Driveline Safety
Agriculture and forestry are very hazardous occupations.
Today’s farmer spends long hours
close
to increasingly complex and powerful machinery.
To avoid accidents, everyone from the component supplier and the company that manufacturers
and assembles the machinery to the dealers and ultimately the actual user must keep safety in
mind. The checklist below relates to the driveline of agricultural implements, general safety
literature, and the standards published by the American Society of Agricultural Engineers.

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, speed of rotation, 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.
◼
For the tractor's PTO shaft connections, specify a safety type yoke (twist or slide collar) to
minimize protrusions.
◼
Provide a proper clearance zone for the driveline operation to avoid damaging the shielding
components.
Some common areas of interference are:
◼
Three-point linkage.
◼
Extended or eye loop hitch pins.
◼
Hydraulic hoses.
