Propane Lawn Mower Reviews and Case Study Highlights

Municipalities across the nation are turning to propane to power their mowers. Lawn mower fleets fueled by propane save taxpayer dollars by becoming more efficient. In addition to improved efficiency, municipalities using propane mowers also experience the positive environmental impacts associated with clean-burning fuel. Here are a few propane reviews and case study highlights from cities that are taking advantage of the benefits of propane.

City of Columbus, Ohio

Columbus, Ohio recognized the need to implement new, emission-reducing technology to meet tightening EPA regulations. After considering several options, the city adopted 14 propane-powered Exmark zero-turn mowers as part of their Green Fleet Action Plan.

“We researched many green alternatives, and propane came out as the easiest and most affordable option to put into practice. Adopting propane was a turnkey solution because there isn’t much downtime for refueling. Propane mower performance is similar to that of conventional fuels. You don’t lose any horsepower, yet they’re much quieter, and you can refuel in about 30 seconds.”

Craig Seeds
Parks and Forestry Administrator, City of Columbus

Fueled by propane, here’s what the City of Columbus found:

  • Propane-powered mowers reduce greenhouse gas emissions by more than 15 percent and carbon monoxide emissions by more than 40 percent compared with gasoline-fueled mowers.
  • Columbus saves about 50 cents per gallon on fuel costs with propane compared to gasoline.
  • Propane reduces unpleasant gasoline fumes making the park visitors’ experience more enjoyable.

“We initially sought out propane because it’s a clean fuel predominantly made in the U.S., and it fit into our existing sustainability goals. The city operates an additional 28 mowers comparable to its Exmark versions on conventional fuels, but due to the positive results we’ve experienced, we hope to replace them with propane as they reach their eight-year replacement interval.”

Miami-Dade County Parks, Recreation, and Open Spaces Department, Florida

The Miami-Dade County Parks, Recreation, and Open Spaces Department maintains many green spaces in the county’s special tax districts, including 42 parks, 122 residential communities, and too many sports fields to count. The municipal department turned to propane for a more efficient way to meet the demands of southeast Florida’s year-round cutting season.

The department did a study comparing gasoline and propane mowers. Here’s what they found:

  • Propane increased productivity and reduced costs. Propane mowers could cut more grass, faster, and for less money.
  • Propane mower fleets operate with a lower cost-per-hour of operation, compared to gasoline. 
  • More productive propane mowers helped free up crews’ time to do more landscaping.
  • Maintenance costs were greatly reduced. The clean, ethanol-free propane kept mower engines free from contamination and filters from clogging. In the field, operators noticed it was rare for the machines to break down, too.

“We saw that a transition to propane could result in a positive public relations opportunity for the county because of propane’s clean emissions profile.”

Gil Delgado
Sports Turf and Landscape Division Chief, Miami-Dade County

Delgado painted the county’s first propane mower green with the department logo so that residents would identify the county with green energy. The mower was brought to as many events as possible to make the public aware of the county’s plans to operate propane mowers and to build public trust. People were curious and excited about the machines.

“One propane cylinder can power a day and a half of mowing, and refueling is as simple as swapping out an empty cylinder for a full cylinder. The operators can carry an extra propane cylinder to a site rather than leaving to fill up gasoline tanks at a filling station during the day. Before switching to propane, it could take 15 minutes each way to get to and from filling stations. Along with increasing crew productivity, fuel savings are another reason the department has continued using propane mowers for nearly a decade. It’s advantageous compared to the costs of gasoline and diesel, especially when considering that the county has a year-round growing season.”

Landscape Technician Supervisor, Miami-Dade County

Propane is a versatile and efficient fuel that delivers many benefits to landscapers and commercial mowing businesses across the country and right here in Missouri. Propane is consistently less expensive than gasoline at the pumps. It eliminates the risk of fuel leaks or spills and naturally prevents fuel from walking off job sites. All of these savings allow commercial landscaping businesses to provide more competitive bids and win more jobs as a result.
