Key specs explained for this dethatcher
Voltage: 48 V (2 x 24 V)
This tool combines two 24V batteries to create a 48V system. You get higher power than standard 20V or 24V units. This extra voltage helps the motor spin faster and handle thick thatch. If you have a dense lawn, this power level is useful. It matches the performance of many gas-powered dethatchers. You can use other 24V Greenworks tools with these batteries.
Motor Type: Brushless
A brushless motor has no carbon brushes to wear out. This design reduces friction and generates less heat. You will likely see longer motor life and better efficiency. The tool runs quieter and uses battery power more effectively. This is a practical upgrade over brushed motors. It means less maintenance for you over the years. The motor also delivers consistent power as the battery drains.
Battery Capacity: 2 x 4.0 Ah
The package includes two 4.0 Ah batteries. This capacity provides enough energy for typical residential dethatching jobs. You can swap batteries to keep working without waiting for a charge.
