Graders and Soil Stabilizers

Motor graders cut precise grades with a long-wheelbase frame and center-mounted moldboard. The catalog covers machines from compact municipal graders to full highway class.

Fonctionnement

The moldboard rotates, tilts, and shifts sideways under hydraulic control while articulation and leaning front wheels hold the machine stable on slopes and windrows. Passes progressively move material toward grade, and GPS or cross-slope machine control now holds tolerances measured in fractions of an inch.

Types et variantes

Motor Grader
Long-frame machine with a center blade for precise grading of roads and pads.

Comment choisir

Grader selection follows blade width and horsepower against the road or pad width and material volume. Compact graders serve municipal streets, gravel road maintenance, and fine grading between curbs; full-size machines cut highway subgrades and manage large earthwork finishing. Operator skill or machine-control automation is a genuine factor — the grader is the least forgiving earthmover to run well.

Questions fréquentes

What is a motor grader used for?
Fine grading and shaping: road subgrades and gravel surfaces, crowns and ditches, building pads, and snow removal — anywhere a surface must hit grade within tight tolerance.
Why is the blade mounted mid-frame?
Averaging. With axles far ahead of and behind the moldboard, the blade bridges bumps and hollows instead of reproducing them, which is what makes a grader accurate.
What sets grader sizes apart?
Moldboard width and power. Compact machines fit subdivision streets and trail work; 14 ft-class machines are the highway standard for production grading.
