Let’s break down the cost of operation for an electric mower vs. the gas counterpart.
From some quick googling it seems the cub cadet zero turn uses 1.8 gallons of fuel per hour. Let’s round this down to 1.5GPH. Fuel cost in this area is $3.50/gallon, so
1.5GPH x $3.50 = $5.25/hour
Our electrified zero turn mows for approximately 1 hour on a 4KWH battery pack. The electricity price in this area is $.13/KWH, so
4KWH x $.13 = $.52/hour
But the electric zero turn costs more upfront than the gas version. The total part cost breakdown is as follows
3x Enerdel ME330-049 Energy @$480/ea = $1460
ME-1004 Double brush 48v motor = $525
Soliton Jr. Motor controller = $1750
PMP-450 pump, radiator, tubing = $250
——-Grand total——- $3985 dollars
So the operational cost difference is $5.25 – $.52 = $4.73/hour
And the payback time for the conversion based purely on fuel cost savings is…..
$3985 / $4.73 = 842.49 hours of operation
