B411 Plus is the compact, powerful and versatile self-propelled trunk shaker for the mechanical harvesting of olives, almonds, pistachio and hanging fruit trees of medium trunk size grown on medium-high density. The machine can work with or without reverse umbrella. The umbrella case contains about 250 kg of fruits which can unloaded through a hydraulically operated trap door on the bottom of the case. The 4-wheel drive with the rear steering axle along with the small size give the machine agility in reduced spaces while the telescopic arm and the hydraulic adjustments of the double jaws, facilitate the tightening of the trunk and main branches.
