Riding Lawn Mower Blade Removal Tool with Lawn Mower Blade Sharpener and Balancer Replaces MTD 490-850-0005 Blade Removal Tool Cub Cadet 490-850-0005 Lawn Mower Blade Holder Removal Tool

What It Is

This is a 3-in-1 tool set that includes a blade removal tool (holds the blade while you loosen/tighten the bolt), a blade sharpener (file guide), and a blade balancer (cone-style). It’s designed for riding lawn mowers, zero-turn mowers, and tractors with standard spindle-mounted blades.

Fitment & Compatibility

• Direct replacement for MTD 490-850-0005 and Cub Cadet 490-850-0005 blade holder tools.
• Works with most MTD, Cub Cadet, Troy-Bilt, Yard Machines, and Craftsman riding mowers using a 1/2" or 5/8" blade bolt.
• Check your blade bolt size before buying—this tool fits common bolt sizes but won’t work with metric or odd-sized bolts.
• Deck size doesn’t matter—the tool fits any deck as long as the blade bolt is accessible.
• Blade sharpener works on blades up to ~22 inches long; the balancer handles blades up to ~24 inches.

Key Things to Know

• Not a universal fit for all brands—John Deere, Husqvarna, and Ariens often use different blade bolt sizes or shapes.
• Installation difficulty: Easy. No mechanical skill needed—just slide the holder under the blade to prevent spinning, then use a wrench on the bolt.
• Sharpener is basic—it’s a file guide, not a precision tool. Good for touch-ups, but won’t restore badly dulled or nicked blades.
• Balancer works well but the cone is plastic and can warp if dropped. Keep it clean for accurate balancing.
• Common gotcha: The holder may be too thick for some tight blade-to-deck clearances—test fit before applying torque.

Should You Buy It

If you have an MTD-family riding mower (Cub Cadet, Troy-Bilt, etc.) and want a cheap, all-in-one tool for basic blade maintenance, this is a solid value. It won’t replace professional sharpening gear, but for homeowners doing seasonal blade swaps, it’s simple and effective. Skip it if you need a heavy-duty shop tool or have a non-MTD brand with odd bolt sizes.
