We have a family farm with around 1800 acres of cotton. The pigweed was our most severe nuisance. After spending thousands of dollars on chopping, we decided to purchase the GrassWorks Weed Wiper. The Weed Wiper works great and usually with one wipe, the weeds are under control. We have started using it on turn rows also to keep the weeds for returning to the field. We found that for the applications we use it for, it paid for itself with the first year and is an excellent tool for our farming practices.
