Easy hitch of your trailer
The ROLL-LINK system invented by Rolland allows facilitating the hitch of the auto-steer cylinders of a Rollspeed, Rollroc, Rollmax or Ampliroll. The steer axle is permanently piloted by an embedded hydraulic circuit, with 1 or 2 cylinders placed on the drawbar and linked to the tractor via ROLL-LINK.
The hydraulic circuit is closed and contains 1 or 2 nitrogen balls to maintain the pressure and absorb chocs.
This system can also be used as a free steering axle if the tractor in front is not prepared for ROLL-LINK. (Except Ampliroll range)
