Buying Guide

Whether you are buying machinery for your kitchen, bath, drawing room or your yard, it is never about what you like or what appeals more. It is always about how helpful a product is and how safer it is especially when you buy lawn equipment. We have discussed some of the important factors below that will help you figure out what is best for you.

Source of power

Electric corded trimmers: The electric corded trimmers are lightweight and easy to handle. They are eco-friendly and emit no harmful gases. They do not make a noise and their sound is tolerable.  They generally require low maintenance and are available at cheaper prices. Corded string trimmers are usually not good for the big yards as they are not mobile due to the limited reach of an extension cord.

Electric cordless trimmers:  The electric cordless trimmers are a very popular type of trimmers. They are also lightweight, eco-friendly and low-maintenance products like corded trimmers. Unlike corded trimmers, they are more mobile but supply a limited runtime.

Gas-powered string trimmers: The gas-powered trimmers are more powerful than electric trimmers and are built for tough jobs. Most of the commercial or professional trimmers are gas-powered. They are expensive and not eco-friendly due to the emission of harmful gases.

Cutting Width/Cutting Diameter/Cutting Path

The cutting width or cutting diameter of a trimmer is an important factor that should be considered when you are buying a trimmer. If you own a small yard with too-tight spaces and corners, a trimmer with a small diameter will work best and will be available at a comparatively low price.


String trimmers come with different types of shafts which are as follows.

Straight shaft: Straight shafts are usually longer and they provide a more comfortable experience. They can be extended to the tight spaces easily and can even reach underneath the yard objects for trimming. String trimmers with straight shaft are sturdy and more attachment capable.

Curved Shaft: Trimmers with curved shafts are usually lightweight and cheaper than their counterparts with straight shafts. Due to the short length and nicely curved shape, they are more manoeuvrable in tight spaces. The curved shafts are usually not attachment capable and they are not as reliable as straight shafts.

Telescopic shaft:  String trimmers with telescopic shaft provide a comfortable experience you may adjust the height according to what suits your own height. Telescopic shafts work like the shaft of an umbrella than can slide in or out easily.

Detachable Shaft: Some trimmers come with detachable shafts that can be detached when the job is done to make storage easy and compact.

Line feeding

The line feeding systems are different and vary. For your convenience, we have given the different types below.

Automatic Feeding: This type of feeding system requires no manual work. All you need to do is just load the line and start work. The spool of the trimmer will automatically feed the line when necessary. This type of feeding system may increase the usage of string as the automatic feed system is usually designed to extend the line to a certain length which can be more than needed.

Bump to feed: In this type of feeding, the operator gently bumps the head of the trimmer against the ground to advance the string. Unlike automatic feeding, it releases the string only when you feel like so.

Push Button Feeding: The third option work with a push of a button. Whenever you feel like your trimmer is not trimming down much of the grass, it might be getting short of the string. If your trimmer employs a push-button string feeding mechanism, you just need to push the button and you are good to go.

Are 4-cycle trimmers better?

4-cycle trimmers are better in many ways. They are more reliable and last longer. They produce optimal power with more torque to ensure better performance in tough conditions.

Are curved or straight shaft trimmers better?

Both the curved shaft and straight shaft have their own advantages and disadvantages. Some people find curved shaft better while others feel that straight shaft offers a more comfortable experience. So, it is completely up to you and the type of your yard. Please refer to the buying guide for a better understanding.
