The IMER Workman II 350, model 1105856, is a towable steel-drum multi-mixer supplied without a motor or engine. It is built to mix mortar, stucco, grout or concrete, with a 12 cu ft drum, a 9.5 cu ft batch output and up to 15 x 80 lb bags of concrete per batch.

The drum is driven by a direct drive gearbox sealed for life, with no external drive gears. The Posi-lock system locks and unlocks automatically so the drum can be stopped in any position, and aggressive paddles give fast, complete mixing. Drum diameter is 34-3/4 in and the discharge outlet height is 26-1/2 in.

For towing and handling, the mixer has a box steel frame, torsion bar suspension, pneumatic wheels, impact-resistant fenders and forklift pockets. A tow hitch ball adapter and a spare tire are included. Powered versions are model 1105855 (Honda GX 160 5.5 hp gas), 1105862 (120V 1.5 hp) and 1105863 (240V 1.5 hp).
