HRX217 Lawn Mower Blade Set, 21" MicroCut Twin Blade Set Compatible with HRX217K1-K4 Mowers, Upper & Lower Replacement Blades for Bagging & Mulching, Replace 72531-VH7-000 & 72511-VH7-000

What It Is

This is a 21-inch MicroCut twin blade set for Honda HRX217 lawn mowers, designed for both bagging and mulching. It includes an upper and lower replacement blade that work together to produce a finer cut and improve clippings dispersal.

Fitment & Compatibility

• Deck size: Fits 21-inch cutting decks only. Measure your deck width before ordering.
• Model match: Compatible with Honda HRX217K1, K2, K3, and K4 models. Check your mower’s model number (on the back or under the seat) to confirm.
• OEM vs aftermarket: This is an aftermarket set. OEM part numbers are 72531-VH7-000 (lower blade) and 72511-VH7-000 (upper blade). If your mower uses different OEM numbers, this set won’t fit.
• Measurements: Upper blade is roughly 18.6 inches long; lower blade is about 20.6 inches. Verify against your current blades.
• Hardware: Does not include bolts or washers. You’ll need to reuse or replace the mounting hardware separately.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or a block of wood to lock the blade). Allow 20–30 minutes.
• Sharpness out of box: Blades are sharp but may benefit from a quick touch-up with a file for best performance.
• Common gotcha: The upper and lower blades are different lengths and must be installed in the correct positions. Mixing them up will cause vibration and poor cutting.
• Durability: Made from heat-treated steel, but they will dull faster on sandy or rocky soil. Expect to sharpen or replace every 2–3 seasons with normal use.

Should You Buy It

Buy this set if you own a Honda HRX217K1–K4 and want a budget-friendly alternative to OEM blades that still delivers a clean, fine cut for bagging and mulching. Skip it if your mower is an older HRX217 model with different blade mounts, or if you need the OEM-specific hardware included.
