◼
Read and follow instructions on PTO safety decals.
◼
Stay alert and pay attention when PTO is operating.
◼
Keep bystanders, especially children, away from the PTO driveline.
◼
Check the driveline to ensure it is attached securely to the tractor.
◼
Keep guards and shields in place at all times while operating. Disengage PTO, shut off the
power source, and ensure all moving parts have come to a complete stop before removing
guards or shields.
◼
Clothing worn by the operator must be pretty tight. Never wear loose-fitted jackets, shirts, or
pants when working around the PTO. Tie long hair back or put it under a cap.
◼
Keep hydraulic hoses, chains, and other items from contacting the driveline.
◼
Do not exceed the recommended 540 rpm PTO operating speed.
◼
Before inspecting or servicing the PTO drive area, disengage the driveline, shut off the power
source, and ensure all moving parts have come to a complete stop.
◼
Keep hands, feet, and clothing away from all PTO drive parts.
◼
Do not clean or touch the PTO shaft when it is running.
3.9.1 Driveline Safety Checklist
Driveline Specifications
The first step toward safe applications is to specify and test the driveline to operate appropriately
under expected field conditions.
◼
Specify and test the proper size joints and telescoping members based on the power required
by the implement, rotation speed, joint angles, shock loads, and expected lifetime.
◼
Test the hitch geometry to prevent the driveline from:
•
Extending beyond the recommended maximum length.
•
Bottoming out.
•
Reaching a position that allows universal joints to lock.
•
Exceeding the maximum allowable angle for the constant velocity of the universal joints.
You can find information concerning these parameters in all driveline manufacturer’s catalogs.
◼
Specify and test telescoping members to allow the lowest possible thrust loads, considering the
expected working conditions.
◼
Specify and test torque limiters to control excessive shock loads.
◼
Specify and test overrunning clutches to prevent inertial loads from overpowering the tractor.
Hazard Reduction
The second step in specifying a safe driveline application is to strive to eliminate as many hazards
as possible
◼
On a driveline with torque limiting or overrunning devices, specify that this device is positioned
at the end of the driveline near the implement.
◼
To implement connections that require bolts or set screws, select and/or supply hardware that
minimizes protrusions. You can find Information concerning these parameters in all driveline
manufacturer’s catalogs.
