AM141034 Lawn Mower High Lift Blade for 42 Inch Deck John Deere D105 D110 LT160 LA135 Z225 - Heavy Duty Blade Replaces AM141034 AM141032 M154062 AM137327 M154061-2 Pack

What It Is

This is a heavy-duty high-lift blade designed for 42-inch cutting decks on select John Deere lawn tractors and zero-turns. The raised wing profile creates stronger airflow to lift grass for a cleaner cut and better bagging, making it ideal for mulching or collecting leaves.

Fitment & Compatibility

Before buying, confirm your deck is exactly 42 inches (measured blade tip to tip). This 2-pack replaces OEM part numbers AM141034, AM141032, M154062, AM137327, and M154061. Fits John Deere models D105, D110, D125, D130, D140, D150, D155, D160, D170, LA135, LA140, LA145, LA150, LA155, LA165, LT133, LT150, LT155, LT160, LT166, LT170, LT180, LX172, LX173, LX176, LX178, LX186, LX188, LX277, Z225, Z245, Z235, Z425, Z445, Z465, and Z645. Always double-check your model’s deck part number—some 42-inch decks use different blade lengths or center hole sizes. Measure your current blade: length (approx. 21 inches), center hole diameter (usually 7/16” or 5/8”), and thickness (0.25” typical). Not for 48” or 54” decks.

Key Things to Know

• Quality: Made from heat-treated boron steel for durability; thicker than standard OEM blades (0.25” vs. 0.20”) but still balanced.
• Installation: Easy DIY swap—requires a socket wrench and blade removal tool. Torque blade bolts to 70-80 ft-lbs. Use threadlocker if bolts are worn.
• Common Gotchas: High-lift blades increase engine load and may reduce fuel efficiency. They also throw debris more aggressively—avoid gravel or loose dirt. Check blade bolt length; some aftermarket bolts are too short for these thicker blades.
• Performance: Best for bagging or mulching tall grass; not ideal for side-discharge on wet, heavy grass (clogging risk).

Should You Buy It

Buy this if you have a compatible 42-inch John Deere and want noticeably better bagging or mulching performance than standard blades. It’s a solid upgrade for leaf cleanup or frequent tall-grass cuts, but skip it if you only side-discharge on dry, short turf—standard blades are more efficient there.
