摘要：
A row unit (16) of a planter or seeding machine (10) comprises a seed delivery system (28) that removes the seed (56) from a seed meter (26) by capturing the seed (56) therefrom. The delivery system (28) then moves the seed (56) down to a lower discharge point (78) and accelerates the seed (56) such that the horizontally rearward component of its speed vector is approximately equal to the forward travel speed of the seeding machine (10) such that the seed (56), when discharged has a low or zero horizontal velocity relative to the ground. Rolling of the seed (56) in the trench is thus reduced. Furthermore, as the seed (56) only has a short drop from the outlet to the bottom of the seed trench, the seed (56) has little vertical speed to induce bounce. The delivery system (28) uses a brush belt (60) to capture, move and accelerate the seed (56). By capturing the seed (56) and moving it from the meter (26) to the discharge, the seed (56) is held in place relative to other seeds (56) and the planter row unit (16). As a result, the seeds (56) are isolated from row unit (16) dynamics thereby maintaining seed spacing.
