8TEN Blade Belt Kit for John Deere L100 L105 L107 L108 L110 L111 L118 Scotts L1742 42 Inch Deck GY20567 GX20072

What It Is

This is a complete blade belt kit for 42-inch cutting decks on select John Deere L-Series lawn tractors and the Scotts L1742. It includes the two OEM-style blades and the drive belt needed for belt replacement service.

Fitment & Compatibility

Check your deck size first – this kit is only for 42-inch decks. It fits John Deere models L100, L105, L107, L108, L110, L111, L118, and the Scotts L1742. The OEM part numbers cross to GY20567 (belt) and GX20072 (blades). If your deck is 38-inch or 48-inch, this kit won’t work. Measure your blade length (should be about 21 inches) and belt length (roughly 96.5 inches) to confirm. Aftermarket kit, not John Deere branded.

Key Things to Know

• Blade quality is decent – 8TEN blades are heat-treated and sharpened, but may not last as long as OEM John Deere blades in heavy or rocky conditions.
• Installation is straightforward – you’ll need a socket wrench and a blade removal tool (or block the blade). The belt routing is standard for 42-inch decks; take a photo before removing the old belt.
• Common gotcha – the belt tensioner can be stiff. Use a breaker bar or ratchet strap to relieve tension when installing the new belt.
• Check for deck damage – if your old belt snapped, inspect the idler pulleys and spindle bearings for wear before installing the new kit.

Should You Buy It

If you have a 42-inch deck on one of the listed John Deere or Scotts models and need a budget-friendly replacement for both blades and belt, this kit saves time and shipping costs compared to buying parts separately. It’s a solid value for light to medium-duty mowing. For heavy commercial use or if you want maximum blade longevity, stick with OEM parts.
