IntelliCut™ is a smart technology inside the mower’s motor. It automatically senses when grass conditions are higher and thicker. Instead of getting bogged down by these conditions, the mower automatically speeds up to cut more efficiently. When the grass conditions are less demanding, the lawn mower will adjust to its lower setting to conserve batter power and extend run time.
The mower has a single lever to switch between bagging, mulching, and side discharge modes. Unlike most conventional mowers, the WP773 also features an integrated mulch plug. Instead of searching for a separate plug when you want to mulch, simply operate the integrated plug with an ultra-convenient onboard lever.
The tool is backed by a 5-Year Warranty. The batteries are backed by a 3-Year Warranty.
