TRANSPORTING
TRANSPORT LOCK VALVES
(Figs. 40, 41 & 42)
When the Disc Mower Conditioner is going to be
transported on a public highway, BE SURE to raise the
unit all the way up and actuate both lift system transport
lock valves. Also, BE SURE to swing the drawbar to the 1
centered transport position with the hydraulic hitch
positioner and position the transport lock valve on the
drawbar in the transport (“closed”) position.

On units not equipped with the 2-point hitch, the Disc
Mower Conditioner can be equipped with a safety chain
for operation on public highways. A sturdy chain loop
is welded to the side of the drawbar to facilitate
anchoring the chain. The safety chain, when attached in
this manner, has the following characteristics:
1. Chain is sufficiently slack to allow turns and
