JOHN DEERE No, 4-A TRACTOR PLOW 
Long, conveniently-reached levers 
make is easy to control depth and 
leveling accurately. 
The power-lift is simple, and posi¬ 
tive. It will stand the hardest, 
roughest work. It will last far 
longer than any ordinary power 
lift. 
The land wheel, from which the 
power-lift operates, is solid and 
straight from tire to box on the 
inside; it does not pick up dirt or 
trash, thus it is a natural protection 
to clutch and driving parts. On a 
half turn of this wheel, the bottoms 
lift high and level—no digging into 
the ground or clogging with trash 
when turning the ends of the field. 
When the bottoms are lowered, 
they enter the ground point first 
and penetrate quickly to plowing 
depth. 
You Want Strong and Close-Fitting, Quick-Detachable Shares 
Bottoms on the John Deere are equipped with quick-detachable shares. The John Deere quick detachable 
device is different from others and has important advantages. 
You simply loosen one nut to remove a share; tighten the same nut and the share is on tight. 
The nut is large and fits on a large, heavy-thread draw-bolt. 
When drawn into place by turning the large nut, the John Deere quick-detachable share fits closely and stays 
tight—no loosening to give that “weaving” effect which increases draft and impairs work. 
You Want An Easily-Operated Plow 
You want a plow that can be operated with little effort on your part—a plow with no complicated mechanism— 
a plow of simple and positive adjustments. 
The John Deere meet those requirements. 
The hitch is quickly and accurately adjustable up and down and to the side.

JOHN DEERE DISC PLOW - SINGLE 
High-Grade Steel Discs Easily Adjustable 
for Width of Cut 
The discs, made of high-grade steel, are de¬ 
signed for good penetration and cut clean. The 
disc faces are smooth, no bolts projecting. 
Twenty-four inch discs are regularly supplied. 
Twenty-six inch discs are furnished on special 
order. 
The discs may be set to cut eight, ten or twelve 
inches. On the single-disc, the adjustable front 
furrow axle provides the means for changing the 
width of cut. On the double and triple-disc, the 
front disc’s width of cut can be changed by ad¬ 
justing the front furrow axle, while the change 
can be made for the other discs by removing the 
connecting bolts and changing the positions of 
the beams to each other, marks on the beams 
indicating the different positions. 
Bearings Keep Discs Revolving Freely 
The discs are equipped with high-speed chilled 
bearings, oil-tight and dust-proof. These bearings 
insure long wear and easy running—they keep the 
discs revoling freely. The hub and sleeve are full- 
chilled; the sleeve is removable and can be re¬ 
placed at small expense when worn. 
The oil tube is provided with a hard oiler which 
forces the hard oil down into the bearing, keeping 
long wear.
