Abstract
A frame having a pair of upstanding side members is attached to the three point hitch of a tractor. The frame includes a base which can rest upon the ground adjacent a post to be removed from the ground. A plate is slidably attached for vertical movement along the side members and includes a hydraulically operated clamp for attachment to the post. A hydraulic cylinder is attached between the top of the frame and the plate and pulls the frame vertically after the clamp is attached to the post.

A pulling device comprising, in combination:
- an upstanding frame, a ground engaging base connected at the bottom of said frame;
- a plate member slidably connected to said frame for vertical movement along said frame;
- powered means connected between said frame and said plate member for causing powered movement of said plate;
- and
- clamp means attached to and movable with said plate member for clamping a post to be removed from the ground, said frame including a pair of side members, a pair of sleeves at least partially surrounding each of said side members and attached to said plate for slidably connecting said plate to said side members, said clamp means including one fixed jaw attached to said plate and one movable jaw slidably connected to said plate, jaw movement means connected to said movable jaw for causing movement of said jaw movable to and from said fixed jaw, said frame including a top member extending between said side members and said powered movement means including a first hydraulic cylinder extending between said top member and said plate, a mounting arm connected to said movable jaw, a slot formed in said plate and receiving said mounting arm slidably therein, said jaw movement means including a second hydraulic cylinder connected to said mounting arm.
In combination with an upright frame including a pair of upright side members, a pair of sleeve members slidably mounted on said side members therealong, an edge upstanding plate extending and secured between said sleeve members, an outstanding fixed jaw carried by and projecting outwardly of one side of said plate between said sleeve members and adjacent one sleeve member and facing toward the other sleeve member, said plate having a horizontal slot formed therethrough between said fixed jaw and said other sleeve member, said other side of said plate having elongated guide structure supported therefrom extending along said slot, an elongated movable jaw extending and slidable through said slot including a head on one end guidingly engaged with said guide structure and with the other end of said movable jaw opposing and movable toward and away from said fixed jaw, and motor means operatively connected between said head and one of said sleeves for shifting said head along said guide structure and said jaw through said slot.
