Box of 100 Scoop Flail Mower Knives/Flail Mower Blades for Vrisimo, Rears & Alamo Flail Mowers

What It Is

This is a bulk pack of 100 scoop-style flail mower knives designed for heavy-duty cutting on tractor-mounted or pull-behind flail mowers. Typically used for pasture maintenance, brush clearing, and roadside mowing where a clean, mulched cut is needed.

Fitment & Compatibility

Before purchasing, verify three things:

• Mounting hole size and spacing: Measure the hole diameter (commonly 3/8" or 1/2") and center-to-center distance between holes on your existing knives. These knives must match exactly to fit your hanger brackets.
• Knife thickness and width: These are scoop-style blades, typically 4–5 inches long and 0.25–0.375 inches thick. Compare to your current blades—too thick may not swing freely, too thin may wear prematurely.
• Brand/model: Listed for Vrisimo, Rears, and Alamo flail mowers, but not all models within those brands. Check your mower’s manual or measure one existing knife. Aftermarket fitment varies—don’t assume universal compatibility.
• Deck size: These are for standard-width flail decks (typically 4–6 feet). Not intended for zero-turn or walk-behind flail mowers.

Key Things to Buy

• Quality: Made from hardened steel but not OEM-grade. Expect slightly shorter lifespan than factory knives, especially in rocky or abrasive conditions.
• Installation difficulty: Moderate. You’ll need a bench grinder to sharpen edges before mounting—they come unsharpened. A 1/2" impact wrench speeds up nut removal/installation.
• Common gotchas: Mixing these with OEM knives on the same rotor will cause balance issues and uneven wear. Replace all knives at once. Also, check that the retaining pins or bolts included (if any) match your mower’s hardware—these often require separate purchase.
• Cost per knife: At ~$2.50 each, it’s cheaper than buying OEM in small packs, but only if your mower uses this exact scoop style. Wrong shape will leave uncut strips.

Should You Buy It

Buy this pack if you own a Vrisimo, Rears, or Alamo flail mower with scoop-style knives, need a bulk refresh for a large deck or commercial use, and are comfortable with minor aftermarket adjustments (sharpening, verifying hole spacing). Skip it if you need a precise OEM fit, have a different knife shape (e.g., Y-blades or side-slicers), or only need a few replacements—smaller packs will waste less time and money.
