UDC Parts 138497 193957 Lawn Mower Blades Replacement for Craftsman 38 Inch 532193957 Husqvarna 532138497 Poulan 532127842 127842 581116302 LT1238 LT19538 LTH18538 LTH1538 / High Lift Mulching 2 Pack

What It Is

This is a 2-pack of high-lift mulching blades designed for 38-inch cutting decks on select Craftsman, Husqvarna, and Poulan lawn tractors. They replace OEM part numbers 532193957, 532138497, 532127842, and 127842, and are intended to improve grass clipping lift and mulching action compared to standard blades.

Fitment & Compatibility

Before buying, confirm your mower has a 38-inch deck—this is the only deck size these blades fit. Check your blade’s part number against the list: 532193957, 532138497, 532127842, or 127842. Common compatible models include Craftsman LT1238, LT19538, LTH18538, LTH1538, and Husqvarna/Poulan tractors with 38-inch decks. Measure your existing blade: these are 1/2-inch center hole, 7/8-inch oval center hole, 20.5 inches long, 2.5 inches wide. They are aftermarket replacements, not OEM, but match OEM specs. Verify your spindle shape—these are for standard 5-point star or oval hole spindles.

Key Things to Know

• Quality: 4.6/5 stars from over 4,200 reviews—users report sharp out of box, good balance, and durable steel. Some note paint chips off quickly, but that doesn’t affect performance.
• Installation: Moderate difficulty. You’ll need a socket wrench and torque to 70-90 ft-lbs. Use a blade removal tool or block the blade to prevent spinning. Check blade orientation—the high-lift wing should face upward toward the deck.
• Common Gotchas: These are high-lift blades, so they create more suction. On wet or tall grass, they may bog the engine more than standard blades. They also wear faster in sandy or gritty conditions. Always sharpen before first use if you want optimal cut—factory edge is good but not perfect.
• Mulching vs. Bagging: Designed for mulching, but work well for bagging and side discharge on 38-inch decks. If you primarily bag, these are fine; if you strictly mulch, they excel.

Should You Buy It

Buy these if you own a 38-inch Craftsman, Husqvarna, or Poulan lawn tractor and want a solid, affordable mulching upgrade over OEM blades. They’re a great value for the price, with high lift that improves cut quality and bagging performance. Avoid if you need OEM-exact fitment or have a deck smaller than 38 inches—they won’t work.
