- ... The fragile structure of the tomato fruit body leads to susceptibility to bruising caused by the aggressiveness of harvest and postharvest processes. Thus, grasping without damaging the tomato fruits is a key barrier to the replacement of manual labour by robotic harvesting. In this study, a four-element Burger model was used to express reversible viscoelastic behaviour and deformation characteris ...

- ... High levels of mechanical damage are a major obstacle for the mechanical harvesting of sugarcane. A chopping system for use in a sugarcane harvester was developed and tested. The three influencing factors studied were the rotational speed of chopping drums (RS), the overlapping length of upper and lower chopping blades (OL) and the bevel angle (BA). The quality of chopping included the percentage ...
