Power take-off (PTO) driveline entanglements are a primary source of injury on US farms. As with many farm injury concerns, hazard control technology is widely available for mitigating the risk of these entanglements. Despite the availability of hazard control technology, PTO shields are damaged or missing on approximately 57% of PTO driveline implements in New York. Given the catastrophic nature of entanglements and the ready access to safety technology, a better understanding of what motivates farmers to install or replace PTO shields is warranted.
To examine this question, agricultural health and safety researchers in New York State conducted an initial comparison of PTO shield sales on farms receiving one of three different interventional approaches. These included PTO shield audits, a social marketing campaign, and on-farm safety services. PTO shield purchases were tracked from January 2011 through June 2016 on farms receiving these interventions and on other farms that were not exposed to interventional strategies.
Results indicate that a significantly higher number of PTO shields were purchased on farms that requested and received on-farm safety services versus farms that were exposed to PTO shield audits, the social marketing campaign, or the control group. PTO shield sales were slightly elevated on farms receiving driveline audits, as compared with control farms (although these differences were not significant).
No marked differences in sales were noted between control farms and farms exposed to the social marketing campaign. Only one of the three interventional strategies (on-farm safety services) approached the number of PTO shield sales necessary to prevent an entanglement.
动力输出（PTO）传动系统缠绕是美国农场受伤的主要原因。与许多农场伤害问题一样，有广泛可用的危险控制技术来降低这些缠绕风险。尽管有危险控制技术，但在纽约，约57%的动力输出传动系统农具上的动力输出防护装置损坏或缺失。鉴于缠绕的灾难性本质以及安全技术易于获取，有必要更好地了解促使农民安装或更换动力输出防护装置的因素。
为研究此问题，纽约州的农业健康与安全研究人员对接受三种不同干预方法之一的农场的动力输出防护装置销售情况进行了初步比较。这些方法包括动力输出防护装置审计、社会营销活动和农场安全服务。在2011年1月至2016年6月期间，对接受这些干预措施的农场以及未接触干预策略的其他农场的动力输出防护装置购买情况进行了跟踪。
结果表明，与接受动力输出防护装置审计、社会营销活动的农场或对照组相比，请求并接受农场安全服务的农场购买的动力输出防护装置数量显著更多。与对照农场相比，接受传动系统审计的农场的动力输出防护装置销售略有增加（尽管这些差异不显著）。
对照农场与参与社会营销活动的农场之间的销售情况没有明显差异。三种干预策略中只有一种（农场安全服务）接近预防缠绕所需的动力输出防护装置销售数量。
