Lawnmowers, Generators, and What It Actually Pays
If you can keep a small engine running, there’s real money in it – and unlike a lot of the trade work I cover on this site, this one doesn’t require a license in most places, and the worst-case failure is “it still doesn’t start,” not “the house floods.” Here’s what actually pays, what it takes to get started, and the honest seasonal reality nobody mentions upfront.
What actually needs fixing
Lawnmowers are the bread and butter – carb cleaning, blade sharpening, spark plug and air filter swaps, pull-cord replacement. Generators are the second-biggest category, and demand for these spikes hard right before storm season since half the units sitting in garages haven’t been started since last year and won’t turn over when someone actually needs them. Chainsaws, pressure washers, snowblowers, and string trimmers round out the rest. None of this requires specialty diagnostic equipment – it’s mostly carburetors, ignition systems, and basic mechanical wear, the same fundamentals across most small gas engines regardless of what they’re bolted to.
What you actually need to get started
A basic small engine tool set – you likely already have most of it if you’ve done any mechanical work: socket set, spark plug gauge, carb cleaner, a way to test compression, basic hand tools. No specialty diagnostic scanner required, unlike automotive work. A trailer or truck bed helps if you’re picking up bigger equipment like riding mowers or larger generators, but plenty of this work – carb cleaning, blade sharpening, tune-ups – can happen at the customer’s location with a tool bag.
The legal and business side – genuinely simpler than most trades
Here’s the good news: most states don’t require a specific trade license for small engine repair, unlike automotive work or electrical. What you do need is a general business license from your city or county – typically $50-400 depending on where you are – and if you’re selling parts alongside labor, a seller’s permit for sales tax.
The part that actually matters and gets skipped: EPA rules on disposing of used oil and old fuel. You can’t just pour it out or toss it in the regular trash – most areas have specific used-oil collection requirements, and getting caught disposing of it wrong can mean real fines. Have a plan for this before your first job, not after.
Two specific exceptions worth knowing: if you branch into motorcycle repair specifically, some states do require a separate license for that – check before you take on bikes. And if you ever work on equipment with an air conditioning component (rare in pure small-engine work, but it exists on some commercial-grade equipment), handling refrigerant requires EPA Section 609 certification. Neither applies to standard mower/generator/chainsaw work, but worth knowing the lines.
What it pays
Simple tune-ups and carb cleanings typically run $50-100 depending on your area. Generator servicing, especially the pre-storm-season rush, often commands more – $75-150 isn’t unusual when someone’s genuinely worried their backup power won’t work. More involved repairs – engine rebuilds, major carburetor work – can run $150-300+ depending on the equipment and what’s actually wrong with it.
The honest seasonal reality
This isn’t steady, year-round income, and I’d rather tell you that upfront than have you find out the hard way. Spring brings the mower rush as everyone tries to get their equipment running for the season. Late summer into fall brings the generator rush, as people realize storm season’s coming and their unit hasn’t run since last year. Winter is genuinely slow for most of this work, snowblowers being the one exception that flips the pattern. If you’re planning this as a side hustle, think of it as strong seasonal income you stack with something else, not a flat year-round stream.
Finding your first clients
Same playbook as the rest of the mechanic cluster on this site: word of mouth beats any platform for your first jobs. Post in local Facebook groups and on Nextdoor specifically mentioning small engine repair – most people have no idea who to call for this and end up either doing it themselves badly or just buying new equipment they didn’t need to replace. If you want built-in job flow while you build a reputation, TaskRabbit sees real demand for this kind of hands-on repair work, same as it does for handyman jobs.

If cars are more your speed than small engines, starting a mobile mechanic side hustle covers that specific path, and how to make money on YourMechanic covers one platform worth knowing about if you go that route.
Frequently Asked Questions
In most states, no specific trade license is required for general small engine repair like mowers, generators, and chainsaws. You’ll typically need a general business license from your city or county, and a seller’s permit if you’re selling parts. Motorcycle repair specifically requires licensing in some states.
You can’t dispose of used oil or fuel in regular trash or by pouring it out. Most areas have specific used-oil collection programs through auto parts stores, recycling centers, or municipal collection sites. Check your local EPA and municipal guidelines before your first job.
No, it’s genuinely seasonal. Spring brings a mower tune-up rush, late summer into fall brings a generator servicing rush ahead of storm season, and winter is typically slow outside of snowblower work. It works best stacked alongside another income source rather than relied on as steady year-round income.
Simple tune-ups and carb cleanings typically run $50-100. Generator servicing, especially before storm season, often runs $75-150. More involved repairs like engine rebuilds can run $150-300 or more depending on the equipment and the extent of the work.
