The Worx Nitro 80V Cordless Self-Propelled Lawn Mower features IntelliCut smart technology inside the lawn mower’s motor. It automatically senses when grass conditions are higher and thicker. Instead of bogging down during these conditions, the lawn mower cutting capabilities speed up to cut more efficiently. On the other hand, when the grass conditions are less demanding, the lawn mower will utilize its lower setting to conserve battery runtime.
IntelliCut refers to the motor of the 80V self-propelled lawn mower changing “speed” to cut more efficiently. On the other hand, the variable speed control lever adjusts the self-propel speed, or pace, at which the lawn mower moves. While operating in more demanding grass conditions, put the lawn mower in a slower speed to provide the blades more time to cut within a given area.
No. The WORX POWER SHARE™ PRO batteries can be used on all existing WORX 20V MAX chargers (WA3742, WA3881, WA3764, WA3770, WA3884, WA3835).
No. The batteries require the same amount of charge-time as the standard WORX POWER SHARE™ batteries. However, due to the Cell-Cooling Technology in the POWER SHARE™ PRO batteries, they stay cooler, longer. As a result, less wait-time is needed before a battery can start charging, due to high temperature.
