What the 4511 Disk Ripper is used for

The 4511 is used for primary tillage in crop residue, especially when a farm wants disc cutting and shank tillage in one pass. The front discs cut residue, the shanks loosen and mix soil, and the rear discs help level the disturbed soil. A lighter spring pass may still be used where a finer seedbed is needed.

Why the Sunflower 4511 Disk Ripper stands out

The close 15 in shank spacing gives more complete tillage than widely spaced ripper designs. Front and rear disc sections improve residue handling and surface leveling around the chisel shanks.

Buying a used Sunflower 4511 Disk Ripper

Check shank trip mechanisms, points, twisted shovels, and shank standards for wear or damage. Inspect front and rear disc blades, bearings, gang bolts, and scrapers. Test hydraulic lift and depth control, then inspect tires, hubs, and the frame for cracks around disc and shank mounts.
