Abstract
The post puller may comprise an equipment coupler, a post coupler, a linkage, and an elastic cord. The post puller may be configured to detachably couple to a lifting subsystem of a piece of equipment via the equipment coupler and to a post via the post coupler. The post puller may be operable to pull the post out of the ground as the piece of equipment moves the post puller rearward and upward. The elastic cord may cause the post puller to release the post once the post is out of the ground. As non-limiting examples, the piece of equipment may be a tractor, or a front loader and the lifting subsystem may be a pallet fork or a bucket.
Claims20
A post puller, comprising:
- an equipment coupler having a pallet fork interface, a bucket interface and an upper linkage interface;
- a post coupler having a post coupler left wall, a post coupler right wall, a post coupler front wall, and a post coupler rear wall, the post coupler includes a lower linkage interface disposed on a front side of the post coupler that is adapted to grasp a post;
- a linkage having a top, a bottom, a left linkage armature with a top and a bottom, a right linkage armature with a top and a bottom, an upper linkage brace, and a lower linkage brace, the upper linkage interface is disposed beneath the pallet fork interface that pivotably couples the equipment coupler on the top of the linkage and the lower linkage interface pivotably couples the post coupler to the bottom of the linkage;
- and
- an elastic cord having a top and a bottom, the elastic cord retains the post coupler in a substantially horizontal orientation until the post coupler is adapted to be tilted during removal of the post.
