TerraTec Industries’ AggreScreed dozer grading attachment offers a stakeless process for spreading gravel on road grades. Skis on both ends of the attachment – a 16-foot blade that adjusts to 24 feet wide in two-foot increments – follow the established subgrade. TerraTec says AggreScreed can pay back its projected $65,000 cost by laying less than 10 miles of gravel road. The spreading blade can be attached and detached from a 125 to 250-horsepower crawler dozer in 15 to 20 minutes.
