Key features

  • Switch to transport mode quickly and easily using tow tractor hydraulics and simple hand tools.
  • Work smarter with the CT612’s large-diameter drum, which allows more oxygen to infiltrate the windrow. Also, a long tongue and adjustable hitch allow for improved visibility and easy operation.
  • Work harder with the heavy-duty frame of the CT612, featuring structural steel tubing and a steel plate for added rigidity to help prolong the life of bearings and drum shafts.
  • All grease points are accessible from ground level for ease of maintenance.
  • The aggressive Vermeer flails ensure aeration and mixing. When properly aerated, the composting cycle is considerably shortened and site throughput is increased.
  • Equipped with independently controlled lift cylinders for thorough aeration of the compost pile.
  • Rubber containment curtains draped over the front and back help keep material in the windrow, reducing the quantity and distance of thrown objects.
