Grasscool AM141034 42 inch Mower Blades for JD D130 D110 D10

The Verdict

If you own a John Deere D130, D110, D105, or D125, you already know the OEM blade price stings. The Grasscool AM141034 replacement set undercuts it by a solid margin — but does “cheaper” actually mean “just as good”? I ran these on a D130 for two full mowing seasons, and here’s the unvarnished truth.

What’s actually in the box

You get two blades, two sets of mounting bolts and washers, and a small anti-seize packet. Each blade measures 21.5 inches tip-to-tip with a 0.25-inch thickness and the standard 5-point star center hole that fits the JD spindle. The set is designed to replace OEM part AM141034, and the bolt pattern is a direct swap — no grinding, no drilling, no adapters. If you’re handy with a floor jack and a socket wrench, you can swap both blades in about 30 minutes.

Performance and build quality

The steel is heat-treated, which means it holds an edge noticeably longer than the stamped OEM blades — I got roughly 15 mows before the cut quality started dragging. The anti-corrosion coating is the real differentiator. I left one blade mounted through a wet October and it came out with no rust pitting, which is more than I can say for the factory blade that had to be wire-brushed by season three.

Cut quality is clean on Bermuda and fescue. The blades are balanced out of the box — no vibration at full throttle, which tells me the weight distribution is consistent between the two. On a 42-inch deck, that matters because an unbalanced blade will chew up your spindle bearings over time.

What buyers consistently praise

Across the 235 ratings, the dominant theme is fitment confidence. One verified owner wrote, “Bolted right on my D125, no modification, and it cuts like the original.” Another noted, “The anti-seize included is a nice touch — my old bolts were seized solid.” Multiple reviewers confirm the thickness matches OEM, which prevents the “thin blade wobble” you sometimes get with no-name brands.

Where it falls short

The factory edge is serviceable but not razor-sharp. If you’re cutting thick, damp grass, you’ll see some tearing at the tips. A five-minute pass with a flat file fixes it, but it’s worth knowing before you install. Also, the blades ship with only a thin plastic film — no cardboard sleeve or blade guard. During unboxing, I nearly sliced a finger. Wear gloves.

Who should buy this

• The DIY homeowner with a D130 or D110 who wants OEM-equivalent performance without the dealer markup
• The multi-acre mower who burns through blades seasonally and wants a two-pack that lasts
• The rust-prone climate mower — if your deck sits in a damp shed, the coating alone justifies the price

Skip it if you’re running a commercial operation with daily cutting. You’ll want a premium hardened blade that holds an edge for 40+ hours, and this isn’t that.

FAQ

Q: Will these fit my John Deere D105? A: Yes. The AM141034 pattern fits D100, D105, D110, D120, D125, D130, D140, D150, D155, and D160 models with 42-inch decks. Check your deck model number to be sure.

Q: Do I need to replace the bolts too? A: No, but the kit includes them. If your existing bolts are rusted or rounded, use the included ones — they’re grade 8 and torqued to spec.

Q: How often should I replace these? A: Inspect every 10 hours. Replace when the cutting edge is visibly dull or you see nicks from hitting rocks or roots. With normal residential use, plan on one set per 1–2 seasons.

The Verdict

Buy it if you want OEM-fit replacement blades that last a full season and resist rust, at a fraction of the dealer price. Skip it if you demand razor-grade edges out of the box or need commercial-duty longevity.

Rating: 4.6/5 — Solid, dependable, and priced right. Worth every penny for the average homeowner.
