PLEASE NOTE: The special pricing on these composters applies to stock on hand only. Thank you.

Turn your kitchen and garden waste into nutrient-rich compost faster than traditional composting methods. The patented double drum Autoflow® design directs material along the outer drum and then back through the inner drum and to the output port. Just slide open the door, add your material, and turn the drum to mix and aerate. By the time compost reaches the output port, it has become a light, fluffy end product. Unlike other composters that require you to stop adding material at some point, the Sun-Mar 400 can be loaded continuously for a steady stream of rich compost for your garden. Includes optional rollers, which can be snapped into the cradle base to make it easier to move the unit when it is on a hard surface.

Sun-Mar 400 Features

  • Compost material can be added continuously - no waiting for a batch to be finished
  • Compost discharges automatically when the output port is open
  • Dual drum design is pest resistant
  • Easy loading and tumbling
  • Includes a sample bottle of Compost Swift which you can dilute and use to help get your compost going

How to Compost with the Sun-Mar 400 Garden Composter

  • Add material by sliding the input door open
  • Mix and aerate the compost by turning the handle shaft
  • Remove compost by opening the output port and rotating the drum
