What the CPSC Data Shows
Rotary Power Lawn Mowers (CPSC product code 1448, in the Lawn & Garden Equipment category) generate an estimated 4,887 emergency-room visits every year in the United States, adding up to roughly 97,740 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 38/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are declining by about 60% over the last five years, with the busiest year on record being 2010 (8,687 estimated ER visits) and the quietest 2022 (1,727 estimated visits).
The single most common ER diagnosis for rotary power lawn mowers is laceration to the finger, accounting for approximately 6,334 visits across the 20-year NEISS window, followed by strain, sprain to the lower trunk (6,063 cases). The 45-54 age group absorbs the largest share of injuries, about 19,326 cases over the NEISS window, and males appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 12.4% of ER visits involving this product end in hospital admission or transfer, and a small fraction (0.27%) result in fatality.
Beyond the hospital-sampled NEISS projections, this page also aggregates 263 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how rotary power lawn mowers fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

carpal tunnel developed from no vibration protection on gas powered lawn mower handle
On 6/11/22 I purchased a 21" ATLAS 80 volt lawnmover from Harbor Freight in Muskegon, Michigan. I was very impressed with the mower and posted related comments. However, in the FALL I folded up the mower handle for storage. This Spring, I placed the handle back in place and installed the charged batteries. The mower lurched forward at full throttle and ran up my shin bone, scraping it badly. Thank goodness, the mower blades are activated by a separate process and did not do more damage. I finally determined that the folding up for storage process pulled the BAIL CONTROL BAR up and into a locked on position. When the handle was put back in place the bar remained locked on. Contacted Harbor Freight on 6/12, 6/14 and 7/13/2023 without response on steps taken to correct defect.
Kobalt 40v cordless mower started smoking. At first thought it was the battery, but after letting it sit for a couple of hours and replacing battery, the mower is still smoking when in use. Checked online for any fixes and came across information on a recall for the mower.
Fuel cap does not seal adequately on Kohler Courage XT engine on a Toro lawn mower. Tends to leak. This has been an issue for several years from date of purchase.
(09/02/2016) The consumer stated that after mowing the lawn for about an hour, the blade came out from under the housing and landed at the his feet. The consumer noticed that the blade adapter and mounting screw was broken. The consumer stated that it appeared that the screw had loosened itself. No injury. (09/06/2016) The consumer contacted the firm to advised them of what happened. His call was disconnected while being transferred. The consumer will try to contact the firm again.
Part way into the 2nd year of use, I noticed frequent leaking of gasoline out of the top of the gas tank fill tube. A couple of months later, I noticed it was increasingly difficult to put the gas tank filler cap on securely. I finally realized the reason for this: the fill tube was no longer circular, it had become elliptical in cross section. The only way to fix this is to replace the gas tank, if that's possible, or the engine if the gas tank cannot be replaced separately. This Toro lawnmower has a Kohler engine.
I purchased a Greenworks corded lawn mower (Model number 25112). I was using it a couple weeks ago and it started smoking from the engine compartment. There was no way to open the engine area so I sawed off the top and the engine area was full of dried grass and other debris. I called the company and they were not concerned about it.
Fuel leaks from the filler cap on the engine. The filler neck on the tank is oval shaped. I replaced the gas cap which helped for a short time but it is leaking fuel again. I contacted the manufacturer of the lawn mower, Lawn Boy, who told me to stop using the mower and to contact Kohler, the engine manufacturer. I have tried to contact Kohler but received no response. The oval shaped filler neck is a defect in manufacturing. The gas cap will not seal properly. This not only is a fire hazard, but is also an environmental problem. Kohler needs to come up with a proper solution as simply replacing the cap has not worked.
