Abstract: A harvester for nut-bearing trees comprising a self-propelled chassis having a forwardly projecting, vertically shiftable frame carrying a tree-shaking mechanism and a flexible fabric canopy foldable from a generally transverse, transport position relative to the chassis to an inverted cone-shaped configuration surrounding the trunk and lower limbs of a tree. A portion of the cone-shaped configuration is defined by a rigid vertically inclined wall having windows for the operator to view the tree being approached and the interior of the canopy during the tree-shaking operation. Nuts, hulls and trash shaken from the tree into the canopy are carried by conveyors through a trash-separating zone and then through a dehuller. The separated nuts are then sized and bagged according to size by mechanisms mounted on the self-propelled chassis.
