The DeWalt DCPS660AG2 POWERSHIFT Rammer: Cordless Compaction for Trenches and Foundations

Gas-powered rammers have been the standard for trench compaction and foundation prep for a long time. They work, but they come with a list of trade-offs: exhaust fumes in enclosed trenches, regular carburetor maintenance, fuel management on the job site, and noise that limits where and when you can run them. 

The DeWalt DCPS660AG2 POWERSHIFT 60Kg Class Rammer Kit puts a sealed brushless motor into a 60Kg class rammer and backs it up with 554Wh POWERSHIFT batteries. On a single charge, it'll compact up to 750 linear feet of trench at speeds up to 49 feet per minute. Here's everything you need to know.

The kit ships with the rammer unit plus two batteries and a charger — everything you need to put it to work immediately. The 554Wh batteries are DeWalt's POWERSHIFT platform, which is specific to their outdoor power and heavy equipment lineup. These aren't M18 or FLEXVOLT batteries — they're larger, higher-capacity POWERSHIFT units designed for heavy-duty cordless equipment like this rammer.

The DCPS660AG2 uses a sealed brushless motor — no brushes to replace, no carbon dust buildup, and no maintenance on the motor itself. More importantly, the sealed design keeps construction debris, water, and dust from getting into the motor during trench work. That's a meaningful advantage in site prep conditions where you're often working in muddy, confined trenches where contamination is a constant issue with open-vent motors.

Brushless motors also run more efficiently than brushed motors, which is part of why DeWalt can claim 750 linear feet per charge. You're not losing energy to friction the way a brushed motor does.

The speed selector lets you switch between high and low compaction speeds without stopping the tool. That's a practical feature on the job — different soil types and compaction layers need different approaches. Cohesive clay soils in the bottom of a trench often need slower, more deliberate compaction. You can adjust on the fly instead of stopping the rammer to change a setting.

The high speed setting pushes travel speed up to 49 feet per minute, which is competitive with gas rammers in the same weight class. In high-output trench work, that speed matters for productivity.

The soft start controls how the rammer spools up when you trigger it. Instead of going from zero to full compaction force immediately, the soft start ramps up in a controlled way. That's better for operator control at startup, reduces the jarring effect when the rammer fires up, and helps prevent the tool from bouncing away from you in the first moments of use. On narrow or challenging surfaces, that startup control makes a real difference.

DeWalt's TOOL CONNECT+ gives you data access through the DeWalt Site Manager app. You can track asset location, monitor tool utilization, and manage tool inventory across a job site or fleet. For contractors running multiple crews or managing equipment across several sites, that visibility is useful. It won't change how the rammer compacts soil, but it's a real operational advantage for asset management.

A 60Kg class rammer weighs around 132 lbs. Moving it around a job site matters. The DCPS660AG2 includes a transportation roller built into the base so you can roll it across a job site without lifting it. There's also a dedicated lift point for rigging it into and out of trenches, and an integrated transport handle for short-distance carrying. These aren't flashy features, but they make daily use significantly easier — especially when you're working alone or with a small crew.

The foot on a rammer takes a beating. It's the part that actually hits the soil thousands of times per hour. The DCPS660AG2 has a replaceable foot, which means when it wears out — and it will — you replace the foot rather than the whole tool. That's a maintenance and cost consideration worth noting, especially in high-production environments where rammers run all day.

There's also a bellows with a lubrication inspection window so you can check lubrication levels without fully disassembling the tool. Small detail, but it simplifies maintenance in the field.

The two included DCBPS0554 554Wh POWERSHIFT batteries are high-capacity units built specifically for DeWalt's heavy-duty cordless equipment. Each battery holds 554 watt-hours of energy — for comparison, that's significantly larger than a standard FLEXVOLT pack. This is purpose-built for equipment that draws serious current under load.

DeWalt rates the rammer at 750 linear feet of trench compaction per charge. That's a real-world output number based on actual compaction work, not a lab figure. Actual performance will vary depending on soil conditions, compaction speed, and terrain — cohesive soils and deeper fills will use more energy per foot than loose, sandy material.

The included DCBPSC0550 is a 550W fast charger. With two batteries in the kit, you can run one while the other charges, which helps reduce downtime on longer production days.

Rammers and plate compactors are both compaction tools, but they're not interchangeable. They work differently and excel in different conditions. If you're evaluating which type of tool you need, here's the breakdown:

Rammers — also called jumping jacks — are the right tool for trench work, backfill around foundations, and cohesive soil compaction. The narrow foot and high-impact vertical blows drive compaction force into clay and silt soils in ways that a plate compactor can't match. 

If you're backfilling a water main trench or compacting around a retaining wall footing, you need a rammer. If you're prepping a large parking lot subbase of crushed stone or gravel, a plate compactor is the better tool. Know your application before you decide.

The DeWalt DCPS660AG2 POWERSHIFT 60Kg Rammer Kit is built for contractors doing trench compaction and site prep work where battery power gives you an operational advantage. That includes utility contractors backfilling water, sewer, and conduit trenches; plumbers and HVAC contractors compacting around underground pipe runs; and foundation contractors doing perimeter compaction around footings and retaining walls.

The no-exhaust battery operation is a specific advantage in confined trenches and indoor foundation work. Running a gas rammer in an enclosed space has real safety implications — carbon monoxide accumulates fast in trenches and below-grade construction. A battery-powered rammer eliminates that issue entirely.

It's also worth noting that the TOOL CONNECT+ technology and Site Manager integration make this tool a good fit for larger operations tracking equipment across multiple sites. For a small contractor doing occasional trench work, a gas rammer may still make more economic sense. But for crews running rammers daily, the reduced maintenance overhead and operational flexibility of battery power are real advantages.

The DeWalt DCPS660AG2 POWERSHIFT 60Kg Class Rammer Kit is a purpose-built compaction tool for contractors who need real production capacity from a battery-powered machine. 

It compacts 750 linear feet per charge, reaches speeds up to 49 feet per minute, and does it without exhaust — which matters in confined trench environments. If your work involves regular trench compaction or foundation prep, this rammer is worth a serious look.
