John Deere 318 Specs, Reviews & Used Price Canada (2026)

The John Deere 318 is, by broad enthusiast consensus, the greatest garden tractor ever built — and unusually for such titles, the machine backs it up with engineering. Built in Horicon, Wisconsin from 1983 to 1992, it put full hydrostatic power steering, two independent hydraulic circuits, a shaft-driven hydrostatic transmission, and a 26-inch turning radius into an 18-horsepower garden tractor — equipment its rivals didn’t offer and most modern lawn tractors still don’t. Deere sold them in enormous numbers (Horicon’s one-millionth lawn and garden tractor, built in May 1984, was a 318), and a devoted restoration-and-parts economy keeps thousands mowing, blowing snow, and tilling Canadian properties three decades after the last one left the line.

One naming note: John Deere’s 318D, 318E, and 318G skid steers share the number and appear in the same Canadian search results — the 318G is reviewed separately on Aglist [ADD LINK when slug verified]. This page covers the 1983–92 garden tractor. Status disclosure: the 318 is long discontinued (the 300-series gave way to the 325/345 family), and this page is written for the 2026 used buyer — who is really making two linked decisions: which 318, and what to do about the Onan.

Aglist quick take: The 318 is the small-acreage Swiss Army knife — the hydraulics run the deck, angle the blade, and lift the blower from the seat, and the attachment ecosystem (decks, blowers, blades, tillers, even the Model 44 loader) is the real asset you’re buying. The honest framing: the Onan twin is smooth, torquey, and typically tired by 1,500–2,000 hard hours — with parts getting pricier every year — which makes “rebuild, repower, or buy one already done” the central 318 ownership question. The market has answered pragmatically: Vanguard- and Honda-repowered units sell openly in Canada, and only collectors pay extra for a numbers-original Onan.

Quick Verdict — Who the 318 Is For

Buy it if: you want one compact machine that genuinely mows (38/46/50-in. hydraulic-lift decks), moves snow (46-in. single or 47-in. dual-stage blowers, 54-in. hydraulic-angle blade), tills, and even loads — with power steering and hydraulics no modern lawn tractor at CAD $4,000 offers — at roughly CAD $2,000–$5,500 depending on condition and attachments. A healthy P218G (or honest repower) with the 50-in. deck and a blower is the classic Canadian package.

Skip it if: you only mow — a modern zero-turn cuts faster for the money [ADD LINK to JD zero-turn guide when slug verified] — or you want new-machine simplicity, where today’s equivalent of the 318 buyer’s mindset is a sub-compact like the John Deere 1025R with a mid-mount deck.

Why the hydraulics matter. On a 318 you raise the deck, lift the blower, and angle the 54-in. blade from the seat — with real hydraulic cylinders, not cables and springs. Combined with power steering and the 26-in. turning radius, it’s why owners describe the 318 as a shrunken utility tractor rather than a big lawn mower, and why the platform still commands real money.

Owner Reviews & Ratings on Aglist

Deere’s brochures are forty years old; the ownership record has compounded through every Canadian season since. As owners share their experience on Aglist, the rating system tracks:

• Engine status — original Onan health, rebuild history, or repower details (what engine, what kit)
• Hydraulics and steering — circuit health, cylinder seepage, steering feel
• Attachment experience — decks, blowers, blade, tiller, loader in real use
• Parts and service — Onan and Deere sourcing in your region
• Value for money — purchase-plus-upkeep versus a modern machine

If you own or run a 318 in Canada, please leave a star rating and a short note below — engine era and repower details are exactly what future buyers most need.

John Deere 318 vs the Alternatives

The 300-series family frames the choice — same platform, four philosophies.

Spec	John Deere 316	John Deere 318	John Deere 322 / 332
Engine	16 HP Onan twin	18 HP Onan twin	18 HP Yanmar 3-cyl (322 gas / 332 diesel)
Power steering	No	Yes	Yes
Hydraulics	Varies	Dual circuit	Dual circuit
Character	Budget entry	The benchmark	The smooth (and thirftier) rarities
Typical Canadian price	Below 318	CAD $2,000–$5,500+	Premium for diesels

Where the 318 wins: the complete package at the sane price. The 316 saves money but steering it after a 318 feels like a punishment; the Yanmar-powered 322/330/332 solve the Onan question elegantly but trade at collector premiums and thinner parts paths for their engines. The 318 is the volume model — deepest parts supply, biggest attachment pool, easiest resale.

Where the math flips: if the property has outgrown garden-tractor scale, a used sub-compact — today’s John Deere 1025R class — brings diesel power, a real loader, and a warranty path for several times the money. If the job is purely mowing, modern zero-turns cut faster per dollar [ADD LINK to JD zero-turn guide]. Browse all tractors on Aglist for the full landscape.

Real-World Performance

The Onan question — rebuild, repower, or buy it done

The air-cooled Onan twin is smooth and torquey, and its life cycle is well documented by the ownership community: with religious oil changes it runs happily toward 1,500–2,000 hours, then announces its age with oil consumption, smoke, and the distinctive “tired Onan” smell as rings and guides wear — hard-worked year-round units sometimes sooner. Onan has been out of production for decades; parts remain available but climb in price yearly. The three honest paths: a professional rebuild (specialist shops exist and ship crates; roughly a $2,000-class job), a bolt-on repower kit — Briggs Vanguard and Honda twins are the community favourites, sold as complete conversions — or buying a unit where someone else already made the choice. The Canadian market has normalized all three: Vanguard- and Honda-powered 318s sell openly, priced on function, while numbers-original Onans matter mainly to collectors. Whatever the badge on the flywheel shroud, buy compression numbers and an oil-pressure story, not paint.

Drivetrain, steering & the daily experience

The shaft-driven hydrostatic (no belts to slip or fling) with its dash-mounted speed control, the power steering, and the 26-inch turning radius make the 318 genuinely effortless — the reason original owners kept them for decades and their grandchildren hunt them now. The rubber-isolated engine mounts and the reserve fuel tank (15–30 bonus minutes when the main runs dry) are the kind of details that built the cult.

Attachments — the real asset

A bare 318 is half the story. The hydraulic-lift decks (38/46/50-in.), the Model 49 single-stage and Model 47 dual-stage blowers, the 54-in. blade with hydraulic angling, hydraulic-drive rear tillers, and the Model 44 loader turn one machine into a four-season fleet — and in Canada the attachments hold value independently: rear tillers trade around $850, dual-stage blowers near $1,400, and rebuilt deck-spindle sets at $300 in the current classifieds. A tractor with the blower, blade, weights, and chains is worth genuinely more than the sum’s appearance — and loader-equipped units with forks and multiple buckets surface as miniature workhorses.

Canadian Winters

This is the 318’s second season and half its Canadian reputation: blower or blade up front, wheel weights and chains on the back, and — very commonly — a soft cab (Cozy Cab and similar) that turns January driveways into a shirtsleeve job. The auxiliary hydraulic circuit lifting the blower and the electric chute options beat every cable-lift competitor of the era. Standard cold rules apply: fresh battery, stabilized fuel, and the air-cooled twin actually likes the cold once running. Our prairie winter equipment operation guide covers the broader setup habits.

Common Problems & Reliability Notes

Transparency note: patterns reported across a huge, decades-old ownership base, not confirmed defects on any given unit — and the parts being actively sold in Canadian classifieds are themselves the honest map of what wears.

Onan aging and ignition. Beyond the ring-and-guide life cycle above, ignition components (modules, coils) are the classic no-start culprits on original engines — known, replaceable, and worth testing hot as well as cold.

Carburetion on stored units. Fixed-jet carbs gum up in storage; surging and hard starting after winter usually means cleaning, not catastrophe.

PTO clutch wear. New replacement clutches for the 316–332 family sell steadily for a reason — test engagement under load and budget accordingly.

Deck spindles and shells. The rebuilt-spindle market exists because spindles wear; check for wobble and listen for bearings, and inspect shell rust at the usual seams.

Hydro linkage and seepage. Sloppy speed-control linkage and minor cylinder weep are age items; a hydro that whines, jerks, or won’t hold speed is a bigger conversation — hence the standing wanted-ads for good transaxles.

Front-end wear. Spindle bushings and tie-rod ends on a power-steering machine wear quietly — lift the front and check play.

The platform endures. Deere still lists many parts, the Onan aftermarket persists, repower kits are an industry, and a wrecking-and-rebuilding ecosystem (including Canadian shops) keeps 318s alive indefinitely — the definition of a supported classic.

Used Price Range in Canada (2026)

The 318 trades constantly on Kijiji, Facebook, and auction platforms across Canada, priced by engine status and attachments more than by year. Indicative ranges:

• Projects and non-runners: roughly CAD $800–$1,800 — tired Onans, missing decks; still liquid thanks to the parts demand
• Honest runners with a deck: roughly CAD $2,000–$3,500 — the heart of the market, original Onan or straightforward repower
• Four-season packages (blower or blade, weights, chains, often a soft cab): roughly CAD $3,500–$5,500
• Loaded and exceptional units (Model 44 loader outfits, fresh professional rebuilds/repowers, 3-point + rear PTO, restorations): CAD $5,500–$8,000+

Value movers: engine status with evidence (rebuild receipts or repower kit details), attachment count, hydraulics health, and completeness of the winter kit. Attachments alone hold value — which also means incomplete tractors price accordingly.

Best Use Cases in Canadian Conditions

Acreage and large-lot four-season duty (ON / Prairie towns / everywhere). Mow all summer, blow snow all winter, till in spring — one machine, one shed bay. Snow-first buyers. Blade or blower with hydraulic lift, chains, weights, soft cab: the classic Canadian driveway rig. Garden and hobby-farm ground work. Hydraulic rear tiller plus Cat 0 hitch on the optioned units. Light loader chores. The Model 44 outfits handle mulch, gravel, and firewood at garden scale. Collecting and restoration. The most supported classic in the category. Not ideal for: mowing-only buyers (zero-turns win), heavy loader ambitions (that’s sub-compact territory), or anyone unwilling to engage with the Onan question.

Maintenance & Service

• Every use: oil level (air-cooled twins consume some by design when aging), tire pressure, debris off the cooling fins — fin hygiene is Onan life insurance
• Per the manual: engine oil and filter religiously (the single biggest Onan-life factor), air cleaner and pre-cleaner, fuel filter, plugs and points/module as equipped
• Hydraulics: keep the reservoir topped with the correct fluid, exercise both circuits, fix weeps before they’re leaks
• Drivetrain: hydro fluid per schedule; speed-control linkage snug; PTO clutch air gap checked
• Deck and implements: spindle grease where fitted, blade balance, shell rust treated early; blower gearbox oil and shear bolts stocked
• Storage: fuel stabilized or drained, battery tended — most 318 “problems” are storage problems

Parts flow through Deere dealers, the Onan aftermarket, repower specialists, and an active Canadian used-parts scene — few 40-year-old machines are easier to keep alive.

Where to Find a Used John Deere 318 in Canada

Kijiji and Facebook Marketplace are the volume channels, with auction platforms adding estate and municipal units — filter out the 318-series skid steers that share the search. Inspection priorities, in order: settle the engine question first — original Onan (compression both cylinders, oil pressure, smoke, ignition hot and cold) or repower (what kit, installed how, receipts); run both hydraulic circuits and the steering through full travel, watching for weep and listening to the pump; drive the hydro through its full range both directions, cold and warm; engage the PTO under load; spin every deck spindle and rock the blades; lift the front end for spindle play; and inventory the attachments against the price, because they carry the value. A straight tractor with a documented engine answer, healthy hydraulics, and the winter kit is the buy-once 318 — and the reason these outlive the machines bought to replace them.

John Deere 318 FAQ

How much horsepower does a John Deere 318 have? 18 HP at 3,600 rpm from an air-cooled Onan twin — the B43G (43.3 cu in) through 1986, and the P218G (47.7 cu in) from 1987 to the end in 1992.

What years was the John Deere 318 made? 1983–1992 in Horicon, Wisconsin — and in May 1984, Horicon’s one-millionth lawn and garden tractor built was a 318.

Why is the John Deere 318 so popular? It brought full hydrostatic power steering, two hydraulic circuits, shaft-driven hydro, and a 26-inch turning radius to a garden tractor — utility-tractor engineering at residential scale, backed by an attachment ecosystem from 50-in. decks to a front loader.

How long does the Onan engine last, and what if it’s tired? Well-maintained Onans typically reach 1,500–2,000 hours before rings and guides announce retirement. The established paths: professional rebuild (~$2,000 class), a bolt-on Vanguard or Honda repower kit, or buying a unit already converted — all three are normal and openly traded in Canada.

Does a repowered 318 lose value? For working buyers, no — clean Vanguard/Honda conversions sell readily and remove the aging-Onan question. Numbers-original engines matter mainly to collectors and show restorations.

What attachments fit a John Deere 318? Hydraulic-lift decks at 38, 46, and 50 inches; the Model 49 single-stage and Model 47 dual-stage snowblowers; a 54-inch blade with hydraulic angling; hydraulic rear tillers; a vacuum collection system; and the Model 44 front loader — plus an optional Category 0 hitch and 2,000-rpm rear PTO.

Is this the same 318 as the John Deere skid steer? No — the 318D, 318E, and 318G are unrelated skid steer loaders that share the number and clutter the same searches. The 318G is reviewed separately on Aglist.

How much does a John Deere 318 cost in Canada? Roughly CAD $2,000–$3,500 for honest runners with a deck, $3,500–$5,500 for four-season packages with snow equipment, and $5,500–$8,000+ for loader outfits, fresh rebuilds/repowers, and restorations — with projects under $1,800, as of 2026.

Disclaimer

Specifications compiled from John Deere technical literature for the 300 Series and cross-checked reference sources; the 318 was built over ten model years with two engine generations (Onan B43G through 1986; P218G from 1987) and an extensive factory and field-installed options list, and a large share of surviving units carry rebuilt or replacement engines, so individual machines vary substantially from factory specification. The John Deere 318 is a discontinued model — availability is limited to the used market, and pricing reflects indicative Canadian ranges that vary by region, condition, engine status, and attachment complement. Reviews on Aglist are written by real users and moderated for spam — opinions are personal. Always confirm specifications, engine identity, and condition against the operator’s manual, serial-number information, and a thorough physical inspection — including compression testing and full hydraulic function checks — before committing to any specific machine.
