Caltric 501124 501001 Cutter Blades & Bolts w/Nuts Compatible with King Kutter 5' Rotary Cutter

What It Is

This is a 3-blade set with mounting hardware (bolts and nuts) designed for King Kutter 5-foot rotary cutters, used for heavy-duty brush and grass mowing on tractors or zero-turn equipment.

Fitment & Compatibility

• Deck size: Fits 5’ (60") rotary cutters, not 4’ or 6’ models.
• Model check: Confirmed for King Kutter models like the 5’ RCR, XB, and standard brush cutters. Verify your specific model number against Caltric’s list.
• OEM cross: Replaces OEM part numbers 501124 (blade) and 501001 (hardware). Not an exact OEM clone—measurements may vary slightly.
• Measurements: Blade length is typically 23.25", width 3.25", thickness 0.25". Measure your old blades and bolt hole diameter (usually 0.625") before ordering.
• Hardware: Includes bolts and lock nuts—check thread size (usually 1/2" x 20) matches your spindle.

Key Things to Know

• Quality: Caltric blades are hardened steel, comparable to OEM but may wear faster on rocky or sandy soil. Inspect for warping upon delivery.
• Installation: Easy bolt-on swap; use a torque wrench (specs around 90-100 ft-lbs for the nuts). No blade sharpening needed before first use.
• Gotcha: Some users report the bolt holes are slightly off-center—you may need to file the hole or slot for a perfect fit on older spindles.
• Balance: Always check blade balance after mounting; an unbalanced set causes vibration and spindle damage.

Should You Buy It

If you need a budget-friendly, ready-to-install blade set for a King Kutter 5’ cutter and don’t mind a possible minor fitment tweak, this is a solid value. Skip it if you require exact OEM specs or run a commercial operation needing the longest possible blade life.
