Elitist. 15. The front wheels of the<br />
<strong>Farmall</strong> 20 with one wheel <strong>and</strong> the<br />
bolster section cu t away to silow the<br />
high-grade construction of these<br />
parts. The construction in the F-30<br />
is the same in principle.<br />
Illust. 16. The <strong>Farmall</strong> 20 oil pump.<br />
It extends down into the oil comp<br />
<strong>and</strong> pumps oil through the oil filter<br />
directly to connecting-rod dips <strong>and</strong><br />
to the governor <strong>and</strong> cam shaft<br />
bearings.<br />
Many Good <strong>Farmall</strong> Features<br />
you can't see ... they Show up<br />
in added Years of tractor life<br />
THE nearest <strong>Farmall</strong> owner can tell you what the <strong>Farmall</strong> will do in<br />
the field, how many acres he can cultivate in a day, how easy the<br />
<strong>Farmall</strong> is to h<strong>and</strong>le, how steady it is on the belt, <strong>and</strong> how little it<br />
costs to keep the <strong>Farmall</strong> going. But not all <strong>Farmall</strong> owners can tell you<br />
all that is back of the perfection of <strong>Farmall</strong> performance, or what it is<br />
that makes <strong>Farmall</strong>s last so long.<br />
Yet the features back of the <strong>Farmall</strong> record are not secret. It's just<br />
that there are so many of them that are hidden inside the tractor. It's what<br />
these features add up to that makes a <strong>Farmall</strong> what it is.<br />
For instance, you can't see the thirty-three ball <strong>and</strong> roller bearings in<br />
a <strong>Farmall</strong> 20—that is, not without tearing the tractor down. If you could<br />
see them you still could not see the fine quality of steel <strong>and</strong> the precision of<br />
workmanship that went into those bearings, much less the rigid inspections<br />
they have to pass before they can get into a <strong>Farmall</strong> tractor.<br />
You can't tell that the <strong>Farmall</strong> has a ball-bearing crankshaft just by<br />
looking at the outside, but you know it's got something from the way the<br />
engine operates <strong>and</strong> the ease with which it can be started.<br />
You can't see the removable cylinder sleeves nor the quality of the<br />
gears in the transmission <strong>and</strong> final drive.<br />
The high quality steels used in the manufacture of the <strong>Farmall</strong> are<br />
made in the Harvester Company's own factories, where uniformity of<br />
product is under Harvester control. All working parts are turned, ground,<br />
or otherwise worked to such exact dimensions that it is necessary to have<br />
special equipment for measurement. The ideal balance of weight <strong>and</strong> power<br />
in the <strong>Farmall</strong> is something you cannot see, although you soon discover it<br />
in the field. You can't see the dust seals which keep oil in <strong>and</strong> dirt out, thus<br />
protecting the tractor against wear by dirt or grit.<br />
There are many other features of <strong>Farmall</strong> construction, especially with<br />
reference to quality of materials, that you cannot see. You only know<br />
they are there because <strong>Farmall</strong> performance<br />
<strong>and</strong> <strong>Farmall</strong> stamina prove it. These features<br />
not only make for length of life but<br />
assure economical operation through elimination<br />
of friction, proper protection of<br />
working parts, <strong>and</strong> scientific utilization of<br />
the different grades of fuel. To be sure of<br />
quality in the tractor you buy, be sure that<br />
there is a record for quality back of it.<br />
Illust. 17. The steering worm <strong>and</strong> worm<br />
wheel. A shows the splined end of the<br />
bolster shaft. When the teeth engaging<br />
the worm become worn the worm wheel can<br />
be turned on the shaft to engage unworn<br />
teeth, thus multiplying the life of the worm<br />
wheel. B is the irreversible steering worm<br />
which makes the <strong>Farmall</strong> steering wheel so<br />
easy on the operator's arms. C is a rawhide<br />
spring-loaded oil seal, the best device ever<br />
made for keeping oil in <strong>and</strong> dirt out. D is<br />
the ball bearings at the end of the steering<br />
shaft <strong>and</strong> which is one of the reasons for the<br />
quick response of the steering wheel.<br />
Illust. 18. There are three bearing<br />
cages in the <strong>Farmall</strong> transmission. Here<br />
we see the countershaft with bearing<br />
cage removed, allowing the shaft <strong>and</strong><br />
its gears to be raised out of the transmission<br />
case.<br />

Illust. 19. The power take-off which is a regular<br />
feature on all Farman tractors. Note that it is located<br />
most convenient ly with relation to the various<br />
machines the mechanisms of which are driven by<br />
the power take-off.
