Otherwise, the two models sport the same features, including: an advanced Terra Phase Brushless high-performance motor, a removable battery and a 21" 3-in-1 steel cutting deck.
The SP21HB's advanced Terra Phase Brushless high-performance motor is designed to provide a high degree of performance while consuming minimal battery life. Its removable battery allows for on- or off-board charging and typically lasts long enough to cut an average-sized lawn before dying. Meanwhile, the SP21HB's 21" 3-in-1 steel cutting deck allows for side discharge, rear discharge or mulch settings for optimal versatility.
