A used Cub Cadet RZT 42 typically costs about $700-$2,500, with many serviceable machines selling near $1,400 depending on age, condition, engine, and included accessories. The model is discontinued, so price comparisons often include current 42-inch Cub Cadet zero-turn mowers, delivery, and any repairs needed before mowing.

What a 42-inch RZT usually costs used
Most buyers should budget $1,000-$2,000 for a running RZT 42 in ordinary working condition. At the low end, roughly $700-$1,000, expect an older mower, visible wear, an urgent sale, or maintenance due. A clean, tested machine with good tires, blades, and seat can reach $1,700-$2,500, especially where used zero-turns are in short supply.
These are practical U.S. market estimates, not a fixed national list price. The RZT 42 was sold in different years and configurations, and a listing may omit the exact model year or engine details. Confirm the model and serial information before comparing prices. A mower with an unfamiliar engine specification or incomplete maintenance history should not automatically command the same price as a documented, well-kept example.
The 42-inch deck is suited to residential mowing where a zero-turn’s maneuverability is useful, but it does not make every RZT 42 equally valuable. Engine starts, hydrostatic drive performance, deck condition, and repair history can matter more than a seller’s description of the mower as lightly used. A machine that needs a major drive or engine repair may be worth less than a cosmetically rough mower that operates reliably.
Assumptions: used mower has a complete 42-inch deck, starts and cuts, has no known major mechanical fault, and is bought in a typical U.S. market.
How mower condition changes the asking price
Mechanical condition can shift the price by hundreds of dollars because repairs quickly erase the apparent savings. A clean machine that starts cold, idles evenly, drives straight, and engages its deck is more valuable than one that only starts after warming up. Ask the seller to demonstrate it mowing, not just running in place.
Inspect the deck shell for rust-through, cracks, bent edges, and uneven wear. Surface rust is usually less serious than a thin deck that has corroded around the spindle mounts. Check blade spindles for wobble or grinding, and look for fresh welding or patched metal. Uneven cutting may be caused by blades or deck setup, but it can also point to damaged components.
Test both drive controls through forward, reverse, and gentle turns. A zero-turn that pulls to one side, creeps when controls are neutral, or loses drive after warming up deserves further diagnosis. Look for oil leaks around the engine and hydrostatic units, and inspect belts for fraying. A short test cannot prove long-term reliability, but it can identify reasons to lower an offer or walk away.
Documented oil changes, replacement belts, battery age, and deck service can support a higher price. Missing paperwork does not prove neglect, but it should temper the offer. A seller who cannot identify the model year, explain a recent repair, or permit a safe operating test leaves the buyer with more uncertainty and should not be priced like a dealer-serviced unit.
What dealer and private-party quotes include
The advertised mower price may exclude delivery, tax, setup, and repairs, so compare the complete out-the-door amount. Private sellers often offer a lower starting price but little recourse if a fault appears. Dealers may charge more for inspection, preparation, and a limited warranty, though the exact coverage should be written on the invoice.
| Quote item | Private-party range | Dealer range | What changes the charge |
|---|---|---|---|
| Mower itself | $700-$2,500 | $1,200-$2,800 | Condition, service history, warranty, and local inventory |
| Inspection or setup | $0-$100 | $75-$250 | Inspection depth and included adjustments |
| Delivery | $50-$200 | $75-$300 | Distance, trailer availability, and access |
| Routine service | $100-$300 | $150-$400 | Oil, filters, blades, battery, and labor included |
| Tax and registration-related charges | $0-$250 | $0-$350 | State and local tax rules and transaction amount |
There is no universal registration charge for a residential riding mower, but sales tax may apply based on the buyer’s location and transaction. Ask whether a dealer’s setup fee includes inspection, fluids, blade sharpening, and a test cut, or merely assembly and paperwork. For a private purchase, price transport separately if the mower cannot be driven safely onto a trailer.
For repair work, small-engine labor commonly runs about $75-$125 per hour, with shop minimums or diagnostic fees sometimes adding $50-$125. A one-hour adjustment can be inexpensive, but several hours tracing an intermittent electrical or drive problem can change the economics of a low-priced machine.
Which RZT 42 details move the estimate
Age, deck integrity, and hydrostatic transmission behavior are the largest practical price drivers. Two mowers with the same 42-inch deck can differ substantially if one has a documented service record and the other has been stored outdoors with uncertain maintenance. Ask for the model number, serial number, engine information, and any repair receipts before settling on a value.
Hours on the meter can help, but they are not a complete measure of wear. A higher-hour mower with regular service and an intact deck may be a safer buy than a low-hour example with damaged spindles or neglected fluids. If there is no hour meter or its accuracy is unclear, treat seller statements about usage as unverified rather than assigning a precise premium.
Deck repair is another threshold to consider. Replacing blades or a belt is a routine expense; repairing a cracked or badly corroded deck can be uneconomical. A rough planning allowance is $40-$100 for a set of blades, $30-$100 for a belt, and $150-$500 or more for a spindle or substantial deck work, including labor where applicable. Parts availability and local shop rates vary.
Engine symptoms also affect the quote. A battery or routine ignition service may be a modest fix, while low compression, persistent smoke, or a knocking sound can signal a costly engine problem. Before buying, compare the repair estimate with the price of a functioning mower. If the seller will not permit a cold start or a drive-and-cut test, discount the offer for the added risk.
How to lower the total without skipping essential checks
Negotiate against documented repair needs, not appearance alone. Bring a written list of parts or service required and get a local repair estimate before agreeing on a price. A mower with worn blades may be a reasonable buy at a modest discount; one with slipping drive, a damaged deck, and engine smoke may not be a bargain even at a low asking price.
Ask whether the sale includes the grass catcher, mulch kit, spare blades, or owner’s manual, and verify that each accessory fits this model. Do not pay extra for an attachment that will not be used. If accessories are missing, check their current availability and cost before treating the mower as a complete package.
Picking up the mower can save a delivery charge if a suitable trailer and secure loading equipment are available. A zero-turn mower is heavy, and improvised ramps or an unsuitable vehicle can create injury and equipment risks. If transport is uncertain, include professional delivery in the budget rather than assuming it will be free.
Compare at least three local listings and ask for the actual sale price when possible. A seller’s asking price is not a confirmed market value. A dealer quote is most useful when it itemizes inspection, warranty, delivery, and service; a private-party comparison should account for the buyer’s likely maintenance costs and lack of warranty.
RZT 42 versus a current 42-inch zero-turn
A used RZT 42 can cost substantially less upfront, but a new mower offers current condition and clearer warranty terms. Comparable new 42-inch residential zero-turn models commonly list around $3,000-$4,000 before delivery and applicable tax, depending on model series, features, and dealer pricing. Promotions and regional inventory can move the final quote outside that range.
For a used RZT priced at $1,400, adding $250 for pickup and initial service brings the working budget to about $1,650 before unexpected repairs. That remains below a typical new-machine price, but the buyer accepts more uncertainty about remaining life and future parts or labor. A dealer-serviced used unit priced near $2,500 may be less compelling if a new mower is available nearby with a meaningful warranty.
Repairing an owned RZT can beat replacement when the mower is structurally sound and the fault is limited to routine service or a modest component. Compare a written repair estimate with the total cost of another used machine, including pickup and immediate maintenance. Engine, transmission, or deck repairs may make replacement more sensible when several major systems need attention at once.
Warranty coverage matters as much as the label on the price. Confirm whether a used dealer warranty covers engine, drive system, and labor, and check exclusions and duration. A private seller’s verbal assurance is not equivalent to written coverage. For a new model, ask for the manufacturer’s warranty terms and whether the dealer charges separately for delivery or setup.
How location and delivery affect the price
Regional demand can move used asking prices by roughly 10%-25% compared with a broad local baseline. Areas with long mowing seasons, large suburban lots, and active lawn-equipment markets may have more listings but also stronger demand. In colder regions, winter listings can be more negotiable, while early spring often brings more competition as buyers prepare for the season.
These percentages are useful comparison allowances, not guaranteed regional price rules. Local supply, population density, and condition can outweigh climate. Rural buyers may face fewer nearby listings and longer transport distances; metropolitan buyers may have more choices but higher dealer labor or delivery charges. Compare similar machines within a practical pickup radius before assuming a national estimate fits.
Delivery commonly adds $50-$300 for a local trip, with longer distances, difficult access, or special loading needs potentially costing more. Confirm that the quote covers loading, unloading, and delivery to the desired location. If the mower must be moved across state lines or hauled a long distance, request a firm transport price before sending a deposit.
Sales tax depends on state and local rules and can add several percent to a dealer purchase. Ask for an itemized out-the-door quote rather than comparing a pre-tax advertised price with a tax-inclusive private sale. A dealer may also charge setup or documentation fees; request the amount and included work in writing.
What repair budget should follow the purchase
Set aside $150-$400 for ordinary catch-up service and more if the seller cannot demonstrate a complete operating test. A basic service might include oil, filters, spark plugs, blades, and battery checks. Costs depend on whether the buyer performs the work or pays a shop, and whether replacement parts are standard or specific to the mower’s configuration.
For a shop visit, ask about diagnostic charges, minimum labor, and whether the fee is credited toward approved work. Routine labor may take 1-3 hours, while diagnosing a difficult electrical, engine, or drive complaint can take longer. At $75-$125 per hour, a three-hour repair can cost $225-$375 in labor before parts, making an initial inspection worthwhile when the machine’s history is uncertain.
Have the shop test the mower under load, inspect the deck and drive components, and identify safety-related issues such as faulty controls or damaged guards. A seller’s recent tune-up receipt is useful, but it may not cover deck wear or transmission behavior. Request a written estimate that separates parts, labor, and optional work so the buyer can decide what must be done immediately.
Do not budget based on the assumption that every used mower needs a major repair. Instead, use a reserve appropriate to the evidence: closer to $100-$200 for a clean, tested machine with records, and $300-$700 for one with unknown maintenance or visible deferred work. Those reserves are planning amounts, not a prediction that every RZT 42 will require repairs.
Questions to ask before paying for an RZT 42
A short, specific inspection can prevent a low advertised price from becoming an expensive project. Ask the seller to identify the model and year, explain how long they have owned it, and list recent repairs. Request a cold start, then test forward and reverse movement, steering response, blade engagement, and a short cut if the seller permits it safely.
Ask whether the deck has been welded, whether the mower has been stored indoors, and whether any drive or engine components have been replaced. Request receipts for recent service and confirm what accessories are included. Check that the machine’s identification information is legible and consistent with the seller’s paperwork.
For dealer sales, ask exactly what the inspection covers and whether the warranty applies to parts, labor, engine, and transmission. For private sales, clarify whether the price is firm and whether loading assistance is available. Neither a detailed listing nor a clean exterior guarantees mechanical condition; an operating demonstration and independent inspection provide better evidence.
If the seller cannot answer basic questions, declines a test, or pressures for a deposit before the mower is inspected, use a more conservative price ceiling. The purchase budget should include tax where applicable, transport, immediate service, and a repair reserve. That full-cost comparison is more useful than choosing the lowest sticker price.
