Plan an equipment purchase or repair decision
Define the workload and permitted operating conditions, then price the complete usable setup. Compare repair, purchase or rental against the same job and time period. A headline price, engine size or broad service-life estimate cannot settle the decision by itself.
Two ownership decisions
- Gas or battery equipment: price the whole working session
- Repair or replace equipment: compare diagnosed costs and scope
Build a comparable total
| Choice | Include |
|---|---|
| New machine | Required pack / charger, accessories, delivery and setup |
| Repair | Diagnosis, parts, labor and unresolved defects |
| Rental | Transport, time limit, consumables and permitted use |
| Contractor | Written scope, access, disposal and restoration |
The stump-job example totals hypothetical rental, transport, consumables and personal protective equipment separately. Comparing an all-in rental total with a contractor’s matching scope is more useful than comparing a daily rental headline alone.
A $180 rental plus $60 transport, $25 consumables and $40 required equipment totals $305. Against a hypothetical $350 service quote for the same scope, the difference is $45. The figures are a worked comparison, not local offers.
Select the task before the model
Use equipment selection for a mower, saw, generator, washer or another task. Check access, material and actual output requirements. The equipment comparison matrix separates the factors a specification can establish from those needing a local quote or measured test.
A dealer asking price describes one offered package at a stated time. A private listing marked sold does not reveal the achieved sale price. Keep those source limits with any price used in your decision.
Before purchasing used equipment, record model and serial, service condition and recall applicability. An unverified service history belongs in the budget as uncertainty, not a fabricated remaining-life number.

Buying outdoor power equipment
Every other cluster assumes you already own the machine. This one is for the question before that: which machine to own at all. The comparison section identifies differences between equipment classes: Compare answers what separates two classes of machine against a published standard, which is the same answer for everyone; the guide answers which side of that classification your own driveway, yard, load list and budget put you on, which is not.
Twelve pages, each built around a real, measured question people ask: how many watts, what PSI, what clearing width, which line diameter, what CFM, gas or battery for this specific yard, whether an old machine is worth fixing, how a chainsaw or tiller is sized, whether a stump job is a rental or a professional’s, and whether a robotic mower even fits the yard.
Start from your own property
Which machine to buy depends on your driveway, your yard, your load list and your budget, so every guide below starts with a question about your property rather than a spec. To see what separates two classes of machine, such as a two-stage snow thrower from a single-stage one or a riding mower from a zero-turn, read Compare equipment types. Where a guide gives a price or size range, it is a class-level band meant to get you into the right neighborhood before the calculators or a machine's own rating plate finish the job.

Generator load sizing and connection choices
The load-list method that replaces a spec sheet: what to add up, which motor decides the starting-watt number, and how much headroom to leave: worked without needing a single manufacturer figure.

How to size a pressure washer
Which PSI-and-GPM band matches a car, a deck, a driveway or years of caked concrete, and the point at which "electric" stops being the plain answer.

How to size a snow blower
Choose stage, clearing width and intake height around the driveway surface and usual snow density.

How to choose a string trimmer
Line diameter and head type sized to what you are cutting, when a brushcutter blade is the plain upgrade, and where gas still beats battery on this specific tool.

How to size a leaf blower
Handheld, backpack or wheeled, matched to lot size and what is being moved. Wet leaf mat is a different job from dry leaves on a driveway, and CFM alone will not tell you which you have.

Gas vs. battery, for your yard specifically
Compare charging access, session length, quiet hours and the battery tools you already own.

Repair or replace old equipment
The three numbers that make this decision repair cost against replacement cost, the machine’s age against its class’s typical service life, and parts availability, instead of a gut feeling.

How to size a chainsaw
Why displacement against the work, not bar length, decides the purchase, and why the chain, not the saw, is what you keep buying for the life of the machine.

How to choose a tiller
Which of three different layouts your ground calls for, and when a wood chipper on the same shopping list is a separate purchase entirely.

How to size a wood chipper

Stump grinder or earth auger: rental or professional?
Why this is usually a rental-versus-professional decision rather than a purchase, and why what is buried underground decides it, not horsepower.

Is a robotic mower right for your yard?
Why the boundary system, not the blade, decides fit: perimeter wire against GPS by yard complexity and sky visibility, plus the schedule commitment either one requires.
The order to do this in
First, work out which kind of question you have. A generator or pressure washer purchase is a calculation.
The answer exists before you visit a store, and the page for each turns your own numbers into it. A snow blower, trimmer or blower purchase is a measurement against your own property.
Compare the workload and full ownership cost before choosing a power source or replacing a machine.
Second, do the calculation or the measurement before you compare brands. Getting the class and the size right eliminates most of the market and turns brand comparison into a much smaller decision, which is the same order the Compare cluster recommends for classification generally.
Third, check the class page for what the class needs in service before you buy, not after: the equipment cluster covers maintenance and ownership cost by class, and it is worth ten minutes before a purchase you will own for a decade.
Buying outdoor power equipment: questions
Do any of these buying guides recommend a specific brand or model?
No. Every page works from a class-level band or a calculation method, the same no-invented-specification rule that governs the rest of the site: see how we source and verify. Where a number is useful, it is a range consistent with the standards already cited, meant to get you into the right neighborhood before a calculator or a rating plate finishes the job.
Should I size my purchase for the biggest job I might ever do, or my typical job?
Typical, with modest headroom, not the rare, largest job. Sizing for an occasional worst case is how a pressure washer ends up stripping a deck it uses twice a year, or a generator sits underused at a fraction of its rated load every time it runs. Size bands follow the recurring job’s load, and notes separately where genuine headroom is worth the extra cost.
Is this buying cluster useful for someone replacing an existing machine, or only a first-time buyer?
Both: the repair-or-replace page specifically addresses the replacement decision for an existing machine, and once replacement is the answer, the same sizing pages apply whether it's someone's first generator or their third.
Does the buying cluster ever state a machine class isn't worth owning at all?
Yes, in specific cases: the snow blower page notes that in regions with only occasional light snow, a shovel or single-stage electric machine remains more plain than an underused two-stage machine, and the stump grinder page frames ownership itself as rarely justified for a homeowner's occasional need.
