Generally, when you work for an extended period and your trimmer is older, it can overheat. Moreover, if there is an error in the battery, it can also gain temperature.

Uneven Cut

You have noticed that the Dewalt 20 V string trimmer is a handheld machine. You have to maneuver it by holding it on your lawn. As a consequence, your hand must be stable if you require an even finish on your property.

Moreover, the overall weight of this machine is nearly 8.5 lbs, which is hard to hold for an extended period. Due to the unstable holding, the result is also not satisfactory like the other types of mowing machines. And so, the weight of the head causes difficulties in maneuvering.

Spoiling Strings

One of the Dewalt 20v string trimmer problems that users have reported enormous problems regarding their mowing machines’ strings. The strings become loose or spoiled ultimately.

Some minor Dewalt 20v hedge trimmer problems include trimming unevenly, expressing less power, overheating battery, and many more.

The battery of the Dewalt 20 V is only capable of producing 5 Ah. It means the power you will get is around 5 amp for one hour. But, if you operate it on full power, you may only get service for one hour. So, it entirely depends on your utilization.

Vibration While Trimming

When your Dewalt 20v gets older, it is evident that it will start losing its features. Yet, you can take a chance to fix the vibration. Firstly, it occurs when your trimmer is old. The second reason may be if your trimmer’s line is unequal.

Again if your spool is harmed, it can create vibration. Another reason is the jam in the trimmer’s head.

Engine Does Not Start

There may be plenty of reasons behind this. But the majors are,

  • Break of internal wire.
  • Break of the circuit.
