Use a shovel to scoop out mud
that’s collected between and on
rollers and drive sprockets.

areful, operators, where you park
your dozer, loader, grader or scraper
overnight. Mud that’s soft during the
day can freeze as hard as concrete when
temperatures plummet overnight, leav-
ing your equipment stuck fast.
Don’t think you can rock your vehicle
loose, either. You’ll break a dozer’s track
or snap its drive sprocket teeth. On the
loader, you’ll damage the U-joints. Try-
ing to move a grader or scraper mold-
board that’s stuck in the mud damages
the vehicle’s hydraulics.
The time to prevent these problems
is the night before:
Park your vehicle on high ground
if possible. Water drains downhill so
the mud won’t be quite as deep.
Avoid parking in the deep ruts
worn by other vehicles. Some are deep
enough to bottom out your vehicle’s
frame. Park your vehicle there and you
might not move it until late spring.
Construction Equipment . . .
Put a board between the ground
and any moldboard. That way the mud
can’t freeze the moldboard in place.

A
lways get a buddy to
help you when you want
to remove the SEE’s
hood for service checks.
Then, remember to lift
before sliding the hood
out sideways.
That’s because of the
wires that clip into the
brake and clutch fluid
reservoir sending unit.
They stick out like a
sore thumb.
It’s easy to tear them
loose if you just slide off the hood without lifting it first. Once the wires are
broken, you won’t get a reading inside the cab when the fluid levels are low or
when the brake pads are worn.
If you remember to lift the hood clear of the reservoir’s wires when you and
your buddy remove it, you won’t have to worry about that disconnect.

echanics, the parts info for SEE and
HMMH shock absorbers in Figs 189 and
190 of TM 5-2420-224-24P is wrong.
NSN 2510-01-298-8417 (Item 4 in Fig 189) gets
the front shock absorber for the HMMH only.
NSN 2510-01-256-9156 (Item 5 in Fig 190)
gets the HMMH’s rear shock absorber and
the front and rear shock absorbers for the
SEE.
Never swap the front and back shock
absorbers of an HMMH. The front shocks come
with a port that connects into a hydraulic line for
suspension lockout during forklift operations.
