Abstract
A seed delivery system for use in a seeding machine that removes seed from a seed meter by capturing seed therefrom. The delivery system moves seed down to a lower discharge point and accelerates seed horizontally rearward to a speed approximately equal to the forward travel speed of the machine such that the seed, when discharged has a low or zero horizontal velocity relative to the ground. The delivery system uses a brush belt to capture, move and accelerate the seed. By capturing the seed and moving it from the meter to the discharge, each seed is held in place relative to other seeds and the planter row unit. As a result, the seeds are isolated from row unit dynamics thereby maintaining seed spacing.
