PEELING AND SCRAPING BACKFILLING 6” Use a slight bucket angle, travel forward, and hold the lift control forward to start the cut. Make a short, angle cut approximately 6” deep and break-out cleanly. With the bucket level, start a cut at the notch approx- imately 2” deep. Hold the depth by feathering the bucket control to adjust the cutting l[...]

Leave dirt in the bucket because dumping on each pass wastes time. Operate at right angles to the ditch. Take as big a bite as the tractor can handle without lugging down. DITCH SOIL PILE DITCH Leave dirt which drifts over the side of the bucket for final clean-up. Pile dirt on the high side for easier backfilling on a slope. HANDLING LARGE HEAVY O[...]
