stopped before stepping into the hitching position. If possible,
arrange the hitch point so that the tractor can be backed into position
without anyone between. Always know what the other person is
doing.
Failure to safely block up equipment can result in a fatal crushing injury. A jack may slip, a hose or
overhead support may break, or the equipment may roll. Take extra precautions when working with
machinery that is raised for any reason. The operator's head or chest can be crushed between the
equipment and a low beam or other part of a farm building. These accidents usually occur when the
machine is being operated in reverse. Tree limbs are also potential hazards when working with tractors
and other machinery.
To prevent being crushed or pinned, recognize and avoid potentially dangerous situations. Block all
machinery securely if you must work under it. If an implement can roll freely, block its wheels so it
cannot roll.
Free-Wheeling Parts
Many machine parts continue to spin after the power is shut off, including cutter heads of forage
harvesters, hammer mills of feed grinders, rotary mower blades, fans and flywheels. Never touch these
parts until they have stopped moving. This could take 2 to 21/2 minutes.
Springs
Compressed springs (Fig. 4) will expand with great force when
released, and springs that are stretched will contract rapidly when
released. Know what direction a spring will move and how it might
affect another machine part when released, and stay out of its path.
Burn Points
Be aware of burn points: mufflers, manifolds and even gear cases under adverse climatic conditions.
They may not be severe enough to seriously maim, but they can startle the operator enough to cause
him or her to "jump" into more deadly danger.
Hydraulic Systems
Hydraulic systems contain fluid under extreme pressure. Before loosening, tightening, removing or
otherwise working with any fittings or parts, relieve this pressure. Jet streams from even pinhole leaks
can penetrate flesh. In addition, the liquid is often hot.
