For PTO shaft guards, check that the guard is:
- made to a recognised standard such as BS EN ISO 5674;
- the correct size and length for the shaft, both when closed and when extended;
- a non-rotating type, with the restraining device (for example, securing chains) in place;
- properly used and maintained. Clean and lubricate guards regularly;
- supported when not connected. Do not rest it on the drawbar or drop it on the ground, and do not suspend it by the restraining device;
- safe from damage, for example, by livestock, when the machine is in store.
Make sure no one uses adaptors to allow a 21 spline 1000 rpm shaft to drive a 6 spline 540 rpm shaft.
