Featuring large central-fill hoppers, Great Plains Air Drills increase efficiency by covering more acres in a day than a box drill of equal width. Delivering 40' and 45' of working width, the CTA-4000 and CTA-4500 provide high efficiency with minimal cost per acre.

Each of these implements comes equipped with either standard 00 Series openers or 00HD heavy-duty openers. The 00HD option features 15", 4mm-thick disc blades, along with a cast blade separator and full-length seed tube to accurately place seed. 00HD openers feature a 30% stronger spring, providing up to 245 lbs. of penetration force that allows for operation in minimum-till and light no-till conditions. An 18-position press wheel with T-handle depth control ensures accurate seeding depth and closing of the seed trench.
