What It Is

The 187256 high lift blades are replacement blades for select Husqvarna, Craftsman, Poulan, and Ariens lawn tractors. They are designed for mulching and bagging, creating increased airflow to lift grass clippings into the bag or discharge chute.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits 42-inch and 46-inch cutting decks (common on Husqvarna Z254, Craftsman LGT2554, LGT2654, LGTH2454). Measure your deck width to confirm.
• Blade length: 20.5 inches (center hole to tip). Check your existing blade length—if yours is 20.5", these fit. If shorter or longer, they won’t.
• Center hole: 5-point star or 5/8" round? These have a 5-point star center hole. Your spindle must match. If your deck uses a round hole, you’ll need a different blade.
• Cross-reference numbers: Compatible with OEM 187256, 532187256, 539112053, 187254, 532187254, and aftermarket 11180. Confirm your model number is in this list.
• Brands: Works on Husqvarna, Craftsman, Poulan, and Ariens with the above deck and spindle specs. Not universal—check your mower’s model number.

Key Things to Know

• High lift = more power draw: These blades create strong suction, which can strain smaller engines (under 20 HP) or cause bogging in thick, wet grass. Use at full throttle.
• Installation: Requires a torque wrench (40-50 ft-lbs) and a blade removal tool or block of wood to hold the blade. Reverse-thread on some models—check your spindle.
• Sharpening: High lift blades dull faster than standard blades due to increased air resistance. Sharpen every 10-15 hours for best lift.
• Common gotcha: If your deck has a discharge chute plug or bagger, high lift blades improve performance. If you side-discharge only, they may throw clippings farther—consider standard lift blades instead.

Should You Buy It

Buy these if you have a 42" or 46" Husqvarna/Craftsman/Poulan/Ariens tractor with a 5-point star spindle, you bag or mulch frequently, and your engine is at least 20 HP. Skip them if you side-discharge exclusively or have a smaller engine—standard lift blades will work better and last longer.
