At LAMMA I had a close look at the Aitchison Grass Farmer drill, Vredo overseeder drill and various grass seed harrows with pneumatic seeder box attachment. Would like to hear what the pro's and con's of the the drills etc I have mentioned , when used for overseeding ,reseeding stony grass paddocks and field margins,some may have been sprayed off with glyphoshate some would still be being grazed. Thank you.
