Activity Ideas |
- Demonstrate the proper procedures for hitching a PTO-driven implement to a tractor.
Discuss the differences in safety shields. Using a paper coverall stuffed with newspaper,
demonstrate how a PTO draws and wraps objects around it. Calculate the rotation and linear
speed of the PTO. Compare to human reaction times.
- Invite someone to the class who was injured from a PTO entanglement.
- Demonstrate the proper procedures of hitching and unhitching implements to tractors.
Include how to use the jack, safety chains and other safety features. Discuss the
difference in hitch pins and the necessity of a safety clip.
- Discuss hydraulic systems and related safety precautions. Topics to cover include: never
checking for leaks with your hand, never getting beneath a hydraulically supported
implement, correctly blocking a hydraulically-raised implement and how to clean hose
connectors.
- Discuss the importance of hand signals for communicating around machinery. Have the
class develop the hand signals that will be used for the driving course. Standard hand
signals may be used as shown in the student manual.
