If it means a little shovel work
before unhooking, consider how
much more work you’ll have re-
covering the trailer and its cargo if
you don’t shovel.

ulling a semitrailer requires a driver’s
complete attention. So does hooking
up to and pulling out from under the
trailer.
You can easily damage the landing
gear and legs if you don’t pay atten-
tion to hookups and drops.
For instance:
After hookup, raise the landing gear
legs completely before moving out. If
you hook up and take off without com-
pletely raising the legs, they will hit
the ground or something laying on it.
A heavy load pushes the legs into
mud, sand or snow. Cargo can shift
and tumble off.
So, use landing pads if you still
have them. Otherwise put boards
under the legs to provide an even
surface when you must drop a
trailer on soft or uneven ground.
You’re left with bent or broken legs, a
tossed load or a ruined trailer.
Before pulling the tractor out from
under the trailer, always lower the
legs completely and make sure the
ground underneath the legs is as even
as possible.
If you pull out and both legs don’t
touch ground at the same time, the
trailer can come crashing down.
