134149 Mower Blade for 42" Lawn Tractor, 532138971, 532127843, 532138498, 138971, 138498, 127843 High Lift Blades Replace for Poulan/Husqvarna, Compatible with Craftsman LT1000 LT2000, 2 Pack

What It Is

A 2-pack of 42-inch high-lift mower blades designed to replace OEM parts on Poulan, Husqvarna, Craftsman, and compatible 42-inch lawn tractor decks. High-lift blades create stronger vacuum airflow for better grass clipping discharge and bagging performance.

Fitment & Compatibility

• Deck size: 42-inch cutting deck only. Measure your blade length (center hole to tip) – it must be 21 inches from tip to tip (half that per side).
• OEM cross-references: 134149, 532138971, 532127843, 532138498, 138971, 138498, 127843. If your mower uses any of these part numbers, these blades fit.
• Brand compatibility: Poulan, Husqvarna, Craftsman (specifically LT1000, LT2000 series). Also fits many AYP, Murray, and Sears models with 42-inch decks.
• What to check: Measure your existing blade’s center hole diameter (should be 1 inch) and the distance between mounting holes if your deck uses a two-hole pattern. Confirm your spindle’s hole pattern matches.

Key Things to Know

• High-lift vs standard: These produce more suction, which improves bagging and side discharge but may reduce engine efficiency on mulching-only setups. Not ideal if you primarily mulch.
• Installation: Simple bolt-on with a 5/8-inch socket or wrench. Torque to 70-90 ft-lbs. Use thread locker on the blade bolt to prevent loosening.
• Sharpness: Come sharpened but not razor-sharp. You’ll need to sharpen after first few hours of use on tough grass.
• Balance: Always check blade balance after sharpening. Unbalanced blades cause vibration and spindle wear.

Should You Buy It

If you need replacement blades for a 42-inch Poulan, Husqvarna, or Craftsman tractor and want better bagging performance, this is a solid, affordable option. Not for mulching-focused users – stick with standard or low-lift blades for that. For the price, it’s a good value for most residential mowing.
