Abstract
A gradient measuring apparatus includes a gimbal assembly operably supported in a construction vehicle for viewing by an operator to see gradient indications in fore-aft and sideways directions. The gimbal assembly includes an outer orb with pointer that moves with the vehicle, and an inner orb with concentric circles that stays in a true vertical by gravitational forces, the combination of which simultaneously accurately reflects a fore-aft and sideways grade at which a ground surface is being cut in an excavating process.
