Lease vs. buy a commercial lawn mower: Cost worksheet

A low monthly payment can make a commercial mower lease look inexpensive. A future trade value can make buying look equally attractive. Neither number answers the contractor’s real question: Which proposal puts the right machine in service at an acceptable total cost and risk over the period the business will actually use it?

Use the worksheet below with signed dealer and lender proposals—not advertised rates or assumptions. It keeps cash flow, maintenance, downtime, contract restrictions, and end-of-term value visible without pretending there is one universal lease-versus-buy answer.

Start with an apples-to-apples mower comparison

Compare the same operating capability on both sides. Record the exact mower model, engine or battery configuration, deck, collection system, attachments, tires, warranty, training, delivery location, and in-service date.

If the machines differ, note the operational effect instead of comparing payments alone. A narrower deck, missing bagger, or incompatible fleet parts can change route time and downtime exposure. Use our commercial zero-turn mower guide to define the required capacity before requesting quotes.

Choose one comparison period based on the expected holding period or lease term. Use the same start date and number of months for every option. Also record expected annual operating hours from your own route history; do not substitute a dealer’s generic use estimate.

Copy each proposal into the worksheet

Create one column per quote and preserve the proposal date and version. Mark a cell not included rather than leaving it blank.

Acquisition input	Lease quote	Purchase or finance quote
Cash due at signing or order
Refundable and nonrefundable deposits
Purchase price or capitalized amount
Payment amount, count, and due dates
Interest rate or financing charge shown
Documentation, origination, or acquisition fees
Sales, use, property, registration, or other quoted taxes and fees
Freight, setup, delivery, and operator training
Required attachments and installation
Required insurance and deductible
Warranty term and covered labor, parts, pickup, and transport
End-of-term purchase option or required final payment
Return, inspection, transport, or disposition charges

Ask the dealer or lender to explain every line you cannot reproduce from the signed documents. Confirm whether payments begin at signing, delivery, or acceptance.

Build the cash-flow comparison

First, list cash outflows by month or quarter.

Then calculate an undiscounted cash total for the stated comparison period:

Lease cash outflow = due-at-signing cash + scheduled payments + mandatory fees, insurance, delivery, and attachments + owner-paid operating costs + expected excess-use, condition, return, and termination costs + buyout only if the plan includes exercising it.

Financed-purchase cash outflow = down payment + scheduled principal-and-interest payments + mandatory fees, insurance, delivery, and attachments + owner-paid operating costs + sale or trade costs − expected net sale or trade proceeds received within the comparison period.

For a cash purchase, replace the down payment and financing payments with the actual delivered purchase price.

Do not subtract a trade estimate without stating when the cash is expected and what could reduce it. If your accountant uses present-value analysis, use the business’s approved discount rate.

Add maintenance, repairs, and downtime

The party making the payment is not always the party paying to keep the mower productive. For each proposal, identify responsibility for:

• Preventive maintenance, pickup, and shop transport
• Blades, belts, tires, batteries, filters, fluids, and other consumables
• Damage, abuse, wear items, and repairs excluded from warranty
• Loaner availability and the conditions or time limits attached to it
• Diagnostic labor, travel, freight, and warranty deductibles
• Required dealer service and documentation needed to preserve coverage

Exmark advises using the maintenance schedule in the mower’s owner manual and warns that neglected maintenance can produce avoidable downtime and repairs. Build costs from the exact machine’s schedule and your labor or dealer rates. Our commercial mower maintenance checklist shows how to organize shift, hour-meter, and seasonal work without inventing universal intervals.

Record downtime as a separate operating input:

Downtime burden = actual contribution lost during unavailable production + temporary replacement or rental cost + documented crew and transport disruption.

Avoid counting the same lost work twice. If jobs were completed later without losing contribution, record the overtime, rescheduling, or customer-service cost that actually occurred instead of claiming the full route revenue.

Read the restrictions before valuing flexibility

A lease can transfer some residual-value risk, but the contract may limit use or return. A purchase leaves the contractor responsible for resale timing and condition.

Review these terms side by side:

• Annual and total hour limits, meter verification, and excess-use charges
• Approved operators, locations, applications, and attachments
• Maintenance records and required service providers
• Return condition, tire or blade wear, damage standards, and inspection process
• Early-termination formula and remaining-payment obligation
• Renewal timing, month-to-month terms, and notice deadlines
• Purchase-option price, timing, fees, and whether the option is guaranteed
• End-of-term transport, cleaning, de-identification, and storage responsibility
• Ownership, lien release, title documents, and permission to sell or trade

Keep tax and accounting questions out of the sales pitch

The SBA recommends evaluating whether to buy or lease needed business assets and using a cost-benefit analysis over a specified period. That operating comparison should be completed before any claimed tax benefit is treated as decisive.

The IRS says an equipment agreement must be evaluated as either a lease or a conditional sales contract based on the agreement and the facts and circumstances; no single test always applies. IRS Publication 946 separately explains depreciation requirements for qualifying owned business property, including when property is placed in service.

Give a qualified tax professional the complete proposal and ask:

1. How will this specific agreement be classified for federal, state, and local purposes?
2. Who is treated as the owner, and when is the mower placed in service?
3. Which payments, fees, taxes, and improvements are expenses or capitalized costs?
4. How do business-use percentage, entity type, accounting method, and existing elections affect treatment?
5. What records and depreciation, disposition, or recapture calculations may be required?

Do not enter a universal deduction or tax savings in the worksheet. Enter only an estimate prepared for the business by its tax professional, label the assumptions, and keep a version that shows the decision before tax effects.

Run four sensitivity checks

Replace one assumption at a time using your records or contract terms:

1. Utilization: Run lower and higher annual mower hours. Check lease-hour charges and whether ownership costs are spread across enough productive use.
2. Downtime: Add a realistic repair event using your actual rental, transport, and route-recovery costs. Compare warranty and loaner terms.
3. Holding period: Test an earlier replacement and a longer hold. Include early termination on the lease side and remaining loan balance, repairs, and sale timing on the purchase side.
4. End value: Lower the estimated trade or resale proceeds and increase sale costs. Separately test the contractual lease buyout or return charges.

If a small change reverses the result, the decision is sensitive. Negotiate the exposed term or choose the option with the risk the business can control.

Use a quote-comparison checklist

Before signing, confirm that you have:

• Matched mower capability, accessories, warranty, delivery, and training
• Used the same comparison dates and actual expected operating hours
• Scheduled every payment and required fee
• Assigned maintenance, consumables, repairs, transport, and downtime costs
• Read use limits, return standards, early termination, renewal, and buyout language
• Documented insurance requirements and exclusions
• Supported the purchase option’s net resale estimate
• Had tax and accounting questions reviewed independently
• Recorded the winning option, rejected option, assumptions, sensitivity results, and approver

If the current mower is being replaced because its drive weakens after warm-up, complete the hydrostatic mower hot-power diagnosis first. A measured repair-versus-replacement record prevents an acquisition decision based on a misdiagnosed belt, cooling, or service issue.

Make a decision the business can audit

The better acquisition is not automatically the one with the lowest payment. Choose the option that meets required capacity, fits the business’s cash constraints, and remains acceptable under the likely sensitivity cases.

Save the signed quotes, completed worksheet, assumptions, maintenance responsibilities, accountant’s advice, and approval in the mower’s asset record. A clear decision record turns the next replacement from a sales conversation into a repeatable fleet process.
