The Ninja cover crop crimper is a simple and effective cover crop management tool! Crimping is a proven method of terminating specific cover crops, most notably rye, without the use of chemicals or tillage. The mat of biomatter created by the decaying cover crop limits weed pressure to your growing crop and provides nutrients to the soil and for your future crop. Ninja’s are offered in 3 point ridged and folding models ranging from 5’ up to 30’ crimping widths. New folding models offer narrow transport and flexible wing pivots for bettering contouring in uneven terrain.
