The PowerCommand dial is an amazing feature that makes this weed eater a highly efficient power tool. You can use this device to get your job done more efficiently and much faster.

It allows you to shift between two modes of speed max power (8,500 RPM) and max runtime (6,500 RPM). While max power can help you deal with thick weeds with ease, max runtime enables you to save the battery life to help it run for a longer time.

The LST136W works well for moderate cutting of the lawn grasses and weeds, however it cannot be used to cut the thick bushes. The weed eater lasts for only 15 minutes on high power, and it can last for about 1 hour on medium power.

It is advisable that you use the low power for standard grass cutting and weed removal tasks. The tool consumes a lot of line and if you have a large sized yard, it will not last long enough to complete the job.


The Black & Decker LST136W allows you to cut with precision, which is good if you are working around small trees, or flowers. If you live in a city or suburban setting where you need to perform general-purpose trimming tasks to keep your garden well maintained, the LST136W is a good choice.
