- 3-IN-1 BLADE: Serves 3 purposes (mulching, bagging, and side discharging) at the same time. Featuring numerous curves that cuts and re-cuts grass to smaller pieces, and recycles them back into the soil as nutrients to promote healthy lawn growth. Additionally, its high-lift increases the bagging capacity by 50%.
- LOWER CLOGGING RISK: Strong airflow and finely shredded grass can reduce clogging around the blade and improve mowing efficiency.
- NOTICE: The cutting edges are painted to prevent rust and protect your hands during installation. The paint will wear off as you mow the grass.
