The IMER HSM 6, model 1130061, is a towable horizontal shaft mortar mixer with a steel drum and a Honda GX 160 5.5 hp gas engine. It mixes mortar, stucco and grout, with a 6 cu ft batch output and a bag capacity of 2 to 2.5 bags.

Power reaches the paddles through an enclosed gearbox, which runs quieter with less heat and gear wear; the listed noise level is under 79 dB. An extra large safety grate is standard, a locking handle prevents unexpected dumping, the pillow blocks are mounted externally, and the unit has forklift pockets.

The mixer weighs 500 lbs and measures 45 in wide, 55 in high and 75 in long (94-1/2 in with the tow bar), with a 57-1/2 in charging height and 5.3 x 12 in tires. A 2 in ball hitch is standard; a pintle hitch is available and must be selected at the time of purchase. Spiral mixing blades and a torsion bar axle are optional. The electric steel-drum version is model 1130062.
