Grasscool 42 inch Mower Blades Replace John D-eere AM141034 for D110 D130 D105 D125 X300 Z225 LA135 Z235 42" Deck Zero Turn Lawn Tractor AM137327 AM141032

What It Is

This is a set of three 42-inch mower blades designed to replace OEM John Deere part numbers AM141034, AM137327, and AM141032. They fit select John Deere lawn tractors and zero-turn mowers with a 42-inch cutting deck, including D110, D130, D105, D125, X300, Z225, LA135, and Z235 models.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 42 inches from side to side. Check your owner’s manual or current blade part number against OEM numbers AM141034, AM137327, or AM141032. These are aftermarket replacements, not genuine John Deere, so verify blade length, center hole size (usually 5/8-inch), and thickness (typically 0.25-inch) match your originals. They are not compatible with 48-inch or 54-inch decks.

Key Things to Know

• Quality: Made from heat-treated steel for durability, but may not hold an edge as long as OEM premium blades. Expect good performance for residential use.
• Installation: Straightforward bolt-on replacement. Use a torque wrench to tighten blade bolts to 70-90 ft-lbs (check your manual). Lift the deck or block it safely before starting.
• Common Gotchas: These blades are not mulching or bagging-specific—they are standard lift blades. If you need a mulching or high-lift design, look for a dedicated set. Also, inspect your deck spindle for damage before installing new blades.
• Wear Check: Replace blades when nicked, bent, or dull. Running dull blades strains the engine and leaves uneven cuts.

Should You Buy It

If you own a compatible John Deere with a 42-inch deck and need a budget-friendly, well-rated replacement for basic residential mowing, this set is a solid choice. It’s not for commercial use or specialized cutting needs, but for regular lawn care at $30.88 with strong reviews, it offers good value.
