Hand signals are an ideal communication tool when working around noisy farm machinery. To help everyone communicate in the same "language," the American Society of Agricultural Engineers has adopted 11 uniform hand signals for agricultural safety.
These signals should be learned and used by the farm family, employees and farm visitors such as feed truck drivers, chemical salespeople and Extension agents.
Using standard signals can help:
THIS FAR TO GOPlace palms at ear level, facing
head, and move laterally inward to
indicate remaining distance to go.
COME TO MERaise the arm vertically
overhead, palm to the front,
and rotate in large horizontal
MOVE TOWARD MEPoint toward person(s), vehicle(s),
unit(s); beckon by holding the arm

MOVE OUTFace the desired direction of movement;
hold the arm extended to the rear; then
swing it overhead and forward in the

horizontal palm down.
STOPRaise the hand upward to the full
extent of the arm and back to the
shoulder rapidly several times.
SPEED UPRaise the hand to the shoulder, fist
closed; thrust the fist upward to the
full extent of the arm and back to
the shoulder rapidly several times.
SLOW DOWNExtend the arm horizontally sideward,
palm down, and wave arm downward 45°
minimum several times, keeping the arm
straight. Do not move the arm above
START ENGINESimulate cranking of vehicles by
moving arm in a circular motion at
STOP ENGINEDraw either hand, palm down across
the neck in a "throat-cutting" motion.
LOWER EQUIPMENTMake circular motion with either
hand pointing to the ground.
RAISE EQUIPMENTMake circular motion with either
