A John Deere 647 tiller typically costs about $1,000-$2,800 used, with a serviceable average near $1,800; restored units or packages with hard-to-find drive parts can cost more. Price depends on condition, included drive components, local availability, and whether the tiller matches the buyer’s tractor and hitch.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Used 647 tiller | $1,000 | $1,800 | $2,800 | Working condition; local pickup assumed |
| Refurbished or tested unit | $2,000 | $3,000 | $4,000 | Higher price for documented work and parts |
| Inspection and minor service | $100 | $300 | $700 | Parts and labor vary with wear |
| Transport or delivery | $50 | $200 | $500 | Depends on distance and loading |
Assumptions: U.S. used-equipment market, attachment only, ordinary wear, and no major gearbox or driveline failure. John Deere 647 tillers are discontinued, so new-old-stock pricing is uncommon and may exceed these ranges.
What a used 647 tiller usually sells for
Most buyers should budget $1,000-$2,800 for a complete used unit, with roughly $1,800 representing a reasonable target for a working attachment with visible wear but no known major defects. A low asking price may indicate missing drive parts, damaged tines, or a tiller that has not been tested under load. A clean, serviced unit with proof of operation may command $2,500-$3,500 or more in a thin local market.
The 647 is an older Deere attachment, not a standard current-production tiller with a reliable new retail price. Listings can be sparse, and seller descriptions may not establish compatibility. Before agreeing on a price, confirm the exact model and what is included, especially the hitch or mounting pieces and driveline components required for the intended tractor.
How gearbox, tines, and labor shape the quote
Repair estimates depend on whether wear is limited to replaceable parts or reaches the gearbox and drive system. These are planning ranges, not a Deere dealer quote; older parts availability can change the final bill.
| Cost component | Typical range | What it covers | Pricing note |
|---|---|---|---|
| Tines and hardware | $100-$350 | Replacement blades, bolts, and minor fitting | Set condition and parts source matter |
| Gearbox or seals | $200-$900 | Leak repair or limited internal service | Major damage can exceed range |
| Driveline parts | $100-$500 | Shield, shaft, coupler, or related repairs | Missing assemblies may be difficult to source |
| Shop labor | $75-$125 per hour | Inspection, setup, and repair work | Commonly 2-6 hours for small jobs |
| Pickup or delivery | $50-$500 | Local hauling or longer-distance transport | Trailer and loading access affect price |
For example, 3 hours of shop work at $75-$125 per hour adds $225-$375 before parts.
Which 647 condition details change the price most
Rotating the tiller by hand with the machine safely disconnected can reveal rough bearings or binding, but it does not replace a running test. Gearbox noise, shaft damage, and missing model-specific connections can erase the savings on a low-priced listing. Inspect for oil leaks, cracked welds, bent tine flanges, uneven tine wear, and excessive movement at bearings. Ask whether the seller has run it recently in soil.
Two numeric checks help frame the quote. A set with several missing or badly worn tines can add roughly $100-$350 in parts, while a gearbox that needs substantial rebuilding may add $500-$1,200 or more, depending on damage and parts availability. A complete attachment that needs only cleaning and lubrication may need less than two hours of service; extensive disassembly can take 4-8 labor hours.
Compatibility is another price driver. Verify the 647’s mounting arrangement, driveline, and tractor requirements against the exact tractor model and serial range before purchase. A $1,000 tiller that needs a scarce adapter or shaft may cost more in total than a tested $2,000 package that includes the correct components.
How regional availability affects 647 tiller listings
As a discontinued attachment, the 647 does not have a uniform national market. Areas with many Deere garden tractors and established equipment dealers may have more listings and prices around the middle of the range. Rural areas with few comparable machines can have fewer options and asking prices 10%-25% higher, especially when a complete unit is available nearby.
Transport can reverse that calculation. A $1,500 listing several states away may add $300-$700 for freight, loading, or a hired trailer, putting it close to a local $2,000 unit. Compare the delivered cost, not just the advertised price, and confirm that the seller can load the attachment safely.
Three realistic buying totals for a 647 attachment
Budget for the whole transaction, including inspection and transport. These examples assume the buyer purchases the attachment rather than a tractor-and-implement package.
| Example | Purchase and work | Estimated total | Conditions |
|---|---|---|---|
| Local project unit | $1,000-$1,300 purchase plus $300-$700 parts and service | $1,300-$2,000 | Some wear; buyer handles pickup |
| Ready-to-use local unit | $1,600-$2,200 purchase plus $100-$300 inspection | $1,700-$2,500 | Complete, tested, ordinary wear |
| Refurbished shipped unit | $2,500-$3,500 purchase plus $300-$700 delivery | $2,800-$4,200 | Documented service; distance increases cost |
When a replacement tiller costs less than repairs
Compare repair cost with the price of another complete 647, not just the cost of individual parts. If a seller’s unit needs a gearbox rebuild, driveline replacement, and tine work, a repair estimate can reach $800-$1,500 before transport. At that point, a tested attachment near $2,000 may be the more predictable purchase, provided it fits the tractor.
A different used tiller may appear cheaper, but attachments are not interchangeable by appearance alone. Confirm hitch geometry, power requirements, shaft connections, and operating specifications. A substitute that requires custom fabrication or unavailable drive parts can create added labor and reduce resale value.
How to negotiate a lower 647 tiller price
Ask for a cold-start or operating demonstration, close-up photos of the gearbox and tines, and a list of included hardware before traveling. Use specific defects to negotiate: a missing shield, leaking seal, or worn tine set can support a parts-based offer. Set a maximum delivered price after estimating known repairs and compatibility hardware.
Local pickup and flexible timing can reduce freight charges, while bundling the tiller with compatible equipment may lower the seller’s per-item price. Avoid paying a premium for cosmetic repainting without service records. If a listing has been available for weeks, a firm offer tied to pickup date and payment method may be more effective than an unsupported low bid.
Questions to settle before paying for a Deere 647
Ask whether the price includes every required mounting and drive component, whether the gearbox holds oil, and whether the tines turn smoothly without unusual noise. Request the model identification and verify fit with the tractor documentation or a knowledgeable Deere parts source. A seller’s statement that it “fits most tractors” is not enough to establish a safe match.
Also clarify whether the buyer or seller handles loading, whether the attachment can be inspected before payment, and whether any parts are being sold separately. Because the 647 is an older model, a refundable deposit or return agreement may not be available; an in-person inspection and written list of included parts help limit costly surprises.
