Is there a certain speed we need to go when we crimp? By GrowingDeer, 06/02/2021 Filed under: Ask Grant, Food Plots ← Grant's Answers — Ask Grant There are lots of variables – maturity of the crop, roughness of the terrain, etc. Be sure the crimper doesn’t bounce. If it’s bouncing it won’t terminate all of the crop and will be a very tough ride. We usually crimp about 2-3 miles per hour.
