Great Plains CTA-4500

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. Low pivot points improve opener contact with the ground on terraces and field undulations.

DISTRIBUTION TOWERS
Dimpled distribution towers and transition cone divide seed equally for excellent seed distribution across the entire drill.

HYDRAULIC WEIGHT TRANSFER
Hydraulically transfer weight from the center section of the machine to the wings for even seeding depth across the entire drill.

INTEGRAL CONFIGURATION
The integrated cart-to-implement offers exceptional maneuverability when backing into a storage shed or the corners of a field.

LARGE CAPACITY ON DUAL-BIN CARTS
A split-bin design allows easy access when filling either the two 110 bu. steel hoppers or two 175 bu. poly hoppers. Fill one hopper with fertilizer and one with seed, or fill both with seed or both with fertilizer. An auger system will also empty the bins.

PRESS WHEEL OPTIONS
Single press wheel options include 3"x13" center rib, 3"x13" double rib, 4"x12" V-groove, 2"x13" smooth, or 3"x14" peak. Double press wheels include 1"x12" double V or 1.25"x13.5" wedge-style. Availability depends on model and/or row spacing; some styles require a special order.

UNIFORM SEED DISTRIBUTION
A single fan supplies air to a divided manifold where the star-wheel meters drop the seed into the airflow of each tower. The towers use a transition cone to uniformly divide the seed to individual rows. Full-length seed tubes complete the process, delivering seed to the bottom of the trench.

WHEEL TRACK REMOVAL
CTA implement models have an extra opener mounting position to lower the openers that are directly behind tractor tire tracks, ensuring proper seed placement and depth control.

OPTIONAL WEIGHT PACKAGES
Enhance penetration in harsh conditions. Std on HD models.

OPTIONAL INSIDE SCRAPERS
The cutting edge of tungsten carbide will outlast and outwear standard scrapers. Ideal for higher residue, moist conditions.

OPTIONAL SEED FIRMER
Keeps the seed in the bottom of the trench as it firms it into the soil.

OPTIONAL KNOCK-DOWN KIT (HD MODELS)
Combines a scraper and flexible deflector for sticky soil conditions.

OPTIONAL BLOCKAGE MONITOR
Monitors seed flow for optimum performance.
