The EGO POWER+ 21″ Select Cut XP Self-Propelled Mower delivers 8.3 ft-lb of torque 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 mower and is ideal for weekly mulching, giving you the mulching quality you would 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 EGO Upper Blade is used in combination with the lower blade chosen to slice the grass into fine fragments; this greatly enhances cutting performance with all grass types. EGO’s Self-Propelled Touch Drive™ Technology comes from years of research and development. Touch Drive™ Technology puts complete control of the self-propelled 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™ XP harnesses the power of the industry’s most advanced 56 Volt 10.0 Ah ARC Lithium™ battery by delivering 75 minutes of cutting time on a single charge.
