GP 300 M1

The GP 300 M1 Harrow is the ultimate machine for pasture maintenance, including seeding and reseeding of grass. Because of the unique combination of 12mm and 8mm spring tines, grass is optimally dethatched and weeded. The GP Series, in combination with a PS Series Pneumatic Seeder, will level, dethatch, weed, aerate, reseed, and ensure seed to soil contact... all in one pass.
