3.9.1 ADJUSTMENT OF THE ROLLER
To ensure the perfect parallelism of the machine at work it is ne -
cessary to set the working depth on rear rollers, and for doing this
you just have to act on the hydraulic cylinder (A Fig.22) or on the
mechanical tie-rod (Fig. 22B).
The maximum depth of the equipment is 10 cm.
ATTENTION
Read and observe the general safety ragulations!
In order to adjust the working depth lift the harrow from ground
level only with a few centimeters!
Pay very much attention in the area of the rolls and of the
operating disks.
The back roll, besides adjusting the work depth, also performs a
uniformization of the worked land.
ATTENTION
- Read and observe the general safety ragulations.
- Only make such adjustments with the disc harrow fully re-
sting on the ground!
In the event of mounting the ring roller, the position of the
fixing screws must be as shown in Fig. 23.
