You know it’s springtime when you hear certain sounds in the fresh morning air: the gentle rumble of an approaching thunderstorm, the soft buzzing of bees pollinating flowers, the singing of songbirds announcing their return . . . and that overzealous neighbor who always starts mowing before 7 a.m. on Sundays!

You know what that neighbor needs? A robotic mower. Most operate within the range of 55 to 60 decibels (dB). That’s the average level of a conversation between two people speaking in a soft to normal voice. Your neighbor’s gas-powered mower, like others, probably ranges between 90 to 100 dB. That’s the same level of noise produced by hairdryers, blenders and motorcycles.

You could also tell your neighbor about the other great advantages robotic mowers have, including:

Time savings
Whether you’re on vacation or doing projects around the house, robotic mowers operate autonomously, allowing you to set a schedule and forget about mowing. When the mower’s battery is nearly depleted, the mower heads to its station for recharging, which usually takes one to three hours. Then it heads back to keep mowing where it left off.

Less maintenance
The blades on a robotic mower should be replaced every two to three months. Other than that, occasionally clean the undercarriage, then check and lubricate moving parts, and you should be set. Compare that to the hassle of removing and sharpening blades and changing oil when relying on a gas-powered mower.

Healthier lawn
Because robotic mowers are designed to mow more frequently, clippings are smaller and decompose more quickly. Compared to mowing once or twice a week with a gas-powered mower, the robotic mower’s reduced length of cut creates less stress to grass and helps to promote a healthier, denser lawn.

Efficiency and energy cost savings
Consider the seasonal energy use and cost for mowing the average Nebraska lawn, which is reported to be 13,921 square feet according to Today’s Homeowner, the #1 syndicated home improvement TV show in the U.S. Over the course of a seven-month mowing season, a randomly selected robotic mower clips the lawn every other day and consumes almost 62 kilowatt-hours (kWh) of electricity. At last mowing season’s average cost of 11.56¢ per kWh in Nebraska, the total is about $7.14.

In comparison, this size of lawn could be trimmed with a 21-inch, gas-powered mulching push mower every third day. By the end of the same seven-month mowing season, the push mower will have used 35½ gallons of gasoline and required 71 hours of someone’s time to push it. If gas were $3 per gallon, that comes to $106.50. You can determine what 71 hours of free time is worth.

Safety
Cutting on slopes with push or riding mowers always presents a safety concern. Robotic mowers can typically mow slopes of 20-35 degrees, with some tackling even steeper grades. More advanced models have sensors that can detect obstacles and maneuver around them or even automatically stop the blades when the mower is lifted.

With a little luck, your neighbor’s early morning lawncare routine will never disrupt your morning tranquility again. Who knows? By now, maybe you’re interested in a robotic mower.
