We ship these mixers every week, and the sizing conversation is nearly always the same. A crew pouring footings and fence posts orders the 500L drum because bigger feels safer, then hauls an oversized machine through a wet yard for jobs that would finish in two batches. The machine mixes and places concrete on site without a separate truck, and it pays for itself once you are pouring more than a few cubic metres a month. Under that, a ready-mix truck or a hired mixer is the cheaper route.

Four things decide which model leaves the factory with your name on it: drum capacity, engine power, discharge mechanism and tracked mobility. We match each of them to the job patterns we see in real orders, so you buy the right size the first time instead of the biggest machine on the lot.

What to look for in a small tracked concrete mixer

The four specs, in the order they matter. Drum capacity sets the batch size per pour. Engine power keeps the drum turning with a full load of wet mix. Discharge mechanism decides how the concrete leaves the drum and how precisely you can place it. Tracked mobility decides whether the machine reaches the pour point at all. Get those right and the mixer is a one-man tool. Get the size wrong and you either pour too-small batches all day or fight an oversized drum through mud.

Drum capacity: 200L, 360L or 500L?

Size the drum by your average pour volume per job, not the biggest pour you can imagine. A crew that pours footings and fence posts in 200L batches burns time and fuel dragging a 500L drum to every small job, and pays more for the machine in the first place.

Model Drum Engine Best for
SDL200L 200L R21 7.5HP gasoline Footings, fence posts, small slabs
SDL360L 360L R500 19.5HP gasoline Foundations, driveways, patios
SDL500L 500L R420 15HP gasoline, hydraulic discharge Continuous work, larger sites

Here is the rule we give buyers. If most pours fit in one or two batches, take the smaller drum. It mixes faster per batch, moves more easily and ties up less capital. Step up a size only when you regularly pour more than that drum handles in a sensible number of batches.

Factory specs for all three sizes are published before you order: the SDL200L 200L tracked concrete mixer, the SDL360L 360L tracked concrete mixer and the SDL500L 500L tracked concrete mixer with hydraulic discharge.

Engine: match power to how you run

Gasoline engines are standard on small tracked mixers because they weigh less and start easier than diesel. The SDL200L uses an R21 7.5HP unit, the SDL360L a 19.5HP R500, and the SDL500L an R420 15HP gasoline engine. What no spec sheet tells you is drum-laden performance. The engine has to hold the drum rotating steadily with a full load of wet mix on a slight incline, which is a different test from running empty on flat concrete. Ask how the machine pulls with a full drum, not how it sounds empty.

Long continuous shifts change the fuel arithmetic. Diesel-drive options are available on request, and they are worth a conversation if you pour daily rather than two or three times a week.

Why tracked mobility earns its keep

A tracked undercarriage crosses soft ground, mud and gravel without sinking. On an active site the pour point is rarely where the truck can park, and that gap is exactly what the tracks are for. Rubber tracks also leave finished floors and landscaping alone, so the machine can travel from a finished slab to the next form without marking either one. Every TorqMax concrete mixer ships with rubber tracks as standard.

If your work is all hard-standing yards, wheels would be lighter. The moment mud or a finished floor enters the picture, tracks decide whether you drive the mixer to the concrete or carry the concrete to the mixer.

Discharge: manual tip vs hydraulic drum discharge

Manual tipping is slower, less precise, and it forces the operator to reposition the whole machine for every dump. Hydraulic drum discharge is standard on the SDL500L, and it lets one man pour exactly where the concrete is needed from a standing position, inching the drum over the form and controlling the flow. Crews that switch usually drop one person from the pour team, because nobody is shovelling from a tipped drum into a wheelbarrow any more.

If you pour slabs, footings, or anything where placement accuracy matters, budget for hydraulic discharge. We see it pay back on the first week of pours.

Mix on-site or order ready-mix?

Every small contractor weighs this one. Ready-mix makes sense for big single pours where the truck reaches the form and the volume clears the delivery minimum. A tracked mixer wins on remote or tight sites, on several small pours in one day, on custom mixes, and on any job where a ready-mix truck cannot physically get close enough to place concrete without a pump.

Most of our customers run both. Order ready-mix for the slab, use the mixer for footings, patches and the jobs in between. If you turn away small pours today because the delivery minimum kills the margin, that lost work is what the mixer pays for.

Cost of ownership beyond the purchase price

  • Drum cleaning. A few minutes with water at the end of every pour protects the drum. Hardened concrete inside a drum is the most common way small mixers die.
  • Wear parts. Drum blades and track sections are the consumables, so budget a set with the first order.
  • Engine service. Oil, air filter, plug. Keep it periodic and a gasoline engine still starts first pull two years in.
  • Fuel. Gasoline is economical for intermittent pours. Daily use shifts the arithmetic toward diesel on request.

Buying factory-direct keeps wear parts coming from the same plant that built the machine, and the export file (invoice, packing list, certifications) is prepared for your destination market. Our wholesale, OEM and ODM guide walks through the full process.

Decision checklist before you order

  • Average pour volume per job calculated, rather than the biggest pour you can picture?
  • Drum size chosen by batch count, 200, 360 or 500L?
  • Engine confirmed holding a full wet load on your typical site?
  • Tracks needed for mud, soft ground or finished floors?
  • Hydraulic discharge selected where placement accuracy matters?
  • Drum-cleaning time and a spares kit in the budget?

Get all six and you can place the order without second-guessing the size.

Frequently asked questions

What size concrete mixer do I need?

Match the drum to your average pour, not your biggest one. 200L suits footings and small slabs, 360L covers foundations and driveways, and 500L is for continuous work on larger sites. If most of your pours fit in one or two batches, the smaller drum will finish them faster. Sizing up costs money and slows the small jobs down.

Can a tracked mixer move across mud?

Yes, and that is the main reason to pay for tracks. Rubber tracks are built for soft ground, gravel and finished floors, and they spread the weight of the machine instead of sinking it. You drive to the pour point rather than barrowing concrete across the site. Every TorqMax mixer we ship has them as standard.

Is hydraulic discharge worth it?

If placement accuracy matters, or you pour often, yes. Hydraulic discharge, standard on the SDL500L, lets one operator pour precisely from a standing position and usually removes one person from the pour team. On occasional footing work with plenty of room to manoeuvre, manual tipping still does the job for less money.

Gasoline or diesel?

Gasoline is the standard choice on small tracked mixers and the simpler one to live with: lighter, easier to start, and cheap to run for pours spread across the week. Diesel-drive options are available on request and suit crews running continuous daily shifts, where fuel cost compounds over months of pouring.

Do you ship spare parts with the mixer?

Yes. Drum blades, track sections and engine consumables such as oil, filters and plugs can ship with the order from the same factory that built the machine. We recommend putting a set in the first order. Waiting for a single part to clear customs costs more in lost pouring days than the part costs.

Can one person operate a tracked concrete mixer?

Yes. The drum, engine controls and hydraulic discharge are laid out for single-operator use. With hydraulic discharge one man pours directly from a standing position, which removes the second worker who would otherwise shovel from a tipped drum into a barrow. A two-man crew can therefore cover more pours in a day.
