Key features

  • Conveniently stay in control from the comfort of the tow vehicle by utilizing the cabled remote controller. Changes can be made on the fly as the unit goes through the windrow.
  • Simply adapt to site conditions with the height setting indicators to help monitor height while from the tow vehicle.
  • Process material more efficiently with the large drum size.
  • The slow speed transport kit allows the CT616 to be hauled from site-to-site, making it a more mobile machine.
  • Enhance operator safety with automatic drum shutdown.
  • The aggressive Vermeer flails help ensure aeration and mixing. When properly aerated, the composting cycle is considerably shortened and site throughput is increased.
  • Engine power is transferred through the hydraulically actuated PT Tech clutch. To help extend clutch life, control software prevents the operator from engaging or disengaging the drum drive at full engine rpm.
  • All grease points are accessible from ground level. Hinged, lockable doors on both sides of the engine provide spacious access for maintenance.
