Introduction
The EGO POWER+ 21" Select Cut Self-Propelled Mower delivers performance that exceeds the power of gas. The Select Cut Multi-Blade Cutting System is equipped with three interchangeable lower blades: the Mulching Blade, High Lift Bagging Blade, and Extended Runtime Blade. The Mulching Blade comes installed on the lawn mower and is ideal for weekly mulching, giving you the mulching quality expected from a high-end gas lawn mower. The High Lift Bagging Blade provides extra suction ideal for bagging, leaving your yard free of clippings. The Extended Runtime Blade provides an optimal balance of cut quality and runtime for all around performance. All three blades can be used interchangeably based on your desired cut. The Upper Blade is used in combination with the lower blade chosen to slice the grass into fine fragments, greatly enhancing cutting performance with all grass types. EGO Touch Drive self-propelled technology puts complete control of the self-propel system in the palm of your hands by using pressure to engage the system. Easily control the variable speed with a dial positioned at your fingertips for safe and convenient operation. The Select Cut cordless lawn mower harnesses the power of the industry’s most advanced 56V ARC Lithium batteries to deliver up to 60 minutes of runtime on a single charge with the included 7.5Ah battery. Three-in-one functionality delivers your choice of mulching, side discharge, or bagging your grass clippings; an easy-access two-bushel grass collection bag is included. This electric lawn mower includes bright LED lights for added visibility when mowing at dawn or dusk, and it folds for compact storage between cuts. Experience Power Beyond Belief with the EGO POWER+ 21" Select Cut Self-Propelled Lawn Mower.
