Automotive Type of Transmission 
Entire Driving Mechanism, INCLUDING RATCHETS, runs in bath of oil 
TWO-PIECE MAIN AXLE 
The main axle is in two sections—one long and 
one short—and revolves in four roller bearings 
(2 single and 2 double). These roller bearings 
are made of high-grade steel and are equipped 
with split-type steel races. They are thoroughly 
lubricated from the central oil bath and require 
no attention. The ratchets are placed at the 
junction of the two sections inside the gear case, 
similar to the differential arrangement used in 
automobiles. Leather oil seals enclosed in metal 
cases prevent oil from leaking past the ends of 
the axles. Ground wheels are keyed solidly to 
the axle sections, thus eliminating end play, 
noisy ratchets, wabbling, and lost motion. 
LONG LIFE WITH QUIET OPERATION 
The gear case holds a full gallon of oil and is 
closed with a tight-fitting cover to exclude dirt 
and prevent oil leakage. The advantages of this 
type of construction are obvious. First, all run¬ 
ning parts of the mower, with the exception of 
the pitman, are automatically oiled and usually 
require no attention on the part of the operator 
throughout the season. Wear on the gears and 
bearings is reduced to a minimum, resulting in 
lighter draft and longer life. Noise and vibration 
are reduced to a surprising degree, all of which 
is due to the new type of power transmission, 
with all moving parts running in a bath of oil. 
Oil plugs in the top and bottom make it easy to 
drain, flush, and refill the gear case without 
removing the cover. 
The John Deere 
Spreader — the 
spreader with the 
beater on the axle 
—has only one-half 
as. many parts as 
the simplest spread¬ 
er heretofore manu¬ 
factured. All its 
working parts are 
mounted on the rear 
axle. It has no 
chains, no clutches 
and no adjustments. 
Being low down, it 
is easy to load.

The McCormick-Deering enclosed-gear mower 
is the finest machine of its kind ever built. Auto¬ 
motive principles of construction have been ap¬ 
plied to make it the outstanding achievement in 
the manufacture of mowing machines. While 
this remarkable mower is new to the trade, it 
has been thoroughly tried and tested under all 
conceivable conditions, both in this country and 
abroad. Improvements and refinements have 
been added until it truly represents “the last 
word” in mower construction and performance. 
ENCLOSED MECHANISM—RUNS IN 
BATH OF OIL 
The entire driving mechanism, including the 
drive gears, ratchets, and countershafts, is 
grouped compactly in one common chamber or 
gear case. Here a deep bath of oil completely 
envelops all moving parts and insures thorough 
lubrication. The pitman bearing on the flywheel 
and the pitman clasps are the only friction sur¬ 
faces not reached by the central oil supply. This 
arrangement of gears, power transmission, and 
lubrication is greatly superior to the ordinary 
type of mower with its open gears and ratchets 
in the wheel hubs,
