8TEN LawnRAZOR Blade Set for Husqvarna LT LTH 1238 38 inch Deck 127842 138497 531307221 532127842 (Notched High Lift)

What It Is

This is a set of three notched high-lift blades designed for Husqvarna LT and LTH series tractors with a 38-inch cutting deck. They replace OEM part numbers 127842, 138497, 531307221, and 532127842, and are intended for mulching or bagging in heavy grass or leaf conditions.

Fitment & Compatibility

Before buying, confirm your mower has a 38-inch deck (measure deck width from outside to outside). This set fits Husqvarna LT1238, LTH1238, and similar models—check your owner’s manual or existing blade part number. The blades are 3/8-inch center hole with a 20.5-inch length and 2.5-inch width. They are not compatible with 42-inch or 46-inch decks. Verify your spindle pattern: these use a single center bolt (5/8-inch) and are not for offset or oval-hole spindles.

Key Things to Buy

• Quality: Made from heat-treated carbon steel with a hardened edge; reviews note they stay sharp longer than OEM blades in normal use.
• Installation difficulty: Easy—requires a socket wrench and a blade removal tool or block of wood to prevent spinning. Torque the center bolt to 70-80 ft-lbs.
• Common gotcha: High-lift blades increase air flow for better bagging but can cause more vibration if not balanced. Always balance after installation (use a blade balancer or nail in a wall).
• Fitment check: If your deck has a stamped “38” on the top, you’re likely good, but measure the blade length end to end—aftermarket sets can vary by 1/8 inch.

Should You Buy It

Buy this set if you have a Husqvarna 38-inch deck tractor and regularly bag or mulch thick grass or leaves. It’s a durable, well-reviewed upgrade over OEM blades at a lower price, but skip it if you only side-discharge on short, dry lawns—standard lift blades will be quieter and use less power.
