Compare portable drum mixers and towable concrete mixers to find the right rental for your job site.
Choosing between a drum mixer and a towable concrete mixer comes down to your project's scale, site access, and how much concrete you need to move. Both are available to rent locally through Rntr, so you can match the right equipment to your job without paying for a machine that's too big or too small. This guide breaks down the real differences between the two types so you can make a confident decision before you book.
Common Questions About Concrete Mixer Types
- Which type of concrete mixer is best?
- The best concrete mixer depends on the volume of concrete your project requires and how portable the equipment needs to be. For small to medium jobs like footings, fence posts, or a backyard pad, a portable drum mixer in the 3 to 6 cubic foot range handles the work efficiently and is easy to position on a residential site. For larger pours, driveways, or commercial flatwork where you need to move significant volume quickly, a towable concrete mixer with 9 cubic feet or more of capacity saves time and reduces the number of batches you need to mix. Renting means you can right-size the equipment to each job rather than being locked into one machine.
- What is the 4-2-1 rule for concrete?
- The 4-2-1 rule is a basic mix ratio guideline: 4 parts aggregate (gravel), 2 parts sand, and 1 part cement by volume. This general-purpose ratio produces a workable mix suitable for most residential concrete work, including slabs, footings, and pathways. Water is added gradually until the mix reaches the right consistency, typically a slump that holds its shape without being soupy. Both drum mixers and towable mixers can produce a proper 4-2-1 mix; the key difference is how much you can batch at once.
- What is the difference between a drum mixer and a volumetric mixer?
- A drum mixer blends a pre-measured batch of dry materials and water in a rotating drum. You load the ingredients, let it mix, pour the batch, and then reload for the next one. A volumetric mixer is a larger, truck-mounted system that stores sand, aggregate, cement, and water in separate compartments and continuously meters and mixes fresh concrete on demand. Volumetric mixers are used for large commercial pours and are not typically available through a local equipment rental shop. For most residential and small commercial projects, a drum mixer or towable drum mixer is the practical and cost-effective choice.
- What is called a drum type concrete mixer?
- A drum type concrete mixer is any mixer that uses a rotating cylindrical drum to tumble and blend concrete ingredients. The drum spins on an axis, and internal fins or blades lift and fold the materials as it rotates, producing a consistent mix. This category includes both stationary electric drum mixers used on smaller jobs and larger towable drum mixers pulled behind a pickup truck to the job site. Most rental concrete mixers you'll find at local equipment shops fall into the drum mixer category.
Understanding the Two Types of Concrete Mixers
Before comparing specifications and rental rates, it helps to understand what separates these two categories of concrete mixing equipment at a fundamental level.
Drum mixers (also called portable concrete mixers or cement mixers) are compact, self-contained units that sit on a frame with wheels or a stand. They are typically electric or gas-powered and range from 2.5 cubic feet on the small end up to around 6 or 7 cubic feet for the larger models available at most rental centers. You can roll them into position by hand, plug them in, and start mixing. They are the go-to choice for homeowners, landscapers, and small contractors doing targeted concrete work on residential sites. A 3 cubic foot electric concrete mixer is a common starting point for fence post work or a small footing project.
Towable concrete mixers are trailer-mounted drum mixers that hitch to a pickup truck or SUV and are pulled directly to the job site. Their drums are significantly larger, typically in the 9 cubic foot range, and they are almost always gas-powered to function independently of an electrical connection. A 9 cubic foot towable gasoline concrete mixer gives you roughly three times the batch capacity of a standard portable drum mixer, which makes a significant difference when you are pouring a driveway section or a larger slab.
Both types use the rotating drum mixing method, so the quality of the mix is comparable when loaded correctly. The primary difference is scale, mobility, and power source.

Drum Mixer: What It Does Best
A portable drum mixer is the right tool when your project involves manageable batch sizes and site conditions that favor compact equipment.
Here is where a drum mixer excels:
Here is where a drum mixer excels:
- Fence post footings and anchor bases: Small batch requirements make a 2.5 or 3 cubic foot mixer perfectly adequate, and you can move it by hand from post to post.
- Residential repair work: Steps, small pads, garden borders, and structural repairs typically need limited volume. Overpaying for a large towable mixer makes no sense for these jobs.
- Tight access areas: Narrow gates, backyard access paths, and constrained job sites where a trailer cannot be positioned or parked make a compact drum mixer the only practical option.
- Indoor or covered work: Electric drum mixers can be used in garages or under covered structures safely, unlike gas-powered towable units that require outdoor operation.
- Short rental windows: If you only need concrete for a few hours of work, a smaller mixer rented for a single day keeps your rental cost low.
Portable drum mixers typically rent for $40 to $75 per day depending on size and power source. Electric models in the 2.5 to 3 cubic foot range sit at the lower end of that range, while 6 to 7 cubic foot gas drum mixers are priced higher. If you are doing similar work but on a larger residential project, consider something in the middle range, like a 6 cubic foot gas-powered concrete mixer, which bridges the gap between compact drum mixers and full towable units.
Towable Concrete Mixer: What It Does Best
A towable concrete mixer earns its higher rental rate on projects where volume, speed, and site mobility all matter. If you need to mix multiple yards of concrete over the course of a day and move the equipment between points on a job site, a towable mixer gives you a meaningful productivity advantage.
Driveways and large slabs: Pouring a full driveway or a large patio slab requires consistent production. A 9 cubic foot drum lets you run larger batches and keep pace with your pour.
Multiple footings on a spread-out site: Pulling a towable mixer from location to location on a large lot or commercial site is far more practical than hand-carrying a portable mixer.
Construction sites without reliable power: Towable mixers are gas-powered, so they operate anywhere your truck can go. No extension cords, no worrying about outlet access.
Small contractor applications: For crews doing flatwork, decorative concrete, or block laying across multiple jobs in a day, a towable unit handles the workload that a portable drum mixer cannot sustain.
Towable concrete mixers typically rent for $90 to $150 per day or $300 to $500 per week, depending on the rental provider and your location. Weekly rates can offer solid value if your project is likely to stretch across several days. Most rental providers require a hitch on your vehicle and may ask for a deposit. Confirm the trailer hitch requirements with your local provider before booking, since some towable units require a standard 2-inch ball hitch.
For related guidance on choosing the right construction equipment for a specific job, the comparison between walk-behind vs. ride-on trenchers follows a similar logic: the right choice is always the machine sized to match your project's actual demands.

How to Choose the Right Mixer for Your Project
Several practical factors help narrow down the right rental choice between a drum concrete mixer and a towable concrete mixer.
Estimate your concrete volume first. A cubic yard of concrete equals 27 cubic feet. If your project requires half a yard or less, a portable 5 or 6 cubic foot drum mixer handles the job without difficulty. If you are approaching a full yard or more, a towable unit with a 9 cubic foot drum cuts your batch count significantly and keeps the pour moving at a productive pace.
Consider your site layout. Homeowners frequently discuss this on forums: a towable mixer requires a truck, a trailer hitch, and enough clearance to park and operate the trailer near the work area. If your job site has a locked gate, narrow path, or no way to maneuver a trailer, a portable drum mixer is the only viable option regardless of volume.
Check your power access. If you are working in a backyard or on a remote site without easy access to a 120V outlet, a gas-powered unit, either a gas drum mixer or a towable model, is the cleaner solution. Electric drum mixers are quieter and lower-maintenance, but they do require a reliable power source within practical extension cord range.
Factor in your timeline. Mixing concrete in small batches with a portable unit takes more total time than running the same volume through a larger drum. If you have a crew waiting on concrete and a deadline for your pour, the productivity boost of a towable mixer often justifies the higher daily rental rate. If you are working solo over a relaxed weekend project, a smaller drum mixer at a lower daily cost makes more sense.
