3PK Oregon 92-029 Blade for Exmark 48" Radius E-Series RAE708GEM48300

What It Is

This is a set of three 20.5-inch high-lift mower blades (Oregon part 92-029) designed for 48-inch Exmark Radius E-Series zero-turn mowers, specifically the model RAE708GEM48300. The high-lift design improves grass discharge and bagging performance, making it ideal for thick or wet grass.

Fitment & Compatibility

• Deck size & blade length: Confirmed for 48-inch Exmark decks using three 20.5-inch blades. Measure your existing blade length—if it’s exactly 20.5 inches (center hole to tip), these will fit.
• Model check: Direct fit for Exmark Radius E-Series RAE708GEM48300. Also compatible with many other Exmark 48-inch decks using OEM part 1-523067, but verify your model’s blade part number before ordering.
• OEM vs aftermarket: Oregon is a reputable aftermarket brand; these blades match OEM specs but are not Exmark-branded. Check that your spindle hole diameter is 1 inch (center hole) and the drive hole pattern matches.
• Measurement tip: Measure your old blade’s thickness (typically 0.204–0.250 inches) and ensure the Oregon blade matches—too thick can cause spindle strain.

Key Things to Know

• Build quality: Oregon blades are heat-treated and hardened for durability, but some users report they dull faster than OEM Exmark blades in sandy or rocky soil.
• Installation: Straightforward—remove the old blade, install with the lift wing facing up toward the deck, and torque to 70–90 ft-lbs. Use a blade removal tool to prevent spinning.
• Balance check: Always balance new blades before install. Oregon blades are typically balanced from the factory, but verify with a blade balancer to avoid vibration and spindle damage.
• Common gotcha: The center hole may be slightly tighter than OEM on some units; if it doesn’t slide on easily, file lightly—do not force it.

Should You Buy It

Buy this if you need a cost-effective replacement for your Exmark Radius E-Series 48-inch deck and don’t mind slightly shorter blade life than OEM. It’s a solid choice for homeowners or light commercial use on standard turf. Skip it if you cut in heavy debris or need maximum longevity—OEM blades may last longer.
