Hart release an electric cordless carbon fiber trimmer

Your lawn mower can leave the best-looking cut in the neighborhood but it doesn’t mean much if you don’t trim and edge. The problem is high-performance string trimmers can strain your back and lightweight ones tend to lack the muscle to do the job quickly. Let’s see if the Hart 40V brushless carbon fiber string trimmer can bring balance to the force.

This model is strong enough to spin line up to 0.095-inch and was able to cut through neglected areas easily. It’s not strong enough to handle the thick stuff out, but any of your typical lawn grasses and weeds are no match.

The vibration levels are lower compare to gas trimmers. However, some of the premium residential and professional models reign it in more.

When it comes to runtime, it is possible to trim for just over 28 minutes on the 4.0Ah battery that comes in the kit. That’s running at high speed with 0.095-inch line in the longer cutting position. That’s enough to cover most lawns up to a 1/2-acre. The nice thing is Hart includes is a fast charger that gets you back in the game 3 times faster than the standard 40V charger.

Attachment capable

This trimmer is attachment capable and Hart uses a universal attachment connection. It works with all Hart PowerFit attachments and any other universal attachments you might have.

As an added bonus, the 3-position detent makes it easy to turn the string trimmer 90° and edge without messing with the handle ergonomics.

3-in-1 bump feed head

Hart includes a 3-in-1 trimmer head with this model. The standard head has a reversible cutter that you can set to 13 inches for tighter areas and longer runtime or 15 inches for larger areas and faster cutting.

There’s a second attachment for the head you can swap out that gives you a pair of plastic grass-cutting blades. These have more mass and can get through some of the stalkier grasses better than trimmer line. They’re more likely to damage paint and other soft materials, so be aware of what’s around you when you use them.

Weight and balance

The big deal about switching the shaft to carbon fiber is weight savings.

The bare weight of the trimmer is 8.8 pounds and a 4.0Ah battery brings the total package up to 11.1 pounds. It is a very reasonable weight for the performance level of this trimmer.

With that battery and the brushless motor in the powerhead, the balance is definitely toward the back. That’s normal for attachment-capable string trimmers.
