Black & Decker 20v Trimmer Review: How to Buy

Black & Decker 20v Trimmer

You will likely feel confused when approaching your purchase: you will find dozens of types of lawn trimmers on the market. There are professional and semi-professional machines available. 

Some brands and others but you must take into account two points of crucial importance in your decision: its reliability and its good value for money. In our Black and Decker 20v Trimmer review, we have covered an ultimate buying consideration for you so that, it will be easier for you to choose the best one.


It is the first point. Black & Decker Lawn and grass trimmers have prices that range between $ 80 and $ 150. The rest of the characteristics will be defined by this value. A good performance residential mower can be found for less than $ 100.

There is much good quality within the price range between $ 100 and $ 200. Below that price are manual push mowers (not self-propelled). 


The blades should always be metal and easy to remove and sharpen. Poor or poorly sharpened blades will make cutting much more difficult and, above all, they will damage the grass, because they will pull it out rather than cut it.

In this way, the lawn suffers and deteriorates. It is more exposed to diseases and recovers less vigorously each time.

Cutting Height

The mowing height refers to the height at which the trimmer can leave the grass with each pass. Ideally, the trimmer offers different levels adjustable with a lever. The greater the range and the greater the lever positions, the better. 

It is good that they allow grass cuttings at a maximum height greater than 7 centimeters. You should never mow a lawn more than 1/3 of its current height.

If we want to make it shorter, it is appropriate to do it gradually, in several separate sessions over several days, never exceeding that limit. The higher the range that the mower offers us, the easier it will be for us to comply with this measure that favors the health and strength of our lawn.

Trimmer Size/Width

black & decker trimmer height

The cutting width is usually between 30 and 50 centimeters. The higher it is, the less travel you will have to do to cover the entire garden. The smallest and lightest mowers will barely exceed 30 centimeters. 

In exchange, its weight will be less and its maneuverability greater. If you are going to be carried by a light person, it may not be wise to make a larger and heavier trimmer. 

Even if they are self-propelled (you don’t have to push them, you just have to steer them), you have to make turns, you have to pick them up, you have to clean them, all this is easier with a light mower.

Between 20 and 30 kg, it can be considered that the equipment is light and up to 45 kg is manageable. There is no quality equipment with less weight.


Power is important because the higher the better you can work in difficult gardens: coarser grass, weeds, too high grass, slopes. If the garden is simple, 2 kW should be enough. If not, at least 3 kW will be needed.

Possibility of Mulching

Mulching is the option of cutting the grass very fine with several cuts while floating inside the housing and dropping it onto the grass. It will serve as good quality compost.  Many trimmers that allow it.

Some even have a system that allows the proportion of cut grass that goes to the collection basket to be returned to the ground.

Black and Decker 20v Cordless Trimmer Review: Common Q&A

black & decker trimmer faq

Here we have listed top FAQs (Frequently Asked Questions) which will clear all your doubts related to Black & Decker trimmer.

Q. How does the manual trimmer work?

A. Manual type lawn trimmer operates with a helical blade drum-driven from the wheels by push. The cutting width ranges from 30 to 45 centimeters.

There are two types:

Friction Mower: The helical blades contact a blade located in the base, generating friction and a “scissor effect”. They rotate at a few revolutions and have a lot of maintenance. The blades tend to get out of adjustment with some ease, it is necessary to check the cut periodically. They also require annual maintenance sharpening.

Frictionless Mower: The blade drum does not generate friction. This allows them to rotate at higher revolutions and make a more precise cut with less effort and noise. The prices of these mowers are higher. They need less maintenance.

Q. For whom is this type of mower recommended?

A. Ideal if you meet the following:

  • You have a small garden (less than 200 square meters).
  • The surface is smooth and clean (free of stones and branches).
  • You are willing to mow the lawn frequently.

A. It depends. These machines are cheap, in general, so the first option we would consider would be to buy a new one. Especially since it will come factory adjusted and will allow you to trim the lawn without any adjustment for a few months.

Q. Swapping of a battery of my trimmer with another brand is possible?

A. We recommend do not to do this, it may cause damage to your trimmer. Also, it may affect the balance of your machine during operation which ultimately will lead to injury.

If you face any issues related to the battery, you should take it to the nearest dealer for repair or service. However, most problems occur due to batteries.

Lithium battery lasts for a longer time but many times, it can stop working in rare times. If you find any issue with the battery, and if under warranty, you can ask the manufacturer for the replacement.

Q. How does this machine work?

A. Trimmer has a cutting head that spins at high Revolutions Per Minute (RPM). Its head has 2-line ports that feed cutting lines into the cutting head at a particular length. Some machines feature edging functionality and dual cutting.

The trimmer receives the power source from the lithium-ion battery. The battery is rechargeable with a 5-years average servicing life.
