The SDL500L is a 500L tracked concrete mixer with a 15HP gasoline engine and rubber crawler chassis — the practical answer for moving real volumes of concrete across mud, gravel and soft ground where a wheelbarrow quits. These two videos show it working on actual job sites, not in a showroom.

If you are laying paths, setting foundations for sheds and greenhouses, or pouring fence posts on village roads, the SDL500L mixes on site and drives itself to the pour — no second machine, no extra crew, no waiting for a truck mixer.

Watch it work

What makes the SDL500L different

  • 500L drum capacity — roughly two and a half times a 200L machine. One batch is enough for a solid fence run or a small slab, which means fewer refills and less walking.
  • 15HP R420 gasoline engine — generous power reserve for heavy mixes, kept in the same compact footprint.
  • Rubber crawler tracks — the machine crosses mud, sand, gravel and soft topsoil without sinking; it also climbs reasonably steep access ramps, as the videos show.
  • Self-propelled — the operator walks alongside instead of pushing a loaded barrow, so fatigue is not a production limit.
  • Steel frame chassis — built for daily site abuse, with export powder-coating to survive sea freight and humid climates.

Where the 500L size earns its keep

The sweet spot for a 500L tracked mixer is any job where concrete has to travel more than a few meters over bad ground:

  • Rural and village road repairs — patch a culvert or a gate approach in one batch
  • Orchard and irrigation projects — channel lining, sumps and valve boxes
  • Farming compounds — floors, cattle pens, feed bunkers
  • Small commercial jobs — footpaths, parking edges, light retaining walls
  • Greenhouse and nursery floors, where narrow aisles rule out bigger machinery

What buyers usually ask

Can it mix on the move? Yes — the drum keeps turning from the mixing point to the pour, which keeps the batch consistent even across a long access path.

Is it easy to operate? The machine is walk-along remote-free: throttle, drum and tracks are controlled at the console, so one operator handles everything.

What about spare parts and service? We keep a full parts list for every model we sell and ship spares worldwide — the R420 engine family is widely available locally in most markets.
