Case study

A 26-year-old stockman was adapting the pump

unit of a slurry tanker to provide vacuum drive

to a milking unit. On stepping over the partially

unguarded PTO shaft his left trouser leg became

entangled in the revolving PTO, resulting in his leg

being severed.

Guarding

■ Protect the tractor PTO with a shield covering the

top and both sides of the PTO so that it stops

anyone making contact with it, either with parts of

their body or their clothes. Make sure this shield

is well constructed and capable of supporting a

downward load of at least 120 kg. When the PTO

is not in use, it may be covered by a fixed cap.

■ Guard PTO drive shafts by enclosing them along

their full length, from the tractor to the first bearing

on the machine.

■ Advice on guard dimensions and design

specifications for agricultural PTO drive shaft

guards is given in:

– BS EN 12965:2003+A2:2009 Tractors and

machinery for agriculture and forestry. Power
