    FCMP IM4000

    FCMP IM4000

    A divided barrel for alternating backyard batches

    Why it fits

    • FCMP currently lists approximately 43 US gallons total across two chambers in one rotating body, with a removable sliding door and molded handholds. The maker lists a polypropylene body, galvanized steel frame and assembled dimensions of 28 inches deep × 30 wide × 36 high. The linked pictorial requires assembly of the frame, axle, center divider and body panels. Both end caps must be oriented correctly before fitting the panels. [1] [2] [3]

    Before you choose

    • Both compartments share the rotating body; this is not two independently turning drums. The volume is total, not per chamber. [1] [2] [3]

    Check before buying:

    • Loaded turning effort and replacement-part availability are not established here.

    Maze 65-gallon Compost Tumbler

    Maze 65-gallon Compost Tumbler

    A divided drum with a geared handle and rotation lock

    Why it fits

    • Maze lists 65 gallons total, two compartments and sliding doors. Its geared handle and ratchet lock let the drum be positioned for loading or discharge. The specifications list 41.3 inches wide × 30 deep × 44.5 high, 53 lb empty weight and a zinc/powder-coated frame. Assembly is required. Maze describes an open-front stand so a bucket or compost cart can sit beneath the downward-facing door; check the receiving container against the actual clearance. [4] [5] [6]

    Before you choose

    • The divider separates batches but both compartments share the drum. A gear mechanism does not establish how much effort a full wet load requires. [4] [5] [6]

    Check before buying:

    • Exact door-opening dimensions, maintenance intervals and current US stock need confirmation; the source includes a sold-out label.

  3. #3

    FCMP HOTFROG Dual Body

    FCMP HOTFROG Dual Body

    Separate bodies rather than a divider inside one drum

    Why it fits

    • FCMP describes two separate composter bodies with removable doors and handholds, totaling approximately 37 US gallons. The listed bodies are rotationally molded polyethylene on a painted galvanized steel frame. Assembled dimensions are 28 inches deep × 30 wide × 36 high. The bodies do not need assembly, but the HF-DBC4000 booklet calls for a wrench and flat screwdriver for setup. It requires a flat site with room for rotation and describes emptying through a downward-facing door onto a tarp or into a pail. [7] [8] [9]

    Before you choose

    • Preformed bodies do not mean the entire stand arrives assembled. The 37-gallon figure is the combined volume. [7] [8] [9]

    Check before buying:

    • Individual chamber usable fill level and loaded turning effort are not measured here.

  4. #4

    Jora JK270

    Jora JK270

    Insulated steel construction with two separately accessed chambers

    Why it fits

    • Jora lists the JK270 at 70 gallons total and approximately 86 lb. Its tumbler design has two chambers with separate doors and turns by hand on a central axle. Jora describes galvanized steel panels and insulation around the chambers. The assembled footprint is not confirmed from the manufacturer sources used here. Jora provides JK270 assembly instructions that recommend two people, with assembly of the stand and insulated panels. Its setup page directs buyers to support the finished stand on concrete, slabs or planks rather than soft soil. [10] [11] [12]

    Before you choose

    • Insulation is a construction feature, not a measured compost-temperature or winter-throughput result. Account for the empty weight and firm support before choosing its location. [10] [11] [12]

    Check before buying:

    • Assembled dimensions, loaded turning force, door-opening dimensions and hardware maintenance intervals need confirmation.

  5. #5

    FCMP IM2000

    FCMP IM2000

    A smaller elevated single-batch barrel

    Why it fits

    • FCMP lists approximately 22 US gallons in one chamber, with a removable door and molded handholds for turning. The maker specifies a polypropylene body, galvanized steel frame and assembled dimensions of 19 inches deep × 24 wide × 30 high. The maker’s pictorial shows assembly of the frame, axle, end caps and panels. The door frame fits only the designated end-cap lip; confirm panel orientation before fastening. [13] [14] [15]

    Before you choose

    • It has no second chamber for a separate batch. Choose the smaller volume for a limited batch rather than assuming it can absorb an entire yard’s clippings. [13] [14] [15]

    Check before buying:

    • Door-opening dimensions, replacement parts and loaded turning effort need confirmation.

    Mantis Compact ComposTumbler

    Mantis Compact ComposTumbler

    A large single drum turned with a geared crank

    Why it fits

    • Mantis lists an 88-gallon single drum, a gear-driven handle and a removable twin-latch door. Mixing fins are described inside the drum. The individual specifications list a powder-coated galvannealed steel drum, plastic end caps and tubular steel frame. That table gives 33 × 42 × 43 inches L×W×H, but the same page’s comparison table gives 26 × 31 × 37; confirm the footprint before buying. The maker describes ventilation and drainage openings. Confirm the current assembly and care instructions before ordering; this comparison does not establish the assembly workload. [16] [17] [18]

    Before you choose

    • There is one batch compartment, despite the large volume. Conflicting footprint tables prevent a firm recommendation for a tightly sized space. [16] [17] [18]

    Check before buying:

    • Empty weight, exact hatch size and the current assembly and care instructions need confirmation.

  7. #7

    Mantis Back Porch ComposTumbler

    Mantis Back Porch ComposTumbler

    A single drum with two transport wheels

    Why it fits

    • Mantis lists a 37-gallon single drum, molded finger grips for rotation and a removable loading door. The individual specifications list a double-wall HDPE drum with an air cell, powder-coated steel tubing and two wheels. Its 26 × 31 × 37-inch L×W×H table conflicts with the comparison table’s 33 × 42 × 43; confirm the delivered footprint. The maker describes tipping the frame back to use the transport wheels and includes vents and drainage openings. The wheels are for moving the unit, not a crank for rotating its drum. [19] [20] [21]

    Before you choose

    • The page also calls it metal in generic prose, contrary to its HDPE drum specification. Confirm CT08002 materials and dimensions with the seller; loaded mobility is untested. [19] [20] [21]

    Check before buying:

    • Empty weight, assembly workload, exact door size and care schedule are not established here.

    Good Ideas Compost Wizard Dueling Tumbler

    Good Ideas Compost Wizard Dueling Tumbler

    Two batches in a low bin supplied with a roller base

    Why it fits

    • Good Ideas describes two separated 25-gallon chambers and 8-inch twist lids. The included base has wheels and collects liquid draining from the bin. The maker lists recycled plastic construction, dimensions of 30 inches deep × 22 wide × 25 high and 28 lb product weight. The listing says the unit comes fully assembled, with the bin, collecting base, plug and trilingual instructions included. [22] [23] [24]

    Before you choose

    • The low position and 8-inch lids are different loading choices from a raised barrel with a broad hatch. The liquid collector is a component description, not advice about applying its contents. [22] [23] [24]

    Check before buying:

    • Roller turning force, collector cleaning procedure and measured loaded access are not established here.

    Lifetime Double Bin Rotating Composter

    Lifetime Double Bin Rotating Composter

    Two 50-gallon tumblers with loading locks

    Why it fits

    • Lifetime describes two 50-gallon tumblers, totaling 100 gallons, with internal aeration bars, textured grip handles and spring-loaded rotation locks for filling. The product page lists double-wall HDPE panels, a powder-coated steel frame and large removable lids. Its specifications section does not establish a usable assembled footprint in this readback. The 60309 manual requires two capable adults for assembly on a level surface. Its care section recommends mild soap and a soft brush and discourages abrasive cleaners on the plastic. [25] [26] [27]

    Before you choose

    • Confirm assembled width and drum rotation clearance before buying. The combined 100-gallon figure does not describe the volume of either individual barrel. [25] [26] [27]

    Check before buying:

    • Assembled dimensions, empty weight and loaded turning force are unconfirmed in the sources used here.

    FCMP Half Size Rolling Composter

    FCMP Half Size Rolling Composter

    A small single bin that can roll directly across the yard

    Why it fits

    • FCMP lists 19 US gallons in its half-size rolling bin, with a sliding removable door and molded handholds. The RC2000WB booklet identifies the model. The maker lists polyethylene construction and dimensions of 24 inches deep × 12 wide × 24 high. The product page says no assembly is needed and describes rolling the bin to the garden to unload. Its booklet calls for a flat site with rotation room and moisture checks. [28] [29] [30]

    Before you choose

    • It has a single small batch compartment. Rolling the bin to unload is a different workflow from emptying a barrel on a raised stand; ease across uneven ground is untested. [28] [29] [30]

    Check before buying:

    • Full-load rolling effort, door-opening size and replacement parts are not established here.

Separate total capacity from batch layout

IM4000 and Maze divide one rotating body into two chambers. HOTFROG uses two bodies, while Lifetime lists two 50-gallon tumblers. IM2000, the Mantis Compact and Back Porch, and the half-size rolling FCMP are single-batch designs. Choose the layout as well as the total container volume. [1] [4] [7] [25] [13] [16] [19] [28]

Check how you will load, turn and empty it

Maze and Mantis Compact use geared handles; IM2000 uses molded handholds. Good Ideas has 8-inch twist lids and a low collecting base; HOTFROG’s instructions describe emptying a downward-facing door. Compare the access arrangement with the tools or receiving container you intend to use. None of these mechanism descriptions establishes measured full-load turning effort. [4] [16] [13] [22] [9]

Reserve space and plan setup before ordering

Leave rotation and loading access beyond the listed assembled dimensions. Mantis’s individual and comparison tables disagree, and Lifetime’s footprint is unconfirmed here. Jora calls for firm support rather than soft ground. FCMP’s half-size rolling unit and Good Ideas’ Dueling Tumbler are listed as requiring no assembly or fully assembled, respectively; Lifetime’s manual requires two capable adults. Read model-specific care instructions before use; the Lifetime manual specifies mild soap and a soft brush for plastic. [17] [20] [26] [12] [30] [24] [27]

How we compared.

Source-based research from manufacturer pages, model-specific instructions read October 3, 2026. No hands-on composting, turning-force, odor, pest-exclusion or durability tests. Ranked order starts with divided backyard tumblers, then independent bodies and insulated construction, followed by smaller or specialized single-batch and large-bin layouts. Capacity is maker-stated container volume, not weekly throughput or finished-compost yield. An owner identified as J. in a review displayed on the Mantis Compact page described a two-person assembly; that anecdote prompted an assembly check, not owner consensus or a verified requirement. Colour variants and cart bundles are not extra picks. Conflicting dimensions and unconfirmed maintenance details are flagged; use the instructions supplied with the exact unit.
