§ FAQ

What is the cutting swath on the DCST922B?

The DCST922B has a fixed 14-inch cutting swath, using 0.080-in. diameter line with the QuickLoad spool system for fast line replacement.

Does the DCST922B have auto-feed or bump-feed line advancement?

The DCST922B uses DEWALT's QuickLoad spool system, which allows fast and easy line replacement by loading pre-cut line directly into the head without disassembly. It does not use a traditional bump-feed mechanism.

What batteries are compatible with the DCST922B?

The DCST922B works with any DEWALT 20V MAX* battery, including compact 2.0Ah, standard 4.0–5.0Ah, and XR high-capacity packs. For best runtime, DEWALT recommends XR 5.0Ah or larger batteries.

How long does the battery last per charge on the DCST922B?

Runtime varies by battery capacity and speed setting. On the Lo speed setting with a 5.0Ah battery, users report covering approximately 1,000 sq ft or more. The Hi/Lo speed switch lets you trade power for runtime.

Does the DCST922B fold for storage?

Yes. The folding hinge mechanism reduces the tool's length by 40% when folded compared to fully extended, making it easier to store in a garage or truck bed.

Can the DCST922B handle thick weeds and overgrowth?

The brushless motor delivers sufficient torque for moderate grass and light weeds. For very thick brush or overgrowth, users report switching to Hi speed. For heavy commercial use, a 60V FLEXVOLT model like the DCST980 is a better fit.
