Jacobsen Power Mowers Are Used on 
America’s Finest Lawns 
The "4-ACRE 
// 
Many estate owners do not realize that to mow lawns by hand is today quite 
obsolete and far more costly than to buy a Power Mower and depreciate it over a 
period of years. Instead of paying the annual costs of hand-mowing, an invest¬ 
ment in a good Power Machine will pay dividends from the moment of purchase. 
Introduced in 1921, the Jacobsen “4-Acre” has each year entrenched more 
firmly its position as the all-round favorite in the heavy-duty class. Year by year 
the “4-Acre” has been refined in details of construction, and major improvements 
have been added from time to time until it is far more capable and efficient today 
than it was in the early years that built its enviable reputation. This true-and- 
tried machine has a cutting width of 24 inches. It is a Mower that meets all 
conditions at all times. 
Wherever cutting width is the controlling factor, the 30-inch model of the 
“4-Acre”—a brand-new development—adds 25 per cent to the capacity of the 
standard 24-inch size, and without perceptible increase in operating cost. 
The “SIMPLEX” 
The Jacobsen “Simplex” meets the demand for a 
small, quality-built Power Mower at a low price. It is 
ideal for suburban homes, small parks, public grounds, 
cemeteries, and estates, or in circumstances where in¬ 
vestment must be kept at a minimum, and the amount 
of mowing does not demand the larger heavy-duty 
Jacobsen models. 
The “Simplex” is not just a Hand Mower with 
adapted power. It is built as a Power Mower from the 
ground up and designed for easy, simple, efficient 
mowing. Despite its low cost it embodies such Jacob¬ 
sen features as chrome-nickel steel reel mounted 
Timken adjustable roller bearings, safety 
clutch in the reel drive and bevel gear 
auto-type differential. It has the strength 
and stamina to insure long, repair-free 
service. Its light weight, short turning 
radius and compactness permit its speedy, 
handy operation among trees, on hillsides 
and terraces and other hard-to-get-at 
places. And it is so simple in construction 
that even a boy can operate it. It has a 
20-inch cutting width. Its net weight is 
153 pounds. 
The “STURDEX” 
The Jacobsen “Sturdex” is a powerful light¬ 
weight machine priced to provide large capacity 
mowing at a low initial cost. Its design is based 
on that of the “Simplex”—proved by years of 
actual field use under the most severe conditions. 
But the “Sturdex” has been built for heavy-duty 
work. It is powered with a Jacobsen-built motor 
developing full 1 J^-horse-power at normal operat¬ 
ing speed. Heavy side frames supported by 
three sturdy cross-members give it unusual 
rigidity. Tough, weedy grass growths are no 
problem to this Mower. Operation of the “Stur¬ 
dex” is made easier by separate traction and reel 
clutches. These are of approved design—both 
being smooth working and positive in action. 
This feature provides Free-Wheeling of the 
Mower when the clutches are disengaged. 
The weight of the “Sturdex” is exception¬ 
ally well balanced to facilitate handling. It 
can be operated in close corners, around trees 
and other obstructions, on side bills and steep 
grades with the utmost ease. This Mower has 
a 24-inch cutting width and a net weight of 
227 pounds. 
The “ESTATE 20” 
Here is just the Mower for those who have lawns of moderate size and who take pride in 
fine, smooth turf, perfectly groomed by frequent cutting. Having no wheels outside the 
frame, this Mower will cut close to trees or other solid obstructions and will overlap the 
edges of spaded beds and walks, thus reducing hand-trimming to a minimum. 
The “Estate 20” is built with the same care 
and precision that are characteristic of all Jacob¬ 
sen Mowers. The engine is a genuine Jacobsen 
with ample power for mowing speeds of 1J4 to 
3 miles an hour. Separate dutches for the cut¬ 
ting reel and the traction drive provide free¬ 
wheeling when both are released—a feature that 
makes for easy operation and convenience when 
storing. The cutting height is adjustable from 
li% to jbg inches, a range ample for any require¬ 
ment. This Mower has a 20-inch cutting width 
and a net weight of 183 pounds.
