A harvesting machine for nuts and stone fruits including an articulated body with a front part and a back part. A tree shaker head is detachable and couples to the front part of the harvesting machine by a C-frame mount. The articulated body with a low clearance provides necessary maneuverability in an orchard environment, while permitting the harvesting machine with the shaker head detached, to function as a general purpose orchard machine for mowing, spraying, brush clearing and other associated tasks. Specialized machinery for these tasks is no longer necessary.
