Ask any commercial landscaping operator what their biggest cost is, and most will say labor. Ask a few follow-up questions, and fuel usually comes up second. But dig into the actual numbers on a fleet of gas-powered mowers, and a more complicated picture emerges.
The sticker price on a piece of equipment is only the beginning. What follows is months and years of fuel bills, maintenance appointments, downtime, and depreciation that quietly erode your margins. Most operators never total it up. They should.
Key Numbers at a Glance
$3.50/gal Average U.S. gas price
4-6 hrs Typical daily runtime per mower
$300-$500 Annual maintenance cost per mower
The fuel math nobody does
A commercial walk-behind or zero-turn mower burns roughly 1 to 1.5 gallons of gas per hour. At five hours of daily runtime and $3.50 per gallon, that works out to between $17.50 and $26.25 per mower, per day, before a single blade of grass is cut. Across a five-day week, that’s up to $525 per mower per month in fuel alone. Multiply that across a fleet of ten mowers and you’re looking at over $63,000 a year going straight into the gas tank.
And that’s at current prices. Fuel costs have swung dramatically over the past few years. Operators who built pricing models around $2.50 gas got caught off-guard when prices climbed to $4.00. That volatility isn’t going away, and every time it spikes, your margins take the hit.
“The cost of fuel isn’t a fixed line item. It’s a variable you can’t control, and that unpredictability compounds over time.”
Maintenance: the cost that sneaks up on you
Gas engines are mechanically complex. Air filters, spark plugs, oil changes, belts, carburetors, fuel lines. Each one is a small cost on its own, but together they add up to $300 to $500 per mower annually under normal commercial use. And that’s if nothing goes wrong.
When something does go wrong, a blown engine or a cracked fuel line mid-season, the costs compound fast. You’re not just paying for the repair. You’re paying for the crew time lost while the machine is down, the jobs that get pushed back, and the customer satisfaction that quietly erodes when crews show up undermanned.
Downtime is a cost too
This one rarely shows up in a budget spreadsheet, but it’s real. Every hour a mower sits in a shop waiting for a part is an hour a crew isn’t working at full capacity. In peak season, that can mean missed contracts or crews working overtime to catch up, both of which eat directly into profit.
Electric equipment has dramatically fewer moving parts. No combustion engine. No exhaust system. No oil to change. The mechanical complexity that makes gas mowers prone to breakdowns simply isn’t there, which means less time in the shop and more time on the job.
What to do about it
The answer isn’t to absorb the costs and hope fuel prices stabilize. It’s to remove the variables you can control. Electric commercial mowers eliminate fuel costs entirely, and when combined with AI-driven operation, they also reduce the labor overhead involved in supervising equipment across large properties.
The transition doesn’t have to happen overnight. Many operators start by electrifying part of their fleet, measuring the savings, and expanding from there. The key is getting a real number on what your gas-powered equipment is actually costing you today, across fuel, maintenance, and downtime.
Run that number. You might be surprised.
