8TEN LawnRAZOR high-lift mower blades for Husqvarna 42" deck 3-pack — 5-point star fit, OEM 539112078 replacement

These are 8TEN LawnRAZOR high-lift replacement blades, a 3-pack engineered to fit 42-inch Husqvarna decks with the 5-point star center hole (OEM 539112078).

If your mower needs fresh cutting edges that match original specifications, this 8TEN LawnRAZOR set is sized and shaped to work with many Husqvarna and compatible zero-turn and garden tractor models that use a 42" deck. Each blade matches the factory length, width, thickness and five-point star mounting pattern so installation is straightforward, and the high-lift profile helps move clippings into the deck’s discharge or bagging system for cleaner pickup.

Which machines will these blades fit?

The 8TEN LawnRAZOR blades are designed to replace Husqvarna OEM part 539112078 and fit a range of 42" deck models from Husqvarna, Dixon, Kees and similar brands. Confirm your deck size and center hole pattern before ordering to ensure compatibility.

• Direct fit for Husqvarna models such as YT42XLS, YTH2242, RZ4222 series and many YT/YTH variants
• Compatible with Dixon SpeedZTR 42 models (part references 966657602, 966657701)
• Compatible with Kees ZEK42200 42" decks
• Designed for a five-point star center hole—check your spindle bolt pattern

What are the blade dimensions and mounting details?

Each blade is built to match the dimensional profile used by the referenced OEM part, so it sits and clears correctly inside a 42" mower deck. The five-point star center ensures the blade lines up with the spindle assembly used on these tractors.

• Length: 14 5/8" — matches the 42" deck blade length requirements
• Width: 2 1/2" and thickness: 0.197" for proper rigidity
• Center mounting: five-point star hole for direct spindle fit
• Sold as a three-blade set to replace all deck blades at once

How does the high-lift profile affect cutting and bagging?

The high-lift shape creates increased airflow under the deck to lift grass blades vertically before the cut and to carry clippings toward the chute, improving bagging and discharge in many setups. It can also help with mulching when used in a compatible deck, but mower setup and grass conditions influence results.

• High-lift curvature boosts suction for better bag filling and discharge
• Sharp leading edges give a cleaner cut when blades are maintained
• Properly balanced blades reduce vibration and wear on the spindle
• Replacement as a matched set helps ensure even cutting height across the deck

Who is this for? If you own a Husqvarna lawn tractor or compatible zero-turn with a 42" deck that uses the five-point star mounting pattern and you need factory-spec, high-lift replacements, this 8TEN LawnRAZOR three-pack is intended for routine maintenance, end-of-season blade refreshes, or whenever uneven cutting, tearing, or poor bagging indicates worn edges. Mechanically inclined DIYers and professional landscapers who prefer swapping all deck blades at once will appreciate the matched dimensions and compatibility list. Double-check your deck model and spindle bolt pattern to confirm this set matches your equipment before purchase.
