These Grasscool mulching blades are designed to match the 7-point star mounting found on many John Deere models (E140, D140, D160 and related series). They combine a multi-function cutting profile with higher lift airflow to shred clippings finely and improve bagging capacity while minimizing deck clogging.\u003c\/p\u003e\n\n\u003ch3\u003eWhich machines and part numbers does this blade fit?\u003c\/h3\u003e\n\u003cp\u003eThese blades are intended for 48-inch John Deere decks and replace several factory numbers. Confirm your deck uses a 7-point star center hole before ordering; some decks use a circular mounting and need a different SKU.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCompatible models include E140, E150, E160, E170, D140, D150, D155, D160 and many L, LA, S, X and Z series lawn tractors and zero-turns.\u003c\/li\u003e\n  \u003cli\u003eCross-references: John Deere GX21784, GY20852, AM137757, AM141035.\u003c\/li\u003e\n  \u003cli\u003eIf your blade center is circular, seek part M145476 \/ GY20568 instead.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow are these blades shaped and what performance can I expect?\u003c\/h3\u003e\n\u003cp\u003eThe Grasscool blades are mulching-style with multiple curved surfaces to lift and recut grass clippings repeatedly. That design produces finer clippings for faster decomposition and feeds nutrients back into the lawn, while a higher lift profile increases the volume moved into a bag when needed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBlade size: 17-1\/8\" (435 mm) long, 2-3\/4\" (70 mm) wide, 5\/32\" (4 mm) thick.\u003c\/li\u003e\n  \u003cli\u003eLift height: 1-3\/16\" (30 mm) to improve bagging capacity and airflow.\u003c\/li\u003e\n  \u003cli\u003e3-in-1 capability: mulching, bagging, and side-discharge from the same blade.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these blades reduce clogging and improve cut quality?\u003c\/h3\u003e\n\u003cp\u003eYes — the combination of high-lift geometry and multiple cutting contours promotes stronger airflow under the deck and finer shredding. That lowers the chance of wet-clipping clogging and helps maintain even discharge when side-discharging or bagging.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFiner shredded clippings pass through deck chutes more readily, reducing blockages.\u003c\/li\u003e\n  \u003cli\u003eHigher lift moves clippings efficiently into collection systems for better bag fill.\u003c\/li\u003e\n  \u003cli\u003ePainted cutting edges resist rust during storage and handling (paint will wear with use).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat quality checks and durability tests do these blades undergo?\u003c\/h3\u003e\n\u003cp\u003eGrasscool subjects each blade design to a battery of mechanical and field tests to verify hardness, bend resistance, balance, chip resistance and real-world cutting performance. These quality controls help ensure consistent fit and long service life under normal mowing conditions.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHardness and V-bend assessments to confirm material strength and flexibility.\u003c\/li\u003e\n  \u003cli\u003eChip and balance tests to minimize vibration and edge failure.\u003c\/li\u003e\n  \u003cli\u003eField performance checks to validate cut quality and airflow behavior on decks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this is for: Lawn owners and groundskeepers who operate John Deere 48\" decks or compatible tractors and need a reliable, multi-function replacement blade. Choose this blade if your mower uses the 7-point star mounting pattern and you want improved mulching, stronger bagging capacity, and reduced deck clogging without changing blades between tasks. If your mower has a circular center hole, order the alternate circular-mount SKU instead.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How do I confirm this blade fits my mower?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Measure your blade length (17-1\/8\") and check the center hole: this blade uses a 7-point star mount for 48\" John Deere decks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use these blades for mulching and bagging?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
