work. The larger the horsepower rating of an
engine, the greater is its ability to handle the job.
Solid State Ignition: Solid state circuitry elimi-
nates points and condensers in conventional igni-
tion systems, which become less efficient and wear
out. A self-contained module eliminates moving
parts. In addition, it creates a hotter spark for more
dependable starting. Eliminates costly electrical
tune-ups. Simply change the spark plug.
Top Breather: Prevents oil overflow and maintains
lubrication of vital parts when mowing alongside
steep grades in either direction at any safe angle.
Muffler Deflector: Protects operator. Deflects the
exhaust away from the operator.
Extended Oil Fill: Makes it easier to add oil to
engine. Long tube extends to top of engine. Many
extended oil fills feature automotive style dipstick.
Industrial Commercial Engine: Features rugged
cast iron sleeves, heavy-duty dual element air
cleaner, and heavy duty valves for extended
engine life.
Pre-Cleaner For Air Filter: Is recommended in
dusty, sandy conditions, and extends the life of the
air filter, more economical.
Spark Plug Boot: Keeps spark plug clean and
protects the engine from shorting out when contact
is made with shrubs or trees. Rubber boot com-
pletely covers spark plug.
Counter-Balanced Engine: Counterweights are
added to the crankshaft of the engine so that when
the piston moves in one direction, the counter-
weight moves in the opposite direction, reducing
vibration for smoother running.
Displacement: As with automobiles, the only way
to accurately compare their various engines is to
compare their various displacements. The dis-
placement of an engine is measured in cubic centi-
meters of cubic engines. Displacement is the
measure of the difference in cubic area of the cylin-
der when the piston has been fired all the way
down and when it is all the way up. It is the area in
which the explosion is made. Thus, the greater this
area, the more power is generated.
TERMS FOR
HYDROSTATIC TRANSMISSIONS:
Axial Piston: Type of design for hydraulic motors
and pumps in which the pistons are arranged par-
allel with the spindle (input or output shaft).
Bantam Duty: A descriptive term relating to the
product capacity (meaning: light duty).
Bypass Valve: A valve whose primary function is
to open a path for the fluid to bypass the motor or
pump. Also referred to occasionally as the free-
wheel valve or dump valve.
Case Drain Line (Return Line): A line returning
fluid from the component housing to the reservoir.
Cavitation: A concentrated gaseous condition
within the fluid causing the rapid implosion of a
gaseous bubble.
Center Section: A device that acts as the valve
body and manifold of the transmission.
Charge Pump: A device that supplies replenishing
fluid to the fluid power system (closed loop).
Charge Pressure: The pressure at which replen-
ishing fluid is forced into a fluid power system.
Charge Relief Valve: A pressure control valve
whose primary function is to limit pressure in the
charge circuit.
Check Valve: A valve whose primary function is to
restrict flow in one direction.
Closed Loop: A sealed and uninterrupted circulat-
ing path for fluid flow from the pump to the motor
and back.
Decay Rate: The ratio of pressure decay over
time.
End Cap: See “Center Section”
Entrained Air: A mechanical mixture of air bubbles
having a tendency to separate from the liquid
phase.
Gerotor : A positive displacement pump frequently
used as a charge pump.
