“Super Twin” With Four Gangs and Sulky 
F ROM the most complete line of power mowing equipment, Coldwell can furnish a model to suit every need and every budget. The 
accumulated experience of thirty-five years of power mower building is reflected and built into every Coldwell machine. Each 
model and accessory has been exhaustively field-tested, to best cope with specific turf conditions. 
SPECIFICATIONS 
General—Coldwell Power Mowers are roller driven, with dual 
control chain drive providing independent power to drive roller 
for traveling and to the cutting unit for mowing. Governor can

speed at low, medium and high. Hand throttle controls accelera¬ 
tion at various speed positions. Frame of structural steel, electric 
arc welded. 
Engine—Completely made by Coldwell. Four cycle, water- 
cooled by radiator and fan. Tillotson Carburetor with air cleaner; 
Bosch fly-wheel type Magneto; Oil pump for lubrication; Steel-

or 514 H.P., N.A.C.C. Rating; Single Cylinder develops 1.6 H.P. 
at 1200 R.P.M. or 2% H.P., N.A.C.C. rating. 
Transmission—Enclosed in Metal Housing. Closed Type, 
self-adjusting spring loaded with cone friction. Clutches lined 
with Asbestos replaceable brake lining. Dual control provides 
independent power through the chain drive to Revolving Cutter 
and to Drive Roller. 
Drive Rollers—Two section, full width, with corrugations cast 
in. Equipped with differential to prevent marring turf when 
turning. Pinions and Gears of steel forgings beveled and cut, 
completely enclosed in dirt proof housing. Can be furnished 
rubber-covered. 
Cutting Unit—Full Floating, demountable front with sectional 
guard roller, fastened to the steel channel frame by push arms; 
adjustable caster rollers in front of the cutting unit can be regu¬ 
lated for various heights of cut; pivots freely and conforms readily 
to uneven surfaces. The Revolving Cutter (five or seven blades) 
is engine driven to assure an even, smooth cut; blades are fastened 
to double-edged flanges; shaft revolves on double row ball bear¬ 
ings. Both revolving cutter blades and bottom knife are heat- 
treated and oil-tempered. 
SUPER TWIN CYLINDER MODELS 
The Super Twin Mowers house an abundance of power, are de¬ 
signed for large areas, and are particularly suited for the job of 
mowing, rolling and trimming when capacity performance at the 
very minimum of time and expense is required. Cutting widths of 
25" to 30" are available with a mowing capacity of 4 to 7 acres per 
day. Will travel grades up to 45 per cent, and has a regular travel¬ 
ing speed of 2 to 5 miles per hour. Two gallons of fuel are sufficient 
to operate the machine for 8 hours. Tremendous power and 
traction makes possible larger width of cut by the addition of extra 
cutting units, as shown above. Grades offer no difficulty and with 
the sulky attached, the operator as well, may be transported. 
"Super Twin Thirty”—30" cut.$385.00 
“Super L Twin”—25" cut. 335.00 
SINGLE CYLINDER MODELS 
Similar in most respects to the "Super Twin” but of slightly 
lighter construction, and naturally, with a lower power range, 
Coldwell single cylinder mowers are ideal for the small and medium 
sized area where the demand for unusual power will not be en¬ 
countered. Single cylinder mowers have a cutting capacity of two 
to seven acres per day depending on width of cut. One gallon of 
fuel per ten hours is sufficient to operate a single cylinder model at 
a traveling speed of 2 to 4 M.P.H.

“L Junior”—25" cut. 260.00 
“Coldwell Cub”—21" cut. 215.00

of wheel or roller drive.

and caster rollers, at a slight additional cost.
