TOWNSEND'S TRIPLEX 



The Greatest 

 Grass-cutter 

 on Earth 



Cuts 



Swath 



86 Inches Wide 



Floats Over the Uneven Ground 

 as a Ship Rides the Waves 



One mower may be climbing- a knoll, the second 

 skimming- a level, while the third pares a hollow. 

 Drawn by one horse and operated by one man, 

 the TRIPLEX will mow more lawn in a day 

 than the best motor mower ever made; cut it 

 better and at a fraction of the cost. 



Drawn by one horse and operated by one man, it will mow more 

 lawn in a day than any three ordinary horse-drawn mowers with 

 three horses and three men. 



Does not smash the gTass to earth and plaster it in the mud in 

 springtime, neither does it crush the life out of the grass between 

 hot rollers and hard, hot ground in summer, as does the motor 

 mower. 



The public is warned not to purchase mowers infringing the 

 Townsend Patent, No. 1,209.519, December 19th, 1916. 



Write for catalog illustrating all types of Lawn Mowers.
