WAC 296-307-076
How must farm field equipment be guarded? "Farm field equipment" means tractors or implements, including
self-propelled implements, used in agricultural operations.
(1) All power transmission components must be guarded
according to WAC 296-307-280.
(2) The manufacturer's instruction manual, if published by
the manufacturer and currently available, must be the source of
information for the safe operation and maintenance of field
equipment.
(3) You must ensure that all power takeoff shafts, including
rear, mid-mounted or side-mounted shafts, are guarded by a master
shield, as follows:
(a) The rear power takeoff has a master shield. The master
shield is strong enough to prevent permanent deformation of the
shield when a 250-pound operator mounts or dismounts the tractor
using the shield as a step.
(b) Power takeoff driven equipment is guarded to prevent
employee contact with rotating members of the power drive system.
When the tractor master shield must be removed to use specific
power takeoff driven equipment, the equipment must provide
protection from the part of the tractor power takeoff shaft that
protrudes from the tractor.
(c) Signs are placed at prominent locations on the tractor
and on power takeoff driven equipment requiring that safety
shields are kept in place.
(4) The following functional components must be shielded to
a degree consistent with the intended function and operator's
vision of the component.
• Snapping or husking rolls;
• Straw spreaders and choppers;
• Cutterbars;
• Flail rotors;
• Rotary beaters;
• Mixing augers;
• Feed rolls;
• Conveying augers;
• Rotary tillers; and
• Similar units that must be exposed for proper function
(5) Where removing a guard or access door will expose an
employee to any component that continues to rotate after the
power is disengaged, you must provide, in the immediate area:
(a) A safety sign warning the employee to look and listen
for evidence of rotation and to wait until all components have
stopped before removing the guard or access door.
(b) A readily visible or audible warning of rotation on
equipment manufactured after October 25, 1976.
(6) If the mounting steps or ladder and the handholds of the
propelling vehicle are made inaccessible by installation of other
equipment, other steps and handholds must be provided on the
equipment.
(7) You must ensure that the operator's steps and platform
have a slip-resistant covering to minimize the possibility of
slipping.
(8) Powered machines not driven by an individual motor must
have a clutch or other effective means of stopping.
(9) All friction clutches must have sufficient clearance and
be kept adjusted to prevent drag or creeping when disengaged.
