Abstract

The improved hydraulically operated post pulling apparatus is adapted to be mounted on a vehicle such as a skid steer mover. The post puller apparatus includes a support frame adapted to be mounted on the vehicle. The support frame includes a number of base member brackets that attach a base member or base plate to the support frame. The base member includes a post receiving recess that is adapted to receive a post from the side rather than the top. The post pulling apparatus also includes a top support plate that includes a post receiving indent, which also is adapted to receive a post from the side rather than the top. A rotating jaw member having a member of post-engaging teeth is pivotally mounted next to the post receiving indent on the top support plate. Opposite the rotating jaw member, a fixed jaw member is attached to the top support plate that includes a number of post-engaging faces. A clamping cylinder is mounted to the top support plate and includes a piston that is pivotally attached to the rotating jaw member. The piston, when extended, operates to pivot the rotating jaw member downwardly into engagement with the post to be engaged and removed from the ground. First and second pairs of bar links are each pivotally mounted at one end to the support frame and pivotally mounted at an opposite end to a forward panel that is preferably attached to the rear of the support plate. A pair of pulling hydraulic cylinders are mounted on the base member, each having a piston attached to the top support plate. When the pistons of the pulling hydraulic cylinders are extended, the bar link pivot allowing the top support plate to lift and raise the pole from the ground.
