Dimple seeders create seed pockets in the soil with conical spikes, seed is then dropped into the created holes. Seed which is left of the top surface is then brushed in prior to a rear roller closing over the holes, trapping in the grass seed. This method of overseeding is ideal if a large area requires overseeding, however this may not be the most precise option. Dimple overseeding can be high density while ensuring surfaces can be corrected with minimal surface disturbance.

Disc overseeders create grooves in the soil before accurately dropping seed down ready for the rear roller to close the groove and protect the seed, ready for the germination process to begin. This precise method of overseeding helps protect seed from birds and wind, increasing the chances of a guaranteed good germination rate.
