Safety Instructions 

6.  Prolonged exposure to loud noise can cause 

impairment or loss of hearing.  

Operator hear-

ing protection is recommended.

 Wear a suit-

able hearing protective device, such as earmuffs 

or earplugs.

7. 

Keep all protective shields and safety devic-

es in place.  

If a protective shield, safety de-

vice, or decal is damaged, unusable, or missing, 

repair or replace it 

before

 operating the ma-

chine.

8. 

Be sure interlock switches are functioning 

correctly,

 so the engine cannot be started un-

less the Forward Speed Control lever is in the 

NEUTRAL-PARK

 position, the PTO clutch is in 

the 

DISENGAGED

 position, and the Parking 

Brake is in the 

ENGAGED

 position.  Also, the 

engine should stop if the operator lifts off the 

seat with any one or more of these controls in 

the operating position:  (1) Forward Speed 

Control (FSC) out of 

NEUTRAL-PARK,

 (2) PTO 

Clutch 

ENGAGED,

 or (3) Parking Brake 

DISEN-

GAGED.

9. 

Handle gasoline with care.

  Gasoline is highly 

flammable and its vapors are explosive:

a.  Use an approved fuel container.

b.  Never add fuel to a running engine or hot 

engine (allow hot engine to cool several 

minutes).

c.  Keep matches, cigarettes, cigars, pipes, 

open flames, or sparks away from the fuel 

tank and fuel container.

d.  Always fill the fuel tank outdoors using care.  

Fill to about one inch from the top of the 

tank.  Use a funnel or spout to prevent spill-

ing.

e.  Replace the machine fuel cap and container 

cap securely and clean up any spilled fuel 

before starting the engine.

10. 

Never attempt to make any adjustments 

while the engine is running,

 except where 

specifically instructed to do so.

11.  The electrical system battery contains sulfuric 

acid.  Avoid any contact with skin, eyes, and 

clothing.  Keep the battery and acid out of reach 

of children.

  WARNING

This product can expose you to chemicals 

including Di-(2-ethylhexyl) phthalate which 

is known to the State of California to cause 

cancer, and Di-(2-ethylhexyl) phthalate, 

which is known to the State of California  

to cause birth defects or other reproduc-

tive harm. For more information go to  

www.P65Warnings.ca.gov.

12.  Before operating an implement, become familiar 

with the location and function of all operator 

controls. Knowing the location, function, and 

operation of these controls is important for safe 

and efficient operation.

OPERATING

1. 

Operate the machine only in daylight

 or in 

good artificial light with good visibility of the area 

being bladed.

2.  Sit on the seat when starting the engine and 

operating the machine.  Keep feet on the deck 

or implement footrests at all times when the 

tractor is moving and/or the implement is oper-

ating. 

 Never operate the tractor without a 

deck or imple ment installed.

3.  For a beginning operator, 

learn to steer (ma-

neuver) the tractor with a slow engine speed 

before attempting any implement oper ation.

  

Be aware that, with the front mounted imple-

ment configuration, the back of the tractor 

swings to the outside during turns.

  DANGER

Do not operate around overhanging tree 

branches or bushes at the same height as 

the operator’s torso and head where inad-

vertent contact may cause injury.

4.  Remember, for an emergency stop, the forward 

motion of the tractor can always be stopped by 

pulling the Forward Speed Control (FSC) into 

the 

NEUTRAL-PARK

 position.

5.  In case the transmission drive belt breaks 

during operation, and if the machine is on a 

slope, the machine will freewheel down the 

slope.  

To maintain control,

 immediately (1)
