Greenworks 48V (24V x 2) 21" Brushless Self-Propelled Mower+12" String Trimmer+320CFM Blower,(2) 5.0Ah Batteries and 4A Dual Port Charger Review

Overview

The Greenworks 48V (24V x 2) 21" Brushless Self-Propelled Mower combo is a complete lawn care system designed for homeowners with medium-sized yards who want to ditch gas and oil without sacrificing power. It bundles a self-propelled mower, string trimmer, and 320 CFM blower with two 5.0Ah batteries and a dual-port charger, making it a turnkey solution for anyone ready to go electric. This setup is best suited for properties up to 1/3 acre, where you need reliable runtime and the convenience of swapping batteries between tools.

Who Should Buy This

• Homeowners with 1/4 to 1/3 acre lawns – The twin 5.0Ah batteries give you enough juice to mow, trim, and blow without running out mid-job. If your yard is smaller, you’ll rarely touch the second battery.
• Ex-gas mower owners tired of maintenance – No more stale fuel, oil changes, or pull cords. This is for anyone who wants to grab and go without prepping a gas engine.
• Budget-conscious buyers seeking a full set – At $449, you get three tools and two batteries. Compare that to buying a mower alone for $350 plus separate trimmer and blower—this combo saves real money.
• Eco-minded users who value quiet operation – This system is noticeably quieter than gas, so you can mow early Saturday without waking the neighbors or wearing earplugs.

Key Features Breakdown

• 48V (24V x 2) Battery System – Two 24V 5.0Ah batteries work in series to deliver 48V power. This means more torque for thick grass and longer runtime than a single 40V setup. Expect about 45-60 minutes of mowing on one charge, depending on grass conditions.
• 21-Inch Steel Deck – A solid, rust-resistant deck that’s wide enough to cover ground quickly but still nimble for gates and tight corners. Not the widest on the market, but ideal for typical suburban lots.
• Brushless Motor – More efficient and longer-lasting than brushed motors. It also runs cooler and quieter, and Greenbacks’ brushless motors generally hold up well over years of use.
• Self-Propelled with Variable Speed – The rear-wheel drive system lets you set your pace from a slow walk to a brisk stroll. It’s not the most powerful self-propel on hills, but it works well on flat to moderate slopes.
• 7-Position Single-Lever Height Adjustment – Quick and tool-free, with cutting heights from 1.5 to 4 inches. One lever controls all four wheels, so you can adjust on the fly.
• Dual Port Charger – Charges both batteries simultaneously in about 2 hours. That’s a huge plus: you can top off both packs at once, or keep one charging while you work with the other.
• 12-Inch String Trimmer – Curved shaft, bump-feed head, and 0.080-inch line. It’s a solid trimmer for edges and fence lines, though not heavy-duty for thick brush.
• 320 CFM Blower – Lightweight and effective for clearing clippings off driveways and patios. At 320 CFM, it’s not a commercial-grade blower, but it’s plenty for cleanup after mowing.

Pros

1. Complete system saves money – For $449, you’re getting a mower, trimmer, blower, two batteries, and a dual charger. Buying separately would cost $150+ more.
2. Two 5.0Ah batteries offer real runtime – Unlike cheaper kits with 2.0Ah or 4.0Ah packs, these 5.0Ah batteries let you mow a typical yard on one charge, with the second as backup for trimming and blowing.
3. Quiet and low-maintenance – No gas smell, no oil, no spark plugs. You can mow anytime and store it in the garage without fumes.
4. Brushless motor is efficient and durable – Expect years of reliable service, and the motor won’t bog down as easily in damp or tall grass.
5. Single-lever height adjustment – Simple and fast. You can change cutting height in seconds without crouching to adjust each wheel.
6. Dual-port charger is a time-saver – Most competitors include a single charger. This one charges both batteries at once, so you’re never waiting long.

Cons

1. Self-propel feels weak on steep hills – If your yard has a serious slope (over 15 degrees), the rear-wheel drive may struggle. It’s fine for gentle grades but not for hillside properties.
2. Batteries are proprietary – You can’t use universal battery adapters. If you lose or break a battery, replacement packs are expensive (around $150 each).
3. Trimmer line is thin and prone to breakage – The 0.080-inch line is fine for light trimming but snaps easily against thicker weeds or rocks. You’ll want to upgrade to a heavier line if your yard has tough edges.
4. Mulching performance is decent, not great – In dry grass, it mulches fine. But in damp or thick grass, clumps can form. You may need to bag or double-cut for a clean look.

Bottom Line

The Greenworks 48V 21-inch combo is one of the best values in cordless lawn care for the average suburban homeowner. It delivers solid power, decent runtime, and a complete tool set at a price that undercuts most competitors. The self-propel isn’t built for steep hills, and the trimmer line could be thicker, but for flat to moderate yards under 1/3 acre, this system will handle everything from mowing to edging to cleanup. If you’re ready to retire your gas mower and want one purchase that covers all your needs, this is a smart, reliable choice.

Frequently Asked Questions

How long do the batteries last on a full charge? With both 5.0Ah batteries, you can expect about 45-60 minutes of continuous mowing on flat, dry grass. Using the self-propel and cutting thick or tall grass will reduce runtime. The trimmer and blower use less power, so you’ll get longer runtimes from those tools—typically 30-40 minutes of trimming or 20-30 minutes of blowing on high.

Can I use the batteries from this kit with other Greenworks tools? Yes, these are Greenworks 24V batteries (the GMAX series). They work with any Greenworks 24V or 48V tool that uses the same platform. Many Greenworks string trimmers, blowers, chainsaws, and hedge trimmers are compatible. Just check the tool’s voltage requirements—some older 40V tools won’t work.

Does the mower have a bag, and how big is it? Yes
