(3) High Lift Mower Blades Fits Ferris Zero Turn Walk Behind 32" 48" Deck Replaces 5101986

What It Is

This set of three high-lift mower blades is designed for Ferris zero-turn walk-behind mowers with 32-inch or 48-inch cutting decks, replacing OEM part 5101986. The high-lift profile increases airflow for superior grass discharge and bagging performance, making it ideal for thick or wet grass conditions.

Fitment & Compatibility

Before buying, verify your deck size (32" or 48") and confirm your mower model uses a three-blade spindle configuration. These blades are aftermarket replacements for Ferris models such as the 32" and 48" walk-behind zero-turn units (check your owner’s manual for exact model numbers). Measure the blade length: OEM 5101986 blades are typically 16.5" long with a 1" center hole and a 0.25" thickness. Ensure your spindle bolts match the standard 5/8" diameter. Aftermarket blades may vary slightly in material hardness or balance—compare your old blade’s dimensions directly.

Key Things to Buy

• Quality: High-lift blades generate more lift but require more engine power; they may wear faster in sandy or rocky soil. Check for balanced edges before install.
• Installation: Easy swap—remove old bolts, clean spindle area, and torque to 40–60 ft-lbs. Use thread locker if bolts are loose. Always sharpen new blades before first use.
• Gotchas: High-lift blades can cause clumping in very dry or light grass; they’re best for mulching or bagging, not side-discharge in low-cut conditions. Ensure blade tips don’t contact deck housing—measure clearance after install.
• Deck fit: The 32" and 48" decks use different blade sets; this kit is specific to the 48" deck (three blades) or 32" deck (two blades, but sold as three—check quantity). Confirm your deck accepts three blades, not two.

Should You Buy It

If you own a Ferris walk-behind zero-turn with a 32" or 48" deck and need reliable, budget-friendly blades for heavy-duty bagging or tall grass, this set is a solid choice. It’s a direct OEM replacement at a lower price, but verify your deck size and blade count to avoid mismatch.
