Battery-operated mower takes away labor, adds 'cool factor' to lawn mowing
By: Sharon Dowdy for CAES News
To some, mowing the lawn is an enjoyable, almost therapeutic, task. To others, it’s a task they dread. For those, a new battery-operated mower, much like the popular Rumba vacuum cleaner, may be the product of your dreams.
“The ‘automower’ actually isn’t a new concept. They’ve been used in Europe for a few years, but they haven’t been widely adopted in the U.S. to this point,” said University of Georgia Cooperative Extension Turfgrass Specialist Clint Waltz.
Waltz is currently using an “automower” on the lawn just outside the new UGA Turfgrass Research Facility on the UGA Griffin campus. The Husqvarna mower is on loan from Georgia sod producer Super-Sod, so Waltz can observe and evaluate the concept of “continual” mowing, he said.
Since putting the futuristic-looking mower to work the third week of August, Waltz thinks the mower has “great potential” for residential and commercial lawncare. The battery-powered device sets out to mow and returns to its charger when it needs “refueling.”
When it comes to environmental impact, the “automower” doesn’t use fossil fuels and doesn’t stir up dust like conventional mowers. Maintenance costs do not include oil changes or new spark plugs; it only needs new blades every three to four months at a cost of about $20.
With labor being the biggest challenge in the landscape industry today, the “automower” may fill a need, Waltz said.
“When labor becomes difficult to find, or too expensive, innovation occurs. The ‘automower’ doesn’t stay home from work because of a case of brown bottle flu or complain to the department of labor about its continuous working schedule,” Waltz said.
The small mower uses several tiny razor blades, similar to a double-sided utility knife, to cut grass. This “clean” cut of the leaf blade reduces loss of water and minimizes the opening for disease, he said. There’s no scalping of the turf, therefore, it’s a healthier grass plant
“In tight areas of the lawn where a conventional mower may have to make multiple passes, compacting the soil and increasing traffic and wear, the ‘automower’ can mow more efficiently and decrease compaction,” he said.
The auto-mower also reduces safety concerns for drivers of conventional mowers when mowing steep slopes or hard-to-mow areas. And, it can mow areas normally cleared with string trimmers.
Since the mower removes no more than a third of the leaf at a single mowing, no thatch or surface clumps accumulate on the lawn.
“This method of mowing also doesn’t overwhelm the soil microbes, making them more efficient at returning organic matter to plant-available nutrients,” Waltz said. That simply means there could be less need for fertilizer.
So far, Waltz thinks the “automower” would be perfect for people who long for that “just mowed look.”
“We are in a quality business. Turfgrass has to look good and perform,” he said. “Continual mowing removes seedheads more regularly or prevents them from fully developing. This alone leads to improved appearance because seedheads, or seed stalks, give a ‘stemy’ look that detracts from the lawn’s appearance.”
Some “automower” models come with lights that could act as a wildlife deterrent, Waltz said.
“The random mowing pattern may act as a deer deterrent within the landscape. It’s not substantiated, but there have been comments that landscapes with the ‘automower’ have fewer moles and voles,” he said.
For now, the UGA Extension specialist is observing the device. “Potential research trials could develop such as the automower’s impact on disease, fertility and other management practices,” he said. “For now, it’s doing its job mowing and causing some second glances. It does bring with it a cool factor.”
