FUSE
WARNINg
Before servicing, repairing, or inspecting, always disengage PTO
(Blade Engage knob), set parking brake, stop engine and remove key
to prevent unintended starting.
A fuse is installed in your tractor's wiring harness to protect the trac-
tor's electrical system from damage caused by excessive amperage.
If the electrical system does not function, or your tractor's engine will
not crank, first check to be certain that the fuse has not blown. It is
located under the hood, mounted behind the top of the dash panel on
the support bar.
CAUTION
Always use a replacement fuse with the same amperage capacity as
the blown fuse.
TIRES
WARNINg
Never exceed the maximum inflation pressure shown on the sidewall
of the tire.
Refer to the tire sidewall for exact tire manufacturer's recommended or
maximum psi. Do not overinflate.
Uneven tire pressure could cause the cutting deck to mow unevenly.
CHANgINg THE TRANSMISSION DRIVE
bELT
Several components must be removed and special tools used in order
to change the tractor's transmission drive belt. See a Sears or other
qualified service dealer to have the transmission drive belt replaced.
ENgINE MAINTENANCE
WARNINg
Before performing any maintenance or repairs, disengage PTO
(Blade Engage knob), set parking brake, stop engine and remove key
to prevent unintended starting.
Checking the Engine Oil
Only use high quality detergent oil rated with API service classification
SF, SG, SH, or SJ. Select the oil's SAE viscosity grade according to
the expected operating temperature. Follow the chart below.
Colder
5W20

SERVICE AND MAINTENANCE
Warmer
SAE30
Although multi-viscosity oils (5W20, 10W30, etc.) improve starting
in cold weather, they will result in increased oil consumption when
used above 32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
To check the engine oil, proceed as follows:
1. Ensure that the tractor is on a level surface.
2. Clean the oil fill area of any debris.
3. Remove the dipstick and wipe with a clean cloth.
4. Insert and tighten dipstick.
5. Remove the dipstick and check the oil level. It should be at the
Full mark on the dipstick. See Figure 19.
6. If low, add oil slowly into the engine oil fill. Do not overfill. After
adding oil, wait one minute and then recheck the oil level.
Do not overfill. Overfilling with oil may cause the engine to not start,
hard starting, or engine smoking. If over the FULL mark on the
dipstick, drain oil to reduce oil level to FULL mark on dipstick.
7. Replace and tighten dipstick.
