Power & Performance
Running on a 24V Max platform with a 4.0Ah battery, this mower delivers consistent rotary cutting performance suited to thin-to-medium grass in maintained yards. The push-button start means full power is available instantly without RPM warm-up delays typical of gas engines.
For light weekly mowing of standard turf, the performance is well-matched to the deck size , but users dealing with tall or thick grass should expect reduced efficiency and faster battery drain.
Cutting System
The 13-inch composite deck uses a rotary blade system with 5 cutting height positions ranging from 1.0 to 2.55 inches, adjusted via a central height mechanism for convenience. The narrow deck width means more passes per yard compared to standard 18-21 inch mowers, but it also makes navigating tight spaces, narrow gates, and garden borders significantly easier.
Clippings discharge into a rear bag, keeping your lawn tidy without manual raking.
Drive & Handling
This is a push mower, meaning you supply all forward drive effort , there's no self-propelled assist. At 25.4 lbs, however, the lightweight build makes pushing feel natural even on slightly uneven ground.
The rear-wheel drive orientation provides stable tracking on flat terrain, and the compact 13-inch footprint improves maneuverability in tight areas where larger mowers struggle. Hilly terrain suitability is unconfirmed, so flat-to-gently-sloped yards are the recommended use case.
Battery / Fuel
The 24V 4.0Ah battery delivers approximately 22 minutes of runtime per charge , below average for cordless mowers but offset by the inclusion of two batteries, giving you roughly 44 minutes of total runtime before needing a full recharge. No gas, no oil changes, no spark plug replacements, and no fuel storage concerns , maintenance is limited to blade care and deck cleaning.
Charge time details should be confirmed in the product manual, but having two batteries means you can charge one while using the other.
Who Is This Mower For?
Ideal For
- ✓ Homeowners with small urban or suburban yards up to ~2,000 sq ft who can rotate both included batteries for full coverage
- ✓ Apartment dwellers or condo owners with patch lawns who need a lightweight, easy-storage mower , 25.4 lbs and a 13-inch deck store in minimal space
- ✓ Eco-conscious users wanting zero-emissions mowing power without sacrificing the convenience of push-button start
- ✓ entry-level-minded buyers who want both a mower and a grass trimmer in a single purchase without buying two separate tools
Not Ideal For
- ✕ Owners of medium to large yards (over ~2,500 sq ft) where the 22-minute runtime and narrow 13-inch deck width will make mowing a multi-session chore
- ✕ Users with thick, overgrown, or dense grass types that demand higher sustained mower power and torque than a 24V system delivers
- ✕ Anyone who needs mulching or side discharge options, as this mower only supports rear bag collection
Assembly is required out of the box, which for a mower of this size and weight typically involves attaching the handle, clipping in the grass bag, and inserting the battery , estimated at 15-20 minutes for most users.
Charge both batteries fully before first use so you have maximum runtime available for your initial mow
Attach the grass trimmer and familiarize yourself with the battery swap process before starting , the same 24V batteries power both tools

FAQ
How long does the battery last on the LawnMaster 20VMWGT mower?
Each 4.0Ah 24V battery provides approximately 22 minutes of runtime, which is below average for cordless mowers. However, the kit ships with two batteries, giving you up to ~44 minutes of combined mowing time before you need a full recharge , enough for most small yards in the 1,500-2,000 sq ft range.
Can I use the same batteries in both the mower and the grass trimmer?
Yes , both the 13-inch mower and the 10-inch grass trimmer in this combo run on the same 24V Max battery platform. This means you can swap either of the included 4.0Ah batteries between tools freely, making it a genuinely flexible small-yard system.
Is the LawnMaster 20VMWGT self-propelled?
No, this is a push mower , you provide all forward movement. The trade-off is that at just 25.4 lbs (less than half the average walk-behind mower weight), the physical effort required is minimal for flat yards.
It is not recommended for steep or hilly terrain.
What cutting height positions does the LawnMaster 13-inch mower offer?
The mower has 5 cutting height positions with a range from 1.0 to 2.55 inches, adjusted via a single central lever. This height range suits maintained turf but is on the lower end , if you frequently let grass grow tall between cuts, you may hit the maximum height limit more quickly than with a wider-range mower.
Does the LawnMaster 20VMWGT mulch or side-discharge clippings?
No , this mower only supports rear bag discharge. Clippings are collected into the included grass bag, which you'll need to empty during longer mowing sessions.
If mulching or side discharge is important for your lawn care routine, you'll want to consider a different model.
What yard size is the LawnMaster 20VMWGT best suited for?
The combo is best matched to small yards up to roughly 2,000 sq ft when using both included batteries back-to-back. The 13-inch cutting deck width means more passes than a standard-width mower, so larger yards will take noticeably longer to cover and may exceed total battery capacity before completion.
Bottom Line
The LawnMaster 20VMWGT is a smart buy for small-yard homeowners who want a complete mowing solution , mower and trimmer , in one cordless, lightweight, low-maintenance kit. The 22-minute single-battery runtime and 13-inch deck width are real limitations that make it unsuitable for medium or large properties, but for compact lawns where ease of use, quiet operation, and storage efficiency matter most, it delivers solid value.
Anyone with a yard larger than ~2,000 sq ft or dense, challenging grass should step up to a more powerful platform.
Best for small flat yards under 2,000 sq ft where a complete cordless mower-and-trimmer combo, lightweight design, and push-button convenience are the priority.
Consider alternatives if your yard exceeds 2,000 sq ft, features hilly terrain, or requires mulching capability , the limited runtime, narrow deck width, and bag-only discharge will frustrate in those conditions.
