Cub Cadet RZT S46 Used (Price & Value Guide)
A used Cub Cadet RZT S46 may be worth about $300–$800 as a rough or non-running project, $800–$1,500 with notable wear, or $1,500–$2,500 if sound and serviced. These are broad U.S. private-party screening ranges, not a live appraisal. Confirm its identity, test the deck and drive, and price in repairs before making an offer.
A mower can look clean and still hide a weak drive, worn deck parts, or a safety switch someone has bypassed. That makes the asking price only a starting point. I use the mower’s condition and a controlled operating test to judge whether a listing is a workable purchase or a costly repair project.
Used RZT S46 price ranges
These ranges provide a first screen for U.S. private-party listings. They are not guaranteed sale prices or a substitute for local comparisons. Year, engine hours, service history, season, local demand, and repair needs can move value substantially, so compare similar machines and verify what each one actually includes.
| Condition | Broad screening range | What to verify |
|---|---|---|
| Rough, non-running, or major-repair candidate | $300–$800 | Whether the engine, deck, or drive needs major work |
| Runs, but has notable wear or repairs due | $800–$1,500 | Whether it cuts and drives correctly; what maintenance is overdue |
| Sound, serviced machine with functional deck and drive | $1,500–$2,500 | Cold start, service records, safe controls, and a complete operating test |
| Exceptional condition or dealer-backed sale | May exceed $2,500 | Warranty terms, documented service, and local comparable prices |
A seller’s description is not a mechanical inspection. “Runs great” does not tell you whether the mower tracks straight, cuts evenly, or still moves reliably after its drive warms up. Use the ranges to decide what to inspect, not as proof that a machine is worth a particular amount.
Before paying, compare several local listings for RZT S46 machines with similar condition and equipment. A listing price is not necessarily the final sale price. If you cannot confirm a needed repair or its cost, treat it as uncertainty rather than assuming it will be a cheap fix.
Identify the mower and prepare safely
The RZT S46 is a gasoline, four-stroke, steering-wheel-controlled zero-turn mower with a 46-inch cutting width. The name alone does not identify every engine, transmission, or part. Record the mower’s model and serial numbers, and check the engine and deck labels before relying on service details or ordering parts.
Ask the seller for clear photos of the mower identification label, engine label, and deck label. Record the hours if an hour meter is fitted, but do not treat the display as a full service record. Compare labels and visible parts; mismatched components or missing labels make it harder to confirm the right manual and replacement parts.
This engine uses gasoline, not a chainsaw-style premixed fuel-and-oil blend. Engine make, oil grade, and oil capacity can vary, so check the engine label and the manual matched to the model and serial number. Likewise, confirm the deck model before ordering blades or belts. Do not guess blade length, blade count, belt routing, or engagement method from the mower name.
Prepare for an inspection on level, open ground. Ask the seller not to start the mower before you arrive so you can check a cold start. Keep bystanders clear, and do not test a mower with missing deck guards, damaged blades, or bypassed operator-presence safety switches.
Inspect condition before starting
A visual check can reveal wear and damage, but it cannot prove that the mower will work under load. Look over the frame, steering linkages, tires, wiring, fuel lines, engine, deck shell, and discharge chute before you start it. Focus on cracks, leaks, corrosion, loose parts, and repairs that could affect safe operation or value.
Check for welded cracks in the frame or deck, corrosion that has perforated metal, and oil or fuel leaks. Look at the tires for damage and uneven wear. Inspect visible wiring and fuel lines for damage or poor repairs, and check that the seat and its operator-presence switch appear intact. Do not accept a seller’s promise that a bypassed switch is a simple fix.
With the mower off, look under the deck only when it is safe to do so and the key is removed. Check for obvious blade damage, missing guards, belt wear, and loose or damaged spindle areas. A spindle is the rotating assembly that holds a blade; roughness, looseness, or damage may point to repair needs. Keep hands away from blade edges.
| Inspection area | Better signs | Reasons to pause or lower your offer |
|---|---|---|
| Frame and deck | No visible cracks or perforating rust | Welded cracks, bent areas, or holes from corrosion |
| Engine and fuel system | No visible leaks; starts from cold | Leaks, damaged fuel lines, heavy smoke, or unclear engine identity |
| Steering and tires | Similar response left and right; sound tires | Loose linkages, damaged tires, or uneven steering |
| Deck and belt area | Guards present; no obvious damage | Missing guards, damaged blades, or signs of loose or worn parts |
| Safety equipment | Operator-presence controls appear intact | Bypassed, damaged, or missing safety switches |
A clean exterior should not outweigh a structural problem. If you find a serious defect, stop and decide whether you have the skills, parts information, and repair estimate to take it on.
Test the engine, controls, deck, and drive
A brief start-up is not enough to judge a used zero-turn mower. Follow the operator’s manual for starting and operation. Check the controls at low speed on level ground, then see whether the mower behaves consistently after several minutes. Never test the deck without its guards or with people nearby.
Before starting, check the oil and fuel condition using the manual’s instructions. Note whether the engine starts from cold and how it responds to the manual’s starting procedure, including choke or throttle settings when applicable. Watch for leaks, unusual noise, or excessive smoke. Do not diagnose a fault based on one symptom alone.
Check the parking brake and operator-presence interlocks as described in the manual. If a safety switch has been bypassed, do not operate the mower. Confirm that blade engagement works only as intended and that any charging indicator fitted to the machine behaves as described in its manual.
On level, open ground, test forward and reverse at low speed. Check both directions and make turns each way, then observe whether the mower tracks straight and responds smoothly to steering. Listen for abnormal hydrostatic whining, look for leaks, and note vibration or belt slip. If conditions are safe and the seller permits, repeat the drive check after several minutes.
A machine may move during a short test yet lose power, pull, or behave inconsistently as it warms. Persistent drive noise, leakage, or unequal movement can point to a costly transmission, linkage, or hydraulic-system problem. Do not assume an unexplained drive fault will be fixed by a simple adjustment.
If the deck can be tested safely, mow a small suitable patch of turf. Look for an even cut and listen for unusual vibration or belt slip. Do not use the mower on steep slopes, rough brush, or ground outside the operator’s manual limits.
Judge repairs and set an offer
A fair offer reflects the mower’s condition, not just its age or appearance. List each known repair, verify parts against the model, serial, engine, or deck information, and get a repair estimate when the problem is unclear. Subtract confirmed costs from the price you would consider fair for a comparable, working mower.
The examples below are hypothetical buying scenarios, not reported sales or appraisals. They show how an inspection can change a decision within the broad screening ranges. Your local listings and actual repair quotes should guide the final offer.
| Hypothetical inspection | What the test finds | How to use the price guide |
|---|---|---|
| Non-running machine | Engine will not start; cause is unknown | Consider the rough-project range only if you can assess the risk and repair cost |
| Running, worn machine | Starts, but has visible wear and maintenance due | Compare with the $800–$1,500 range, then account for verified work |
| Serviced machine | Starts cold, cuts, and drives consistently; records are available | Compare with the $1,500–$2,500 range and local examples |
Do not count an unknown fault as a confirmed low-cost repair. If the drive behaves inconsistently, the engine smokes heavily, or the deck has structural damage, ask for an inspection by a qualified repair shop or walk away. A bill of sale and proof of ownership also matter; verify the seller’s right to sell before paying.
Maintain value after purchase
A sound purchase still needs routine care. Use the operator’s manual for the exact mower and the engine manual for engine service. Keep records of oil and filter work, blade service, belt or spindle repairs, and any problems you find; records help with future maintenance and make later resale clearer.
Before the mowing season, inspect the deck, guards, blades, tires, fuel lines, wiring, steering, and safety controls. Check fluids and service intervals in the correct manuals. Replace blades only with parts that match the deck identification and parts diagram. Do not use a generic RZT S46 label to guess part numbers or service capacities.
Before storage, follow the manuals for fuel, engine, and battery care, as applicable to the specific machine. The engine is four-stroke, so do not mix oil into gasoline. If the mower has been sitting and will not start, check basic items using the manual before replacing parts; fuel condition, battery state, or a service issue may be involved.
Frequently asked questions
These answers cover the most common buying questions, but they cannot replace the correct operator’s manual or an in-person inspection. For specifications and replacement parts, use the mower’s model and serial numbers, plus the engine or deck identification where relevant.
What is a used Cub Cadet RZT S46 worth?
Broad U.S. private-party screening ranges are $300–$800 for rough or major-repair machines, $800–$1,500 for running machines with notable wear, and $1,500–$2,500 for sound, serviced examples.
Is the RZT S46 a zero-turn mower?
Yes. It uses a steering-wheel-controlled zero-turn configuration. Check for smooth, balanced steering and movement in both directions.
How wide is the RZT S46 cutting deck?
The stated cutting width is 46 inches. Confirm the deck identification label before ordering blades, belts, or other deck parts.
Can I mix two-cycle oil into its gasoline?
No. It has a four-stroke gasoline engine. Check the engine manual for the correct oil grade, capacity, and service steps.
Does every RZT S46 use the same engine and transmission?
Do not assume so. Engine, transmission, and service details can vary by production year. Verify the mower and engine labels and use the matching manuals.
What should I check first when viewing one?
Start with identification labels, frame and deck condition, leaks, safety switches, and steering linkages. Then arrange a cold start and controlled operating test.
How can I test the drive?
On level, open ground, test forward, reverse, and turns at low speed. Check both directions again after several minutes and watch for pulling, loss of power, leakage, or persistent unusual noise.
Is a drive problem likely to be a simple adjustment?
There is no reliable way to assume that from a listing or brief test. Inconsistent movement, leaks, or ongoing noise may signal costly repairs, so get a diagnosis before buying.
Can I test it with a missing deck guard or bypassed switch?
No. Do not operate a mower with missing guards or bypassed operator-presence interlocks. Ask the seller to restore safe function before any test.
What should I verify before completing the sale?
Confirm ownership, obtain a bill of sale, and keep the model and serial information, manuals, service records, and any repair estimates.
