by your authorized Kuhn dealer according to current
safety regulations. Always keep to the legal speed limit
for driving a tractor-machine assembly on public roads.

The rear safety device comprises:

- 2 red reflectors (1).

The front safety device comprises:

- 2 white reflectors (1).

If the machine is over the maximum legal size, follow the

local regulations for special transportation of oversize
