MAINTENANCE
Your Simplicity tractor has been designed and manufactured
to give you many years of dependable operation- In order
for it to give you efficient, trouble free service over a long
period of time the maintenance operations listed here must
be performed on a regular basis, The optional hour meter
provides an accurate method of determining when these ser¬
vices need to be performed.
A wide variety of attachments and accessories permit use of
your tractor throughout the year. BECAUSE YOUR TRAC¬
TOR IS A MULTI-SEASON TOOL, IT IS VERY IMPORT¬
ANT TO SERVICE THE ENGINE FOR THE SEASON If
WHICH IT WILL BE OPERATED. Be sure to change to
winter grade oil before making cold weather starts.
Whenever you are checking fluid levels in any area of the
tractor, the readings will be much more accurate if the trac¬
tor is setting on level ground. We have provided the Scheduled
Maintenance Chart on page 20 asa convenient means for you
to know .which services should be performed at various times.
You should, of course, refer to the detailed explanation of
how to perform each maintenance task until you are familiar
enough with it to perform it correctly from memory.
Refer to your Briggs & Stratton operating and maintenance
instructions for more specific detail on servicing the engine.
ORDERING REPLACEMENT PARTS
Figure 19. Checking the engine oil at ri^ht front of tractor.
Replacement parts required for performing maintenance
services or repair work should be purchased from your Sim¬
plicity dealer. Whan ordering parts be prepared to give him
the tractor and engine identification numbers. If yog have
not already recorded these numbers on the inside front
cover of this manual, we suggest that you do so now for con¬
venient future reference.
EVERY 5 HOURS OF OPERATION
INSPECT THE TRACTOR AND ENGINE: Make a
general Inspection of the tractor and engine Looking for loose
bolts, oil Leaks, low tire pressures, etc. A few minutes spent
correcting a small profflem could prevent a costly breakdown
later.
CHECK ENGINE CRANKCASE OIL LEVEL: See
figure 19. If the engine has been running, allow a minute or
two for the oil to drain down into the crankcase before
checking the oil level. Proceed as follows:
1. See figure 19. Turn the engine oil filler cap-dipstick (A)
counter-clockwise and lift it out,
Z Wipe the oil from the dipstick with a clean cloth.
3. Replace the filler cap dip-stick in the filler pipe and turn
the cap clockwise locking It into position.
4. Remove the filler cap dip-stick and check the oil level on
the dip stick,
5. If the oil is below the full line (B) shown in figure 19, add
enough oil to bring the oil Level up to the full mark- Use the
same grade and weight of Oil which is already in the engine.
DO NOT OVERFILL THE CRANKCASE.
6. R eplace the filler cap-dipstick (A) and tighten it securely.
EVERY 25 HOURS OF OPERATION
CLEAN TRANSMISSION 01L COOLER: See figure
20. Use a screw driver to remove plug (A). Inspect the oil
cooler (B) and if necessary remove any dirt, chaff or oil,
which may decrease the efficiency of the cooler. Dirt and
chaff collected on the outside of the cooler can usually be
brushed off after the engine has been stopped. Be careful not
to bend the coaler fins. If grass, chaff, or dirt collect between
the fins, it may be necessary to use air or water pressure to
blow it out. A non-fl amma ble solvent should be used to re¬
move any oil which may collect on the outride of the cooler.
In warm or dusty operating conditions, or when mowing dry
dry grass, the cooler may need to be cleaned more often to
prevent foreign material from restricting air flow through it.
CLEAN ENGINE FINS AND SCREEN: See figure
21. The blower screen (A) must be kept relatively free of
chaff, grass, etc., which would restrict the flow of cooling
air to the engine. Material which collects can normally be re¬
moved with a brush after the engine is shut off. The screen
may need to be cleaned more often when mowing dry grass.
Bee figure 23. All grass and chaff should be removed from the
engine fins {A}; C AUTI ON: TH E ENG1NE FINS ARE VE R Y
HOT AFTER THE ENGINE HAS BEEN OPERATED, DO
NOT TOUCH THEM UNTIL THE ENGINE HAS BEEN
ALLOWED TO COOL. NEVER SPRAY WATER ON A
HOT ENGINE.
