Trimmer vs Weed Eater Specs

Cutting width

Edge: BLACK+DECKER 20V MAX 12-Inch String Trimmer and Edger

The BLACK+DECKER 20V MAX 12-Inch String Trimmer and Edger offers a 12-inch cutting swath. This wider path covers more ground per pass. The BLACK+DECKER 10-Inch 20V Trimmer and Sweeper Combo provides a 10-inch cutting width. A wider swath reduces the time needed to clear larger areas of weeds. You may prefer the broader coverage for efficiency. The narrower option allows for tighter maneuvering in confined spaces. Choose based on how much area you need to cover in a single session.

Line feed system

Edge: Tie

The 12-inch model uses an EASYFEED push-button line advancement system. You advance the line by pressing a button, avoiding the need to bump the head on the ground. The 10-inch model features an Automatic Line Feed (AFS) system. This mechanism supplies line as needed during operation without manual intervention. Both systems keep the line at an optimal length. The push-button method gives you direct control over line extension. The automatic system offers continuous operation without stopping to bump the head. Your preference depends on whether you want manual control or hands-free convenience.

Weight and handling

Edge: BLACK+DECKER 20V MAX 12-Inch String Trimmer and Edger

The 12-inch trimmer and edger weighs 6.3 pounds. This weight includes the battery and charger in the kit. The 10-inch combo kit has a total weight of 10.5 pounds. However, the trimmer unit alone weighs only 4.5 pounds. The sweeper attachment adds 3.7 pounds. The lighter trimmer unit is easier to maneuver for extended periods. The heavier kit includes more tools, which increases the total mass. If you prioritize a lightweight single tool, the 12-inch model is better. If you need multiple functions, the combo kit is heavier but more versatile.

Power and speed

Edge: BLACK+DECKER 20V MAX 12-Inch String Trimmer and Edger

The 12-inch model features a 2-speed control. You can boost power for tough weeds or extend runtime for lighter tasks. It also includes a PowerDrive Transmission that increases torque at the string. The 10-inch model does not list speed controls or torque features in its specifications. It focuses on quiet operation and ease of use. The 2-speed option allows you to adapt the tool to different conditions. This flexibility can improve performance in varied yard conditions. The fixed speed of the 10-inch model offers simplicity without adjustment options.

Included batteries

Edge: BLACK+DECKER 10-Inch 20V Trimmer and Sweeper Combo

The 12-inch model comes with one 20V MAX Extended runtime Lithium Battery. The specific amp-hour rating is not listed in the key specs. The 10-inch model includes two 20V MAX Lithium Ion 1.5Ah batteries. Having two batteries allows you to swap them out for extended coverage. You can charge one while using the other. The 12-inch model requires you to wait for the single battery to charge. If you have a large yard, the extra battery in the 10-inch kit is a significant advantage. For smaller yards, one battery may be sufficient.

Versatility and functions

Edge: BLACK+DECKER 10-Inch 20V Trimmer and Sweeper Combo

The 10-inch model is a combo kit that includes a string trimmer, an edger, and a sweeper. It allows you to trim, edge, and sweep debris. The 12-inch model is a trimmer and edger combo. It does not include a sweeper attachment. The 10-inch kit offers three functions in one package. This is useful if you need to clear leaves and debris as well as trim.
