Don’t want any surprises with your trimmer? Then look no further.
A Husqvarna 324L trimmer does everything you could ever expect one to do.
First, it is a powerful machine. It comes with a high-end gas engine, Honda-powered, and ready to handle the densest of grasses. It is a 25cc engine, perfectly designed to achieve 7,000 RPM and 0.9 HP per operation. That should be enough to cut through any amount of vegetation at any moment.
Second, it is super-handy. You get a Smart trimmer technology that helps you turn on the machine by pulling the cord a lot less than you would any other trimmer. This pairs up with the practical translucent fuel tank, an air-removal purge primer bulb, and a Tap ‘N Go line-releasing function.
And third, it is incredibly versatile. The straight shaft and the engine weigh as little as 5 pounds only. Given you’re an adult, using it won’t be any problem.

The whole design is surprisingly comfortable as well. A rubberized handle, a straight shaft, and a magnificent weight of only 18 pounds set it apart from the competition.
It works with 0.095-inch lines and can hold 20 feet per head. This should be enough to last several cutting operations before you need to reload.

How to Choose the Right 4-Stroke Trimmer?
Did you check our trimmers? What did you find? Oh, you’re a bit confused? Don’t worry, we have the solution.
Learning about trimmers in-depth may give you a better idea of what to go for. This section explains exactly what to consider and how you can fit a trimmer to your demands. Check it out:
- Types of Trimmers
There are two main types of trimmers: shaft and walk-behind.
As the name says, shaft trimmers use a pole as the body. This pole is typically 59 inches long. The focus is to make it easy for an average-height person to get the cutting head close to the grass.
What sets a shaft trimmer apart is the ability to reach difficult areas where other trimmers can, like narrow spaces between plants or the top of bushes.
A walk-behind trimmer, on the other hand, works more like a mower. It boasts two wheels that help it glide across a yard. The trimmer head is slightly larger than a shaft model and often provides a lot more power. Using it takes little effort but limits versatility exponentially.
- Engine Power
There’s probably nothing more critical after the type of trimmer than the power it offers.
Because we’re talking about 4-cycle trimmers powered by gas, you can expect a lot of power. But it’s not always the case.
As a general rule, go for trimmers with no less than 20cc of engine displacement (enough to cut light grass). For the best results, get a trimmer with 50cc (best price/performance ratio). High-power models can offer up to 150cc or more (ideal for high-density grass cutting).
- Trimmer Head & Cutting Swathe
The trimmer head is a vital part of the trimmer. It refers to the part where the cutting line is located.
Here, it’s wise to go for the broadest trimmer possible. A trimmer with 17 inches of swathe should suffice for most jobs. But if you want a smooth experience, go for swaths of no less than 22 inches.
At the same time, go for cutting heads with protection and auto-feeding line systems. A grass cover prevents clippings from going your way. And auto-feeding lines keep you from wasting time when reloading.
- Cutting Line
What type of trimmer line does the trimmer use? It’s important to know this because all trimmers work with different thicknesses.
The general thickness is 0.155 inches. However, it depends on the number of lines as well. Some trimmers use single-line, others use double lines, and others use quad lines. This will give you an idea of how they prefer (the more lines the trimmer offers, the denser the vegetation it can cut).
- Ease of Use & Comfort
There’s no point in getting a trimmer that eventually feels like a chore to use. Instead, it should be as pleasant as possible, so trimming your lawn is something you look up to.
For that, try to pick the most comfortable model possible. This often means low weight for less exhaustion, a comfortable handle, well-located controls, sufficiently handy adjustments, and an easy-to-start system. With that figured out, the trimmer won’t be a problem to use.
- Maneuverability & Portability
Alongside a comfy trimmer, you also want something that helps you maneuver with ease while still being a piece of cake to bring around.
Here, you should focus on trimmers that don’t weigh more than 50 pounds. At the same time, it should be as handy as possible, so you don’t have to carry it that much. That’s why walk-behind trimmers are often more portable.
Lastly, consider whether it can be stored with ease or occupy little space. The more practical the trimmer is when storing it, the better the experience you’ll have overall.
Straight Shaft Trimmer vs Curved Shaft Trimmer
When picking the deal trimmer, you’ll encounter a bit of a problem. Which one should you choose between a curved and shaft trimmer?
Here, we want to present a few factors to consider:
- A straight shaft is upright. There’s no bend across the pole. This makes them longer and more accurate.
- Curved shafts are bent. They have a bit of a curve which often reduces their length, making them lighter.
- Because straight shafts are longer, you can use them in situations where other short tools won’t work (e.g., tall bushes or under trees).
- Curved shafts being smaller are also a lot lighter, making it easy to maneuver, carry for hours, and even store.
- Comfort is more of a personal thing. But tall people often prefer straight shafts as they’re longer and allow them to trim grass without kneeling.
- Shorter people prefer curved shaft for the opposite reason: it allows them to reach grass without having to over-control the piece, trying not to hit the ground.
As you can see, it is more of a matter of preference and personal needs than everything. Make sure it’s something you will indeed get the most from, so you won’t be disappointed.
Frequently Asked Questions (FAQs)
Still have a doubt or two we didn’t answer before? Get comfy then. We’re going to answer the most common question below:
Is a 4-cycle trimmer better than a 2-cycle?
When it comes to performance, no. 2-cycle trimmers offer a bit more power given their motors are slightly larger. But when it comes to efficiency, environmental impact, and ease of use, a 4-stroke trimmer is way better. The power difference is not that much either, as 4-cycle trimmers have more torque.
What oil for 4 stroke weed eater?
Most weed eaters will tell you which type of oil works better. But in case it doesn’t, you can always default to 10W-30 or 10W-40 oil. Either way, the trimmer should function correctly, with little to no difference between these two.
Should you get a 4 stroke trimmer with attachments?
How long does a four-stroke weed trimmer last?
It depends on the quality of the piece and how you use it. 4-stroke trimmers that are used every day tend to last a couple of years. Those that are occasionally used (every month or two) can last over 5 years up to a decade.
