IMER's HSM 12 is the largest towable mortar mixer in the HSM line, built around an enclosed gearbox that drives the paddles quieter and with less gear wear than an exposed-gear design. It's available with a Honda GX390 gas engine for sites without electrical service, or a 5 HP, 240V electric motor for sites with 240V power; the mixer tows on a standard 2-in ball hitch (pintle loop available on request) either way.

An extra-large safety grate and a locking handle keep the load from dumping unexpectedly, and a large grab handle makes the actual dump easy and controlled once it's deliberately released. Externally mounted pillow blocks keep the mixing shaft spinning smoothly rather than binding under load. This is built for crews mixing the largest batches the HSM line offers.

Common Applications

  • Mixing large batches of mortar, stucco, or grout on jobsites with or without electrical service
  • Towing between mixing locations rather than running a stationary unit

Selection Notes

  • Gas (Honda GX390) suits sites without electrical service; electric (5 HP, 240V only, unlike the HSM 6/8 electric models which wire for either 120V or 240V) suits sites with 240V power
  • Part of the HSM line (6/8/12 cu ft); this is the largest of the three
  • Optional torsion bar axle and optional heavy-duty spiral mixing blades (rated up to 30% faster mixing) are available on request, not standard
