Performance of disks and rings for seeders subjected to increasing temperatures

Abstract

Abstract The objective of this work was to evaluate the effect of temperature on disks and rings for seeders and the consequences for the performance of seed distribution. The treatments consisted of the heating of three types of disks and rings for seeders at 30, 40, 50, 60, 70, 80, 90, and 100°C, with four replicates. The evaluated variables were: fitting to the base of the seeder, thickness, diameter, and quality of seed distribution (failed, multiple, and acceptable spacings). There is no significant deformation in the disks and rings for the analyzed variables, and the performance of the longitudinal seed distribution is maintained at all temperatures.
