means of the Depth Adjustment Knob (Fig 20), Moving
the Knob clockwise (/'_&) raises the mower (Fig 19)
Moving the Knob counterclockwise (_) lowers the mower,

been cut Have the cut area to the right of the machine
This will result in a more even distribution of clippings and
more uniform cutting When mowing large areas (Fig 21)
start by turning to the right so that the clippings wtl be
discharged away from shrubs, fences, driveways, etc After
two or three rounds, mow in the opposite direction making
left hand turns until finished If grass is extremely tall, it
should be mowed twice The first time cut re[atively high,
The second time to the desired height, The left hand side
of mower should be used for trimming, Use the Runner on
the right hand side as guide; the blade cuts approximately

1When grinding, care should be taken to maintain blade bal-
ance and the blade should be checked for proper balance
before reinstallation on mower_ Unbalanced or bent blade
will cause excessive vibration when running, and eventual
damage to mower or engine, Replace bent, damaged or un-
balanced blades=
To cbeck Blade balance, drive a nail into a beam or wall.
Leave about one inch of the straight nail exposed. Place
Center Hole of clean Blade over the head of the nail (Fig.
24). NOTE: CENTER HOLE OF BLADE ON NAIL IF
BLADE IS PROPERLY BALANCED, BLADE SHOULD
REMAIN IN POSITION SHOWN IN FIG, 24. IF EITHER
END OF THE BLADE MOVES DOWNWARD, BLADE IS
NOT BALANCED AND MUST BE REPLACED
2_ To ensure satisfactory operation, it is recommended that
before the start of each mowing season, the old blades be
discarded and replaced with new blades. Mower blades can
be purchased at any Sears Service Center/Departments and
most Sears Retail Stores

For best results mower blades must be kept sharp. The blades
can be sharpened with a few strokes of a file or on a grinding

Under normal usage the Mandrels should require lubrication
after every 50 hours of operation and at the end of each sea-
t son. Each Mandrel should be filled with grease (six shots) thru
the Grease Fitting located between Mower Blade and under-
side of the Mower Housing (Fig. 32), Wipe fitting clean be-
fore greasing, Use high performance, extreme pressure lubrica-
ting grease. Amdex No. 1 EP or equivalent, This grease may be
obtained by ordering thru your nearest Sears Repair Parts De-
\ partment, Part No. 2557R or equivalent,
To keep your tractor running better, longer; perform nec-
essary service using the following Maintenance Schedule.
Each time you start your tractor, check your Ammeter (Fig
33). The needle should move towards the + (charging) mark
indicating the battery is being charged asyou operate the trac-
tor The headlights will not show a discharge on the ammeter
because they are not connected to the battery (they have their
own electrical source, see page 23). If you have a lift motor
connected it will show a discharge when being operated°
