What is Weed Eater?

A weed eater, also known as string trimmer, is a machine used to cut grass and weeds. It uses a sturdy nylon string that cuts weed while it rotates. Weed eaters can work with electric or gas powered engines.

Gas powered weed eaters are the most efficient and powerful. They also provide greater freedom of movement because they don’t depend on a nearby outlet to operate. However, they’re quite noisy and emit polluting gases.

Gas powered weed eaters tend to collect too much dust inside the air filters. In addition, lubricant oil needs to be changed so frequently. So, the maintenance costs in these cases are higher in contrast to other models.

On the other hand, electric weed eaters are quieter and less polluting. Electric devices use brushless motors to work. These types of motors generate less friction between the rotor and the stator, preventing overheating and waste production. Therefore, electric motors need less maintenance than their gas powered counterparts.

Electric weed eaters can be wired or wireless. Wired models use a power cord plugged into an outlet. On the other hand, wireless models use rechargeable lithium batteries to operate.

Lithium batteries are very practical because they allow you to cut weed in remote areas, where outlets aren’t available. However, these batteries tend to discharge too quickly, providing up to 2 hours of continuous service.

Also, they take a long time to recharge and can explode if overheated or scratched. So, you must be careful when using a wireless weed eater.

Step by Step Guide to Mix Gas and Oil for Weed Eater

Mixing gas and oil to put a weed eater to work isn’t as complicated as it seems. You just need to follow a series of steps to get the job done. This is what you need to do:

  1. First of all, read the user manual. If you don’t have it, you can also find it on the official website of the product. While reading the instructions, verify that the product really requires the gas and the oil to be mixed. Newest models have oil tanks to automatically make the mix.
  2. Use a clean, sturdy container to make the mix. Never use a milk carton for this purpose. The walls and lid of the container must be thick enough to contain the fuel vapors.
  3. Also, make sure to use the appropriate gas type. Some low cost options generate too much waste when burned, reducing the lifespan of the motor.
  4. Only apply the kind of oil recommended by the manufacturer. Using something different may considerably reduce the engine performance.
  5. Then, mix the gas and the oil at the proper volume ratio. 40:1 and 50:1 are usually the most common mixing ratios used on weed eaters.
  6. Finally, fill the fuel tank with the mix, turn on the engine and get down to work.


As you can see, you need the proper oil-gas mix to get the most out of your cutting tool. To do it, you don’t need previous experience or fancy tools. Just carefully follow each step and everything will be fine.

Also remember to use a container with thick and sturdy walls to make the mix. In addition, only use top quality products for the best results.
