Description
xHigh-strength JSXDNWYJ mulching blades replace John Deere GX22151/GY20850 to restore cutting performance on 42" decks.
If your John Deere lawn tractor’s 42" deck needs durable, mulching-capable blades, these aftermarket replacements from JSXDNWYJ are engineered to fit a wide range of D, LA, E, X and Z series models. Built to the same mounting pattern and overall dimensions as common OEM parts, the blades offer a balance of edge retention and shearing geometry for improved clippings dispersion and a cleaner finish when properly installed.
Will these blades fit my John Deere 42" mower deck?
Yes — the blades are manufactured to match the 7-point star center hole pattern and the length and thickness used on many 42" John Deere decks. They replace a number of OEM part numbers so they bolt on without modification for compatible machines.
- Replaces OEM/Genuine part references such as GX22151, GY20850, AM137328, AM137333, and AM141033
- Designed for 42" decks found on model lines: D100–D130 series and LA100–LA135 series
- Also fits models in the 100/110/120/130/140/300/300R/200 series listed by John Deere
- Uses the 7-point star center hole for direct mount compatibility
What are the blade dimensions and construction details?
These blades are produced to the dimensions required for consistent deck balance and cutting performance. The thickness and overall shape support mulching while resisting deformation under normal lawn use.
- Overall blade length: 21 7/16" (measured tip-to-tip)
- Cutting edge width: 2 3/4" for stable cutting surface
- Material thickness: 0.1875" (3/16") for strength and wear resistance
- Center: 7-point star hole to match John Deere mounting hubs
How do these blades affect mowing and mulching performance?
The blades are shaped to lift grass for a clean cut and to re-cut clippings for effective mulching, helping return finer clippings to the lawn. Proper installation and a sharp edge optimize airflow and mulching action.
- High-lift profile promotes even grass intake and chute flow
- Mulching geometry chops clippings into smaller pieces for quicker breakdown
- Balanced weight and thickness reduce vibration and wear on spindles
- Can be sharpened for extended life while retaining original shape
