ABSTRACT:
An apparatus for excavating and transplanting trees includes a plurality of blade assemblies mounted on the sides of a horizontal multi-sided frame for overlying and substantially surrounding an excavation site. Each blade assembly includes a housing within which a flanged blade and stem unit can be mounted for reciprocation to effect penetration of the excavation site, and a hydraulic cylinder and piston assembly detachably affixable to the stem for effecting reciprocation of the blade and stem unit. Within each housing are mounted a plurality of rollers engageable with opposite sides of the blade thereof, a pair of guide blocks adjacent opposite sides of the blade flange, and a pair of guide bars on opposite sides of the stem, all cooperable to guide and maintain the blade and stem unit in an established path during reciprocation. Associated with each housing is one curved and one straight blade and stem unit selectively and alternately mountable therein for reciprocation, the arcuate blades, when mounted in the housings and reciprocated, following arcuate paths to remove a generally conical section from the excavation area and the straight blades, when so mounted and reciprocated, following straight paths to remove a frusto-conical or frustum-shaped section from the excavation area.
