6PK Oregon 91-620 Replacement Blades for 48" Wright Stander 71440002, 71490001

What It Is

These are a 6-pack of Oregon 91-620 replacement blades designed specifically for 48-inch Wright Stander mowers (models 71440002, 71490001). They are aftermarket replacements for OEM blades, intended for commercial-grade turf finishing and high-volume mowing.

Fitment & Compatibility

• Deck size: 48-inch Wright Stander only. Measure your deck width to confirm.
• Model numbers: Fits Wright Stander models 71440002 and 71490001. Check your mower’s serial plate.
• OEM cross-reference: Replaces OEM Wright part numbers 71440002 and 71490001. Verify your current blade’s part number.
• Measurements: Each blade is 16.25 inches long, 2.5 inches wide, with a 0.203-inch thickness and a 5/8-inch center hole. Measure your old blade to confirm these dimensions.
• Mounting hardware: Uses 5/8-inch center hole – ensure your spindle bolts match (typically 5/8-18 thread). Blades are sold without hardware; reuse or replace your bolts/nuts.

Key Things to Know

• Quality: Oregon is a trusted aftermarket brand. These are heat-treated, hardened steel – comparable to OEM in durability but often more affordable.
• Installation difficulty: Easy – requires a socket wrench and torque wrench. Torque spindle bolts to 70-90 ft-lbs. Always lift the deck or remove the blade with the spark plug disconnected.
• Common gotcha: Do not overtighten – can warp the blade or strip the bolt. Also, check blade balance after installation; Oregon blades are usually balanced, but verify with a balancer.
• Pack size: 6-pack covers a full set for a 48-inch deck with 3 blades plus 3 spares. If you only need one, this is overkill.

Should You Buy It

Buy if you own a 48-inch Wright Stander (71440002 or 71490001) and want a reliable, cost-effective aftermarket blade set for regular replacement. Avoid if you need a single blade, prefer OEM parts, or have a different deck size/model.
