Advantage Of Caterpillar B.

Tests O1 motor plows we're made at
the, Klein Wanslebcn experiment sta.
ton in August 1913. Eight types Of
steam and gasoline machines entered
into this competition the final report
Of which was published by the German
government in January 1914. The fol-
lowing verdicts are taken from the OIL
cial summary; iii.
1.-THE two-engine system Of steam
plows represented by the Friederich
Kuers (and other) types has the ad.
vantage Of great steadiness of work but
the disadvantage that the tackle is
cumbersome to move about and that
heavy outlay is required on the plant
in comparison to the work done. This
system further lends itself only to a
limited extent to other work besides
blowing. The traction, engines are solid.
ly built and reliable and in consequence
of the low number of revolutions are
probably durable. During the main
trial the performance was limited in
quantity. During the trial OF resist
ance it was higher. The quality Of the
work was good. =. f,,E.
1.-THE International Harvester Com.
pany's 30 to so horse power motor with
S-furrow pillow Is easier to move about.
1t 10 suitable for moving and many
other agricultural operations besides
blowing. On slippery or very loose soil
there is danger of its coming to a
standstill through the wheels skidding.
The number of revolutions of the motor
Is moderate and its probable durability
is good. Its performance was very cool
both as regards quantity as well as
quality. ''"
1.-THE Holt Caterpillar motor tractor
system presents the advantage of great
traction power and consequently il is
relatively very reliable. On the other
hand its installation is expensive and
il Is somewhat cumbersome to move
about, The traction engine is cOmpli
Gated and, IL is anticipated, will he
very liable to wear out. Its perform
ance was very good, as to both quality
and quantity.
/ "The Universal As to 50-h.p. motor
pillow presented the advantages and dis.
advantages of the tractor system. Its
construction led to numerous Interrupt
tions to work. Its performance was
very good as to quality, but low as to
quantity, and the consumption of fuel
was high.
,"Poehl's Patent Motor Pillow, intend
ed to apply the tractor system to small
farms, did not show satisfactory re
liability. .--.
"Stock's motor pillow represented the
first machine built on the automobile
pillow system which offers the advantage
of low total weight and corresponding
low cost of installation. It's rel ability
on soft soils is greater than with the
tractors, with the exception of the
Caterpillar, The construction is good,
hut the number of revolutions OF its
motor is high and its probable duration
is limited. Its performance was suAi
Gent as regards quality and good as to
quantity.
1.-THE Wendeler Dohrns motor pillow
got a verdict of being Hhandy ant
solid The AGRA, designed for only
the heaviest work, was faulty in con
stTuctiOn. ...,,
'"The LII. O., Caterpillar and Stock
were the best auto motor machines in
the competition, and the Kuers vas the
best two engine steam pillow. Th" auto
pillow problem is different from that of
road machines and trucks. As the
weight of the Caterpillar Is reduced and
its working parts simPliied and stand
ardized greater possibilities are ahead
