WARNING: This tractor is equipped with
an internal combustion engine and should not
be used on or near any unimproved forest-
covered, brush-covered or grass-covered
land unless the engine’s exhaust system
is equipped with a spark arrester meeting
applicable local or state laws (if any). If a
spark arrester is used, it should be maintained
in effective working order by the operator.
In the state of California the above is required
by law (Section 4442 of the California Public
Resources Code). Other states may have
similar laws. Federal laws apply on federal
lands. A spark arrester for the muffler is
available through your nearest Sears service
center (See ENGINE ASSEMBLY section of
this manual).

ENGINE
Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been ob-
tained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among
other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products
on which engines are placed and the variety of environmental issues applicable to operating the equipment, the
gas engine will not develop the rated gross power when used in a given piece of power equipment (actual “on-site”
or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner,
exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (tem-
perature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs
& Stratton may substitute an engine of higher rated power for this Series engine.
