The 90Z-1 zero tailswing excavator has been added to JCB lineup. The excavator has an operating weight of 18,975 pounds with a 74-horsepower JCB by Kohler engine that meets Tier 4-Final requirements. Maximum digging depth is 13 feet 7 inches, dump height is 17 feet 9 inches, and reach at ground level is 24 feet 3 inches. A patented, reduced-loss hydraulic system operates with reduced back pressure which eliminates parasitic losses while placing less demand on the engine, JCB says.
