Air seed drill CTA series

towedfoldingdepth control

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' (12.2 and 13.7 m) 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" (38 cm), 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. (111 kg) 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. 00 OR 00HD OPENERS The Great Plains CTA-4000 and CTA-4500 Air Drills are offered with either 00 or 00HD (shown) offset opener blades. 00 Series openers are 13½" in diameter and offset ¼" to aid in penetration. 00HD Series openers feature 15" blades and a full ½" offset to be more aggressive in tough conditions. They also feature heavy 4mm blades with a special “no-till” bevel to ensure maximum residue cutting and consistent penetration. ACTIVE WEIGHT TRANSFER Active hydraulic weight transfer maintains even, consistent penetration across the entire width of the implement. CONSTANT HYDRAULIC DOWN PRESSURE Active hydraulics optimize seed placement by keeping openers in uniform contact with soil. Down pressure is applied independently at both ends of the subframe, maximizing opener ground-hugging capabilities in uneven conditions.
