Caltric 54" Deck Blade with Nut Compatible with John Deere 190C D170 LA150 LA175 E180 G110 S180

What It Is

The Caltric 54" Deck Blade with Nut is a 3-blade set designed for 54-inch John Deere lawn tractor decks, intended for standard residential mowing, mulching, and bagging on mid-to-large lawns.

Fitment & Compatibility

Before buying, verify three things: deck size (must be exactly 54 inches, not 48 or 60), model number (fits John Deere 190C, D170, LA150, LA175, E180, G110, S180 – check your tractor’s model sticker under the seat), and OEM cross-reference (replaces John Deere parts AM141624, AM142765, AM137384, and AM141610). Each blade measures 19.5 inches long with a 1-inch center hole and 2.5-inch blade-to-blade spacing. The included nut is a standard 5/8-inch hex. If your deck uses a different spindle or blade pattern (e.g., older LA models with a 7/8-inch hole), this set won’t fit.

Key Things to Buy

• Quality: Caltric blades are aftermarket, typically made of hardened steel. At this price, they’re a budget option – expect comparable durability to OEM for seasonal use, but not commercial-grade longevity.
• Installation: Easy to swap – remove the old blade nut (use a wrench or impact driver), replace the blade, and torque the new nut to 70-80 ft-lbs. No special tools needed beyond a jack or block to lift the deck safely.
• Common gotcha: The included nut may be slightly thinner than OEM; use a thread locker if your deck vibrates heavily. Also, check blade balance after installation – if the mower shakes, the set may be unbalanced.
• Compatibility trap: This set works for 54-inch decks only. The LA150/LA175 models sometimes had 42- or 48-inch decks – measure your deck before ordering.

Should You Buy It

If you need a quick, affordable replacement for a 54-inch John Deere deck and don’t require commercial-grade steel or perfect balance, this Caltric set is a solid value for the price. For heavy-duty use or if you prefer OEM fit and finish, stick with genuine John Deere blades.
