6.11. Adjusting the rear harrow

Figure. 6.11. - 137. Adjusting the rear harrow 

1.  Use the bolt (1) to adjust the height of the rear harrow.

The  longer  the  visible  portion  of  the  bolt,  the  higher  the  position  of  the  rear

harrow. 

2.  Adjust the angle of the rear harrow by inserting the rear harrow pin (2) in the appropriate

hole (3). 

There are three holes to choose from.

When the pin is in the bottom hole, the rear harrow is in an upright position. This

position enables the rear harrow to move the most soil. 

When  the  pin  is  in  the  top  hole,  the  angle  of  the  rear  harrow  position  is  the

widest. This position is used if there is a lot of mass on the ground. This position

enables the rear harrow to penetrate the ground best.
