What is the correct order for lowering the landing gear when uncoupling?
- A.Drop it from full height and let it slam down
- B.Lower it until it makes firm contact with the ground, then give it additional turns in low gear if the trailer is loaded
- C.Lower it only until it almost touches
- D.Raise it slightly after contact to level the trailer
Correct answer
B. Lower it until it makes firm contact with the ground, then give it additional turns in low gear if the trailer is loaded
Why
The gear must carry the trailer's front weight before the fifth wheel is opened. Extra low-gear turns after contact on a loaded trailer make sure the weight transfers without dropping.
