THE APPLE 



Sulky plows. Sulky plows — walking, riding, landside, and rever- 

 sible — are being used wherever orchard conditions permit. They 

 may be used in the method of plowing just described, or in plow- 

 ing toward one row of trees and leaving a dead furrow at the 

 next row, which is on the other side of the cultivated strip, the 

 next year reversing the plowing. 



Gang plows. Gang plows have been used in many large or- 

 chards to economize time. The size varies from 2 to 6 or more 



Fig. 51. A good type of orchard tractor harrowing 



plows to each gang, the increase in size being due to the intro- 

 duction of tractors as the propelling power. Generally these gangs 

 are used between the rows of trees, the furrows being turned in 

 one direction, thus leaving a furrow toward the row of trees at 

 the left and a dead furrow toward the row of trees at the right, 

 or vice versa. The advantages of the tractor-gang plowing are 

 a saving of time, more uniform work, and less expense. 



A few orchardists have used the disk plow and found that 

 where the land is fairly free from stone it is very satisfactory. 

 These plows may be used in any of the methods of plowing given 

 above, their great advantage being that they leave the turned soil 

 in a more broken condition, thereby aiding the work* of fining.
