This paper describes the in-field transportation process of Fresh Fruit Bunches (ffb), carried out by three different Colombian oil palm plantations. The three of them use tractors and figure out their transportation systems in accordance with their plantation design, distance to the mill, labor availability and machinery requirements. The transportation cost of a ton of ffb was estimated for each plantation. It has been determined that the efficiency of a transportation system depends on two facts. The first one is the production of ffb per hectare. The second refers to the activities assigned to each worker that in some cases generate a bottleneck in the system.
