Replacement 72531-VH7-000 (Upper) & 72511-VH7-000 (Lower) Blades Kit, Compatible with 21" Cut Hon da HRX217, HRX217K1, HRX217K2 Lawn Mowers, 2 Blades

What It Is

This is a two-blade set (upper and lower) designed for the Honda HRX217 mower’s unique “Versamow” system, which allows you to switch between bagging, mulching, and discharging. It’s a direct aftermarket replacement for the OEM Honda blades.

Fitment & Compatibility

• Deck size: Only fits 21-inch cut Honda HRX217 models.
• Compatible models: HRX217, HRX217K1, HRX217K2 (check your model number on the deck sticker).
• OEM numbers: Replaces Honda parts 72531-VH7-000 (upper) and 72511-VH7-000 (lower). These are not cross-compatible with any other brand or Honda mower series.
• Measurement check: Each blade is roughly 21 inches long, with a 3-point star center hole and a 0.75-inch offset. Measure your old blades’ center hole shape and offset height to confirm.
• Gotcha: The upper and lower blades are different—you cannot swap them. The upper blade has a more pronounced offset.

Key Things to Know

• Quality: These are steel blades, not hardened like OEM Honda blades. Expect slightly shorter edge life, but they cut well for the price.
• Installation: Moderate difficulty. You’ll need a socket wrench and a blade removal tool (or a block of wood to jam the blade). Torque bolts to 30-35 ft-lbs. The blades are directional—install with the lift wings pointing up toward the deck.
• Common gotcha: The center hole can be tight on some spindles. Lightly file the hole if it doesn’t slide on easily. Do not force it.
• Balance: Check blade balance before installing—an unbalanced blade will vibrate and wear the spindle. Use a simple blade balancer.

Should You Buy It

If you have a Honda HRX217 and want a budget-friendly replacement that works for normal residential mowing (not commercial use), this set is a solid value. It won’t last as long as OEM, but for less than half the price, it gets the job done. Skip it if you need maximum durability for heavy, frequent mowing.
