Yanmar diesel tractor EF494T. OPERATOR'S MANUAL - part 2

 

 

EF494T OM 

STARTING 

START THE ENGINE SAFELY 

If you operate the engine inside a closed building, be 
sure there is plenty of ventilation before starting the 
engine. Exhaust fumes are poisonous. Carbon 
monoxide is especially dangerous because it is odorless 
and colorless. You can easily be overcome without 
realizing it. 
Always stay near the tractor and keep the parking brake 
set securely while warming it up. 

 

 

 

Only start the engine from the operator’s seat. Never 
start the engine while standing on the ground. 
 
 

 

 

Before you start the engine: 
(1) Sit in the operator’s seat and adjust the seat position 

if necessary. 

(2) Make sure the ROPS is in working condition and 

seat belt securely fastened. 

(3) Lower any implement to the ground. 
(4) Place speed shift lever and the PTO switch in 

neutral. 

(5) Set the parking brake. 
(6) Disengage the PTO for the neutral position. 
(7) Check all the instruments, gauges and indicator 

lights. 

(8) Be sure everyone is clear of the tractor and 

implement.

DURING OPERATION 

OPERATE THE TRACTOR SAFELY 

Keep people and pets a safe distance away when 
starting and operating the tractor and implement.  
 
Do not permit any person other than the operator to ride 
or board the tractor or implements, including any 
wagons. 
 
Do not play games with the tractor. 
Never allow children to ride on your lap. 
 

 

 

 

Do not touch the muffler, radiator, engine or other high 
temperature parts before they have cooled down 
completely. 

 

 

Do not try to get on or off a moving tractor or 
implements. Always use the handrails and steps and 
face the tractor when getting on and off. 
Never use control levers as a handhold and never step 
on foot controls when getting on and off. 
Do not get on the tractor with wet or greasy hands, or 
muddy shoes. Do not jump off the tractor. Be aware of 
slippery conditions on the ground. 

 

 

Make sure you check the connecting points on your 
equipment. 
 
Keep hands, feet and clothing away from power-driven 
parts. Keep others away from articulated joints, hitches, 
drawbar, lift arms, PTO drives, cylinders, and anything 
else that moves. 
 
Never stand, or allow anyone else to stand, between the 
tractor and an implement, unless the engine is turned off 
and the parking brake is engaged securely.

OPERATE THE TRACTOR SAFELY (continued) 

Oversized implements are dangerous for tractor 
operation and are not safe for you. Refer to the 
implement’s operator manual for the minimum and 
maximum horsepower requirements and weights that 
are allowed. 
When using a heavy implement in front, always install 
ballast or an implement on the rear for safe, stable 
steering control. 

 

 

 

When using a heavy implement on a rear 3-point hitch, 
always install ballast or an implement on the front for 
safe, stable steering control. 

 

 

Slow the tractor down when crossing rough ground, tall 
grass or weeds. Rocks, holes and stumps may be 
hidden in the brush. 
 
Do not let your tractor bounce. You may lose steering 
control. 
 
Never use the tractor to round up farm animals. 

 

 

Do not allow the tractor to coast downhill with the clutch 
in, or with the gear shift in neutral. 

 

 

When operating the tractor on a slope, set the wheel 
tread as wide as possible for maximum stability, reduce 
the engine speed and avoid quick application of the 
brakes or sharp turns. 
 
Stay off hills and slopes which are too steep. 

 

 

 

EF494T OM 

AVOID TIPPING OVER 

When starting the tractor on an uphill slope, shift to as 
low a gear as possible and reduce the engine speed to 
avoid tipping over backward. 

 

 

 

Do not drive near the edge of a gully or a steep 
embankment. Avoid holes, ditches, etc. which may 
cause the tractor to tip over, especially on hillsides or 
steep slopes. 

 

 

When operating on slopes or rough uneven ground, it is 
important to have as much distance as possible 
between the wheels. Operate the tractor carefully at the 
lowest speed. 
 
Do not pull carts etc. from the top link or the top link 
hinge, rear axle, or any point above the drawbar. Doing 
so could cause the tractor to tip over backward. Only 
attach items to be pulled to the drawbar. 
 

 

 

Use care when pulling loads or installing a heavy 
implement. 
(1) Only use approved hitch points. 
(2) Limit loads to those which you can control safely. 
(3) Limit travel speeds so that you can control the tractor 

safely. 

(4) Do not turn too quickly. 
(5) Use care when backing up. 
(6) Install the amount of ballast recommended in the 

operator’s manual. 

 

 

 
Driving forward out of ditch or in muddy conditions, or up 
a steep slope, could cause the tractor to tip over 
backward. If the mud is deep enough it will keep the 
wheels from turning. Then, the tractor will rotate up and 
back around the axle very quickly. When stuck in muddy 
conditions, do not remove the implement or ballast 
weight. Always back out.
