Lease vs Buy a Mower: The Math That Actually Decides It

The dealer is holding a demo unit and the payment is $300 a month.

That is how most of these decisions actually start. Not with a spreadsheet. With a machine you want, a number that sounds manageable, and a salesman who is genuinely nice and genuinely not on your side of the table.

Here's the thing. "Lease or buy" is the wrong first question. The right one is what a machine costs you per hour of work it does, and almost nobody in this trade runs that number before signing.

Let's run it.

Three things get called leasing, and only one of them is a lease

Before any math, know what you are actually being offered, because dealers use these words loosely and the difference decides your taxes and your exit.

A true lease. You rent the machine for a term. At the end you hand it back, renew, or buy it at whatever it is worth then. You never own it. Payments are usually lower, and you are typically paying for the machine's depreciation during its best years.

An equipment finance agreement. This is a loan wearing a lease costume. You own the machine from day one and the lender holds a lien until you pay it off. It gets called a "lease" constantly. It is not one, and it is usually the better deal if you plan to keep the equipment.

Rent-to-own. Common at dealers on stand-ons and zero-turns. You rent by the month and some or all of the rent applies toward purchase if you buy it out. Expensive if you go the distance, genuinely useful if you are unsure whether a machine earns its keep.

Ask one question and the fog clears: at the end of this term, who owns the machine and what do I owe to keep it? If the salesman needs to check, you are not being sold a lease.

The only number that matters is cost per hour

A mower does not cost $12,000. It costs some amount per hour that it runs, and that is the number you can actually compare against a payment, against a rental, and against what you charge.

Here's the math. Use your own numbers, these are just the shape of it.

Say a stand-on at $12,000. You put 400 hours on it a season and keep it five seasons. That is 2,000 hours of work. Say it is worth $3,000 when you sell it.

$12,000 minus $3,000 of resale is $9,000 of ownership cost, spread across 2,000 hours. That is $4.50 an hour, before you fix anything.

Add maintenance. Blades, belts, filters, oil, a spindle or two, a set of tires. Call it $1.50 an hour across the life. Now the machine costs you about $6.00 an hour to own and run.

Now price the lease against it. $300 a month for 36 months is $10,800. If you are running 400 hours a season, three seasons is 1,200 hours, so that machine cost you $9.00 an hour and you own nothing at the end.

On those numbers buying wins by about $3.00 an hour. On 400 hours a season that is $1,200 a year.

But look at what that comparison assumes. It assumes the machine actually lasts five seasons, that you had $12,000 you could part with, and that a $2,800 repair in year four does not land in a month you could not absorb it. Change any of those and the answer changes. That is the honest version, and it is why "just buy it, leasing is throwing money away" is bad advice given confidently.

When buying wins

You keep equipment a long time. The math above is entirely driven by how many hours you spread the purchase across. A machine you run for six seasons is dramatically cheaper per hour than the same machine run for three. Operators who buy well and maintain religiously win on cost, every time.

The work is steady and predictable. If the machine is booked all season every season, ownership is the cheaper way to hold it.

You have the cash and it is not your only cash. This is the real test, and it comes back at the end of this post.

You are good with a wrench, or you have a guy. Ownership means you carry the repair risk. That is a bargain if a broken deck spindle costs you a Saturday afternoon and a $90 part. It is a different bargain if it costs you a week and a dealer bill.

When leasing or financing wins

Cash is the binding constraint. A slow spring, a client who pays at 60 days, a payroll you have to make. Twelve thousand dollars leaving the account in March is a real risk to a business that a $300 payment is not. Preserving cash is a legitimate business reason, not a failure of discipline.

You are testing a machine or a service line. Thinking about adding treatment work or a bigger install side and unsure the volume is there? Rent or rent-to-own the machine for a season and let the work prove itself. Buying a machine to service work you hope shows up is how equipment ends up sitting behind the shop.

You want to be under warranty, always. Some operators deliberately turn machines over every two or three seasons so they are never the one paying for a hydraulic failure. That costs more per hour and buys predictability. If your season has no room for a truck-and-machine week, predictability may be worth the premium.

Growth is the bottleneck, not cost. If one more machine means one more crew and one more crew means real revenue, the financing cost is small next to the work it unlocks.

The tax angle, minus the myths

You will hear "buy it before December 31st and write the whole thing off." There is something real underneath that, and it is oversold every year.

Section 179 lets a business deduct the cost of qualifying equipment in the year it is placed in service, instead of depreciating it over several years, subject to annual limits set by the IRS. The rules and the limits are laid out in IRS Publication 946.

Three things get left out of the version you hear at the dealership:

• A deduction is not a rebate. Deducting $12,000 does not save you $12,000. It reduces taxable income, so what you save is roughly the equipment cost times your effective tax rate. You still spent the money.
• It only helps if you have profit to offset. In a thin year the deduction is worth much less, and you may be better off depreciating over time.
• Lease treatment is different. With a true lease, payments are generally an operating expense. With a purchase or a finance agreement, you own the asset and the depreciation rules apply. How the contract is written changes the answer.

Talk to your accountant before the machine, not after. This is a 20-minute phone call that regularly changes which option is correct, and it is the cheapest part of the whole transaction. Anyone telling you the tax angle alone justifies the purchase is selling something.

The question that actually decides it

Strip away the tax talk and the cost-per-hour math and it comes down to one thing.

If this machine broke tomorrow and the repair was $2,500, would that be an annoyance or an emergency?

Annoyance, meaning you would grumble and pay it: buy. Ownership is cheaper per hour and you can carry the risk.

Emergency, meaning you would be moving money around and delaying something else: lease, finance, or rent. You are not buying a machine at that point, you are buying the ability to keep operating when something goes wrong, and that is worth paying for.

Grounds maintenance is seasonal, weather-dependent work by nature, according to the Bureau of Labor Statistics. Seasonal revenue and a large single outlay in the wrong month is how good businesses end up borrowing at bad rates in July.

You cannot answer this without knowing what your jobs make

Here is the uncomfortable part. Every number above depends on knowing your real hours and your real margin, and most operators are estimating both.

If you do not know that a property drifted from 45 minutes to 70 over three seasons, you do not know your true hours per machine. If you do not know which accounts run thin once labor and materials are counted, you cannot tell whether a second machine adds profit or just adds capacity for work that was not paying anyway.

At $65 an hour, 30 minutes of uncounted drift on one weekly account is about $1,100 across an eight-month season. Ten of those accounts is $11,000, which is most of the mower in the example above, sitting in work you already do.

That is what job costing for landscapers is for, and it is the input this decision actually runs on. Small businesses already spend 10 to 15 hours a month on billing and bookkeeping, according to SCORE, so the answer is not a second spreadsheet. It is having the number fall out of the work you already schedule and bill. The profit margin post covers what a healthy number looks like once you have it.

What to do this week

• Get your real hours. Not the estimate. What the machine actually ran last season and what the crew actually spent on the properties it served.
• Run cost per hour on both options. Purchase price minus expected resale, divided by hours over the life you will actually keep it, plus maintenance. Then total lease payments divided by hours over the term.
• Ask the dealer the ownership question. At the end of this term, who owns it and what do I owe to keep it? Get it in writing.
• Call your accountant before you sign. Twenty minutes, before the purchase, not in April.
• Answer the $2,500 question honestly. It matters more than the other four combined.

Frequently asked questions

Is it better to lease or buy a commercial mower? Buying is usually cheaper per hour if you keep equipment for several seasons, have the cash without straining, and can absorb a repair bill. Leasing or financing is better when cash is tight, when you are testing a new service line, or when you want to stay under warranty and avoid repair risk. Run cost per hour on both before deciding, and use your own hours rather than a rule of thumb.

How do you calculate the cost per hour of a mower? Take the purchase price, subtract what you expect to sell it for, and divide by the total hours you will run it over the years you will keep it. Then add maintenance per hour. For a lease, divide total payments by the hours you will run during the term, and remember you own nothing at the end.

Can you write off a mower on your taxes? Section 179 lets a business deduct the cost of qualifying equipment in the year it is placed in service, subject to annual IRS limits, and a true lease is generally treated as an operating expense instead. A deduction reduces taxable income rather than refunding the purchase price, and it only helps if you have profit to offset. See IRS Publication 946 and talk to your accountant before you buy.

Is rent-to-own a good idea for landscaping equipment? It is expensive if you go the full term, and genuinely useful when you are not sure a machine or a new service line will earn its keep. Renting for a season while the work proves itself costs less than owning a machine that sits behind the shop.

How many hours does a commercial mower last? It depends entirely on the machine, the maintenance, and the conditions it runs in, and any specific number you see quoted is a generalization. What matters for this decision is the number of hours you personally expect to get out of it, which your own service history and your dealer are the right sources for.

The honest version

There is no universally correct answer, and anyone giving you one without asking about your cash position is guessing.

Buy when you keep equipment a long time and a surprise repair is an annoyance. Lease or finance when cash is the constraint, the work is unproven, or downtime would hurt more than the premium costs.

And whichever way you go, get your real hours and your real margins first. The machine is not the decision. The decision is whether the work it does is priced to pay for it.
