Concrete finishing is critical to getting the results your clients demand, and walk-behind trowels are a big help. Dealing with a gas engine or trailing a cord is so last decade. Thanks to the brilliant folks at Milwaukee, there’s an MX Fuel cordless version coming to a jobsite near you!
Battery power has already made a strong case for replacing gas on many jobsites, but concrete finishing is a tougher ask. When you’re working wet concrete, you don’t get a do-over. The tool has to start, run, balance well, and deliver enough power to pan and finish before the slab gets away from you.
That’s what makes Milwaukee’s MX FUEL Walk-Behind Trowel lineup so interesting. Instead of simply making a cordless version of a small finishing tool, Milwaukee is taking aim at the gas-powered walk-behind trowel with a 36-inch model designed for open-slab work and a 24-inch edging model for working near walls, forms, and other tight areas.
Milwaukee MX FUEL 36-Inch Walk-Behind Trowel
The Milwaukee MX FUEL 36-inch Walk-Behind Trowel is built around Milwaukee’s MX FUEL cordless equipment platform and delivers 5 horsepower performance from a brushless motor. Milwaukee pairs that with a maximum blade speed of 130 RPM, giving concrete finishers the ability to pan, finish, and burn in a slab without dealing with a gas engine.
The most obvious benefit is what you don’t have to deal with. There’s no pull-start, no fuel mixing, no gas storage, no oil changes, and no direct emissions. Push-button starting is a big deal when timing matters, and the ability to run indoors or in enclosed areas without engine exhaust opens up more flexibility for crews working in commercial or residential spaces.
Runtime is always the big question with battery-powered concrete equipment. With the kitted MX FUEL REDLITHIUM FORGE HD12.0 battery, Milwaukee rates the 36-inch trowel for up to 25 minutes of runtime per charge. According to Milwaukee, that works out to panning roughly 2,000 square feet or finishing around 500 square feet over five passes, depending on the application and conditions.

What Changes Compared to Gas?
The comparison to gas is where this tool gets interesting. Gas walk-behind trowels are familiar, proven, and available in a wide range of sizes. However, they also bring the usual small-engine hassles: pull-starting, maintenance, fuel, fumes, noise, and downtime when the engine doesn’t cooperate.
Milwaukee’s approach trades the gas engine for instant-start battery power. For crews already invested in MX FUEL equipment, the trowel fits into the same battery ecosystem as other larger Milwaukee concrete and light equipment tools. That doesn’t automatically make it the right choice for every concrete crew, but it does make a lot of sense for contractors who value lower maintenance, indoor capability, and simplified jobsite logistics.
The other practical advantage is control. Milwaukee includes an ergonomic throttle design, fine blade pitch adjustment, handlebar height adjustment, and a lift hook for moving the machine around the jobsite. Those aren’t flashy features, but they matter when you’re trying to maintain balance and control during a finish. Price is around $7,999 for the kit with three HD12.0 MX Fuel batteries.
Milwaukee MX FUEL 24-Inch Edging Trowel
Milwaukee also has a 24-inch Walk-Behind Edging Trowel for working closer to walls, columns, forms, and other obstacles. It still delivers 5HP performance, but the smaller size and flat-rimmed design help it get into areas where a standard 36-inch machine can’t reach as effectively.
The edging model has a higher maximum blade speed of 160 RPM and Milwaukee rates it for up to 35 minutes of runtime per charge. It’s not a replacement for the 36-inch trowel on larger open slabs, but it gives crews a battery-powered option for detail finishing and edge work without switching back to gas.
- Model: Milwaukee MXF324-2HD
- Trowel Size: 24 inches
- Performance: 5 HP
- Max Blade Speed: 160 RPM
- Runtime: Up to 35 minutes per charge
- Dimensions: 56 x 30 x 36.75 inches
- Bare Weight: 124 pounds
- Battery System: MX FUEL
- ONE-KEY Compatible
Battery and Charging Setup
The 36-inch kit includes three MX FUEL REDLITHIUM FORGE HD12.0 battery packs and an MX FUEL Super Charger. Milwaukee says the Super Charger can bring an HD12.0 pack to a full charge in 65 minutes. Both the battery and charger are COOL-CYCLE capable, using active cooling to help reduce downtime when rotating packs on demanding jobs.
That battery setup matters because this is not the kind of tool you want sitting around waiting on a charge. With three packs in the kit, Milwaukee is clearly aiming this at professional crews that need to keep working rather than treating battery power as a novelty. Price is around $6,499 for the kit with two HD12.0 MX Fuel batteries.
ONE-KEY Tracking and Security
Like many of Milwaukee’s higher-end tools and equipment, the MX FUEL trowels are ONE-KEY compatible. That gives contractors the ability to track, manage, and secure the equipment through Milwaukee’s app-based system. On a high-dollar tool that may move between trucks, crews, and jobsites, inventory control is more than a convenience feature.
Who Should Consider the Milwaukee MX FUEL Trowel?
The best fit is a concrete crew that wants to reduce small-engine maintenance, work more cleanly indoors, or standardize around Milwaukee’s MX FUEL equipment platform. It’s also a compelling option for contractors who already use battery-powered saws, vibrators, screeds, or other concrete tools and want to keep more of the job on one cordless system.
For crews finishing very large slabs all day, gas still has the advantage of quick refueling and a long history in the trade. But Milwaukee isn’t pitching this as a toy or a light-duty convenience tool. With 5HP performance, professional blade speeds, and a runtime/charging setup built around FORGE HD12.0 batteries, this is clearly designed to compete in real finishing applications.
Final Thoughts
Milwaukee’s MX FUEL Walk-Behind Trowels show how far battery-powered equipment has come. The 36-inch model gives crews a cordless option for open-slab finishing, while the 24-inch edging model handles the tighter work near obstacles. Both deliver the main benefits we want from battery equipment: instant starting, less maintenance, lower noise, and no direct emissions.
The big question is whether runtime and battery logistics line up with the way your crew finishes concrete. For many contractors, gas will continue to make sense. However, for crews that want a cleaner, lower-maintenance alternative—and especially those already buying into the MX FUEL platform—Milwaukee’s battery-powered trowels are a serious step forward for cordless concrete finishing.
