Greenworks prints its decibel figures on greenworkstools.com, in feature bullets, specification rows and sales copy. Its US owner's manuals, including those for each tool on this page, carry no acoustic figure.
The wording shifts from page to page. The 60V backpack blower has a plain "Noise 72.8 dB" row. The 40V snow shovel's row reads "Noise Level (User) 76.7 dB". The Pro 80V 21 inch mower has three rows at three distances, while the robot mowers, chainsaw and augers tuck their number into a sales line.
None of those formats names a weighting, a test method or the setting the tool ran at. Greenworks hedges in the FAQ under its blowers: "DB rating does depend on the model." Nothing on the site says the figures come from one shared method, so we compare them only within a tool type.
How quiet is the Greenworks AiMowbot robot mower?
The Greenworks AiMowbot robot mowers are rated 54 dB by their maker, the lowest figure on greenworkstools.com. All three US models, the C20, C30Z and C40, carry it, with no distance or test named.
Start with the C30Z. It covers 3/4 acre on two driven wheels with an 8 inch cut and wire-free RTK navigation, and at $1,599.99 it was the only AiMowbot Greenworks listed as available on October 23, 2026. The half acre C20, $999.99, and the C40, $1,499.99, both showed sold out.
The C40 page words its figure two ways: "quiet 54dB operation" in the feature list and "Operates under 54 dB(A)" further down. The second is a ceiling rather than a reading, so we treat 54 dB as the shared claim and do not read the C40 as quieter. The same page gives the C40's area as both 1 acre and 0.5 acre.
A robot's 54 dB cannot be set against the push mower figures below. It describes a small blade on a slow machine that runs unattended, heard from a distance Greenworks does not give. For other brands, see quiet robot mowers.
How loud is a Greenworks lawn mower?
Greenworks gives a US figure for one walk-behind mower, the Pro 80V 21 inch push model: "DB @ 0' (USER) 84.9dB". The other current Greenworks walk-behind and riding mower pages we opened list no number.
The same table carries two more rows, "DB @ 15' (NEARBY) 95.4dB" and "DB @ 50' (LONG RANGE) 61.83dB". Sound normally weakens as you walk away from its source, so a reading 10.5 dB higher at 15 feet than at the handle points to an entry error, a different test or a different setting. Greenworks does not say which.
We list the mower for its user figure and quote the other two as printed. It is a 1500W push mower with a steel 3-in-1 deck, blade speeds of 2800 and 3200 RPM and two 2.0Ah batteries, at $569.99 on sale from $599.99. Greenworks does not say which blade speed its rows describe.
One more mower has a figure, from Europe rather than the US site. The 24V 13 inch LM1322 matches the European GD24LM33 on its printed specifications, and that model declares an operator sound pressure of 79.6 dB(A). The European section below explains the match; the two mowers' figures come from different sources and are not ranked against each other.
For walk-behind mowers from other makers, see quiet battery lawn mowers.
Which Greenworks leaf blower is the quietest?
The quietest rated Greenworks leaf blower is the 48V (24V x 2) BL2002B00 backpack, which Greenworks says "Operates at only 65 dB". The 60V backpack, item 2418502, has a "Noise 72.8 dB" row. No Greenworks handheld blower lists a figure.
On paper the 48V model is also the stronger of the pair: 730 CFM and 185 mph against 550 CFM and 140 mph, from two 24V batteries. It weighs 11 lbs without batteries and sold for $449.99 with two 8.0Ah packs and a charger. The 60V backpack costs $299.99 with one 5.0Ah battery.
Both numbers arrive with nothing attached. Greenworks does not say whether 65 dB applies at the operator or across the yard, or whether the blower was on turbo, and the 72.8 dB row is just as bare. They show how Greenworks orders its own backpacks, and that is as far as they reach.
Greenworks' other backpacks speak in ratios. The 82V 690 CFM model says "This electric model is 1.5x quieter than gas-powered blowers", giving no figure for either side, and none of the 24V, 40V, 60V or 80V handheld blower pages we opened shows a decibel row. For blowers rated under a stated method, see quiet leaf blowers.
How loud is a Greenworks pressure washer?
Greenworks rates its 60V, 80V and corded/60V hybrid 3000 PSI pressure washers at 68 dB. The battery models call that "Very quiet at only 68 dB", without naming the quantity, sound pressure or sound power, or where it applies.
With one figure across all three, the choice comes down to power source and price. The 60V PW60L01 was $399.99 as a bare tool and the 80V PW80L00 $449.99. The hybrid, which runs from an outlet or from 60V batteries, cost $699.99 with two 5.0Ah batteries or $649.99 alone. Each lists 3000 PSI with a 2200 PSI ECO mode.
Greenworks' corded washers make no such claim. The 1800 PSI electric model offers only "Low Noise. Easy on the ear, low decibel cleaning". The battery models' operator manuals have no acoustic section either, so the 68 dB lives on the product pages alone. For washers from other makers, see quiet electric pressure washers.
How loud are Greenworks augers, chainsaws and snow shovels?
Four Greenworks tools outside mowing and blowing carry a figure: the 60V earth auger at 73 dB, the 80V auger powerhead at 80 dB, the 80V 18 inch chainsaw at 85 dB and the 40V snow shovel at 76.7 dB.
The 60V auger's page carries its figure twice, in a "Low Noise 73 dB" spec line and in the claim "Over 8x quieter than a gas auger". It turns at 210 RPM forward and 50 in reverse with 59 ft-lbs of torque, for $399.99 without a battery.
The 80V auger pages disagree with each other. The powerhead sold alone, $329.99, promises "ultra-quiet (80dB)" and 81 ft-lbs. The sold out 80V kit page quotes 73 dB and 59 ft-lbs, the 60V auger's numbers, and lists a "60V Earth Auger Powerhead" in the box. We give the powerhead its own 80 dB and set the kit's figure aside.
The Pro 80V 18 inch chainsaw "Runs at 85 dB", Greenworks says, set against a "gas chainsaw at 110 dB". Neither number comes with a distance. The saw showed sold out at $379.99 on October 23, 2026, and no other Greenworks chainsaw or pole saw page we opened has a figure.
The 40V 12 inch snow shovel's row, "Noise Level (User) 76.7 dB", is one of only two Greenworks figures tied to the operator. It also showed sold out, at $329.99, and its page contradicts itself on the motor: brushless in the feature text, "Brushless Motor No" in the table. None of the Greenworks snow thrower pages we opened lists a figure.
Greenworks string trimmers, hedge trimmers, edgers, handheld blowers, pole saws, cultivators, dethatchers and riding mowers have no decibel figure on any US page we opened, and neither do most of its push mowers, chainsaws and snow throwers.
The riding and zero turn mowers come closest, with the line "Low Noise. Easy on the ear, low decibel mowing" in place of a number, and many walk-behind mowers repeat it. The string trimmer and hedge trimmer pages do not mention decibels at all.
We also opened more than 60 US owner's manuals, from the BL2002B00 blower to the AiMowbot robots and the 48V chainsaws. None prints a measured sound level, which leaves the product pages as Greenworks' only US source. For trimmers that other makers rate, see quiet cordless string trimmers.
Do Greenworks' European noise declarations apply to US models?
No, with one exception. Greenworks' European manuals declare sound pressure and sound power for each tool, but only the European GD24LM33 mower matches a US model, the 24V 13 inch LM1322, on the specifications both manuals print.
Greenworks' European manual library lists 23 manuals, and each prints an internal code such as LMG401 beside the European model name. Those codes also appear on US manuals, which is how we found candidate twins. A shared code alone proved too loose, since the US manuals for a 610 CFM and a 700 CFM 60V blower both print BLC402.
For the LM1322, both manuals print LMG401, a 24 V motor, 3550 RPM at no load, a 13 inch or 330 mm cut and a 25 to 70 mm height range. The GD24LM33 declares "LPA= 79.6 dB(A), K= 3 dB(A)" at the operator, a measured sound power of 90.2 dB(A) and a guaranteed 96 dB(A), citing EN ISO 3744.
Several near-twins fell short on one printed number. The 60V 610 CFM blower shares BLC402 with the GD60AB, yet Europe prints 17.2 m³/min of air where the US manual prints 610 CFM. The 48V 14 inch chainsaw shares CSE405 with the GD24X2CS36, whose bar Europe gives as 350 mm. The 40V 12 inch trimmer and the G40LT differ on weight and cutting path.
The guaranteed 96 dB(A) is a ceiling Greenworks commits to under the EU's outdoor noise directive, not a typical reading. None of the European figures belongs in the same comparison as a bare US dB.
How do Greenworks' numbers compare with EGO's?
Greenworks' numbers cannot be ranked against EGO's, Ryobi's or any other brand's, because Greenworks names no test method for its US figures. A bare 65 dB and a declared sound pressure at the operator's ear are different measurements.
The one Greenworks figure with a declared method, the GD24LM33's 79.6 dB(A) at the operator, could in principle sit beside another maker's European operator figure for a similar mower. Even then it describes one small 13 inch mower, not the brand. EGO's figures are on the EGO outdoor tool decibels page.
