Bobcat extends its M-Series mini excavators (inaugurated with the E80 at World of Concrete) with the 3-metric-ton E32 and the 4-metric-ton zero-tail-swing E35. Both are powered by 33.3-horsepower diesels and dig 10 feet 2 inches deep. The new mini excavators are completely re-engineered to reduce weight. A new load-sensing piston pump and closed center-valve system is said to not only deliver smoother function control, but also increase arm breakout force by 10 percent over heavier models they replace.
