Abstract
Apparatus for digging and transplanting trees and the like comprises a horizontal frame to which a plurality of sliding spade assemblies is mounted, each comprising a spade blade, a thrust tube secured to the blade and a slide housing, also secured to the blade, which surrounds a portion of the outer surface of the thrust tube. The tower is received within a channel between the thrust tube and the slide housing, so that the spade assembly may be reciprocally moved along the tower with the blade supported both inside and outside the tower for improved stress distribution and durability. The bearing surfaces of the tower and the slider are provided with linings of plastic to minimize frictional resistance.
