Abstract
An improved post puller includes a U-shaped grapple and a pivot mount providing both a generally vertical pivot position for connection of the grapple to a draw bar and a base for mounting an operating handle thereto. One alternate embodiment provides adjustability. Further, the handle and pivot axis are specifically disposed in varying alternate positions for first rotating the grapple to grasp a post and then to permit rotation about another axis for post pulling. Another alternate embodiment includes a double grapple and actuating apparatus for opening and closing it about a post.
Claims17
Apparatus for use with a three-point tractor hitch having a draw bar means being upwardly movable and being rotatable about a substantially horizontal first axis, said apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to said draw bar means for pivoting about a second axis perpendicular to said first axis, and
- handle means attached to said pivot mounting means on an opposite side of said second axis from said grapple, said handle means extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said first axis and said second axis, whereby said jaws are operable to engage a post, pivoting said grapple about said first axis, and pull said post from the ground when said draw bar is moved upwardly.
Apparatus for use with a three-point tractor hitch having a draw bar means being upwardly movable and being rotatable about a substantially horizontal first axis, said apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to said draw bar means for pivoting about a second axis perpendicular to said first axis, and
- handle means attached to said pivot mounting means between said one jaw and said second axis, said handle means extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said first axis and said second axis, whereby said jaws are operable to engage a post, pivot said grapple about said first axis, and pull said post from the ground when said draw bar is moved upwardly.
Apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to a draw bar means for pivoting about an axis perpendicular to the horizontal, and
- handle means attached to said pivot mounting means on an opposite side of said axis from said grapple, said handle means extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said axis and about a horizontal axis, whereby said jaws are operable to engage a post, pivot said grapple about said first axis, and pull said post from the ground when said apparatus is raised.
Apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to a draw bar means for pivoting about an axis perpendicular to the horizontal, and
- handle means attached to said pivot mounting means between said one jaw and said axis, said handle means extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said axis and about a horizontal axis, whereby said jaws are operable to engage a post, pivot said grapple about said first axis, and pull said post from the ground when said apparatus is raised.
Apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to a draw bar means for pivoting about an axis perpendicular to the horizontal, and
- handle means attached to said pivot mounting means and having a lower end extending therethrough, said handle means extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said axis and about a horizontal axis, whereby said jaws are operable to engage a post, pivot said grapple about said first axis, and pull said post from the ground when said apparatus is raised, and wherein said lower end of said handle includes means for pivotally attaching said apparatus to said draw bar means for raising said apparatus.
Apparatus for pulling posts and including:
- a mounting plate,
- a pair of three-sided U-shaped grapples each having forward and rearward spaced jaws joined by a bight portion,
- each grapple having an open side opening toward the other grapple,
- pivot mounting means extending from a forward jaw of each grapple, said pivot mounting means pivotally mounting each of said grapples to said mounting plate for rotation about a respective substantially vertical pivot axis,
- said jaws and bight portions being disposed in a plane substantially perpendicular to said pivot axis,
- pivotable handle means mounted on said plate, and
- means connecting said handle means to portions of said grapples outboard of said pivot mounting means whereby selective movement of said handle is operable to pivot respective rearward jaws of said grapples away from each other to open said grapples for receipt of a post, and whereby subsequent rearward movement of said handle is operable to move said rearward jaws together to close said grapples for gripping a post to pull it.
Apparatus for use with a three-point tractor hitch having a draw bar means being upwardly movable and being rotatable about a substantially horizontal first axis, said apparatus for pulling posts upwardly from the ground and comprising:
- a U-shaped, three-sided post grapple having two opposing jaws connected together and defining a grapple open at one end,
- pivot mounting means extending outwardly from one of said jaws for pivotally mounting said grapple to said draw bar means for pivoting about a second axis perpendicular to said first axis, and
- handle means attached to said pivot mounting means and extending upwardly from said pivot mounting means to permit manual pivoting of said grapple about both said first axis and said second axis, whereby said jaws are operable to engage a post, pivoting said grapple about said first axis, and pull said post from the ground when said draw bar is moved upwardly.
