Inspection Progress:0 / 10 Items Checked
Red Flag Items = Walk away or negotiate $200+ discount
1. Engine & FluidsCRITICAL RED FLAG

Check Engine Oil Level & Color

Pull dipstick before starting. Oil should be golden to light brown. Milky white or gray oil means water/snow entered crankcase. Pitch black gritty oil means zero maintenance.

Estimated Fix Cost: Low ($10 DIY oil change) unless engine knocked
1. Engine & Fluids

Smell Gas Tank (Ethanol Varnish Check)

Remove fuel cap and sniff. If it smells like varnish or sour turpentine rather than fresh gasoline, old fuel sat in carburetor and jets will be clogged.

Estimated Fix Cost: $30 DIY carb clean or $85 shop ultrasonic rebuild
1. Engine & FluidsCRITICAL RED FLAG

Insist on a True Cold Start

Touch muffler before starting to ensure the seller did not warm it up prior to your arrival. Set choke, prime 3x, pull or push electric start. Should fire within 3 pulls or 5 seconds on electric start.

Estimated Fix Cost: $50–$150 (Ignition coil, spark plug, or carburetor rebuild)
2. Auger, Impeller & DriveCRITICAL RED FLAG

Inspect Auger Gearbox for Oil Leaks & Cracks

Crawl under front housing and inspect center cast iron/aluminum gearbox. Check for weeping gear lube or horizontal hairline cracks from hitting hidden rocks or curbs.

Estimated Fix Cost: RED FLAG: $250–$450 to replace gearbox. Dealbreaker!
2. Auger, Impeller & DriveCRITICAL RED FLAG

Verify Factory Shear Pins (NOT Hardware Store Grade 5 Bolts)

Examine pins connecting auger spiral blades to the drive shaft. If seller substituted hardened Grade 5 or 8 hardware bolts, the gearbox has lost its protection against catastrophic jams.

Estimated Fix Cost: $6 for 4 proper shear pins; inspect shaft carefully
2. Auger, Impeller & Drive

Check Impeller Bearing Play

With engine OFF and spark plug boot disconnected, reach into chute and wiggle the fan blades. There should be zero fore-and-aft wobble in the center bearing.

Estimated Fix Cost: $45 bearing replacement
3. Transmission & Traction

Test All Forward & Reverse Gears Under Load

Engage drive handle. Shift through every forward gear (1 through 6) and both reverse gears. Machine should immediately pull without hesitating, shuddering, or slipping.

Estimated Fix Cost: $25–$45 rubber friction disc ring replacement
4. Chute & Housing Rust

Operate Chute Rotation Crank & Pitch Cable

Turn chute 180 degrees left and right. Cables should not bind or have frayed wire strands. Plastic chutes should be checked for winter stress cracks.

Estimated Fix Cost: $20–$50 replacement cable
4. Chute & Housing Rust

Inspect Housing Scraper Bar & Skid Shoes

Check bottom scraper blade. If worn down completely into the housing steel, the bucket itself will be compromised. Skid shoes should have reversible wear remaining.

Estimated Fix Cost: $25 for new poly or steel shoes + scraper bar
3. Transmission & Traction

Examine Tire Sidewalls for Dry Rot & Rim Rust

Look between tread blocks for dry cracking. Check if tires hold pressure or if valve stems are cracked. Rusted-on wheel axles can make tire changes impossible.

Estimated Fix Cost: $40–$70 for replacement tire/wheel assemblies

Missouri Used Market Tip: Late August through early October is prime buying time on Missouri Facebook Marketplace. Ariens Classic/Deluxe units under 10 years old typically sell between $350–$650. If buying in January during a blizzard warning, expect to pay a $200+ panic premium.

Frequently Asked Questions

A cracked or stripped auger gearbox. Replacing the center cast iron or aluminum gearbox costs $250 to $450 in parts and labor—often more than the purchase price of the used machine. If the gearbox has oil leaks, cracked casing, or spins loosely without engaging the impeller, walk away immediately.
