To avoid serious injury or death: Make certain driveline
yokes are securely fastened at each end. A loose yoke can work
free allowing the driveline to rotate uncontrollably causing
implement damage and bodily injury or death to anyone
Refer to Figure 1-21:
The main driveline (#5) may be either constant velocity
type or conventional type. Pull-collar couplers and
retaining bolts are used to connect the driveline to the
tractor and implement gearbox, respectively.
