Essential weed control in dry prairies. These blades cut weed roots under the soil surface without turning any soil over. This protects the soil from erosion and increases moisture retention. As with all tilling practices, getting these desirable results depends on good equipment. Weak, dull blades will churn soils. Wiese makes the most durable equipment on the market and we’re committed to making products that work right season after season. Made from quality, high-carbon steel and heat-treated they hold a sharp edge through miles of use. Like a knife sliding under a carpet; just as it should be.
