What Does Your Lawn Mowing Equipment Actually Cost Per Hour?

⚡TL;DR: Key Takeaways

• Your equipment costs $3–$10+ per hour to run, and most operators have no idea where they sit in that range
• The three components: depreciation (purchase price spread over the machine's life), fuel consumption, and maintenance (servicing, blades, belts, repairs)
• A typical zero-turn costs $7–$10 per hour. A push mower costs $2–$4 per hour. String trimmers and blowers add another $1–$2 per hour on top
• On a full trailer of equipment, you're burning through $8–$13 per equipment hour before you've paid yourself, fuelled the truck, or covered insurance
• If you're not building these numbers into every quote, you're subsidising your customers out of your own pocket

Ask most lawn care operators what their equipment costs per hour and you'll get a blank stare. Or a guess. Or "just fuel."

It's not just fuel.

Every hour your mower runs, it's losing value. Getting closer to the next service. Blades dulling, belts stretching, bearings wearing. That's real money ticking away while you mow, and if it's not in your pricing, it's coming straight out of your margin.

This guide breaks down exactly what every piece of equipment on your trailer costs per hour: depreciation, fuel, and maintenance. So you can stop guessing and start quoting with real numbers behind you.

Most operators think about equipment costs in big, painful lumps. The $12,000 hit when you buy the zero-turn. The $400 service bill. The $600 set of blades and belts.

What they don't think about is the per-hour cost. And that's the number that actually matters for quoting.

Here's why: you don't charge customers in lump sums. You charge them per job. Each job uses your equipment for a certain number of hours. If you don't know what those hours cost, you can't know what the job costs. And if you don't know what the job costs, you're guessing your price.

$8–$13/hr

That means on a 45-minute residential mow, you're spending $6–$10 in equipment costs alone. Before fuel for the truck. Before insurance. Before you've paid yourself a cent.

Most operators don't know their true costs. And it's costing them.

When operators tell us they charge $65 an hour but only "clear" $30 after costs, the gap is almost always equipment. Fuel they can see. Insurance they pay monthly. But depreciation and maintenance are invisible until the machine dies or the repair bill lands.

Every piece of equipment has three costs that tick over every hour it runs. Miss any one of them and your numbers are wrong.

1. Depreciation

Depreciation is the biggest cost and the one most operators ignore completely.

Your $12,000 zero-turn is not worth $12,000 after a year of commercial use. It's not worth $12,000 after a month. Every hour it runs, it loses value. When it eventually dies or you replace it, you need that money again to buy the next one.

The calculation is simple:

Depreciation per hour = Purchase price / (Expected life in years × Hours per year)

A $12,000 zero-turn that lasts 5 years at 1,000 hours per year costs you $2.40 per hour in depreciation. That's $2.40 per hour ticking away whether you account for it or not.

2. Fuel

Fuel is the cost everyone tracks, because you physically watch it leave your wallet at the pump. But most operators track it at the truck level ("I spent $200 on fuel this week") rather than per machine.

Different equipment burns fuel at very different rates:

• A zero-turn ride-on burns 3–6 litres per hour depending on engine size and terrain
• A self-propelled walk-behind burns 1–2 litres per hour
• A push mower burns 0.5–1 litre per hour
• Two-stroke equipment (trimmers, blowers, edgers) burns 0.3–0.8 litres per hour

At current fuel prices, that's anywhere from $0.50 to $10+ per hour per machine.

3. Maintenance

Maintenance covers everything that keeps the machine running between purchase and replacement:

• Regular servicing: oil, filters, spark plugs (every 50–100 hours)
• Blade sharpening and replacement: the most frequent cost
• Belt and spindle replacement: especially on zero-turns
• Unplanned repairs: the ones that always come at the worst time
• Consumables: trimmer line, air filters, grease

A good rule of thumb: budget 10–15% of the purchase price per year for maintenance on commercial equipment. Some years it's less. Some years a hydro pump goes and it's a lot more. The annual average is what matters.

Here's what it actually costs to run the most common lawn care equipment, broken down by the three components.

Zero-turn ride-on mower

The workhorse of commercial lawn care. Fastest ground coverage, highest purchase price, highest running costs.

A zero-turn at $9 per hour on a 45-minute mow costs you $6.75 in equipment alone. On a $70 job, that's nearly 10% of the revenue gone before you've done anything else.

For a deep dive into zero-turn specific costs, see Zero Turn Mower Running Costs: The Real Numbers.

Self-propelled walk-behind mower

The mid-range option. Slower than a zero-turn, cheaper to run, and necessary for properties where ride-ons can't go: narrow gates, steep slopes, tight spaces.

Push mower

The entry-level option. Cheapest to buy and run, but the slowest and most physically demanding. Most operators keep one as a backup or for small, tight properties.

Cheap to run, but you'll feel it in your knees. Most operators keep one on the trailer for the jobs where the zero-turn won't fit through the gate.

Your mower is the biggest equipment cost, but it's not the only one. Most operators carry a trimmer, an edger, and a blower. They all cost money per hour too.

String trimmers (whipper snippers / weed eaters)

Blowers

Edgers

If you run a dedicated edger (rather than using your trimmer for edging), add another $0.50–$1.00 per hour on top.

The full trailer adds up

$8–$13/hr

Most operators think of equipment as a sunk cost. "I already bought it." But every hour those machines run, you're spending real money. If that money isn't in your quotes, you're slowly bleeding cash.

The formula is the same for every piece of equipment. Three numbers, one calculation.

Calculate equipment cost per hour

1

Calculate depreciation per hour

Depreciation = Purchase price ÷ (Expected life in years × Annual hours of use)

Example: $12,000 zero-turn, 5-year life, 1,000 hours per year = $2.40 per hour.

If you bought it used, use the price you paid. If you're financing, use the total amount you'll pay including interest. The point is: how much money do you need to set aside per hour so you can afford the replacement when this one dies?

2

Calculate fuel cost per hour

Fuel cost = Litres per hour × Price per litre

Check your machine's spec sheet for fuel consumption, or track it yourself. Fill the tank, run it for a known period, fill it again, and measure how much it took.

For US operators: convert to gallons per hour × price per gallon.

3

Calculate maintenance cost per hour

Maintenance = Annual maintenance spend ÷ Annual hours of use

If you're in your first year, estimate 10–15% of the purchase price. After a couple of years, use your actual spending on services, blades, belts, parts, and repairs.

See Lawn Mower Service Schedule & Costs for a complete breakdown of what maintenance actually costs per machine type.

4

Add them together

Equipment cost per hour = Depreciation + Fuel + Maintenance

Do this for every machine on your trailer. Add them all up. That's the equipment cost ticking away every hour you're on a property.

Here's what that looks like on a real trailer. A typical solo operator's equipment lineup, costed per hour.

On a typical day where this operator runs the zero-turn for 6 hours, the trimmer for 2 hours, and the blower for 1.5 hours, that's:

• Zero-turn: 6 hrs × $7.10 = $42.60
• Trimmer: 2 hrs × $1.20 = $2.40
• Blower: 1.5 hrs × $0.90 = $1.35

Total equipment cost for the day: $46.35

That's nearly $50 a day in equipment costs, or about $240 per week, or roughly $10,000–$12,000 per year. If that's not built into your pricing, it's coming directly out of your wage.

Buying the cheapest mower on the market feels like saving money. In practice, it often costs more per hour.

A $4,000 residential-grade zero-turn might last 2 years under commercial use. A $12,000 commercial-grade machine lasts 5. Run the numbers:

• Cheap mower: $4,000 ÷ (2 years × 800 hours) = $2.50/hr in depreciation
• Commercial mower: $12,000 ÷ (5 years × 1,200 hours) = $2.00/hr in depreciation

The expensive mower is cheaper per hour. And that's before you factor in that residential machines need more frequent repairs, break down during the work day (costing you jobs), and mow slower (reducing your hourly revenue).

This applies to every piece of equipment. Commercial trimmers, commercial blowers, commercial edgers. They all cost more upfront and less per hour than their residential equivalents.

Here's where all of this becomes money in your pocket (or money out of it).

Two operators quote the same 45-minute lawn at $65. Same charge, same customer. But look at the difference in what they actually keep.

Operator A: knows their numbers

• Equipment cost per hour: $11 (full trailer)
• Equipment cost for this job (45 min): $8.25
• Remaining after equipment: $56.75
• Knows this before quoting. Prices accordingly.

Operator B: "just fuel"

• Thinks equipment costs are "just fuel": ~$4
• Thinks they're keeping $61 after equipment
• Actual equipment cost per hour: $11 (same gear, just not tracking it)
• Actually keeping: $56.75. $4.25 less than they think, every single job

Over 8 jobs a day, Operator B is $34 short of where they think they are. Over a 5-day week, that's $170. Over a year, it's close to $8,000 in margin they thought they had but didn't.

Neither operator is charging differently. The only difference is that Operator A knows the real number and builds it into their pricing decisions. Operator B finds out at the end of the year when the bank account doesn't add up.

Every contractor's been burned by underquoting. The ones who survive are the ones who learn to count everything.

Equipment cost per hour isn't static. It changes over the machine's life.

In the early years, depreciation is the dominant cost and maintenance is low. As the machine ages, depreciation slows down (it's already lost most of its value) but maintenance ramps up. At some point, the rising maintenance costs push the total cost per hour above what a new machine would cost.

That crossover point is when it's time to replace, not when the machine breaks down catastrophically and you're stuck without a mower on a Tuesday morning with 8 jobs booked.

Track your cost per hour over time. When it starts climbing consistently, especially when unplanned repairs are increasing, run the numbers on a replacement.

You don't need to get this perfect on day one. You need to get started.

Here's what to do this week:

1. List every piece of equipment on your trailer. Mowers, trimmers, blowers, edgers, chainsaws. Everything that earns you money.

2. Write down three numbers for each one. What you paid, how long you expect it to last, and how many hours per year you use it.

3. Estimate fuel consumption. Check the manufacturer's spec or track it yourself for a week.

4. Estimate annual maintenance. Add up last year's servicing, repairs, blades, belts, and parts. If you're new, start with 10–15% of the purchase price.

5. Run the calculation. Depreciation + fuel + maintenance = your cost per hour per machine.

Or skip the spreadsheet and use the Equipment Cost Per Hour Calculator. Plug in your machines and it does the maths for you.

Once you know your equipment cost per hour, build it into every quote. Not as a separate line item. Your customer doesn't need to see it. But behind the scenes, it's part of your cost base. It's the reason you charge $70 instead of $55. It's the difference between a profitable business and a busy one that makes no money.
