What is the risk of lowering the landing gear too fast in high gear as the trailer weight transfers?
- A.The handle can spin or kick, and the trailer can drop suddenly onto the gear, damaging it
- B.High gear is always safer
- C.The gear cannot be damaged by speed
- D.The trailer will float above the ground
Correct answer
A. The handle can spin or kick, and the trailer can drop suddenly onto the gear, damaging it
Why
As weight comes onto the gear, uncontrolled cranking can let the load drop the last distance. Controlled low-gear cranking keeps the transfer smooth and the handle in your control.
