Weed Eater 405209 Service Manual

Always observe safety rules when per form ing any main-
 te nance.

If tractor requires more than fi ve (5) feet to stop at highest 
speed in high est gear on a level, dry concrete or paved 
surface, then brake must be checked and ad just ed. (See 
“TO ADJUST BRAKE” in the Ser 

vice and Ad just ments 

section of this manual).

TIRES
•         Maintain proper air pressure in all tires (See “PROD UCT 

SPEC I FI CA TIONS” section of this man ual).

•      Keep tires free of gasoline, oil, or insect control chemi-

 cals which can harm rubber.

•     Avoid stumps, stones, deep ruts, sharp objects and 

other hazards that may cause tire damage.

NOTE: To seal tire punctures and pre vent fl at tires due to 
slow leaks, tire sealant may be purchased from your local 
parts dealer. Tire sealant also pre vents tire dry rot and 
corrosion.

Be sure operator presence and reverse operation sys tems 
are work ing properly.  If your tractor does not function as 
described, repair the problem immediately.
•      The engine should not start unless the brake pedal is 

fully de pressed, and the attachment clutch con trol is 
in the dis en gaged position.

CHECK OPERATOR PRESENCE SYSTEM
•         When the engine is running, any attempt by the op er a tor 

to leave the seat without fi rst setting the parking brake 
should shut off the engine.

•      When the engine is running and the at tach ment clutch 

is engaged, any attempt by the operator to leave the 
seat should shut off the engine.

•     The attachment clutch should never operate unless 

the operator is in the seat.

CHECK REVERSE OPERATION (ROS) SYSTEM
•      When the engine is running with the ignition switch in 

the engine "ON" position and the at tach ment clutch 
engaged, any attempt by the operator to shift into 
reverse should shut off the engine.

•      When the engine is running with the ignition switch in 

the ROS "ON" position and the at tach ment clutch en-
gaged, any attempt by the operator to shift into reverse 
should NOT shut off the engine.

For best results mower blades must be kept sharp.  Re place 
bent or damaged blades.

•     Raise mower to highest position to allow access to 

blades.

NOTE: Protect your hands with gloves and/or wrap blade 
with heavy cloth.
•      Remove blade bolt by turning counterclockwise.
•      Install new or resharpened blade with stamped "THIS 

SIDE UP" facing deck and mandrel assembly.

IMPORTANT: TO ENSURE PROPER ASSEMBLY, CENTER 
HOLE IN BLADE MUST ALIGN WITH STAR ON MANDREL 
ASSEMBLY.

•     Install and tighten blade bolt securely (45-55 Ft. Lbs. 

torque).

IMPORTANT:  SPECIAL BLADE BOLT HEAT TREATED.

NOTE:  We do not recommend sharp en ing blade - but if 
you do, be sure the blade is balanced.

Care should be taken to keep the blade balanced.  An un-
balanced blade will cause excessive vibration and even tual 
damage to mower and engine.
•      The blade can be sharpened with a fi le or on a grind-

ing wheel.  Do not attempt to sharpen while on the 
mower.

•      To check blade balance, you will need a 5/8" diameter 

steel bolt, pin, or a cone balancer.  (When using a 
cone balancer, follow the instructions supplied with 
bal anc er.)

NOTE:  Do not use a nail for balancing blade.  The lobes of 
the center hole may appear to be centered, but are not.
•         Slide blade on to an unthreaded portion of the steel bolt 

or pin and hold the bolt or pin parallel with the ground.  
If blade is balanced, it should remain in a horizontal 
position.  If either end of the blade moves downward, 
sharpen the heavy end until the blade is balanced.
