The four new N Series loader/backhoes from Case Construction Equipment increase loader breakout force, lift and reach. The new Case 580N, 580 Super N, 580 Super N Wide Track and 590 Super N loader/backhoes replace the previous M Series 3, and all feature 4.5-liter turbocharged engines, ranging from 79 hp in the 580N to 108 hp in the 590SN. The units feature the Power-Lift, which channels the hydraulic power directly to the boom with the touch of a button. The 580SN WT backhoe is designed for grading, trenching, backfilling, heavy lifting, hole-patching and rock-breaking.
