3 Main Features of the DEWALT 40V

Dewalt 40v backpack blower review

There are various types of backpack leaf blowers on the market, each with different features. 

This Dewalt blower is characterized for the high-grade quality of its construction and its long-lasting durability. Due to its incredible brushless motor, the Dewalt has a top-of-the-scale operational efficiency, excellent air flow system, and it offers users precise control of the engine.

It is tested and trusted to deliver superb power, reaching that of a gas blower. Further bolstering its high performance, this blower is a hard-surface cleaner. This means that it is equally great for surface cleaning stairs, sidewalks, garages, truck beds, rain gutters, and other hard surfaces.

1) Dewalt Power

DEWALT DCBL590X1 40V Backpack Blower review

When gauging the power of any leaf blower, there are two items to concentrate on:

  • The air volume of the blower, which is referred to as the CFM. The CFM will ensure that they keep moving.
  • The speed with which it moves air from the tube, known as the MPH. This will get the leaves moving.

Though most manufacturers will classify the 450 CFM capacity of this unit as medium-duty, this unit has been tested and is trusted to withstand even heavy-duty usage. Moreover, it has a high capacity to pick up debris and easily dispose of them.

2) Performance

Most users report that this unit performs even better than expected as it offers users a directed power that is not found in some commercial units.

The blower can clear deep layers of Spanish moss, oak layers, and twigs within six ft., while loose leaves are disposed of from a distance of 10 ft. This kind of power is equivalent to most gas blowers on the market.

Amazingly, this blower can also be used to clear out gutters filled with leaves and soil.

Further impressing users is the blower’s exceptional ability to blow off the dirt from the driveway. 

Additionally, this blower has an oversized right-side air intake that can suck in a lot of air.

Note that this blower also has a belt drive with a gearing that contributes to its high performance. With a fully charged battery, you can expect a straight run time of 25 mins max before you need another charge.

Thus, it can be genuinely said that among cordless leaf blowers, this model stands out for its high performance.

3) Construction Quality

The Dewalt blowers stand out for compact construction, and the 40v model is no exception. Compared to other Lithium-ion models that we’ve researched, this model is more stout.

This is due to the frame support at its base, which protects the blower when it is placed on the ground. This stout frame keeps the blower impeller a little bit apart from the debris and dirt. Its brushless motor construction extends the durability of this model.

  • 20 minutes of full use before recharging is needed.
  • The product comes with a 3-year limited warranty and 1-year free service contract.

Pros & Cons
