Replacement Bush Hog Rotary Cutter Blades – Part Number 7556, 27''x3/4'' Rancher Supply Lawn Mower Blades and Compatible Rotary Replacement Blades for Brush Mowers (2 Blade Set)

What It Is

This is a 2-blade set of heavy-duty replacement blades for Bush Hog rotary cutters and compatible brush mowers. Designed for clearing thick grass, brush, and light saplings, these 27-inch by 3/4-inch blades fit medium-to-large rotary cutters commonly used on tractors or zero-turn brush mowers.

Fitment & Compatibility

• Measurements: Blades are 27 inches long, 3/4 inch wide (at the mounting hole area), and typically 1/4 inch thick. Confirm your existing blade length and width match exactly.
• Mounting Hole: Check that the center hole diameter and bolt pattern match your spindle. Common holes are 5/8” or 3/4”, but measure yours.
• OEM vs Aftermarket: This is an aftermarket replacement for Bush Hog part number 7556. It may also fit other brands (e.g., Land Pride, Rhino, Woods) if dimensions match—verify with your model’s manual or a same-brand reference.
• Deck/Model Fit: Not universal. Works on 5- to 7-foot rotary cutters, not residential lawn mowers. Check deck clearance (blade tip to deck edge) to avoid contact.

Key Things to Know

• Quality: Heat-treated steel with a hardened edge for durability against brush and occasional rocks. Not as thick as some OEM blades, but sufficient for typical farm or ranch use.
• Installation Difficulty: Moderate. You’ll need a socket set, torque wrench (recommended 80-100 ft-lbs), and a jack or blocks to lift the cutter safely. Always replace blades in pairs to maintain balance.
• Common Gotchas: These blades are heavier than standard lawn blades—ensure your spindle bearings and belt can handle the extra weight. Also, aftermarket blades may require slight grinding to fit some decks; check for clearance before tightening.
• Warranty: Typically 90-day limited against defects. No coverage for damage from impacts or misuse.

Should You Buy It

If you own a Bush Hog or compatible rotary cutter and need a budget-friendly aftermarket replacement that handles brush and heavy grass, this 2-blade set delivers solid value. It’s best for owners who can verify fitment and don’t mind occasional minor adjustments. For commercial daily use or extreme conditions, OEM blades may offer longer life.
