A new John Deere Z900 Series zero-turn mower typically costs about $10,000-$21,000 before tax, while used machines can start near $4,000. The exact price depends on model, deck width, engine, dealer location, hours, condition, and included accessories.

What a new Z900 mower usually costs
Dealer pricing commonly falls around $10,000-$21,000 for a new Z900 Series machine. Entry models such as the Z920M tend toward the lower end; larger or more equipped models, including Z950R and Z970R configurations, can approach the upper end. A representative purchase budget is about $15,000 before sales tax.
Budget roughly $12,000-$18,000 for many standard new configurations. These are practical U.S. quote ranges, not fixed manufacturer prices; promotions, stock, and dealer charges change the transaction total. Deck width, suspension seat, engine package, and commercial-duty features can shift a quote by thousands of dollars.
Assumptions: New mower, standard commercial configuration, normal dealer availability, before sales tax and optional attachments.
How the mower, setup, and delivery shape the quote
A mower quote primarily reflects the machine itself. Setup, freight or delivery, attachments, and applicable tax can add to the out-the-door total. Ask the dealer to identify whether assembly and fluid checks are included, and whether delivery is priced separately.
| Quote item | Typical price | What changes the amount |
|---|---|---|
| Base mower | $10,000-$21,000 | Model, deck, engine, and package |
| Dealer setup | $0-$400 | Included preparation or charged labor |
| Delivery | $0-$400 | Distance and dealer policy |
| Mulching kit or bagger | $300-$1,500 | Attachment type and compatibility |
| Sales tax | About 0%-10% of taxable amount | State and local tax rules |
Compare the out-the-door total, not just the advertised mower price. For example, a $15,000 machine with $500 in setup and delivery and 7% tax on the taxable amount could total about $16,585.
Deck width and engine options change the price
Deck size is a major cost driver: Z900 configurations commonly use decks around 48-72 inches, depending on model. A 60- or 72-inch deck can cost more than a smaller deck, but may cover open acreage faster. Narrower equipment can be more practical where gates, trees, or landscaped beds restrict access.
Model and engine specifications also matter. Moving from a midrange Z920M or Z930M configuration to a higher-spec Z950 or Z970 can raise the purchase price by several thousand dollars. Suspension and seat upgrades can add roughly $500-$1,500, while a collection system may add several hundred dollars to more than $1,000.
Check the exact model suffix and deck measurement on each quote. Similar model names can carry different equipment, and a price comparison is meaningful only when engine, deck, seat, and included accessories match.
Is a used Z900 cheaper after inspection?
Used Z900 mowers often sell for about $4,000-$16,000. Older machines with substantial hours or cosmetic wear may sit near the lower end; late-model units with low hours and maintenance records can approach new-machine pricing. The advertised price alone does not reveal likely repair expense.
Before buying, check engine hours, service history, deck condition, spindle noise, hydrostatic drive response, tire wear, and signs of frame damage. A dealer inspection may cost about $100-$300. A worn deck belt or blade service may be modest, but hydrostatic or engine repairs can reach $1,000-$3,000 or more.
A used machine is a better value when its service records and mechanical condition support the discount. Compare its purchase price plus immediate repairs with a new mower’s warranty and expected service needs.
Regional dealer quotes vary with freight and inventory
Regional differences often come from freight, dealer competition, inventory, and seasonal demand rather than a single nationwide price schedule. A mower in a competitive metro market may be 3%-8% below a comparable rural quote; freight or limited stock can instead push a remote-area quote 5%-10% higher.
Prices may be more negotiable when dealers have several comparable units in stock. In spring, demand can limit discounting; late-season inventory changes may create more room, though selection can be smaller. Request quotes from at least two dealers and compare the same model and deck.
Use the same configuration and delivery terms when comparing regional offers. A lower advertised price may be offset by freight, setup fees, or accessories that another dealer includes.
Three Z900 purchase scenarios with realistic totals
A basic new configuration priced at $11,500, with $250 setup and no paid delivery, would total about $12,573 with 7% tax. A midrange mower at $15,000 plus $500 setup and delivery would reach about $16,585 at the same tax rate.
A higher-spec mower at $19,000 with a $1,000 attachment package and $400 delivery would total about $21,828 with 7% tax. A used unit listed at $8,000 with a $250 inspection and $500 in initial service would cost about $8,750 before any tax or unexpected repairs.
These examples show how attachments and dealer charges can change the final budget. Local sales tax treatment and whether advertised prices include setup vary, so buyers should request a written out-the-door quote.
Which add-ons are worth including in the budget?
Common additions include a mulching kit, grass catcher, hitch, extra blades, and a suspension seat. Depending on configuration, a mulching kit may cost roughly $150-$400, while a bagger or collection system can run $600-$1,500 or more. Prices vary with deck compatibility and whether installation is included.
Routine upkeep also belongs in the ownership budget. Oil, filters, blades, belts, and seasonal service can add about $150-$700 per year, depending on hours and whether maintenance is performed by the owner or a dealer. Commercial use and rough terrain can increase wear.
Price only accessories that match the mowing conditions. Collection equipment is useful when clippings must be removed, but unnecessary for many properties where clippings can be discharged or mulched.
How to lower the Z900 price without cutting useful features
Ask dealers to quote the same model with and without accessories, delivery, and extended coverage. If a smaller deck fits access points and acreage, it may avoid paying for capacity that will not improve the job. For a used mower, inspection and documented maintenance are more valuable than a low price with unknown service history.
Consider timing purchases around inventory changes, but weigh any discount against the value of having the mower during peak mowing season. Confirm whether a promotion applies to the selected model and whether financing charges change the total paid.
The strongest savings usually come from choosing the right deck and comparing complete written quotes. Avoid removing useful safety or service items just to lower the initial number; compare total ownership expense and warranty terms as well as purchase price.
