Guard interlocking for PTO driven machinery

Describes research undertaken concerning the development of a prototype guard interlocking system (interlocking PTO (power take-off) driveline decoupling with the existing implement hinged guards), suitable for use with a wide range of PTO driven agricultural machinery in the UK. The aim of this research was to reduce the likelihood of operator injury. Agricultural accident statistics, equipment sales data and design trends are reviewed to identify and assess the risk(s) associated with PTO driven machines; to identify pertinent tractor and implement design features; and to identify potential guard interlocking systems that may be utilised on PTO driven machinery.

Some of these research reports are very large. For information about expected download times please see our FAQs pages.
