Great Plains Disk Harrow
The 7000 Series Disk Harrow from Great Plains delivers reliable, quality conventional tillage in a highly competitive disk harrow market. Now offered in 10', 12', and 15' working widths, sizes are available up to 36' to fit a variety of operations. The Disk Harrow's double-offset gang configuration remains one of the most effective methods for mechanically eliminating weeds, leveling rutted fields, and incorporating crop residue.
Featuring transport ground clearance of 13", the 7000 Series Disk Harrow works the top 2-6" of soil with its 24"- or 26"-diameter blades. In the field, a low-profile T-style hitch permits a tighter turning radius. On larger units, the outside wings are equipped with hydraulic gauge wheels that actively raise and lower with the main lift wheels.
This “grease-zerk-free” machine reduces maintenance time and costs with its maintenance-free bearings and pivot points. Additionally, the Disk Harrow’s heavy, ductile cast spools place weight “in” the gang, ensuring reliability of the C-shanks and bearings. For quick, easy maintenance, arbor bolt nuts are conveniently located on each end of the gang.
Additionally, exclusive SpeedBlades™ are optional on all Disk Harrow models. These low-concavity, serrated blades aggressively power through heavy residue, turning 5% faster than competitive notched blades. Plus, SpeedBlades are self-sharpening for longer blade life.
Engineered for easy transportation, reliable field performance, and minimal maintenance, the 7000 Series Disk Harrow is ready to take on all conventional tillage contenders and deliver superior results.

These 360° self-aligning bearings are never sideloaded. A six-lip seal on each side locks in grease and prevents contamination, which reduces maintenance time and extends the life of the bearings. |
|
Offset C-shanks cushion the gangs and protect the unit. The offset design also maximizes the clearance between the disc blades to help prevent plugging. |
|
Standard scrapers are spring loaded; quickly make them rigid by tightening a bolt. |
|
With a 5% faster turning speed than regular concavity blades, the exclusive SpeedBlade™ aggressively powers through heavy residue and thoroughly mixes soil at higher speeds without ridging. This self-sharpening serrated blade works like a regular notched blade, but its shallower blade cutout allows for shallower working depth. Unlike competitive blades, the low-concavity SpeedBlade stays sharper longer and maintains its shape as it wears. With more blade surface, the SpeedBlade wears better and last longer than blades with larger notches. |

Change the depth of the entire machine from one central location. |
|
All transport tires are radial tires and carry loads at 73 psi. Units also feature 8-bolt hubs on center and wings, with up to 8000-pound capacity for improved reliability. |
|
Transport clearance of 13" allows for 24" or 26" diameter blade options, and a low-profile, t-style hitch tightens the turning radius in the field. Hydraulic gauge wheels, which actively raise and lower with main lift wheels, have also been added to the outside wings on larger units. |
|
Stronger 4" x 6" gang bars have polygon bushings and hardened pins for greaseless hinge points. Four bolt attachment plates and cradle gussets relieve stress on gang tubes. |
|
Front gauge wheels adjust manually on 23', 26', and 30' models and hydraulically on 29', 33', and 36' models. Hydraulic gauge wheels prevent gouging and wing hop. |
|
On 3-section models, hydraulic fore-and-aft leveling simplifies field adjustments to create a smooth finish in any soil condition. |
|
Our heavy, ductile cast spools each weigh 23.55 lbs., while welded spools used by competitors weigh only 11.01 lbs. each. Putting weight “in” the gang versus “over” the gang increases reliability in the C-shank and bearings. Nuts on each end of the disk gangs provide easy, quick maintenance. |
|
Design ensures complete center cutout and eliminates the need for a middle breaker. |

Equip your disk harrow with a choice of disc blades. Click on the photo to view all options (from left): 22" or 24" SpeedBlades; 22" 6-gauge; 22" .25" rollable; 24" 6-gauge; 24" .25" rollable; 26" .25" non-rollable; or 26" .25" notched. SpeedBlades turn 5% faster than conventional smooth discs. |
