Product Description

New & Improved Disk

In response to customer feedback and continued market demand for quality conventional tillage implements, Great Plains has released its new and improved 7000 Series Disk Harrow. After enduring intense field tests over several tillage seasons, the new 7000 Series Disk is ready to take on all contenders in the highly-competitive disk harrow market.

Like its predecessor, the 7000 Series Disk Harrow delivers the reliability and performance Great Plains customers have come to expect. Its double offset gang configuration remains one of the most effective methods to mechanically eliminate weeds while re-leveling rutted fields.

Additionally, farmers will appreciate the time and money savings the Great Plains 7000 Series Disk Harrow delivers through its maintenance-free pivot points and bearings, resulting in an implement that is "grease zerk free."

Fall Tillage: How to Deal with Ruts

Before and After: Turbo-Max® Vertical Tillage Implement
November 11, 2014

A rainy fall harvest season has caused wet soil conditions and moderate to severe ruts in many fields across the country. These ruts must be fixed before spring planting. Fall tillage needs to eliminate the ruts to ensure a good, uniform seedbed in the spring.

Farmers should analyze the severity of the ruts, then choose the tillage tool that matches their specific field needs—in many cases, the solution may involve a two-pass system. Our full line of tillage equipment is designed to meet the needs of each operation and eliminate ruts in a variety of field conditions.
