Abstract: An orchard harvester vehicle of the type adapted for supporting and transporting means for gripping and shaking trees is disclosed. The vehicle has a frame having three rectilinear legs fixedly connected at inner ends thereof. Each leg defines a longitudinal axis, which axes intersect at the point of interconnection of the inner leg ends in the shape of a "Y" and form three arcuate sectors subtending arcs which together form a full circle. An operator's cab in the first forward sector has a longitudinal axis which is laterally oblique to the line of general advance. An internal combustion motor is operably connected to hydraulic pumps in the second rearward sector. At least one hydraulic wheel motor drives at least one of three ground engaging and traversing wheels. A wheel is pivotally and rotationally mounted at an outer end of each leg for rotation about horizontal axes normal to the general line of advance.
