See The Breakdown
See how our mower stacks up against the competition with no gas costs, no maintenance costs, and lower up front costs.
Consider the Cost: With a national average of $3.50 per gallon of gasoline being used for 4-5 hours of mowing per day (an average during mowing season), plus the additional $300-$500 in annual maintenance costs per gas mower, the cost of running your business is rising every day. When you see the numbers, the Oso 21-Inch All-Electric Lawn Mower almost pays for itself.
