BMi power trowels come in both walk-behind and ride-on models. The B430E 30-in.-path model is mounted with a 1.5-hp, 110-V, 15-A, 60-Hz motor. Ideal for basement and indoor use with zero emissions, the lightweight machine features a removable motor subassembly for easy transport and handling. The ride-on trowel line ranges in paths from 65 to 92¼ inches, features overlapping and nonoverlapping finishing options, and are equipped with heavy-duty gearboxes for longer life and less maintenance.
