I would want to mulch and at times use the bagger without changing blades. Which blades would be better, without changing blades, the standard 3-in-1 blades or the high lift blades. Thanks

Thank you for visiting Lowe's website. If you want to mulch and use the bagger without changing blades, the 3-in-1 blades would be the better option for your needs. These blades are designed for mulching, bagging, and discharging grass clippings. While high lift blades are excellent for bagging because they create more lift to help propel clippings into the bag, they are less effective for mulching. We hope this helps.
