Sun-Mar 100 Gallon Garden Composter


  • 366 liter/100 gallon composter
  • Rotates easily to mix/aerate compost
  • Included sample of Compost Swift compost accelerator


SUN-MAR 400 is ideal for kitchen Scraps and cut up materials from a small garden.

As with the 200, material is added to the 400 by sliding the input door open.

To mix and aerate the compost, the 400 drum is rotated by turning a shaft on which a small gear bears directly against the gear teeth on the drum.

Compost is removed by opening the output port, rotating the drum and allowing compost to fall from the inner drum into a bushel basket or other container.

Included with the SUN-MAR 400:

Optional Rollers; the unit has 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.

Sample Compost Swift; the 400 has a sample bottle of Compost Swift which you can use diluted by 8 to 1 to help get your composter going. If you like it, there is a large 32 oz bottle available.

Spare Parts; you are unlikely to need then but included are 2 spare vent plugs and one spare drum cap in case you break one.
