The Sun-Mar Garden Composter 400 is the larger, heavy-duty model in the Sun-Mar garden composter lineup — engineered for durability, designed to handle consistent use in harsh outdoor environments, and built around Sun-Mar's proprietary Autoflow® technology for faster, more efficient composting results. Yard waste and kitchen scraps load easily through a sliding door, a crank handle makes aeration effortless, and as material finishes composting, it moves automatically through the output door without digging or manual extraction. At nearly double the capacity of the Garden Composter 200, the 400 is the right choice for households with a larger yard, a bigger garden, or more organic waste to process.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutoflow® Technology\u003c\/strong\u003e — Sun-Mar's proprietary Autoflow® system accelerates the composting process and allows finished compost to be removed automatically from the output door as new material is added and processed — no manual extraction required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeavy-Duty Construction for Harsh Environments\u003c\/strong\u003e — Built with durability in mind, the Garden Composter 400 is manufactured to withstand harsh outdoor conditions and consistent, long-term use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e366-Liter Drum Capacity\u003c\/strong\u003e — Approximately 11 bushels or 100 gallons of composting volume — nearly double the capacity of the Garden Composter 200 — making it well suited for households with regular yard waste and kitchen scraps.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSliding Input Door for Easy Loading\u003c\/strong\u003e — Yard waste and kitchen scraps are loaded quickly and cleanly through a sliding door on the drum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrank Handle Aeration\u003c\/strong\u003e — A built-in crank handle makes rotating and aerating the compost simple and low-effort, even with a full drum.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Compost Output\u003c\/strong\u003e — As material finishes composting, it can be removed automatically from the output door — no digging, scooping, or manual removal required.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNo Electricity Required\u003c\/strong\u003e — The Garden Composter 400 operates entirely without power.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eGarden Composter 400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eGC40-00002\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDrum Volume\u003c\/td\u003e\n\u003ctd\u003e366 liters (approx. 11 bushels \/ 100 gallons)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight\u003c\/td\u003e\n\u003ctd\u003e29\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth\u003c\/td\u003e\n\u003ctd\u003e29\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e46\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Weight\u003c\/td\u003e\n\u003ctd\u003e85 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAeration Method\u003c\/td\u003e\n\u003ctd\u003eCrank handle rotation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Method\u003c\/td\u003e\n\u003ctd\u003eSliding input door\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Method\u003c\/td\u003e\n\u003ctd\u003eAutomatic — Autoflow® technology\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTechnology\u003c\/td\u003e\n\u003ctd\u003eAutoflow®\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eElectricity Required\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrice\u003c\/td\u003e\n\u003ctd\u003e$489.00 USD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailability\u003c\/td\u003e\n\u003ctd\u003eCurrently sold out — confirm restocking with Sun-Mar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping\u003c\/td\u003e\n\u003ctd\u003eContact Sun-Mar sales at 1-888-341-0782 (option 1) for more information\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eNot available on page — please provide.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003eNot available on page — please provide.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Carton Dimensions\u003c\/td\u003e\n\u003ctd\u003eNot available on page — please provide.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eFAQs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What makes the Garden Composter 400 different from the Garden Composter 200?\u003c\/strong\u003e A: The Garden Composter 400 has nearly double the drum capacity of the 200 — 366 liters (approx. 100 gallons) versus 195 liters (approx. 50 gallons). It also features Sun-Mar's Autoflow® technology, which allows finished compost to be removed automatically from the output door, and uses a crank handle for aeration rather than finger-slot drum rotation. The 400 is designed for heavier, more consistent use and harsher outdoor environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How does Autoflow® technology work?\u003c\/strong\u003e A: Sun-Mar's Autoflow® technology is built into the drum design of the Garden Composter 400. As material is composted and new material is added, finished compost moves automatically through the drum and can be removed from the output door without manual digging or scooping.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do I add material to the Garden Composter 400?\u003c\/strong\u003e A: Yard waste and kitchen scraps are loaded through a sliding door on the drum. No special preparation is required beyond cutting up larger garden trimmings for faster composting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does the Garden Composter 400 require electricity?\u003c\/strong\u003e A: No. The Garden Composter 400 operates entirely without power.\u003c\/p\u003e","brand":"Sun-Mar","offers":[{"title":"Default Title","offer_id":47901451845850,"sku":"GC40-00002","price":489.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0704\/5283\/8618\/files\/SunMar_52.png?v=1779329607","url":"https:\/\/powergenstore.com\/products\/sun-mar-garden-composter-400-large-capacity-rotating-drum-composter-with-autoflow%c2%ae-technology-gc40-00002","provider":"PowerGen Store","version":"1.0","type":"link"}
