The Central Commodity System (CCS) seed metering technology and the multi-crop seeding capabilities of the 1990 CCS John Deere air-drill is capable of seeding oats, barley, wheat, milo and soybeans into no-till conditions. The new drills are available in four working widths of 30, 36, 40 and 42.5 feet. They offer three different row spacings: the 15 inch row spacing model is available in a single rank design, and the 7.5 inch and 10 inch row spacing versions are dual rank machines.

The central-fill seed metering system is offered in two configurations: models up to 36 feet wide use a single 70 bushel hopper, while 40 and 42 foot models use a 100 bushel hopper. Both hoppers feature a large, single lid and are easier to fill than earlier versions.

The 1990 air-drills feature a new, high performance air and oscillating agitation system. This design provides greater agitation for small grain crops that are prone to bridging and plenty of air volume to bring consistent seed population to the meters. The air and metering systems also have more capacity. Larger venturi cups and larger primary hoses allow for higher seeding rates with new crops. The feed wheels used on the metering system are incredibly accurate so that the amount of seed going to any meter at any time has no more than a two percent variance from meter to meter, says the company.

The larger dual rank models also feature a SM500 blockage system that has optical blockage sensors on every seed opener and a monitor with an easy-to-read numeric display. The meter drive system on these models also can be ordered with an optional dual range sprocket for additional crops and higher metering rates.
