Case Construction Equipment™s M Series 3 backhoe lineup includes the 580M, 580 Super M, 580 Super M+, 590 Super M and 590 Super M+. The five models range in net horsepower from 79 to 109 with dig depths from 14 feet 3 inches on the standard backhoe to 20 feet 4 inches with the Case Extendahoe. The loader end on the series has an electronic auxiliary control, which allows precise, easy control of attachments such as the 4-in-1 bucket. The backhoes are now available with a one-touch idle built into the machine™s pilot controls, which allow you to return the engine to idle at the touch of the button instead of using the rotary hand throttle. Pressing the button a second time returns the engine up to the previous rpm setting.
