John Deere Original Equipment Model LX266 Maintenance Kit + Mulching Blades, 42M Mower Deck

What It Is

This is a John Deere Original Equipment (OEM) maintenance kit specifically for the LX266 lawn tractor with a 42-inch Mower Deck (42M). It includes the essential service items (oil filter, spark plug, air filter, fuel filter) plus two mulching blades designed for the 42M deck, making it a one-box solution for a full tune-up and blade replacement.

Fitment & Compatibility

Before buying, confirm your mower is a John Deere LX266 with the 42M mower deck (42-inch cutting width). The kit will not fit LX266 models with a 48-inch deck (48M) or other LX series tractors (e.g., LX277, LX280). The blades are 42M-specific—check your current blade part number (likely AM137228 or AM141003) to verify match. This is OEM John Deere, not aftermarket, so fitment is guaranteed for the LX266/42M combination. Measure your deck width (42 inches edge-to-edge) and blade length (approx. 21 inches each) if unsure.

Key Things to Know

• Installation difficulty: Moderate. Changing the blades requires a socket wrench and possibly a blade removal tool. The oil filter and spark plug are straightforward but need basic mechanical skills.
• Blade orientation: Mulching blades have a curved, high-lift design. Install them with the cutting edge facing the direction of rotation (usually marked on the blade). Wrong orientation will reduce cut quality and risk damage.
• OEM vs aftermarket: This is genuine John Deere—costs more than generic kits but ensures perfect fit and durability. Aftermarket blades may be thinner or not match the deck’s balance.
• Maintenance schedule: Replace blades at least once per season or after 25 hours of use. The included filters and plug are standard for a 100-hour service interval.

Should You Buy It

If you own a John Deere LX266 with a 42M deck and want a hassle-free, all-in-one tune-up kit with OEM reliability, this is the right choice—especially if you prefer mulching over bagging or side-discharge. At $138.99, it’s a fair price for genuine parts, but consider aftermarket alternatives if you’re on a tight budget or your deck is not the 42M.
