Cub Cadet I-Beam Style - Manual (Page 285)

7-4
Bushel: One bushel equals 8 gallons.
Gasoline: We recommend regular unleaded gas.
Do not leave gas in tank over the winter unless
fuel stabilizer is used; start each season with fresh
gas (don’t use fuel that is over 4 months old). DO
NOT USE Gasohol that is more than 10% alcohol
or methanol.
Oil: Use SAE 30 or 10W-30 weight detergent oil
(not 10W-40). It is very important to change oil
after the first two hours of use in a new mower and
then after every 25 hours of operation. Always con-
sult owners guide for fill capacity.
Fuel Stabilizer: For all 2 and 4 cycle engines this
product allows for easy starts when put in full tank
of gas and stored during long periods of time.
Cutting Height: It’s not recommended to cut off
more than the upper third of the grass at one cut-
ting. In most grasses the cutting height should be
lower in the cool spring, higher in the hot weather
in heavily shaded areas.
Mowing Direction: During cutting, mow in a
counter-clockwise manner to prevent clippings
from being recycled into the cutting path. The cut-
ting blade isn’t forced to pick up wet clippings as it
mows the uncut grass. If mower wheels compact
the soil, leaving tracks, alternate the mowing pat-
tern each time you mow.
Collecting Clippings: Heavy clippings left on the
lawn can smother the grass, preventing needed air
and moisture from reaching the roots. Clippings
harbor lawn insects, disease, fungi, and are
unsightly. Mulching mowers do not cause this prob-
lem since the grass clippings are cut finely and
return nutrients to the soil.
Spark Plug: Should be changed every spring for
easier starting and engine efficiency.
Air Filter: Replace the air filter every year, more
often if needed.This helps the engine start easier,
run better, last longer and uses less gas.
Mower Blade: Worn blades should be replaced,
not only for the new cutting edge but also for the lift
designed into it that restores air turbulence. A worn
blade won’t cut well or bag, causes engine vibra-
tion, and loss of power.
ENGINE TERMS
Automatic Choke: Method of automatically prim-
ing the carburetor for surer starts.
Automotive Type Air Filter (Paper Type): A
larger filter area (90 sq. inches) than conventional
oil bath sponge filters. Will last longer and does a
better job keeping engine running cleaner, enhanc-
ing engine life. Requires little or no maintenance.
For dusty/sandy areas, a washable/reusable pre-
cleaner is available to extend the life of the paper
air filter.
Cast Iron Cylinder Liner: Provides better oil
retention and superior wear. Dissipates heat more
efficiently for longer engine life and lower mainte-
nance cost.
Mechanical Governor: Internal flyball weights on
the crankshaft automatically call for more fuel to
increase the engine’s output when more power is
needed, for example, cutting thick, tall grass, help-
ing to keep blade speed constant.
Mechanical Compression Release: A mechani-
cal device which acts on the camshaft to greatly
reduce internal air pressure during the starting
cycle, significantly reducing the effort required to
start the engine. It closes automatically during
engine operation to retain full power.
Operator Zone: The area behind the handle
where the user must be positioned when he oper-
ates the mower.
Overhead Valve Engine: Valves are located in the
head of the engine rather than in the cylinder block
itself. This enables the engine to develop more
torque (power) than a conventional “L-head”
engine with similar cubic inch displacement. It
allows the engine to run cooler and more efficiently
for longer life.
Polymer Gas Tank: Prevents rust and condensa-
tion in the fuel system.
Positive Lubrication: Oil is pumped to vital
engine parts when the engine is started. Lubricates
the engine with each turn of the crankshaft.
Horsepower: Horsepower is a technical term
referring to the rate at which an engine can perform
