Abstract
A mechanical pruner has a hinged trimming head that allows the trimming of grape vines growing on sloped ground. The trimming head has hedgers with forward facing cutting teeth and rotating combers that open up the grape vine canopy and pull the vines into the cutting path. By also allowing for multiple adjustments in the height of the pruner, lateral position of the trimming head, lateral position of the hedger relative to the trimming head, and both the lateral and vertical positions of the combers relative to the trimming head, the mechanical pruner provides a user with significant control over the trimming of grapevines.
