STAY CLEAR OF THE PTO 

The PTO shaft safety guard (A) should be installed when 
the PTO system is not in use. 

 

 

 

Make sure that the tractor PTO speed matches the 
implement’s required PTO speed. 
 
Do not drive or operate the implement beyond the 
tractor’s PTO speed. 

 

 

Stop the engine and be sure the PTO has stopped 
moving before: 
(1) Connecting or disconnecting the PTO shaft. 
(2) Making any adjustment to the PTO drive or 3-point 

hitch. 

(3) Adjusting, cleaning or servicing PTO driven 

implements.

TRANSPORTING 

 
Raise all implements and place them in the locked-for-
transport position. 
 
Do not drive the tractor on the road with implements in 
motion. 

 

 

 

Couple the brake pedals together for travel at road 
speeds. (This only applies to models with two brake 
pedals.) 
 
Do not make sharp turns at road speeds. 
 
Always dim your headlights when another vehicle is 
coming toward you. Keep the lights adjusted so that they 
will not blind the driver of another vehicle. 

 

 

Before going down a steep hill, shift to the lowest speed 
in order to control tractor with the least braking possible. 
Do not coast downhill. 
 
Do not stop or start suddenly when going uphill or 
downhill. 

 

 

When loading (or unloading) the tractor onto a vehicle, 
use care as follows: 
(1) Use a strong loading ramp or loading dock. 
(2) Use the lowest reverse speed and drive up the 

loading ramp backward. 

(3) Set the parking brake and place wheel blocks firmly 

under the vehicle’s wheels. 

(4) Do not try to drive onto a trailer from the bank of a 

ditch. 

 

 

Secure the tractor and any other load with chains. Be 
sure they are tight. 
 
If chains are not available, use rope, wire, blocks, or a 
winch cable. Check the load after traveling a few 
kilometers, and every 100 km thereafter, to make sure 
that the ties are not coming loose. Also, check after 
rough bumps in the road.

TOWING 

 
When towing a load  that weighs more than the tractor, 
the trailer should have its own brakes. When towing, 
drive slowly, avoid hills and apply the brakes gently. 

 

 

 

A safety chain will help control an implement being 
pulled if it accidentally separates from the drawbar while 
traveling. Using appropriate adapter parts, attach the 
chain to the tractor drawbar support or to some other 
specified anchor location. Leave only enough slack in 
the chain to permit turning. 

 

 

Do not tow the tractor faster than the tractor’s maximum 
travel speed in the highest gear, and never more than 25 
km/h (16 mph). 
 
Check local regulations concerning towing. Towing is 
illegal in some countries. 

 

AFTER THE DAY’S OPERATION 

PARK THE TRACTOR SAFELY 

Park tractor on a firm level surface. 
When parking the tractor, couple the brake pedals 
together and set the parking brake securely. When you 
must park on a slope, position the tractor at a right angle 
to the slope and set the parking brake securely. Then, 
block both the front and rear wheels. 

 

 

Take all possible precautions as follows when leaving 
tractor unattended: 
(1) Disengage the PTO and lower any implement to the 

ground. 

(2) Move all shift levers to neutral. 
(3) Couple the brake pedals together and set the parking 

brake lever. 

(4) Run the engine for 2 to 3 minutes at one-third throttle 

speed and no load in order to cool it. 

(5) Stop the engine and remove the key. 
(6) Cycle the hydraulic controls to eliminate any residual 

pressure.

MAINTENANCE AND SERVICE 

AVOID EXPLOSIONS OR FIRES 

Refuel the tractor when the engine is cool and in a well-
ventilated area, preferably outside. 
 
Never fill the fuel tank with the engine running. 

 

 

 

Be sure to use the correct type and grade of fuel. 
 
Keep all sparks, flames and smoking materials well 
away while handling fuel. 
 
Ground the fuel funnel or nozzle against the filler neck 
on the tractor to prevent sparks. 

 

 

Do not overfill the tank or spill the fuel. If fuel is spilled, 
wipe it up immediately. Install the fuel tank cap securely 
after refueling. 

 

 

Be sure there is plenty of ventilation before charging the 
battery. Gas produced while charging the battery is 
explosive. 
 
Keep all sparks, flames, and smoking materials well 
away from battery. Hydrogen gas at a concentration as 
low as 7 per cent can explode in the presence of a spark 
or open flame and spatter acid. 
Use a flashlight to check the battery electrolyte level. 
Never use an open flame or match to check. 

 

 

Keep the engine clean and free of grass, leaves, or 
excessive grease. 
 
Let the engine cool down before storing the tractor in an 
enclosure or covering it with a sheet.
