Previous studies have also suggested that older farmers are more likely to operate older tractors [Gelberg et al., 1999; Voaklander et al., 1999; Sanderson et al., 2006] and are not as likely to use protective devices [Wadud et al., 1998; Pickett et al., 1999; Hwang et al., 2000]. Tractor longevity suggests that older farmers will continue operating older tractors not equipped with rollover protective structures (ROPS) rather than purchasing new equipment [Myers et al., 2009]. Until this older equipment is removed from the workplace or retrofitted with ROPS, the high rates in the agriculture/forestry/fishing industry will likely remain unchanged.
