Before backing under a trailer parked on soft or uneven ground, what extra check protects the landing gear?
- A.Confirm the ground will support the gear feet and use pads or planks if the feet could sink once the tractor pulls out
- B.Remove the crank handle
- C.Leave the gear fully retracted
- D.Paint the gear feet a bright color
Correct answer
A. Confirm the ground will support the gear feet and use pads or planks if the feet could sink once the tractor pulls out
Why
All of the trailer's nose weight lands on two small feet once the tractor leaves. If those feet sink or punch through soft asphalt on a hot day, the trailer can tip or drop, so spreading the load first is cheap insurance.
