8TEN Deck Blade Belt Kit for Exmark QT22KA421 Toro TimeCutter MX 4260 SS 4235 ZS 4200S Quest 42 Inch

What It Is

This is a complete blade belt kit for 42-inch Exmark Quest and Toro TimeCutter/SS/ZS zero-turn mowers. It includes two high-lift blades and a drive belt, designed for one belt-and-blade replacement service on residential/commercial 42" decks.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Must be exactly 42 inches. Measure your deck’s cutting width.
• Model series: Fits Exmark Quest QT22KA421, Toro TimeCutter MX 4260, SS 4235, ZS 4200S, and Quest 42" models. Check your mower’s model number (stamped under seat or on frame).
• OEM vs aftermarket: 8TEN is an aftermarket kit. OEM part numbers for reference: Toro 117-2782 (belt) and 117-0220 (blades). This kit replaces those. Not for 50" or 54" decks.

Key Things to Know

• Blade type: High-lift blades—great for bagging and mulching, but may reduce lift on wet grass.
• Installation difficulty: Moderate. You’ll need a socket wrench and blade removal tool. Belt routing diagram included, but double-check tensioner pulley position.
• Common gotcha: The belt may be slightly tighter than OEM. If your deck has worn pulleys, consider replacing those too to avoid premature belt wear.
• Quality note: Blades are heat-treated steel, sharp out of box. Some users report belt life around 2-3 seasons vs OEM’s 3-4. Acceptable for the price.

Should You Buy It

Good if you need a budget-friendly one-stop refresh for your 42" Exmark Quest or Toro TimeCutter/SS/ZS. Not for commercial use or if you want OEM-grade belt longevity. Fine for homeowners doing seasonal maintenance.
