An Ariens ST350 snowblower typically costs about $100-$350 used, with a fair-condition machine averaging around $225; restored or unusually clean examples may reach $400-$600. The ST350 is an older, discontinued snowblower, so condition, local demand, parts availability, and the cost of getting it running matter more than a current-model list price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Used Ariens ST350, running | $100 | $225 | $350 | Typical private-sale range; price varies by condition and location. |
| Clean or serviced ST350 | $250 | $400 | $600 | Higher asking prices need to be supported by recent service and working parts. |
| Nonrunning project machine | $25 | $75 | $150 | Useful mainly for parts or repair by an owner with mechanical skills. |
| Basic tune-up or repair | $75 | $175 | $400+ | Shop labor and replacement parts can exceed the purchase price. |
| New comparable single-stage snowblower | $600 | $800 | $1,100 | Current models vary by brand, engine, width, and features. |
What a used Ariens ST350 usually sells for
Most buyers should budget $100-$350 for a running ST350 in ordinary used condition. A machine that starts easily, throws snow consistently, and has intact controls and housing is more valuable than one that merely turns over. Prices above $400 are easier to justify when the seller can demonstrate operation and document recent work.
The original ST350 is not a current new-product model, so a listing advertised as “new” may mean old stock, a rebuilt unit, or a machine that has not been used recently. Confirm what the seller means. For an old stored snowblower, age-related fuel-system, belt, rubber, and corrosion problems may remain even if the machine looks clean.
Assumptions: private-party sale, standard residential machine, normal access to inspect, and U.S. dollars before tax or transport.
Used-equipment prices are local rather than fixed national prices. In snow-heavy areas, working machines can sell quickly before winter. In a mild-weather region, a seller may accept less, but finding a knowledgeable repair shop or compatible parts can be harder. A buyer should compare the asking price with the cost of repairs, not just with another listing.
How engine, auger, and shop labor shape the bill
A used-machine price can be only part of the expense. For an ST350, the engine’s starting and running condition, the single-stage auger system, drive components, controls, and safety equipment are central to the inspection. A dealer or small-engine shop may also charge a diagnostic or minimum service fee before identifying the problem.
| Quote item | Typical price | What it may cover | Cost note |
|---|---|---|---|
| Inspection or diagnostic | $40-$100 | Compression, fuel, spark, controls, and operating check | Some shops apply the fee toward approved repairs. |
| Basic tune-up parts | $20-$75 | Spark plug, fuel filter or line, and basic service items | Exact parts depend on engine identification. |
| Carburetor cleaning or replacement | $75-$250 | Cleaning, adjustment, or replacement part | Stale fuel and storage are common reasons for work. |
| Belt or friction-drive work | $50-$200 | Part plus installation, where applicable | Confirm the exact model and component before ordering. |
| Auger or housing repair | $100-$350+ | Wear-part replacement or more involved mechanical work | Severe damage can make repair uneconomical. |
| Pickup or delivery | $25-$100 | Local transport to a repair shop | Distance and loading needs affect the fee. |
Shop labor commonly runs about $75-$125 per hour, with regional and seasonal differences. A simple adjustment may take under an hour, while diagnosis followed by carburetor, belt, or auger work can require several hours and parts.
Parts listings can be confusing for a discontinued machine. Buyers should record the model and serial information and verify part fit with a parts supplier or qualified shop before paying. A similar-looking component may not fit an older production version, and an unavailable part can turn a modest repair into a search for used components or a donor machine.
Which ST350 condition details move the price most
The biggest price difference is usually between a demonstrably working snowblower and a project machine. Ask for a cold start, then watch it run long enough to check for stalling, heavy smoke, unusual vibration, and failure to engage the auger. A warm engine at pickup can hide hard-starting problems.
For an untested ST350, price it as a repair project rather than as a working machine. A seller’s statement that it “ran last year” is not equivalent to a current test. If a buyer cannot test it, a $25-$150 offer may be more reasonable, depending on completeness, visible damage, and the value of recoverable parts.
- Engine condition: Easy starting and steady running support the upper part of the used range. Fuel leaks, no-start symptoms, or serious smoke warrant a repair allowance of $75-$250 or more.
- Auger operation: A properly engaging auger is essential. Bent or damaged parts, missing hardware, or a worn housing can add $100-$350 or push the machine beyond economical repair.
- Storage and corrosion: Rust on exposed fasteners is different from deep corrosion or cracks in structural areas. Long storage with fuel in the tank can increase carburetor and fuel-line work.
- Completeness: Missing controls, guards, or other necessary parts reduce value. Do not assume replacements are easy to source for a discontinued model.
- Service evidence: Receipts for recent engine or wear-part work can support a higher price, but only if the machine operates correctly during inspection.
Width and engine details should be verified from the machine’s identification plate and manual rather than inferred from a listing title. Buyers should also check whether the seller is describing an ST350 itself or another Ariens model with a similar name. An incorrect model identification can lead to the wrong parts, dimensions, and value comparison.
Why ST350 prices vary between snowy and mild regions
Regional demand can shift used asking prices by roughly 10%-30% compared with a typical local market. In parts of the Northeast, Upper Midwest, and northern Mountain states, a running snowblower may command a premium before the first major snowfall. In milder Southern or coastal markets, lower demand can bring prices down, although transport and repair access may offset the saving.
Season changes bargaining power as much as the ZIP code does. Listings often become more competitive in late fall and during early storms, when buyers need equipment immediately. In spring or summer, sellers may be more willing to negotiate because the next use is months away. These are tendencies, not guaranteed discounts: a clean, serviced machine can still sell quickly out of season.
Urban areas can have more listings and repair shops but higher labor and delivery charges. Rural buyers may find a lower asking price yet face longer pickup distances or fewer technicians familiar with older machines. Add $25-$100 for local delivery when a seller or shop provides it, and account for fuel, trailer rental, or a second person if pickup requires the buyer’s own transport.
Weather-related urgency can also affect repairs. A shop may have limited turnaround during the first snow events, while a routine pre-season appointment may be easier to schedule. If immediate availability matters, compare the total cost of a working local machine with a cheaper nonrunning one plus transport and shop time.
Three realistic purchase-and-repair totals
The examples below show how a low asking price can produce a higher final bill. They are estimates for typical private-party purchases and independent-shop work, not guaranteed quotes. Parts, regional rates, and the actual condition of a particular ST350 can change the totals substantially.
| Scenario | Purchase | Work and extras | Estimated total |
|---|---|---|---|
| Running machine, buyer pickup | $225 | $0-$50 for basic service items and fuel | $225-$275 |
| Starts poorly, needs shop attention | $100 | 1.5-2 hours at $75-$125 per hour, plus $25-$75 parts | $238-$425 |
| Nonrunning project with transport | $75 | $40-$100 pickup, diagnostic, and likely $100-$250 initial repair | $215-$425 |
A $100 ST350 can cost more than a $250 tested machine after diagnosis and repair. The third example is especially uncertain: if the engine or auger has major damage, the estimate can rise above $425 without making the snowblower dependable. A firm repair quote after inspection is more useful than pricing a project from the seller’s description alone.
For comparison, a new single-stage model priced around $600-$1,100 generally offers current parts support and a warranty, though it costs substantially more upfront. A used ST350 may make financial sense when it is complete, working, and priced below the cost of likely repairs. The comparison should include expected maintenance and the buyer’s ability to handle basic work.
How long an ST350 inspection or repair can take
A buyer can complete a basic driveway inspection in about 15-30 minutes, provided the seller allows a cold start and operating test. A shop diagnosis may take 30-60 minutes of billed labor, but turnaround time on the calendar can be several days or longer during peak winter demand. Some repair shops use a minimum charge even when the work itself is brief.
Schedule an inspection before peak snow season when possible. A pre-season visit can leave time to find parts or choose another machine. During a storm, shops may prioritize urgent jobs, and a waiting customer may have little leverage to approve alternatives or compare repair prices.
For a rough labor budget, use the shop’s stated hourly rate multiplied by estimated work time, then add parts and any diagnosis fee. For instance, two hours at $90 per hour plus $45 in parts is $225 before tax or transport. Ask whether the shop will stop and seek approval if the repair estimate exceeds a stated limit.
Should a buyer repair an ST350 or replace it?
Repair is often easier to justify when the machine is already owned, structurally sound, and needs a limited service such as a tune-up or one routine component. For a purchase, an ST350 priced at $150 with a likely $100 repair may still be reasonable if it passes testing and the final cost remains comfortably below a comparable new machine.
Compare the repair total with the price and support of a current replacement. If an ST350 needs $300-$500 in uncertain work, has serious corrosion, or lacks hard-to-find components, a new $600-$1,100 single-stage snowblower may be the lower-risk choice. A used current-generation model can also provide a middle ground, but it needs the same inspection for wear, starting, and service history.
DIY repair can reduce labor expense, but it is not automatically the cheapest route. A carburetor clean or spark-plug change may suit an experienced owner; work involving uncertain engine damage, auger assembly, or safety controls can require tools and model-specific knowledge. Incorrect repairs can damage parts or create an unsafe machine, so a buyer should include the value of time and the cost of getting the work checked.
Ways to keep an Ariens ST350 purchase within budget
Set a maximum total before making an offer. For a running machine, subtract anticipated service, transport, and tax from the budget to determine the purchase ceiling. For a nonrunner, base the offer on the value of parts and the worst plausible repair, not on the seller’s hoped-for diagnosis.
- Test before paying: Ask to see a cold start, stable operation, and auger engagement. If testing is not possible, negotiate as an unverified project.
- Check model identity: Photograph the model and serial plate and verify parts availability before promising a repair budget.
- Compare complete quotes: Ask shops to separate diagnostic fees, labor hours, parts, pickup, and tax. A low hourly rate may not mean a lower total.
- Choose timing carefully: Shop in spring or summer when urgency is low, while still checking that the machine has not been stored with old fuel or left exposed to weather.
- Avoid unnecessary upgrades: Prioritize safe operation and essential repairs; cosmetic work rarely raises the value enough to recover its cost.
- Consider local pickup: A $25-$100 delivery charge can erase savings on a low-priced machine. Confirm loading help and transport needs in advance.
The best-value ST350 is usually a complete, tested machine with a clear service history, not the lowest-priced listing. A buyer should compare its purchase price plus likely first-season expenses against a current replacement and decide based on the final total, repair access, and confidence in the machine’s condition.
