High-Lift Blade Performance

The Rotary 17225 uses a high-lift blade profile designed to increase airflow beneath the mower deck. Increased airflow can help lift grass before cutting and move clippings more efficiently toward the discharge opening or into a compatible grass collection system.

High-lift blades are commonly used when side discharging or bagging grass. They are not necessarily the best choice for every mulching application.

Will the Rotary 17225 Fit My Mower?

The Rotary 17225 may fit your mower when the original blade number, dimensions, center-hole shape, and blade count match.

For the most accurate fit, confirm that your mower’s parts manual lists MTD blade number 742P05086 or 742-05086. You should also compare the Rotary 17225 with the blade currently installed on your mower.

Do not order by mower brand or deck width alone. MTD and Cub Cadet may use different blades depending on the mower model, deck configuration, production year, and serial-number range.
