THE FIELD ARTILLERY JOURNAL<br />

If <strong>the</strong> battery is not tightly held it will become shaken to pieces<br />

under service conditions.<br />

Governor.—Is required by some engines and not by o<strong>the</strong>rs.<br />

Necessity <strong>the</strong>refor should be decided by circumstances.<br />

Speedometer.—One should be provided. Desirable for use<br />

in travelling by map.<br />

Horn.—This or o<strong>the</strong>r warning signal is desirable.<br />

Chains.—Particular attention should be paid to this point.<br />

Those ordinarily furnished with trucks are not good enough for<br />

maneuvering over bad ground. Suitable grouters should be<br />

provided for tractors.<br />

Winch.—Should be provided. A machine not ordinarily<br />

equipped with a winch can be so provided without much trouble<br />

if a machine shop is available by making a winch body that can<br />

be attached to one of driving wheels by removing hub cap.<br />

Speeds.—Specifications for speed depend on circumstances.<br />

The speed control should be satisfactory at all speeds and truck<br />

should run for long distances on low speed without excessive<br />

heating of engine or radiator.<br />

Tool Box.—Suitable box with lock should be provided.<br />

View.—The driver should be able to see sufficiently well for<br />

maneuvering without moving from his seat.<br />

Springs.—Should be tested by running machine over rocks<br />

several inches high, or o<strong>the</strong>rwise subjecting machine to shock<br />

for testing.<br />

Bolts, Nuts and Screws.—All except those of negligible<br />

importance should be secured by lock washers, cotter pins or<br />

o<strong>the</strong>r means. It is worth while testing this feature by running for<br />

a day over cobblestone pavement or similar road, if available.<br />

Engine.—Should be of sufficient power for <strong>the</strong> purpose<br />

required and should not be assumed to be sufficient merely<br />

because <strong>the</strong> truck is given a high rating. As an approximation,<br />

anything less than four cylinder, 4¼-inch bore, should not be<br />

considered for a truck rated at two tons. For hauling a section<br />

of heavy <strong>field</strong> <strong>artillery</strong> a 50-horsepower engine is about right<br />

for a tractor.<br />
