Here are some of the reasons that we like the Husqvarna 324L.

Powerful engine really cuts it

The substantial 25cc 4-stroke engine on this thing has a 1.07HP output that will get through your toughest weeds without bogging down. It has an air purge to prime the engine for easiest starting. Husqvarna’s patented Smart Start feature is designed to allow the user to start the engine easily with the minimum of effort. Most of the time it will start with one or two pulls of the starter cord.

And of course, there is no mixing oil and gas, so just fill it up with unleaded gas and get started trimming!

Straight shaft lets your reach more weeds

The straight shaft design transfers power down the cable to the trimmer head efficiently and effectively. And you can get under the bushes and other obstacles more easily than with a curved shaft.

Adjustable handle for added user comfort

The padded loop handle adjusts along the shaft to fit your arm length and height. The adjustment is within a limited range that is marked on the shaft but this should work for most people. The comfortable grip minimizes discomfort from vibration for a less jarring trimming experience.

The shaft is also fitted with a vibration damping system to further reduce user discomfort.

Quick and easy line feed

Tap n' Go Bump Feed
Tap ‘n’ Go Bump Feed

Husqvarna 324L trimmer uses the Tap ‘n’ Go bump feed feature so all you do is tap the trimmer head against the ground while it is spinning and a fresh supply of line with spin out with the centrifugal force. Tap and keep on trimming!

The fairly standard 17-inch cutting swath allows you to make a substantial dent in the weeds for every swing of the trimmer.

So, that’s what’s great about the Husqvarna 324L, but are there any downsides? Well, that depends on how you look at it.

Not attachment capable

It’s a solid product with largely positive user feedback and a lot of happy customers. But it is a dedicated string trimmer, though, and it doesn’t allow for rigid brush cutter attachments, so don’t plan on using it for heavy brush and small sapling removal.

It also does not have a split shaft that would allow more sophisticated attachments like pole saws, blowers and edgers. If you are interested in a Husqvarna trimmer that could do this, please see our review of the Husqvarna 128LD 2-stroke model.

If you want to stick with a 4-stroke trimmer, we’ve reviewed several others that have attachment capabilities including the Poulan Pro PP428S and the Troy Bilt TB575EC.

If you want a high-torque trimmer for commercial or heavy residential use, you might like the Makita EM2652LHN.

Doesn’t come with a harness

This trimmer doesn’t come with a harness or strap to support it with your shoulders. It is not the heaviest of trimmers, at 13.1 lbs, but a strap would have been a nice feature. It is possible to add one, but it isn’t readily designed to accept one, so you may have to do some creative rigging.

Straight shaft best for taller users

This all depends on personal preference, of course, but shorter people, particularly petite women, may find using a straight shaft trimmer causes more strain on the body than a curved shaft trimmer. This is true across the board and doesn’t apply only to the Husqvarna 324L.

So should you invest in the Husqvarna 324L 4-cycle String Trimmer?

We really like the Husqvarna 324L and we think you will too. If you want a top quality dedicated string trimmer that is dependable, starts easily and provides commercial grade operating power, this might just be the best choice for you.

At an MSRP of $340, it is not the cheapest machine in its class, but you get the satisfaction of owning a high quality product that is going to last and give you dependable service.

If you are looking for a more all-in-one trimmer, you might want to opt for a Poulan Pro PP428S or the Troy-Bilt TB575EC. Just click on those names for our review of those trimmers.
