Buffalo Pitts Spring Fiexiliie Disc Harrow 



WITH SPRING ACTION ON THE DISC QANOS. 



The only Disc Harrow made having a spring pressure device, which alone places it far in advance of 

 any competitor. The greatest objection to all other disc harrows is the "humping-up'" in the center, caus- 

 ing the outer discs to run deeper than the center ones with consequent uneven depth of work. This is all 

 overcome on the Pitts by a pair of flexible steel springs running from the pole to the main axle, controlled 

 by foot of driver.
