XHT 2 HI Lift Blades Compatible with John Deere AM137327 M154061 LA102 LA120 125 135 X300 X304 42"

What It Is

The XHT 2 HI Lift Blades are aftermarket replacements for 42-inch John Deere mower decks, designed to create a stronger vacuum for superior grass lift and bagging performance. They’re ideal for mulching or collecting leaves in residential or light commercial use.

Fitment & Compatibility

Before buying, confirm your John Deere deck is exactly 42 inches (measured blade tip to tip). These blades replace OEM part numbers AM137327 and M154061. Compatible models include LA102, LA120, 125, 135, X300, and X304, plus others with a 42-inch “Edge” or “Accel Deep” deck. Check your deck’s spindle hole size – these blades use a standard 1-inch center hole and a 5-point star drive pattern. Measure your existing blade’s length and width (these are 21 inches long, 2.5 inches wide). Aftermarket fitment is good, but verify blade thickness (0.203 inches) matches your spindle clearance.

Key Things to Know

• Installation is straightforward – just a single bolt per blade (usually 5/8-inch or 15/16-inch). Use a torque wrench to 45-55 ft-lbs and apply anti-seize to prevent rust.
• Hi-lift design improves bagging but increases engine load – expect slightly more vibration and power draw on wet grass. Not ideal for low-horsepower riders (under 15 HP) on thick turf.
• Balance and sharpness – XHT blades come pre-sharpened and balanced, but check for warping out of the box. Re-sharpening is easy with a file or grinder; replace if bent.
• Common gotcha – These blades are longer than standard low-lift blades; ensure your deck’s discharge chute doesn’t contact the blade tips. Test spin by hand after installation.

Should You Buy It

Yes, if you own a compatible 42-inch John Deere and prioritize bagging or leaf collection over a pristine cut on manicured lawns. The $40.52 price is fair for the lift performance, but skip them if you mainly mulch or have a low-horsepower mower – standard low-lift blades will be smoother and less taxing.
