Husqvarna GTH2554XP 用户手册

Always observe safety rules when performing any main-
 te nance.

If tractor requires more than fi ve (5) feet to stop at highest 
speed in highest gear on a level, dry concrete or paved 
surface, then brake must be checked and adjusted, then 
brake must be adjusted.  (See “TO ADJUST BRAKE” in the 
Service and Adjustments section of this manual).

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

SPECIFICATIONS” 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 prevent fl at tires due to 
slow leaks, tire sealant may be purchased from your local 
parts dealer. Tire sealant also prevents tire dry rot and 
corrosion.

Be sure operator presence and interlock 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 depressed and attachement clutch control is in 
the disengaged position.

•         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.

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.

Your tractor has a battery charging system which is suf fi  cient 
for normal use.  However, periodic charging of the battery 
with an automotive charger will extend its life.
•      Keep battery and terminals clean.
•      Keep battery bolts tight.
•      Keep small vent holes open.
•      Recharge at  6-10 amperes for 1 hour.

NOTE: The original equipment battery on your tractor is 
maintenance free. Do not attempt to open or remove caps 
or covers. Adding or checking level of electrolyte is not 
necessary.
