3PK Oregon 91-621 High Lift Blades for 48" Wright Stander 71440002, 71490001

What It Is

This is a set of three high-lift replacement blades (Oregon part 91-621) designed for 48-inch Wright Stander mowers with deck models 71440002 or 71490001. The high-lift profile increases airflow for superior grass clipping discharge and bagging performance, making them ideal for thick or wet grass.

Fitment & Compatibility

Before buying, confirm your Wright Stander has a 48-inch deck and check the model number on the deck sticker (not the serial number). These blades fit Wright Stander 71440002 and 71490001 decks only. Measure the blade length—must be 16.5 inches, with a 5-inch center hole and 5-point star drive pattern. Oregon 91-621 is a direct OEM replacement for Wright part 71440002/71490001 blades. Not compatible with other Wright models or 36/52/60-inch decks. Verify your spindle bolt size (typically 5/8-inch) and blade thickness (0.204 inches) to ensure proper fit.

Key Things to Buy

• Quality: Oregon blades are heat-treated and hardened for durability, but high-lift blades wear faster than standard or low-lift due to increased grass contact.
• Installation: Straightforward if you have a blade removal tool and torque wrench; tighten spindle bolts to 70-90 ft-lbs. Star drive pattern requires a specific socket (not standard hex).
• Gotchas: High-lift blades create more vibration on rough terrain and may clog in very dry, dusty conditions. Always replace all three blades together for balanced cutting.
• Check deck level: After installing, verify deck is level side-to-side and front-to-rear to avoid scalping or uneven cut.

Should You Buy It

If you own a 48-inch Wright Stander and need maximum bagging or discharge performance in heavy grass, these blades deliver. They’re a solid value at $45.25 compared to OEM Wright blades (often $60+). Not ideal for mulching or light-duty mowing—stick with standard lift for those jobs.
