Introduction

String trimmers are either manufactured with a straight shaft or curved shaft. This is not a factor that many consider while shopping. Most people are more concerned about the engine or motor’s power, the trimmer’s weight, price, and how comfortable it feels in hand.

Considering the design of the shaft, there’s what will make your work easier. Having a straight or curved shaft trimmer could streamline your tasks and help you work smarter. This post will take a look at the difference between straight shaft vs curved shaft string trimmers.

Straight Trimmer Description

Straight shaft trimmers are more popular than curved shaft trimmers because they are often longer. The rod extends straight from the head to the power source without bending. This design also allows manufacturers to play around with different types of drive mechanisms. The mechanism can either be a plastic or steel cable. In commercial-grade trimmers, it can be a solid steel driveshaft.

A solid steel driveshaft is more durable than that made from plastic. It can accommodate optional cutting blade attachments and heavy-duty replacement strings. In fact, most metal string trimmer blades work better with straight trimmers.

The trimmers use gearboxes to turn the rotational force generated by the engine or motor into speed. This helps to turn the head and produce more power which then translates to more strength for cutting. Also, having a more elongate shaft makes it easy to trim spaces that would be difficult to reach such as beneath a raised patio or deck.

Not only that, straight trimmers tend to be more comfortable for taller people. They eliminate the need to bend to reach the ground. This means that they can be used for long hours to tackle demanding tasks.

Strong Sides

1. Have better reach
2. More powerful
3. Tend to be more durable

Weak Sides

1. Can be heavier
2. Their elongated shaft can make them feel unbalanced

Curved Trimmer Description

Curved trimmers tend to form the letter J and have a hook-shaped bend just where the shaft meets the powerhead. Some have an elongated pole that forms the letter S. In all cases, curved trimmers tend to be shorter than straight trimmers.

A typical curved trimmer will have a drive cable inside the shaft that connects the trimmer head to the power source. The cable is made flexible so that it can easily pass through the curve. This tends to affect its durability since it has to spin and constantly bend inside the metal shaft. But, some cables come braided to reinforce them and improve their durability.

A curved shaft always translates to a shorter trimmer. This can be beneficial for longer tasks because the trimmer weighs less. It gives the user a better sense of control and less work in carrying the trimmer. Also, since the shaft isn’t as long, it also feels more balanced and comfortable, especially for shorter people. You can use it to work on smaller areas and yards that do not require heavy-duty trimming.

Since the powerhead is designed to point downward when holding it straight, the user is able to maneuver around flowerbeds and trees more easily. The curved trimmer can also be used closer to the ground to provide more leverage and a sense of balance.

Unfortunately, the shaft curve tends to get in the way of someone trying to access small spaces like beneath lawn furniture. The arched driveline also generates less power and torque when compared to straight trimmers. It also limits the type of driveline manufacturers to just cable drivelines. Curved shafts also don’t accommodate attachments and consumers tend to be forced to stick to lighter duty strings made from nylon.

Strong Sides

1. Provide more control
2. Weigh less hence are more comfortable to carry
3. Less expensive

Weak Sides

1. Tend to be less durable
2. Less powerful
3. May require taller users to bend when using them

Overview and Conclusion

Straight and curved trimmers have their own advantages and disadvantages. When deciding on which one to choose, consider the amount of work that lies ahead of you, the frequency with which you’ll use the trimmer, and your height.

Straight shaft trimmers are more durable and versatile. They are built with higher output in consideration, making them a great tool for heavy tasks. Their functionality makes sense to many people, especially professionals who spend most of their time with them. Their extended reach also helps to eliminate backaches and to reduce the time you’ll spend trimming.

Curved shaft trimmers are a great alternative for anyone who doesn’t have much ground to cover and doesn’t need to use the trimmer every day. They make it easy to work in tight spaces that are full of fixtures. Their weight not only gives the user more control but also ensures they are comfortable while at work. Those who are short also get to have an easier time since the trimmer isn’t long.

FAQ

Can you edge with a curved shaft trimmer?

You can use a curved shaft trimmer to edge your lawn if you know how to go about it. It can help you achieve the same results you would if you used an edger.

Which is better 2 cycle or 4 cycle trimmer?

A 2-cycle engine is always smaller in both size and displacement when compared to a 4-cycle engine. The latter is often double the size and removal of the former. As a rule of thumb, having a smaller engine with fewer parts means you’ll not need to do as much in maintenance. It also reduces the chances of the engine failing.

Which is better: straight or curved shaft trimmer?

Choosing between a straight and curved shaft trimmer often depends on different factors. Straight shaft trimmers are heavier, more powerful, and ideal for heavy tasks that require extended amounts of time. Curved shaft trimmers are lighter, shorter, and less powerful. They are great for more delicate work and feel comfortable in the hands of shorter users.
