The roller must be counter-braked when
towing. Use a towbar, because the roller
will have no ability to brake.
The roller must be towed slowly (max. 3 km/h
(5 mph)) and only a short distance (max. 300
yds).
When towing/retrieval a machine, the towing
device must be connected to both lifting holes.
Pulling forces should act longitudinally on the
machine as illustrated. Maximum gross pulling
force 80 kN (18 lbf).
