Impact of Selected Mechanical Properties of Sweetcorn Seed on the Level of Cutting it Off from the Cob Stem

Research results on the quality of work of a seed cutter for selected cultivars of sweetcorn were presented. Measurements were carried out at the rotational speed of a head of 1600 rot. min⁻¹ and a linear velocity of the cob conveyor of 0.31 m s⁻¹. A statistically significant relation between the degree of cutting the seed mass and the selected mechanical properties of grain were determined. Differences between cultivars at the level of approximately 43% for the force of perforation of the peri-carp F_p,
