Caltric 2 Blade Deck 38" Compatible With John Deere LT150 LT155 LT160 LT166 LT180 AM-141039 M-153118

What It Is

This is a set of two 38-inch replacement blades for John Deere lawn tractors. Designed for medium-duty residential mowing, it fits select Deere models with a 38-inch stamped deck.

Fitment & Compatibility

Before buying, verify your mower has a 38-inch deck (measure cutting width, not chassis). Compatible with John Deere models: LT150, LT155, LT160, LT166, LT180. This is an aftermarket blade set, not OEM John Deere, but it cross-references OEM part numbers AM-141039 and M-153118. Confirm your deck uses two blades (some 38" decks use three). Measure blade length: these are 15.5 inches long with a 1-inch center hole and 0.25-inch thickness. Check your spindle orientation—these are symmetrical and fit most standard 38" Deere spindles.

Key Things to Know

• Quality vs. OEM: Caltric blades are sharpened and balanced out of the box but may not hold an edge as long as OEM John Deere or high-carbon steel blades. Expect replacement every 10–15 hours of use.
• Installation: Easy swap—remove bolts, align blade with spindle, torque to 30-40 ft-lbs. Use a block of wood to prevent spindle rotation. No special tools required.
• Common gotcha: The included hardware (if any) may not match OEM. Re-use your original bolts and washers unless they’re worn. Check blade bolt torque after first 30 minutes of use.
• Deck fit: Ensure your deck isn’t warped or bent—these blades only fit properly on a true 38" deck. Measure old blade length to confirm.

Should You Buy It

If you own a compatible 38-inch John Deere LT-series and want a budget-friendly replacement for routine mowing, this Caltric set works. It’s not ideal for heavy commercial use or if you need OEM durability, but for residential lawns, it offers good value at $43. Skip it if you have a different deck size or need a 3-blade setup.
