CONSEJOS PARA SEGAR
• NO use cadenas de llanta cuando la carcasa
de la cortadora de césped esté colocada en
el tractor.
• La segadora debe estar nivelada en forma
adecuada para obtener el mejor rendimiento
al segar. Vea "PARA NIVELAR LA CAJA DE
LA SEGADORA" en la sección de Servicio y
Ajustes de este manual.
• El lado izquierdo de la segadora se debe usar
para recorte.
• Maneje de modo que los recortes se desc-
arguen en el área que ya ha sido cortada.
Mantenga el área de corte a la derecha del
tractor. Esto producirá una distribución más
pareja de los recortes y un corte más uniforme.
• Al segar las área grandes, empiece girando a
la derecha de modo que los recortes se des-
carguen, alejándose de los arbustos, cercos,
entradas de automóviles, etc. Después de una
o dos vueltas, siegue en la dirección opuesta,
haciendo virajes a la izquierda, hasta que
termine.
• Si el césped está demasiado alto, se debe
segar dos veces para reducir la carga y los
posibles peligros de incendio debido a los
recortes secos. Haga el primer corte re la ti va-
men te alto; el segundo a la altura deseada.
• No siegue el césped cuando está mojado. El
césped mojado taponará la segadora y dejará
montones indeseables. Per mi ta que se seque
el césped antes de segarlo.
• Siempre opere el motor con una aceleración
completa cuan do siegue para asegurarse
de conseguir un mejor ren di mien to y una
descarga apropiada de los materiales. Regule
la velocidad de recorrido seleccionando un
cambio lo su fi cien te men te bajo para obtener
un rendimiento de corte de parte de su sega-
dora y también la calidad del corte deseada.
• Cuando opere con accesorios, seleccione una
velocidad de recorrido que se acomode al ter-
reno y le permita obtener el mejor rendimiento
del accesorio que se está usando.

TRACTOR
Always observe safety rules when per form-
ing any main te nance.
BRAKE OPERATION
If tractor requires more than 5 feet (1,5 m)
to stop at highest speed in high est gear on
a level, dry concrete or paved surface, then
brake must be serviced. (See "TO CHECK
BRAKE" in the Ser vice and Ad just ments
section of this manual).
TIRES
• Maintain proper air pressure in all tires
(See the side of tires for proper PSI.)
• 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
flat 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.
OPERATOR PRESENCE SYS TEM AND
REVERSE OPERATION SYSTEM (ROS)
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
first 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 oper-
ate 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 drive in 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 engaged, any attempt
by the operator to drive in reverse should
NOT shut off the engine.
