8TEN LawnRAZOR Blade for MTD Cub Cadet ZT2 ZT3 60-Inch Deck Toothed 490-110-C188 (Toothed) 3 Pack

What It Is

The 8TEN LawnRAZOR Toothed Blade (part #490-110-C188) is a 3-pack of aftermarket mulching blades designed for 60-inch MTD and Cub Cadet ZT2/ZT3 zero-turn mowers. The toothed edge chews clippings finer for better mulching and nutrient return, ideal for users who want to reduce bagging.

Fitment & Compatibility

• Deck size: Confirmed for 60-inch decks only; will not fit 42-, 46-, 50-, or 54-inch models.
• Machine fit: MTD, Cub Cadet ZT2 (all variants), ZT3, and compatible with Troy-Bilt, Craftsman, and Roper 60-inch decks using the same spindle pattern.
• OEM cross: Direct replacement for Cub Cadet part #490-110-C188 and #490-110-C189.
• Measurements: 20.5 inches long, 2.5 inches wide, 0.25-inch center hole diameter with a 5-point star drive center hole. Verify your spindle’s hole shape before ordering—this is not a standard round hole blade.
• Check: Count your blade bolts. Many 60-inch MTD decks use a single bolt per blade; if your deck uses two bolts, this blade will not fit.

Key Things to Know

• Installation difficulty: Easy—remove one bolt per blade, swap, and torque to 70–80 ft-lbs. No special tools required beyond a socket wrench and a blade removal tool or block of wood.
• Quality: 8TEN LawnRAZOR blades are heat-treated, coated steel. They are sharp out of the box but may need balancing (included free with most kits). Expect 25–35 hours of use before significant dulling on normal grass.
• Common gotcha: The toothed design creates more lift than standard blades. On very thick, wet grass, it can cause clumping or leave windrows. Run at full throttle and avoid cutting more than 1/3 of blade height at a time.
• Noise: Toothed blades are louder than straight-edge blades—expect a slight whirring sound. Normal for this style.

Should You Buy It

Buy this if you own a 60-inch Cub Cadet ZT2/ZT3 and want a high-quality mulching upgrade that reduces bagging frequency. It’s a solid value at ~$18 per blade compared to OEM Cub Cadet blades (often $25+ each). Skip it if you mostly bag or cut wet, overgrown grass—stick with a standard lift blade instead.
