DeWalt Blower and Trimmer Combo: 20V vs 60V Kits and How Far One Battery Goes

A DeWalt blower and trimmer combo is worth buying if you want two shared-battery yard tools for a small-to-medium lawn and you already own, or plan to build on, DeWalt’s 20V MAX or 60V MAX FLEXVOLT batteries. The 20V MAX kits cover typical suburban edging and cleanup; the 60V FLEXVOLT kits are for larger properties, thick weeds and wet leaves. If your shop already runs Makita 18V LXT, Makita’s equivalent combo makes more sense than switching platforms.

What Comes in a Typical DeWalt Combo Kit

DeWalt bundles a brushless string trimmer and a handheld blower with one battery and a charger. The battery is usually the most valuable item in the box, which is why combos tend to cost less than buying the two tools and a pack separately. Configurations shift between seasons and retailers, so focus on the specs below rather than a single model number.

Figures are ranges across recent kit configurations. Airflow (CFM) moves volume of leaves; air speed (MPH) dislodges stuck debris. For general yard cleanup, CFM is the more useful number.

How Far One Battery Goes

A single shared pack is the combo’s biggest compromise: you trim, then blow, from the same battery. Here is a realistic budget for a 5.0Ah 20V MAX pack (about 90 Wh):

For a quarter-acre lot with ordinary edging, one 5.0Ah pack usually covers trimming plus a quick blow-off. Larger lots, or fall leaf cleanup, call for a second battery or a step up to FLEXVOLT.

Decision Matrix: 20V vs 60V vs Makita

The Trimmer Side: What to Check

Head type and line changes

Most kits ship with a bump-feed head. Reloading line is the most common annoyance with any cordless trimmer; look for a head that loads straight through the eyelets without disassembly. Keep the line size to what the head specifies, since oversized line overloads the motor and cuts runtime.

Speed settings

A two-speed trigger or switch matters more than peak power. Running low speed for routine edging can add a third or more to battery life.

Attachment capability

DeWalt’s 60V FLEXVOLT attachment-capable trimmers accept compatible edger, pole saw and hedge trimmer heads. If you want those later, choose an attachment-capable powerhead from the start.

The Blower Side: What to Check

• Variable-speed trigger with a cruise lock, so you can blow at low power around flowerbeds and full power on the driveway.
• Balance with battery installed. A nose-heavy blower tires your wrist in minutes; a rear-mounted battery usually balances better.
• Noise. Battery handheld blowers are quieter than gas, but full-speed boost is still loud; use hearing protection for sessions over a few minutes.

Ownership Realities

• Consumable cost: trimmer line is the main ongoing cost, typically a few dollars per refill. Pre-cut line or pre-wound spools save time.
• What wears first: bump knobs, line eyelets and the trimmer guard’s line-cutting blade. All are inexpensive replacement parts.
• Cleaning: brush grass from the trimmer head and motor vents after each use. Do not spray water into either tool.
• Battery storage: keep packs indoors in winter at partial charge. Garages that drop below freezing shorten battery life.
• Common mistake: blowing at full power first and trimming second. Trim first, then blow; you will finish the job on one pack more often.

Is the Combo Better Than Buying Separately?

If you need a battery and charger, yes: kit pricing almost always beats the sum of tool-only prices plus a pack. If you already own several DeWalt batteries, compare against buying both tools bare; occasional sales on bare tools can make that route cheaper and avoid collecting another charger.

Bottom Line

The DeWalt 20V MAX blower and trimmer combo covers routine edging and cleanup on typical suburban lots, especially if you already use DeWalt tools. Move to 60V FLEXVOLT for heavy weeds, bigger lots and leaf season. Makita users should stay with the LXT combo and consider 18V X2 tools when they need more power.
