When new seeding projects require erosion control, the Kasco Krimper locks straw mulch into the seedbed, protecting your investment until germination takes hold. The notched disc blades poke straw firmly into the seedbed without cutting it, preserving the mulch’s full erosion-control effectiveness. The result is anchored straw that stays put on ditch banks, waterways and sloped terrain — even in wind and rain. Built-in weight pans let you add ballast when extra down pressure is needed for tougher conditions or denser straw.
