Rotary Tiller gearbox kits by Omni Gear have been designed as configurable systems with options available to fill any manufacturer's needs. Each kit is available in a number of styles while still being offered as individual gearboxes. Options include carburized alloy steel spur gearing, a choice of many input and output shafts and an interchangeable right angle drive. Omni's RTS side box design eliminates the need for chain boxes and the maintenance associated with them. Each of the kits has been designed with a corresponding bearing housing.
