Replacement Bush Hog Rotary Cutter Blades – Part Number 7555, 24''x3/4'' Rancher Supply Blades and Compatible Rotary Replacement Blades for Brush Mowers (2 Blade Set)

What It Is

This is a set of two replacement rotary cutter blades designed for heavy-duty brush mowers and Bush Hog-style rotary cutters. Use them for clearing thick grass, saplings, and brush on tractors or zero-turn mowers equipped with a 24-inch blade deck.

Fitment & Compatibility

• Measure your current blade: Length must be exactly 24 inches, center hole diameter 3/4 inch (common for compact tractors and subcompact brush cutters).
• Check OEM part numbers: These replace Bush Hog part 7555 and many aftermarket equivalents (e.g., Rancher Supply, King Kutter, Howse). Cross-reference with your mower’s model and blade spec.
• Not universal: Will not fit decks requiring a 1-inch center hole or blades longer/shorter than 24 inches. Verify blade thickness matches your spindle’s clearance (these are 1/4-inch thick).
• Deck size: Designed for 4- to 6-foot rotary cutters using two blades per deck. Single-blade or offset decks may not be compatible.

Key Things to Know

• Material: Heat-treated, hardened steel for impact resistance—good for rocky or woody terrain, but avoid hitting large rocks or stumps to prevent chipping.
• Installation: Straightforward with basic tools (socket wrench, torque wrench). Use thread locker on bolts and torque to manufacturer spec (typically 90–110 ft-lb). Left-hand threads common on some spindles—check your manual.
• Balance: Aftermarket blades may need balancing out of the box. Lightly grind the heavy side if needed to reduce vibration.
• Common gotcha: The 3/4-inch hole fits most, but some Bush Hog models use a 7/8-inch hole. Measure before buying—returns on blades can be tricky due to shipping weight.

Should You Buy It

Buy these if you need a durable, affordable replacement for a 24-inch rotary cutter on a compact tractor or brush mower and your existing blades are worn, bent, or chipped. Skip if you have a different blade length, center hole size, or a brand requiring exact OEM fit (e.g., Land Pride, Woods). The 4.4-star rating and 160 reviews suggest reliable performance for light-to-medium brush work at a fair price.
