Is the BILT HARD 22-inch trimmer good for thick weeds?

Yes. The 170cc four-cycle engine and 0.157-inch line are aimed at thick grass, weeds and light brush, and owners report it handles blackberries and tall grass. It is not a brush cutter for saplings.

Does it come with oil and string?

Yes. Two strands of trimmer line are already installed, and the box includes enough oil to fill the reservoir. Check the oil level before the first start.

How fast does the self-propelled drive go?

About 1.9 mph (3.06 km/h), and there is only one speed. Some owners find that pace a little fast for tight trimming.

What cutting heights does it offer?

Eight positions from 1.6 to 3.7 inches, adjusted at the deck. That range covers low trimming along edges and taller rough-cut work.

How much assembly is needed?

Very little. Owners report it arrives mostly assembled, with only the handle to adjust before use.

Is it hard to replace the trimmer string?

Some owners find it difficult, so expect a learning curve the first time. The 0.157-inch line size is the one to buy for refills.

What reviewers say

4.6 / 536 ratings

Owners rate it highly, praising the build, easy starting and the power to chew through blackberries and tall grass. The self-propelled drive is the feature most call a game changer. Complaints center on traction, a single fast walking speed, awkward string changes and one early primer bulb failure.
