and is a different
culprit than mud or snow,
but it does just as much
damage when it’s wet and
packed in place on the grader. So
keep these “sand stoppers” in mind when you park the vehicle after the day’s run.
Bracket Slide and Glide
Sand can play havoc with the cylinder rod
end brackets (top) on the blade’s moldboard,
especially when it’s wet and hardens.
When packed sand accumulates on the
moldboard, those end brackets get stuck in
their tracks, causing damage to the vehicle’s
hydraulics and the moldboard’s slide bushings
and seals. That means your grading operations
are put on hold!
To head off damage, eyeball the top area of
the moldboard for hard-packed sand. Remove
any debris with a shovel or entrenching tool
before leaving the worksite. That way the
blade can slide back and forth smoothly with-
out damage to the hydraulics.

Moldboard Clean-Up
O
perators, remove any rocks, mud and hard-packed dirt on top of the grader’s
moldboard. The same goes for ice and snow. Do this after the day’s run.
Debris on the moldboard can
damage or stop the moldboard’s
slide bushings from moving left or
right along the guide rail during
operations. Also, a “stuck” slide
bushing puts lots of wear and tear
on the vehicle’s hydraulic system.
So, after you shut down the
engine for the day and hop out of
the cab, remember to do a little
housekeeping before you leave the
worksite or motorpool. That is,
clean any debris off the grader’s
moldboard.
