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' (3.0, 3.7, 4.6m ) working widths, sizes are available up to 36' (11 m) 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" (33 cm), the 7000 Series Disk Harrow works the top 2-6"(5-16 cm) of soil with its 24"- or 26"- (61-66 cm) 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.
