. Never
attempt to shift gears on a slope. The tractor
can suddenly go downhill out of control.
Avoid increasing and decreasing the tractor
speed rapidly.
●Do not move the range shift lever in the N
(neutral) position when on a slope.
●When climbing or descending a slope, do not
shift the range shift lever. Shifting the range
shift lever into the N (neutral) position can
result in loss of control of the tractor.
●Starting the tractor with the front end uphill
can cause the front wheels to jump off the
ground and this situation poses an extreme
danger. To avoid this problem, run the engine
at a lower speed, and gently start the tractor.
●Avoid parking the tractor on a slope. If parking
on a slope is unavoidable, chock all the tires
safely and securely and engage the parking
brake securely, for details, see "6. Lock and
Set the Parking Brake" on page 7-3.

2. Before accessing the engine, muffler, radiator
and radiator cap or other possibly hot
components, wait until the tractor has fully cooled
down.
3. Keep the tractor and the attachments free of
grass, leaves or other debris build-up.
4. Use extreme care in handling diesel fuels. Diesel
fuels are extremely flammable and the vapors are
explosive. Use only a container approved by the
local effective law.
5. Close fuel shut-off valve before servicing the fuel
system.
6. Make sure to shut off and cool the engine before
refueling. After refueling, replace fuel filler cap
securely and wipe off any spilled diesel fuel
before starting the engine as the diesel fuel may
cause a fire or explosion.
7. Do not smoke while refueling. Keep any spark or
open flame away from the fuel tank.
8. Never refuel the tractor indoors because diesel
fuel vapors will accumulate in the area.
9. Never store the fuel container or tractor indoor
where there is an open flame or spark, such as a
gas water heater, space heater or furnace.
10. Do not smoke while working around the battery.
Keep any sparks or open flame away from the
battery. The battery emits hydrogen and oxygen
gasses, in particular during recharging and can
pose a hazard of explosion.
11. Prior to “jump starting” a tractor that has fully
depleted battery, read and follow all the
instructions in “Chapter 15. SERVICE THE
ELECTRICAL SYSTEM” on page 15-1.
12. Add coolant or water to the reserve tank, not to
the radiator (For details, see “Check the Cooling

loosened.
18. Keep the tractor securely supported while
changing the wheels or adjusting the tire tread
width. Make sure to tighten the wheel bolts to the
specified tightening torque.
19. Avoid working under any hydraulically supported
devices. Such devices can leak, suddenly settle
down, or be accidentally lowered. If working
beneath the tractor or an implement is
unavoidable, ensure to use a stand or lift
apparatus with the capacity of more than 3 tons.
20. High pressure hydraulic fluid when released can
penetrate human skin, possibly leading to serious
personal injury. Before disconnecting any
hydraulic line, fully release the internal pressure.
Before exerting a pressure to the hydraulic
system, ensure that all connections are tight and
all the lines, pipes and hoses are free from
fractures/fissures or any other damage.
21. Search for leaks with a piece of cardboard.
Protect hands and body from high pressure
fluids.
22. If an accident occurs, see a doctor immediately.
Any fluid injected into the skin must be surgically
removed within a few hours or gangrene may
result.
23. Check brake operation frequently. Adjust and
service as required.
24. Keep all bolts and nuts tightened, make sure the
tractor and the attachment is in safe working
condition.
25. Avoid changing the engine governor settings or
overspeed the engine. Excessive engine speeds
are dangerous.
26. Observe proper waste disposal laws and
regulations. Prior to disposal, determine the
proper method to dispose of waste from your
local Environmental Protection Agency.
Recycling centers are established to properly
dispose of materials in an environmentally safe
fashion.
27. Use container approved by the effective law
when draining fluids. Avoid using food or
beverage containers that can mislead someone
into drinking from food or beverage containers.
Properly dispose of the containers immediately
following the draining of fluids.
28. Observe your local Environmental Protection
Agency regulations when disposing of oil, fuel,
coolant, brake fluids, filters, batteries, tires and
other harmful waste.
29. Yanmar does not recommend the use of a
pressure washer or garden hose to clean the
tractor. Electrical components, spindles, pulleys,
bearings or the engine can be damaged. The use
of water will result in shortened life and reduce
