locked with spring pints. See figure 1. A damper spring is mounted between the arm and the
machine end. See figure 3 (used in some models). For further information on function and

Mounting to the tractor
When delivered the crossbar of the drill is mounted to the drawbar in its place. Because the
crossbar of the drill is attached with a quick coupling the simpliest way to mount it is to fasten it
first to the lower links of the tractor and then connect it to the machine. See figure 2.
The crossbar is detached from the machine by lifting it slightly in the notches, by pulling the
releasing rope and by lowering the crossbar. See figure 4. The crossbar can be used in links of
categories II and III. See fig. 2. Use only ring pins of high quality to lock the crossbar to the links.
After having fastened the crossbar to the lower links of the tractor, reverse the tractor to the front of
the drill so that the crossbar lies precisely under the drawbar. When the crossbar is lifted it is
locked to the drawbar. Figure 5.
