Abstract
An apparatus for driving fence post into the ground operable with a tractor having a power lift mechanism with two lift arms pivotally connected to the tractor for moving upwardly and downwardly in response to hydraulic force applied thereto, the apparatus including two lever arms pivotally connected to the chassis of the tractor, a rigid bar connecting the rear ends of the two lever arms, a pivot arm member rigidly connected to the rigid bar and extending upwardly therefrom, a base member rigidly mountable on the rear of the tractor chassis having a support arm member extending upwardly therefrom, and an elongated drive member pivotally connected to the upper end of the support member and to the pivot arm member for driving posts or stakes into the ground.
Claims8
An apparatus for driving a post into the ground operable in combination with a tractor having a chassis and a power lift mechanism with two lift arms, comprising:
- a. at least two lever arm means pivotally connectable to the chassis of a tractor, said lever arm means being connectable to the lift arms of the power lift mechanism of a tractor,
- b. rigid bar means connected to each end of said lever arms means,
- c. pivot arm member means connected to said rigid bar means,
- d. base member means rigidly connectable to the chassis of a tractor,
- e. support member means rigidly connected to said base member means, said support member means having brace member means connected to said support member means and connectable to the chassis of a tractor, and a second brace member means being pivotally connected to said rigid bar means and pivotally connectable to the chassis of a tractor, and
- f. drive member means pivotally connected to said support member means and said pivot arm member means.
