Troubleshooting
SSimalitsiiu
Problem
Cause/Remedy
4. Engine stalls easily with mower engaged.
A.
Tractor ground speed,too fast.
B.
Engine speed too slow.
C.
Cutting height set too low when mowing tall grass.
Cut tall grass at maximum cutting height during first
pass.
D.
Discharge chute jamming with cut grass; cut grass
with discharge pointing toward previously cut area.
5. Excessive mower vibration.
A.
Blade mounting screws are loose; tighten to 50-60
foot-pounds of torque (68-81 N-m).
B.
Mower blades, arbors, or pulleys are bent and should
be replaced.
C.
Mower blades are out of balance; remove, sharpen,
and balance blades.
6. Excessive belt breakage occurs.
A.
Belt tension too tight. Readjust belt tension.
B.
Bent or rough pulleys. Replace.
C.
Using incorrect belt.
Figure 24. Troubleshooting Procedures (Cont'd.)
1.
Set parking brake and place transmission in
"NEUTRAL". Turn off lights and other elec¬
trical loads.
2.
Remove vent caps from both the booster and
the discharged batteries. Lay a cloth over the
open vent wells of each battery. These two ac¬
tions help reduce the explosion hazard always
present in either battery when connecting
"live" batteries to "dead" batteries.
3.
Attach one end of one jumper cable to the posi¬
tive terminal of the booster battery (identified
by a red color, "+" or "P" on the battery case,
post or clamp) and the other encf of same cable
to positive terminal of discharged battery. DO
NOT permit vehicles to touch each other, as
this could establish a ground connection and
counteract the benefits of the procedure.
4.
Attach one end of the remaining cable to the
negative terminal (black color, "—" or "N") of
the booster battery, and the other end to a bare
metal surface on the frame of your tractor
AWAY FROM the battery compartment (do
not connect directly to negative post of dead
battery). Take care that clamps from one cable
do not inadvertently touch the clamps on the
other cable. Do not lean over the battery when
making this connection.
Battery Replacement
A dead battery or one too weak to start the engine
may not mean the battery needs to be replaced. It
may, as an example, mean that the alternator is
not charging the battery properly. If there is any
doubt about the cause of the problem, see your
dealer. If you need to replace the battery, proceed
as shown in the battery cleaning procedure (figure
18).
Jump
Starting With Auxiliary
(Booster)
Battery
Jump starting is not recommended. However, if it
must be done, follow these directions. Both booster
and discharged batteries should be treated care¬
fully when using jumper cables. Follow exactly the
procedure outlined below, being careful not to
cause sparks:
Sk
WARNING
Never expose battery to open flame or
electric spark — battery action generates hy¬
drogen gas, which is flammable and explo¬
sive. Don't allow battery fluid to contact
skin, eyes, fabrics, or painted surfaces —
fluid is a sulfuric acid solution, which could
cause serious personal injury or property da¬
mage when working with battery.
