Since lawn mowing employees spend large amounts of time
performing these repetitive tasks, it is crucial that measures are
taken to reduce discomfort and minimize fatigue during operation
in order to prevent WRMDs. A local manufacturing company contracted
the researchers for an ergonomic analysis of their current
commercial lawn mower handle geometry. 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. There is no formal ergonomic
comparison of handle geometries. The lawn mower under investigation
allows landscapers to set a speed and release the control
bar to accelerate. By engaging the control bar, the landscaper can
brake (by engaging both control bars on the right and left), turn left
(by engaging the left control bar), turn right (by engaging the right
