JYLEYJ John Deere 42" Mulching Gator Blades GX22151 — 42-inch direct-fit, improved clipping circulation

These JYLEYJ GX22151 Gator-style blades are heavy-duty replacement mulching blades engineered to fit a wide range of John Deere 42" decks and restore efficient, even cutting and grass recycling.

If your mower’s factory blades are worn, bent, or simply not mulching effectively, the JYLEYJ GX22151 offers a direct-fit replacement designed to match the OEM mounting pattern and restore performance. Made to the same dimensional standards as the original equipment, these blades are intended for homeowners and pros who want consistent clippings distribution, improved cut quality, and compatibility with many John Deere riding mowers and zero-turn machines.

Which John Deere models will these blades fit?

These Gator blades are made to replace the original 42" blades on a wide selection of John Deere lawn tractors and zero-turn mowers. The mounting hole pattern and blade length mirror OEM specifications so installation is straightforward on compatible decks.

• Compatible with John Deere 42" residential decks: S100, S110, S120, S130, S220, S240 series
• Fits D100–D130 and many LT/LA series lawn tractors
• Also suitable for select X300/X100, E100/E120, Z225/Z235 and EZTrak models

How do these mulching blades improve mowing performance?

The blades are shaped to lift and finely chop grass, promoting faster decomposition of clippings back into the lawn. That produces a neater finish and helps return nutrients to turf without requiring a bagging attachment.

• Gator-style cutting edge enhances airflow for improved clipping circulation
• Sharp, re-profiled cutting surfaces produce finer clippings for quicker breakdown
• Balanced construction reduces vibration and helps extend spindle life

What are the dimensions, mounting details, and warranty?

Each blade measures approximately 21 3/8 inches in length and 2 3/4 inches in width with a precise seven-point star mounting pattern that matches the OEM hole layout. That ensures proper alignment and secure fastening to most 42" John Deere decks. JYLEYJ supports the product with a one-year quality guarantee and customer support for installation or performance questions.

• Blade length: 21 3/8"; width: 2 3/4"
• Seven-point star mounting pattern for direct replacement
• One-year quality guarantee and dedicated customer support

Are these blades easy to install and maintain?

Yes — because they match the OEM mounting pattern, installation is a simple swap using the original hardware and basic hand tools. Routine maintenance is minimal: keep the blades sharp, check for damage after collisions, and ensure proper torque on mounting bolts for safe operation.

• Direct-fit design allows simple replacement with factory bolts
• Sharpen as needed to maintain good cutting performance
• Inspect for cracks or bends after impact and replace if damaged
