ATTENTION!
Do NOT operate mower while reversing. While reversing raise the cutting unit.

4.5.6 SAFETY DEVICE

The PDK220 mower is equipped with a safety device, which protects the machine against
damage resulting from collision with obstacles (FIGURE 4.14). When driving over an
obstacle, the lifting arm with the cutting unit tilts backwards (C). In such a case stop tractor
and disconnect drive and then reverse until the safety device blocks itself in setting (B).
The safety device (FIGURE 4.14) is factory set such that the length of the compressed spring
(3) is A=132 mm. If the safety device operates too frequently without cause, you may use the
nut (2) to reduce size (A) of the spring by 1 - 2 mm.
