Used Concrete Mixer Truck Buying Guide: What to Check Before You Buy

This guide walks you through buying one used. You will learn how to size it, what it should cost, what to check, and how to finance it.

What Is a Concrete Mixer Truck?

A concrete mixer truck is a heavy truck with a large rotating drum mounted on the back. It hauls fresh concrete from a batch plant to a job site and keeps it mixed along the way. Most people call it a cement truck or a ready mix truck. Those names all mean the same machine.

Here is a quick note on names. “Cement truck” is the common term, but cement is only one ingredient. The truck carries concrete, which is cement mixed with sand, stone, and water. So “cement truck vs. concrete truck” is not a real difference. It is one truck with two names.

How Does a Concrete Mixer Truck Work?

The drum sits at a tilt, with spiral blades welded inside. When the drum turns one way, the blades mix the concrete. When it turns the other way, the blades push the concrete out the chute, as SANY’s guide to how concrete mixer trucks work (opens in a new tab) explains. A hydraulic pump, motor, and gearbox use the engine’s power to turn the drum. On the road, the drum keeps turning slowly so the load does not set.

Drum Truck or Volumetric Mixer?

A drum truck is not the only kind of mixer truck. A volumetric mixer carries sand, stone, cement, and water in separate bins and mixes them on site, only when you need it. A drum truck carries concrete that was already batched at a plant. That is why drum trucks rule big, steady pours, while on-site mixing suits small or remote jobs.

Why Buy a Used Concrete Mixer Truck?

A used truck lets you add a unit to the fleet without paying new-truck prices. Ready-mix fleets also replace trucks on a schedule, so a lot of good trucks reach the used market well before they are worn out. Others come back to lenders and sell with clear ownership documentation and a service record.

The risk is not buying used. The risk is buying a truck you have not checked. A mixer truck is two machines in one: an on-road truck chassis and a drum system. Both need to pass.

Step 1: Know What Size You Need

Size a concrete mixer truck by drum capacity first, then by axles. The drum tells you how much concrete it can carry. The axles tell you how much it can legally haul.

How Many Yards of Concrete Are in a Cement Truck?

Most cement trucks hold 8 to 12 cubic yards of concrete. That range comes from NRMCA’s guide to ordering ready mixed concrete (opens in a new tab). NRMCA also says that, because of weight laws, the typical truck in use today is a 9 to 11 yard unit.

Keep in mind that the drum’s rated size and the legal load are not the same number. Local weight laws and the federal bridge laws decide how much weight each axle can carry. So a truck may not be allowed to fill its drum to the top on your roads. Always size to what you can legally haul on your routes, not to the number on the drum.

Rear Discharge vs. Front Discharge

A rear-discharge truck pours from a chute at the back, so the driver backs up to the pour. It is the oldest and most common style, and it costs less to buy, according to a CONEXPO-CON/AGG guide to choosing a mixer truck (opens in a new tab).

A front-discharge truck pours from a chute over the cab. The driver drives forward to the pour and runs the mixer from inside the cab. That same guide notes this cuts one worker from the crew, since no one has to stand at the chute. Front-discharge trucks generally cost more, and they are common only in some parts of the U.S.

Axles, Weight, and State Weight Laws

Axles decide your legal payload. Most trucks run a steer axle up front, a tandem drive axle in back, and one or more lift axles. Lift axles, sometimes called pusher axles, drop down to spread the load. Some trucks also add a tag axle or booster axle behind the rear tandem. The CONEXPO-CON/AGG guide points to tag axles that spread the load for a higher legal payload.

What are the weight distribution rules for concrete mixer trucks? On the Interstate, federal limits are 20,000 pounds on a single axle, 34,000 pounds on a tandem, and 80,000 pounds gross. The federal bridge formula (opens in a new tab) also caps the weight on every group of axles based on how far apart they sit. More spread means more legal weight. Some states allow more under older “grandfather” rules, so check the law in every state you plan to run.

How Much Does a Cement Truck Weigh?

A loaded concrete truck weighs about 80,000 pounds, per NRMCA. Concrete itself weighs roughly 4,000 pounds per cubic yard. Empty weight depends on the axles, drum, and chassis. Ask the seller for a recent scale ticket so you know the real empty weight and how much legal payload is left.

How Wide Is a Cement Truck?

A cement truck is about 8.5 feet wide. Federal rules cap commercial vehicles at 102 inches wide on major truck routes, not counting mirrors and similar safety gear. That width matters on job sites. NRMCA warns that a loaded truck may not handle loose dirt or residential curbs well.

Step 2: Set Your Full Budget

How much does a cement truck cost? A used concrete mixer truck typically sells for $30,000 to $250,000. Age, miles, drum condition, and axle setup drive most of that spread.

• Older, high-mile rear-discharge trucks (15 years or older): about $30,000 to $70,000
• Mid-age trucks (7 to 15 years old): about $70,000 to $150,000
• Late-model trucks (under 7 years old): about $150,000 to $250,000 or more
• Front-discharge trucks: expect a premium over a rear-discharge truck of the same age

The price tag is only the start. Plan for these too:

• Drum and drive repairs: worn drum blades can run about $2,000 to $8,000 to fix, a hydraulic pump or motor about $3,000 to $10,000, and a drum gearbox about $6,000 to $15,000. A full drum replacement can run $25,000 to $50,000.
• A CDL driver: a mixer truck almost always needs a Class B commercial driver’s license. FMCSA defines Class B (opens in a new tab) as any single vehicle rated at 26,001 pounds or more. Mixer trucks sit well above that line.
• Insurance: commercial auto coverage for a heavy truck is a real yearly cost. Get a quote before you buy, not after.
• Registration and permits: heavier axle setups can mean higher plate fees in some states.
• Emissions upkeep: newer diesel chassis use diesel exhaust fluid (DEF) and a diesel particulate filter (DPF), and both need care.

Step 3: Inspect the Machine

Never buy a used concrete mixer truck without a hands-on inspection. If you cannot be there, hire a qualified heavy truck inspector.

Check these systems:

• Drum shell and blades: look for thin spots, patches, cracks, and hardened concrete buildup inside
• Drum drive: run the drum both ways and listen at the hydraulic pump, motor, and gearbox
• Rollers and drum ring: check for flat spots, wobble, and uneven wear where the drum rides
• Water system: tank, sight gauge, valves, and hoses
• Chute and controls: swing, lift, and lock the chute, and test every control in the cab and at the rear
• Chassis: frame, springs or air ride, brakes, tires, and every lift and booster axle
• Engine and emissions: cold start, smoke, warning lights, and DEF and DPF fault codes

If the drum will not turn smoothly under load, stop and price in a drive repair. Blade wear is a real pass or fail item. New Jersey DOT’s mixer inspection procedure will not approve a mixer with broken, missing, or badly worn blades. It counts a blade as worn out once it drops below 90 percent of its original height.

Step 4: Get the Machine’s History

The inspection tells you the machine’s current condition. The history tells you how it got there. Ask for:

• Drum hours or yards hauled: many fleets track drum hours, which show how hard the mixer side has worked
• Chassis miles and engine hours: mixer trucks idle a lot with the drum turning, so engine hours can tell you more than miles
• DOT inspection records: annual inspection reports and any repair orders that followed them
• Service records: oil, filters, hydraulic fluid, and drum gearbox service
• Emissions history: DPF cleanings, regen issues, and DEF system repairs on newer chassis
• Ownership documentation: make sure the paperwork is in the seller’s name and confirm there are no outstanding liens on the truck

Step 5: Know Your Source

Where a truck comes from matters.

Private seller

Prices can be good, but you get no inspection guarantee and little recourse.

Dealer

Often includes some warranty options, though prices tend to run higher.

Auction

Can produce deals, but you get limited time to inspect, and buyer fees add to the final price.

Online marketplace

A marketplace that connects you with multiple sellers puts more trucks in one place. PayDirt HQ is that kind of marketplace, with heavy equipment and trucks from sellers nationwide. Browse concrete mixer trucks for sale on PayDirt HQ.

Step 6: Plan Your Financing

Most buyers finance a used concrete mixer truck rather than pay cash. Financing keeps working capital free for payroll, fuel, and materials.

• Down payment: typically 10 to 25 percent of the price, depending on credit and truck age
• Loan term: most equipment loans run 24 to 72 months
• Interest rate: varies by credit score, down payment, and truck age
• Total cost: compare the total cost of the loan, not just the monthly payment

PayDirt HQ works with Equify Financial, so equipment financing options are available (opens in a new tab) when you are ready to buy. Financing is offered and underwritten by Equify Financial, which sets all rates, terms, and credit decisions. Ask about current terms when you find a machine that fits.

Mistakes to Avoid

• Buying by drum size alone. An 11-yard drum does not help if your axles only let you haul 9 yards legally.
• Ignoring state weight laws. A truck that is legal in one state may be overweight in the next. Check before you run it across state lines.
• Skipping the drum check. Thin shells, worn blades, and hard buildup inside the drum are costly to fix.
• Judging the truck by miles only. Engine hours and drum hours tell the real story on a mixer.
• Forgetting the driver. Budget for a Class B CDL driver and commercial insurance from day one.
• Not verifying ownership. Confirm the seller can sell and that no lender holds a lien on the truck.

Use this guide as your checklist. Inspect before you commit, and confirm ownership before you pay.
