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 38 cm 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 tyres, hubs, and the frame for cracks around disc and shank mounts.
