Best String Trimmers Under $75 (2026)

This cordless kit ships with two 4.0Ah batteries and a fast charger, which makes it the most complete package in the guide. Two packs of that capacity are worth far more than the two 2Ah packs that come with some rivals, because runtime scales with amp-hours and a 4Ah pack holds twice the energy at the same voltage. The 9500 RPM motor is a no-load figure, so treat it as a ceiling for light grass.

A 12-inch swath and a trimmer-to-edger conversion cover the usual small-yard jobs: lawn edges, fence lines and the strip along a driveway. Compared with the HEYWORK it has the faster motor claim and a lighter weight class, and compared with the corded units it trades unlimited runtime for freedom of movement.

Ownership is simple. Keep packs indoors, swap when one sags and replace the line before it wears short of the swath. The brand is unnamed in the listing, so keep your receipt and check the return window in the first month. Charge both packs after the season ends and store them half full, since a fully drained lithium pack left on a shelf loses capacity. Expect to buy replacement line before you need new batteries.

The BLACK+DECKER corded trimmer uses a 4 amp motor to spin a 13-inch swath with automatic line feed. The auto-feed spool advances line without bumping the head on the ground, which saves effort on long edges. A built-in auxiliary handle improves balance and reduces wrist strain.

A corded motor never runs flat, so it will finish a job that would drain a 2Ah cordless kit. The cost is the cord: you need an outdoor extension and must keep it behind you. Compared with the 14-inch 6.5 amp BLACK+DECKER in this guide it is lighter and weaker, and compared with the WEN it has a wider swath and a more established parts channel.

The brand has a long track record, so replacement spools and parts are easy to find. Store the cord coiled loosely and replace line when it drops below swath length. Wear long pants and eye protection, because even a small corded head throws stones and twigs. Coil the cord loosely rather than wrapping it tight around the shaft, which cracks insulation over time.

This is the strongest machine in the guide on paper: a 6.5 amp motor with a Powerdrive transmission that raises torque at the head. The swath is 14 inches, the widest here, and the head rotates to a wheeled edge guide for sidewalk and bed edging.

More amps help in thicker grass where the 3 and 4 amp units bog. Compared with the 4 amp BLACK+DECKER, it clears faster and handles heavier growth, at the cost of more weight. Compared with the cordless kits it does not run out of charge but it needs a cord.

Expect to use a 16-gauge or thicker outdoor cord and to replace line often, since the wider swath eats line faster. If your lawn is mostly flat, the wheel guide will keep the edge straight along a driveway. Keep the vents clear of grass clippings because the bigger motor produces more heat.

The WEN ET1003 is built to be short and light: 4 pounds and 37.5 inches long. A 3 amp motor spins to 10,500 RPM and the automatic feed keeps line length consistent. That compact length makes it comfortable for shorter users and easy to store.

It is the least powerful machine here, with the narrowest swath at 10 inches, so it needs more passes. Compared with the 6.5 amp BLACK+DECKER it is a quarter of the torque in theory but far easier to carry.

It makes sense as a tool for tidying around a patio, balcony planters or small beds. Do not expect it to cut waist-high weeds. Because it is short, it is easy to hang on a garage hook and out of the way. Do not expect it to handle woody stems, and keep it away from damp grass that bogs the head.

HEYWORK pairs a 20V platform with two 4Ah batteries, an 8000 RPM motor and automatic line feed. The 6.3-pound weight is on the heavy side for a cordless unit in this class because of the larger batteries. An adjustable grip helps reduce arm fatigue.

Compared with the 21V kit it has a slower motor claim, and compared with the 3.5-pound 20V unit in other guides it has more battery and more weight. The 4Ah packs are the real value.

It suits a yard of modest size where you want to work for 30 minutes at a time. With larger packs comes extra weight, so use the adjustable grip and switch hands occasionally. Check the head for wrapped grass after each tank of work.

This lightweight cordless model is marketed to small lawns and older users. It has a 9000 RPM motor, two 2Ah batteries with fast charging and a trimmer-to-edger switch.

With only 2Ah per pack, it holds half the energy of the 4Ah kits, so runtime is the compromise. Compared with the HEYWORK, it is lighter and cheaper but runs out sooner.

It is a sensible tidy-up tool for a tiny yard. Charge the batteries on a flat surface and do not leave them on the charger for weeks. This is a sensible machine for the person who trims for ten minutes a week.
