What is the difference between a scraper and grader?

Why do the front wheels tilt on a road grader?
They have Adjustable Leaning Wheels [that] the operator can lean in either direction to lean the weight of the grader toward and balance the weight against the side load of earth on the blade—the heavier the load, the more the operator leans the wheels and weight of the machine.”
Why are front grader tires backwards?
On the drive tires the tires are pulling on the ground to move the machine forward. On the front the ground is pushing back on the tires to make them roll so they are turned backwards to get the same cleaning effect as the rears. Without it they would just ball up and slide.

Why are front tractor tires tilted?
Why do the front tires on my tractor appear to be off center? The front wheels are intended to have positive camber (toe-in). The positive camber or “toe-in” is generally used in vehicles for off-road use. In such vehicles, the positive camber angle helps to achieve a lower steering effort.
