| Olives (Olea europaea L.) are one of the oldest trees grown in the world; they are planted with two purposes: table and oil olive production. The main problem of olive production is picking the fruits from the trees. Fruit removal is the main aim of vibratory fruit-harvesting machines used on fruit-bearing trees. The mechanical harvesting of fruit for oil production in olive tree orchards is generally accomplished by applying vibration to the tree?s trunk. This vibration is consequently transmitted to the branches, causing the fruit to detach. Olive fruits for table are mainly hand harvested when bark green in color and before physiological maturity is attained. Hand harvesting accounts for the grower?s main production costs. Mechanical harvesters must be developed for successful olive harvesting and optimum profits. The type of machinery available at present are Hook shakers held by hand, Rake harvesters with reciprocating tines and mounted on extensions either operated by electric or pneumatic but also held by hand, Trunk shakers mounted on tractors or self-propelled which are efficient and perform well when combined with nets or wrap-around catching frames. The performance of trunk shakers is better than the traditional method of collecting olives on a canvas laid manually under the tree, the fruit being detached by shakers or rod | |
