What It Is

This is a set of three 42-inch high-lift mower blades, sold with bolts and washers, designed to replace OEM blades on specific Husqvarna and Craftsman lawn tractors. High-lift blades create stronger upward airflow, improving grass clipping discharge and bagging performance, especially in tall or damp grass.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches wide. This set fits Husqvarna models YTH18542, YTA18542, YTH1842, and YTH22V42, as well as Craftsman tractors using 42-inch decks. It replaces OEM part numbers 134149, 422719, 532138971, and Ariens 21546095. Measure your existing blade’s center hole diameter (typically 1 inch), overall length (approx. 21 inches), and spindle hole pattern. The included bolts and washers are pre-sized for these models, but verify bolt thread pitch (usually 5/16-24) matches your spindles. If you have a different brand or deck size, cross-reference your model number with the listed OEM numbers.

Key Things to Know

• Quality: Aftermarket blades, but made from hardened steel. Durability is comparable to OEM, though some users report slightly faster wear in sandy or rocky soil.
• Installation: Easy with basic tools—use a socket wrench and torque bolts to 30-40 ft-lbs. The included hardware saves a trip to the hardware store, but check that washers are the correct outer diameter for your spindles.
• Gotcha: High-lift blades increase engine load slightly. If your tractor struggles on hills or in thick grass, you may need to mow at a slower ground speed or raise the deck height.
• Balance: Aftermarket blades can sometimes be slightly off-balance out of the box. Test by hanging the blade on a nail; if it tilts, file the heavy side until it balances.

Should You Buy It

If you own one of the listed Husqvarna or Craftsman 42-inch tractors and need reliable, budget-friendly high-lift blades for better bagging or side discharge, this set is a solid choice. It’s not ideal for mulching (high-lift blades don’t recut clippings well) or for machines with lower-horsepower engines that may bog down. For general mowing on flat terrain, the price and included hardware make it a good value.
