THE COLDWELL CUB MOTOR MOWER 
The Coldwell Cub is a light, substantially built power lawn mower 
with a 21-inch detachable front cutting unit and a full width drive roller 
Separate clutches control the cutting unit and the traction roller. The 
clutch levers are conveniently located on the handle and can be engaged 
or disengaged with one finger. The drive roller is divided and is driven 
through a differential so that sharp turns can be made without marking 
the lawn. Where ground conditions require, wheels can be substituted 
for the drive roller, making a wheel type mower but retaining the ad¬ 
vantages of a removable front cutting unit. 
The front cutting unit makes it possible to cut close to trees or walls 
so that a finished job can be done without the use of a hand mower. 
The cutting unit can be removed for sharpening or repair without loosen¬ 
ing up the cross members of the frame or cutting unit. 
The engine and transmission are mounted on a steel frame in a per¬ 
fectly accessible position and located so the mower is in lateral balance. 
The engine has been specially designed for tnis mower. Not being 
limited to the general purpose engines offered on the market, it has been possible to incorporate the features required 
for this exacting heavy duty service. The engine is 2 K-inch bore, 3-inch stroke and at 1200 revolutions per minute 
develops 1 K brake horse power. 
The cylinder is water cooled with fan and radiator so that full load can be carried continuously in hottest weather. 
Note particularly that this is a horizontal engine which give a low center of gravity and aids in obtaining a perfect 
balance. An automobile type carburetor is used with a gasoline tank large enough for eight hours use. A constant 
speed is maintained by a fly ball governor mounted in the fly wheel. The governor parts are sturdy and covered 
so that they will not be deranged or damaged in handling. 
One and one half pints of oil poured into the crank case supply lubrication for all the engine parts for several days. 
Oil is raised from the oil pan by a pump and circulated to the bearings and cylinder. Splash lubrication is NOT 
used as it is unreliable in an engine subjected to such violent vibration and tipping, as is encountered in cutting rough 
lawns. Ignition is supplied by a Bosch high-tension fly wheel type magneto mounted directly on the crank shaft. 
These magnetos have been developed for outboard motors and are specially water-proofed. The crank shaft is 
mounted on two large Timken tapered roller bearings. This is a feature never before incorporated in an engine of 
this size, but it is warranted in view of the exacting service required. These bearings are guaranteed for the life 
of the engine and will be replaced if they fail for any reason. 
The friction clutches are of the dry place spring loaded type almost universally used on automobiles. Each clutch 
is separately controlled from the handle and when engaged a spring forces the disc up to the drive plate. No adjust¬ 
ment is needed as the spring follows up any wear on the moulded asbestos clutch lining. The power is transmitted 
through hardened roller chain. Particular attention has been given to making the cutting unit rigid and accessible. 
Note that there are THREE heavy tie rods and a rigid.knife bar to hold it in alignment. The knife bar adjustment 
is on the outside and the wiper bearings have a simple adjustment on the outside of the frame. A Zerk grease gun 
furnishes efficient lubrication for all the bearings outside of the engine. 
In this machine we realize our ideal of a light, strong, easily handled mower, so simple that an inexperienced man 
can understand and operate it. It is made light and strong by using steel and malleable iron where best adapted. 
Flexibility in maneuvering is obtained by proper distribution of weight and mounting on a large drive roller and casters.

THE COLDWELL MODEL “L” TWIN MOTOR 
LAWN MOWER AND ROLLER 
FLEXIBLE - VERSATILE - DEPENDABLE 
A most important development in Coldwell Motor Mower construc¬ 
tion is the feature of mowing and rolling simultaneously, which is in¬ 
corporated in the Model “L.” The gentle rolling with each cutting 
imbeds the earth around the roots of the grass and assures a sturdy 
growth. This is maximum efficiency at a minimum of cost. 
The “two operations in one” are done with half the labor, in half the 
time, at half the outlay. Without the Gang Unit attachments, the 
Model “Lmows and rolls four to six acres per day on a gallon of gaso¬ 
line. With the Gang Units attached, increasing the cutting width, from 
25 to 60 inches, the capacity of the Model “L”is more than doubled. 
Simple and economical to operate, with an abundance of reserve power 
for extreme grades and ever dependable, the Coldwell Model “L” Motor 
Lawn Mower and Roller is a machine which meets, in every respect, 
the most exacting lawn requirements. Particularly suitable for small 
estates, parks, cemeteries, school and club grounds. The Model “L” 
is also useful for separate rolling of tennis courts and close fine cutting 
on putting greens. 
The Model “L” is a combination motor lawn mower and roller designed for simple, economical and dependable 
performance. It is powered with a Fuller & Johnson, 3 % h. p., 4-cycle, water cooled motor with radiator and fan. 
The cutter knives and full traction roller are each independently driven direct from the motor and each has its sepa¬ 
rate clutch and control lever. The full floating cutter front conforms readily to the uneven surface of the ground. 
Motor and all working parts are protected from flying grass and dirt. Forced feed lubrication with “Allyn-Zerk” 
automatic grease gun. Gears are enclosed and run in oil. Finest roller chain with provision to take up wear. A 
fully guaranteed and thoroughly dependable motor lawn mower and roller.
