D URING 12 years of service Wallis 
principles have proven above all 
else the attribute of constancy. We have 
established the incontestable fact that 
Wallis engineering is basically right—• 
that this tractor is built to easily shoulder 
the strains of heavy farm work. 
This important result is not a matter 
of chance. Wallis engineers have de¬ 
veloped it by building on a basis of pure 
quality—by creating new standards and 
blazing new trails in tractor designing. 
The Wallis owner knows the result. 
He has seen it in a sweet-running, 
powerful machine, which goes on day 
after day without faltering—a machine 
which serves him faithfully and teaches 
him the real meaning of tractor economy. 
Any Wallis owner will point to his 
tractor with pride. He will show you the 
highly developed valve-in-head motor. 
He will point to the patented“U” frame— 
the lightest yet sturdiest foundation ever 
built into a tractor. It saves many pounds 
of needless weight—and practically elimi¬ 
nates vibration. Other important develop¬ 
ments he will point out. For instance, the 
cut and hardened steel gears which run 
in dust-proof cases in a constant bath of 
clean oil; the removable cylinder sleeves 
which save the heavy cost of reboring 
cylinders and of new pistons if a cylinder 
is scored; machine finished combustion 
chambers—a refinement used only in a 
few of the finest automobiles. 
The Wallis owner speaks of these things 
with enthusiasm because he knows that 
the rough work and terrific strains a 
tractor must overcome require even 
better engineering and materials, more 
careful and accurate workmanship than 
an automobile or truck. And he knows 
that his Wallis serves him faithfully be¬ 
cause it is built upon such standards. 
Today there is only one tractor ofWallis 
quality—and that is the Wallis. It rep¬ 
resents a class entirely its own—a class 
extending back for 12 years when Wallis 
first proved that in quality—not bulk— 
is the only real tractor strength obtained. 
Wallis owners know that the tractor is 
a perfected thing—a profitable invest¬ 
ment. Wallis has proved it. 
More and more men each day are 
finding in this quality machine the answer 
to their question “What Tractor?” The 
demand is heavy right now. This very 
day is the time to investigate, if you 
want a Wallis.
