Shopping for a used disks to help you break up your ground? This guide highlights what to check, common wear factors, important model years and technology features, pricing ranges, and how Koenig Equipment ensures you get lasting value out of your next disk unit.

What to Check For and Common Wear Factors in Used Disks

  • Disk Blades: Measure blade diameter; original sizes usually 20–24". If blades are below 16" or show excessive chips, cracks, or heavy wear, they will need replacement.

  • Bearings & Bushings: Rotate disks and gang shafts—listen for grinding, wobbling, or excessive play that signals worn or seized bearings.

  • Gang Frames & Standards: Inspect main frame and standards for weld repairs, cracks, and rust—focus on high-stress pivot and hinge points.

  • Arbor Bolts & Spacers: Check arbor bolts for integrity and proper torque. Look for bent, broken, or missing spacers or bushings that distort disk gangs.

  • Adjustment Features: Test hydraulic or manual adjustments on gang angles and working depth. Ensure all mechanisms move freely and without binding.

  • Wheels & Hubs: Examine tires for dry rot, sidewall damage, and hub/bearing grease leaks.

  • Leveling & Hitch: Evaluate the hitch for bends, cracks, or poor welds, and confirm unit raises/lowers level across its working width.

Important Model Year Milestones for Used Disks

  • 2010s: Wider adoption of notched and heavier-duty high-residue blades—increasing mixing and cutting action for corn, soybean stubble, and no-till conditions.

  • 2020s: Hydraulic folding frames, greater working widths (up to 40+ ft), and easier transport for custom operations; depth and gang angle adjustments now offer quicker fine-tuning from the cab or side frame.

  • Recent Updates: Improved contaminant-resistant bearing assemblies and reinforced frame strength, added for modern high-speed vertical tillage and larger tractors.

Price Ranges and Common Wear Costs for Used Disks

Factors like age, hours, brand, and condition all influence resale value of used disks. Below is a general guide to price ranges for disks, prices below or above these ranges do not mean the product is improperly priced, as this is just a general guide.
  • Small Disks (8 to 14 ft.): For older small disk models in working condition typical pricing ranges from $2,500 to $7,500 with newer small disk models (less than 5 years old) and in very good shape range from $7,500 to $13,000. These small disk units are normally used for smaller operations or for specific field use.
  • Mid-Size Disks (15-25 ft.): For older mid size disk models in working condition typical pricing ranges from $10,000 to $27,000 with newer mid-size disk models (less than 5 years old) and in very good shape range from $28,000 to $49,000+. These mid-size disk units are normally used for operations that work multiple fields, with the larger units (25 ft.) being more common.
  • Large & High Speed Disks (25+ ft.): For older large and high speed disk models in working condition typical pricing ranges from $35,000 to $80,000 with newer large and high speed disk models disk models (less than 5 years old) and in very good shape range from $80,000 to $139,000+. These mid-size disk units are normally used for operations that work multiple fields, with the larger units (25 ft.) being more common.
  • Common Wear Factors and Costs: Replacement parts, such as replacing blades, bushings, bearings, or tires, can range between $500 to $5,000+, with larger units expecting a larger cost for wear components.
