Oregon 6PK 92-030 Blade for Exmark 52" Radius E-Series RAE708GEM52300

What It Is

This is a set of three Oregon 6PK 92-030 replacement blades designed for 52-inch Exmark Radius E-Series zero-turn mowers (model RAE708GEM52300). They are high-lift blades suited for bagging and side-discharge cutting of thick or tall grass.

Fitment & Compatibility

• Deck size: Must be exactly 52 inches. Will not fit 48" or 60" Exmark decks.
• Model check: Confirmed for Exmark Radius E-Series RAE708GEM52300. Verify your mower’s model number on the frame or under the seat—other Radius variants may use different blades.
• OEM vs aftermarket: Oregon is a reputable aftermarket brand. These replace OEM Exmark part numbers 103-0366, 103-0367, and 103-0368. They are not identical to OEM—measuring before buying is smart.
• Measurements: Each blade is 17.5 inches long, 2.25 inches wide, with a 0.25-inch center hole and a 1-inch diamond-shaped drive hole. Confirm your spindle pattern matches.

Key Things to Know

• Quality: Oregon blades are heat-treated and coated to resist rust and dulling. They typically last a full season with regular use.
• Installation: Moderate difficulty—you’ll need a socket wrench and a torque wrench (recommended 70-90 ft-lbs). Lift the deck safely and block it before starting.
• Common gotcha: The blades are sold as a set of three, but some users report slight imbalance out of the box. Balance them before installing to avoid vibration.
• Aftermarket note: These are not OEM, so the fit may be slightly tighter in the spindle hole. If you have older spindles, check for wear first.

Should You Buy It

Buy these if you own a 52" Exmark Radius E-Series RAE708GEM52300 and want a cost-effective, durable replacement for bagging or side-discharge. They’re a solid upgrade over worn OEM blades, but if you prefer a guaranteed exact fit, stick with Exmark-branded blades.
