Buffalo Pitts Spring Flexible Disc Harrow, 



WITH SPRING ACTION ON THE DISC GANGS. 



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 

 centre, causing the outer discs to run deeper than the centre 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.
