LEO PARADIS may have built the next best thing to a better mousetrap-a mini-grader that squeezes through narrow doors but does a big grader job.
And although the world hasn't yet beaten a path to his doorstep, he says so many contractors are hiring his machine that he's building another one. Laser Grader Early Days The Original Article As it Appeared Laser Grader Laser Grading Leo Paradis of Precision Grading uses his homemade mini-grader to fine-grade the gravel base for a concrete floor in a commercial building. At left is the Spectra-Physics Electronic Level which he uses to guide the grader's moldboard during the precision leveling operation. Paradis built the machine right from scratch. It features an 18-hp Cushman golf cart gasoline engine which powers a Vickers six-gailon oil pump and which in turn drives the Charlin hydraulic motor -the primary mover for the entire hydraulic system. Because of the hydrostatic drive and the gearing he used, he said the 18 hp is actually boosted to 119 wheel horsepower, giving him all the power and infinite speed he needs for the job. The six lever hydraulic controls raise and lower the dozer blade, raise and lower the moldboard, move it laterally and vary the angle of the blade. The mold board itself is made from a ten-inch-diameter steel pipe, while the cutting blade is a standard manufacturer's piece. Giving him the precision and production he needs. The SpectraPhysics ELI Electronic Level he bought from Waste, Inc. of Concord, N.H. The level provides an invisible electronic signal which is picked up by a target sensor mounted on the grader's moldboard. Set up above the grader's hydraulic controls, and wired to the target sensor, is a remote display which tells Paradis whether his blade is too high, too low, or on target for the predetermined grade. "When I first started using the minigrader," he said, "I didn't have the electronic level.
