Straight Shaft Trimmer

Straight Shaft Trimmer

Most yards and lawns will also include a few other plants like trees and shrubbery. While these other plants help to beautify the yard they can also make grass cutting hard.

It is the need to reach under the trees and shrubbery when trimming grass that makes the straight shaft trimmer popular. And this is because the shaft is long and sturdy enough to make it easy to reach under low hanging trees and bushes.

The straight shaft trimmers are also more potent than the curved shaft ones due to the length of the shaft. These trimmers will be the best when you have a large property or have to clear heavy brush.

Straight shaft trimmer will also run blades, accommodate bigger head and also use a heavier line as they are powerful enough. All this will be hard to achieve when using most curved shaft trimmers.

These trimmer models are also more likely to last longer than the curved shaft ones because their drive cable will not have to flex as much. Also, they tend to vibrate less as they are heavier than the curved ones. The extra smoothness or reduced vibrations also make the parts last longer.


  • More powerful. Trimmers with a straight shaft will tend to provide more power than those with curved ones. And so they will be ideal for hea​​​​vy-duty trimming chores or when dealing with a large yard and dense brush.
  • Less vibration. Straight shaft trimmers will be heavier than the curved shafts ones, and this means that they will vibrate less and hence reducing user fatigue from extended periods of use. Also, less vibration will make the parts last longer, and so the straight shaft trimmers tend to be more durable than the curved shaft ones.
  • Versatile applications. Most straight shaft trimmers will come with interchangeable heads that makes them, more versatile and suitable for a variety of jobs. Since they can also accommodate blades and heavy lines, there is almost no trimming job that is too much for these trimmers.
  • Best for clearing hard to reach places. The straight shaft and its extra length make these trimmers ideal for trimming the hard to reach areas. Their design makes it easy to reach under overhanging tree branches, under low decking and also for clearing sharp corners.


  • More cumbersome. The straight shaft trimmer might be more powerful and versatile than the curved shaft ones, but they are also more cumbersome. And so they will be quite heavy to carry around for extended use, and this is more so for smaller persons.
  • Relatively expensive. When you compare the straight shaft trimmers to the curved ones, you will find that in most cases they tend to be pricier. Their versatility and more powerful performance mean that you have to pay more to own one. Many high-performing straight shaft trimmers will cost upwards of $200.​​​​

Curved Shaft Trimmer

Curved Shaft Trimmer

With the ever decreasing real estate spaces many homeowners now have small lawn and yards. And if this is the case for you a lightweight and affordable trimmer is always the best option.

The curved shaft trimmers are as lightweight as it can get and are always the best option for those with small yards.

And as the name suggests, the curved shaft trimmers are the type that will come with an arched drive cable. These trimmers also feature a shorter shaft than what you get on the straight shaft models.

Besides from their lightweight, the curved shaft trimmers are also easier to use than the straight shaft ones, and they will be an excellent choice for light trimming on small properties.

The design and shorter reach of the curved shaft trimmers are very suitable for people with small statures, and they will be more comfortable and easy to use for regular yard maintenance. However, the short shafts can be a significant shortcoming for taller individuals as they will have to lean forward a lot.


  • Relatively affordable. If cost is a significant concern for you, the curved shaft trimmer is a better option than the straight shaft ones. In most instances, they will be more affordable, and if you get a good model, it can perform almost everything that the expensive straight shaft ones can do. While the price will depend on the brand and model, on average, you will spend around $100 on these trimmers.
  • Lightweight and maneuverable. The lightweight curved shaft trimmers are simple and comfortable to handle and are also highly maneuverable. With these trimmers, you can get in and out of small places easily.
  • Best for small yards. Curved shaft trimmers are the best for working on small yards and lawns. Their style and weight make them perfect for your small property, and it will ensure that it is more efficient and easy to use.


  • Not blade capable. Unlike the straight shaft trimmer, the curved shaft will not run blades, and this is a significant shortcoming because it limits the things that you can use it to trim.
  • Tall users have to reach down. The short shaft on the curved shaft trimmers means that they might not be ideal for tall people because they will have to reach down a lot when using it. When trimming grass on large yards or using it for extended periods, this can cause excess fatigue.

The Bottom Line

The size of your yard and budget are always important factors to consider when choosing a gas string trimmer.

And if the two are the only factors that you consider the curved shaft will be ideal for those with a small yard and shopping on a tight budget. The straight shaft trimmers, on the other hand, are the best choice for large yards and lawns.

Another way to pick between the two trimmers is by considering your needs. If you just want something for light yard clearing and trimming pathways, you will not need all the power and capabilities of a straight shaft trimmer because a curved shaft trimmer is more than enough.

However, if your trimming needs involve clearing under low hanging trees and bushes, decking and many other hard to reach places then you should be ready to spend more on a straight shaft trimmer.

The overall performance, durability, and extended reach make the straight shaft trimmer ideal for most trimming application. And so if cost is not a concern it is always a much better option than the curved shaft trimmer.
