B6501      Anti - Clockwise Rotation

B6504     Clockwise Rotation (2 views)
  • Patented Heavy Duty Cushion Coupling providing limited predetermined rotational travel whilst carrying a MASSIVE 5000 NM (3688 ft/lbs) of Torque.
  • Danish Super Valve Spring Quality drive springs combined with 1 piece heat treated Drive and Driven Plates provide ultimate reliability.
  • Designed for LARGE Multihead Cutters with Timed Blades which preclude the use of safety slip clutches.
  • Without the Bare-Co® Heavy Duty Cushion Coupling, these machines can suffer outer gearbox coupling & shaft failures due to the flywheel effect of associated cutter disks being combined with tractor PTO torque.
