The backhoe is a magnificent digging device and is reasonably safe when properly controlled by an experienced operator. As illustrated in the drawing, the backhoe, however, is subject to overturning if swung with a heavy bucket load; the backhoe is subject to flipping onto its back under certain situations of fixed rock or stump attack. The representative backhoe has an articulated digger arm and digger bucket, with hydraulic cylinders to provide motive power. There are two outriggers, which in normal operation are used to hoist the big drive wheels off the ground. It is fairly usual to combine the backhoe with a front loader; a load of dirt or rocks in the front loader bucket is often used as a safety counterbalance for backhoe work. The machine sits on outriggers and bucket, with wheels aloft.
