The 400 is considerably bigger than the 200, but otherwise it works on the same principle as the 200. The 400 is a continuous composter designed for composting kitchen scraps and cut up materials from small garden.
As with the 200 (item #11549), 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 - 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 bottle of Compost Swift which you can use diluted by 8 to 1 to help get your composter going. If you like it, 32 oz bottles are available. - You are unlikely to need then but we are including 2 spare vent plugs and one spare drum cap in case you break one.
