490-850-0005 Lawn Mower Blade Removal Tool with Blade Balancer and Sharpener Replces MTD 490-850-0005, Troy Bilt 490-850-0005, Cub Cadet Blade Removal Tool 4908500005, Blade Removal Tool

What It Is

This 3-in-1 tool replaces OEM part 490-850-0005 and combines a blade removal wrench, a blade balancer, and a sharpening file. It’s designed for quick blade service on walk-behind mowers, zero-turn mowers, and tractors from MTD, Troy-Bilt, Cub Cadet, and other brands using that OEM part number.

Fitment & Compatibility

Before buying, confirm your mower uses a standard 7/8-inch or 15/16-inch blade bolt (the tool’s wrench fits both). It works with most MTD, Troy-Bilt, Cub Cadet, Yard-Man, and Bolens models that accept the 490-850-0005 OEM tool. Check your deck’s blade bolt size and center hole diameter – this tool won’t fit odd-sized bolts or blades with small center holes. It’s not for heavy-duty commercial decks with non-standard fasteners. If your blade has a 1-inch center hole or larger, verify the balancer cone fits before buying.

Key Things to Buy

• Quality: The included sharpener is basic – fine for touch-ups but won’t restore badly dulled or nicked blades. The wrench feels solid for homeowner use but may flex under high torque.
• Installation difficulty: Very easy – no special skills needed. Use the wrench to remove the blade bolt, then balance and sharpen on a flat surface. The balancer is magnetic, so keep it away from metal filings.
• Common gotcha: The balancer’s magnet is strong but can attract debris – clean it before each use. The sharpener file wears quickly; expect to replace it after 4-6 sharpenings.
• Warranty: No separate warranty – return through seller if defective. Not covered by Cub Cadet’s OEM parts warranty.

Should You Buy It

If you own one or two residential MTD-family mowers and want a cheap, compact tool for basic blade maintenance, this is a decent value at $20. It’s not for pros or those with heavily damaged blades – you’ll want a standalone sharpener and torque wrench for those. For casual homeowners who just need to keep blades cutting clean, it gets the job done without cluttering your shed.
