Yoursme 7556 Blade Replacement for Bush Hog Rotary Cutter Blades 27''x3/4'' Lawn Mower Blades and Compatible with Rotary Replacement Blades for Brush Mowers (2 Blade Set)

What It Is

The Yoursme 7556 is a 2-blade set designed for heavy-duty Bush Hog rotary cutters and brush mowers. These 27-inch blades with a 3/4-inch center hole handle thick grass, weeds, and light brush on tractors or zero-turn mowers.

Fitment & Compatibility

Before buying, check:

• Deck size: For 27-inch blades, your deck should be at least 54 inches wide (two blades) or 60+ inches (three blades). Measure your existing blade length from tip to tip.
• Center hole: 3/4-inch diameter. Confirm your spindle bolt size matches (commonly 5/8″ or 3/4″). If your bolt is 5/8″, these won’t fit.
• OEM vs aftermarket: Listed as compatible with many Bush Hog models (e.g., 270, 370, 470 series), but not OEM. Cross-reference your model number with Yoursme’s compatibility list.
• Thickness: Typically 0.25-inch thick. Verify your deck’s blade clearance—too thick can cause rubbing or poor cutting.
• Mounting hardware: These blades are sold as a set only. You may need separate lock washers, bolts, or spacers.

Key Things to Know

• Quality concerns: Rating is 3.7/5 with only 5 reviews. Some users report thinner steel than OEM blades, leading to faster wear or bending in rocky terrain.
• Installation difficulty: Moderate. You’ll need a torque wrench and jack stands (never rely on the mower deck lift). Tighten bolts to manufacturer specs (typically 70–90 ft-lbs).
• Balance: Aftermarket blades often require balancing before installation. Use a blade balancer to avoid vibration that damages spindles.
• No offset: These are straight blades (not offset or lift-style). They cut but don’t create strong suction for bagging or mulching—best for side-discharge or rough mowing.

Should You Buy It

Buy these only if you need a budget-friendly 27-inch blade set for light-to-medium brush mowing on an older Bush Hog or generic rotary cutter, and you’re comfortable checking fitment and balancing blades yourself. If you mow rocky, heavy brush daily or need OEM durability, spend more on genuine Bush Hog or high-carbon aftermarket blades (e.g., Oregon or Rotary).
