Thousands of farmers in all parts
Of the country use gasoline engines as
a source Of at least part Of their
power. The number in every branch
Of farming is increasing rapidly. From
the production Of crops to their har-
vest and preparation for sale, and
even their transportation to market.
the gasoline engine facilitates the
business of farming. Tractors. gas
engines to run belt machinery and mo.
tortrucks are enabling farmers to in
crease their operations. It is, there
fore, good business on the part Of the
farmer to use them whenever time, la
Dor and costs can be reduced.
Though the gas engine, whether the
stationary type, tractor, truck or au-
tomobile,. is a great labor saver when
operated efficiently, it is also at times
the cause of a great labor waste. Often
large crews hired to help with thresh-
ing, hay baling, cutting ensilage, ETC.,
draw full wages for hours spent in
idleness owing to inefficient handling
Of the engine. A man will sometimes
spend Auch more time and energy in
starting a gas engine to pump water
for stock. run a milking machine or
Tor some other similar purpose, than
would be required to do the work by
hand. Such lost time is to d great ex-
tent preventable. Gas engines are not
difficult to operate. and delays from
engine trouble are usually due to the
operators lack of knowledge Of some
Of the details essential to proficient
operation, say specialists Of the United
States Department Of Agriculture.
Keep Engines In Repair.
The first essential in gasoline engine
operation is to keep 1t in good repair,
say the specialists. All catalogues
and directions furnished by the manu-
facturer should be studied carefully.
Most manufacturers publish instruc-
tions on the care and operation Of the
engines they manufacture, and In or
der to get the most satisfactory re-
suits from an engine the owner should
study and put into practice these in-
structi0ns.
Every one who operates gas en-
gine should learn first to stop and rea-
son as to the probable cause Of any
trouble which develops. In tracing
trouble definite system should be
followed. When an engine refuses to
start the trouble will, with Z very few
exceptions, be due to some Interrupt
tion Of the supply or the proper mix
ture Of gas and air, or to the failure
Of the electrical system which fur
nishes the spark to fire the com
pressed mixture. Every system to To-
! cate trouble should take these two
points into consideration. a
