Husqvarna Blade

The most reliable way to confirm compatibility is to check your mower's owner's manual for the part number or look for the part number stamped directly on your current blade. This specific blade is OEM part number 539113425; if that matches your manual, it is a guaranteed fit.

Genuine OEM blades are manufactured to the exact steel specifications and balance requirements of your original equipment. Using an OEM part ensures the blade fits perfectly, maintains factory-specified cutting performance, and prevents potential vibration issues that can occur with generic, non-standardized blades.

The length is critical for the safety and performance of your mower deck. Using a blade that is the wrong size can cause the mower to vibrate excessively, damage the spindle, or result in an uneven cut, which is why you must match the length exactly to your machine's requirements.

While it depends on your lawn size and terrain, most experts recommend replacing your blade once a year or every 50 hours of use. If you notice the tips of your grass looking frayed or brown rather than cleanly cut, it is a clear sign that your blade has dulled and needs replacement.

Yes, this blade arrives sharpened and balanced from the factory. You can install it directly onto your mower deck, though it is always good practice to double-check that the mounting hardware is clean and secure before tightening it down.
