3.32.3 Adjusting track width
Figure 3.80
The Rapid drill is usually supplied with the row shutoff and track width specified by the customer.
However, it is possible to change these if necessary:
! A different track width can be obtained by shifting the feed hoses to the seed coulters.
Example: A track width of 1.75 m can be increased to 2.0 m by moving the front left and rear
right one step outwards. A track width of 1.5 can be produced by moving the rear left and the fore
right one step inward (Y). For bigger changes in track width, it may be necessary to move the hos-
es inside the hopper instead.
3.32.4 Adjusting row shutoff
Figure 3.81
Tramlining can be done with 1, 2 or 3 row shutoff.
! The sowing row shutoff can be altered by exchanging the spring under the distributor head for
an operating spring (417772, 417776) or a parking spring (417795) depending on whether
more or less rows are to be shut off.
