Craftsman CMXGZAM110136 42-Inch Bagging and Side Discharging Lawn Mower Blade Set AYP/HOP High Lift OE# 138498, Black

What It Is

The Craftsman CMXGZAM110136 is a set of three 42-inch high-lift lawn mower blades designed for bagging and side discharging on Craftsman, Husqvarna, AYP, and Poulan Pro tractors. These blades replace OEM part #138498 and are intended for 42-inch cutting decks.

Fitment & Compatibility

Before buying, verify your deck measures exactly 42 inches from spindle to spindle. These blades fit most Craftsman (LT1000/2000/3000 series), Husqvarna (YTH22V46, etc.), AYP, and Poulan Pro models with 42-inch decks using a center hole diameter of 1 inch and a 5-point star drive. Check your blade’s length (42 inches) and the number of blades (3). Cross-reference your model number with the OEM part #138498. Aftermarket sets may have slight thickness or hole variations—measure your old blade’s center hole and star pattern to confirm.

Key Things to Know

• High lift design: These blades create strong airflow for superior bagging and side discharge, but they require more engine power and may clog in wet grass.
• Installation difficulty: Moderate. You’ll need a socket wrench and possibly a blade removal tool. Always disconnect the spark plug and block the blade before loosening.
• Common gotcha: The set includes three blades, but some 42-inch decks use two—count your existing blades before ordering.
• Quality: Steel is durable but may dull faster than premium aftermarket options. Check for balance after installation.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or AYP tractor and prioritize excellent bagging performance over blade longevity, this set is a solid OEM-replacement choice. Avoid if your deck uses two blades or if you mow heavy, wet grass frequently—you’ll need more frequent sharpening.
