This handle geometry
was very different than traditional commercial lawnmower. Based
on a search of other commercially available lawn mowers, the
common control systems are currently a straight bar or a pistol
position (Fig. 5). The manufacturing company specifically cited
pistol position as their main competitor. Since the pistol position is
the most similar to the nontraditional control system (NCS), this
research aimed to determine a significant postural and comfort
differential between the systems.
