  • Patent number: 5462309
    Abstract: Counterweights are useful in stabilizing a work machine to increase the traction to a pair of wheels on one end when a implement is attached to the opposite end of the machine. The subject counterweight arrangement includes a base weight which is removably attached to the machine frame. A plurality of add-on weights are removably attached beneath the base weight by a u-shaped bolt. This arrangement of components provides a simple compact structure to counteract the weight of the implement attached to the opposite end of the machine and also provides a way to add or subtract weight to offset the the addition or subtraction of mechanisms to the end of the backhoe stick assembly.
