The Level Best laser grading box utilizes lasers, machine control technology,
and a digital proportional valve to dramatically increase grade accuracy. Using
this technology, operators can reach grade faster and easier. The Level Best
laser grading box's accuracy allows for more precise material estimates
which reduces overages and saves time.
How It Works
The laser machine controls are easy to learn and use. As the operator grades,
the system's receiver detects laser light from a rotating beacon and transmits
a signal to the Level Best hydraulic controls. The proportional hydraulic valve
uses the signal from the receiver and automatically lowers or raises the grader
box to the required grade. Precise finish grade is attained when the on-grade
light remains illuminated. The finish grade elevation is consistently level
to within 1/4" or 1/8", depending on the laser system used and the deadband setting.

The Level Best Advantage
Â
The Level Best system can grade up to 50,000 square feet in an eight-hour day
without need for costly motor-graders, dozers, or tractor-loader backhoes. Other
laser techniques require two to three people to achieve finish grade--the Level
Best system requires only a single operator.
     The laser-controlled hydraulic system is also unique to the Level Best
grading system. This hydraulic system utilizes digital-proportional valve bodies
for greater accuracy and reliability than other systems on the market.
Features
Constructed of 3/8" and 1/4" steel plate and heavy-wall steel tubing,
the Level Best grading system is built to take daily abuse on a job
site.
Large, Heavy-Duty Casters withstand years of punishment. Heavy-Duty
Wheel Hub and Bearing Assemblies need only annual greasing, reducing maintenance
time and cost.
Epoxy-Fiberglass Composite Bushings in all pivot points. This eliminates
the need for greasing. The inexpensive, replaceable bushings wear instead
of your grading box.
The Level Best's foam-filled tires eliminate blow-outs from hazards
on the jobsite.
Cutting edges, made of long wearing high-carbon steel, can be reversed
for twice the life or replaced in a matter of minutes.
Tough, long-lasting powder-coating ensures that a Level Best grader
box will look great for years to come.
Together, these tough and unique features have proven themselves over
time with more than 250,000,000 square feet of sub-base grading.
Draw Bar Option
Features & Benefits
Long, 48" Draw Bar- The
long draw bar maximizes the distance between the tractor axle and the
wheels of the Level Best grading box, allowing you to reach grade faster.
Adjustable Top Link- A
top link between the draw bar and the grade box allows the operator
to adjust the pitch of the box. Adjusting
the pitch of the box helps to keep the end plates from digging into
graded material, making a neater finish.
Adjustable Hitch- An adjustable hitch accommodates the hitch heights of most tractors or
trucks.
Retrofits
to older Level Best Boxes- The draw bar option can be retrofitted to older Level
Best boxes. Converting an older
box to the draw bar option requires only one hour.
