See the John Deere S240 listing for the current configuration and available options. Deck size, components and service information should be matched to the tractor’s serial record.
Check deck and part fit
- Record the tractor’s model year and product identification/serial number.
- Confirm whether the installed deck is 42 or 48 in.; do not order blades or belts from the tractor name alone.
- Match engine and transaxle service parts to the correct manual and serial range.
- Use Deere’s equipment selector before purchasing replacement parts or attachments.
Used S240 inspection
Review maintenance records and look for visible deck damage, leaks, corrosion, worn wiring and missing guards. If operation is demonstrated, observe starting, steering, braking and hydrostatic drive functions from the seat, following the operator’s manual. A listing photo or a replacement-part description does not confirm fit. Ask a Deere dealer to verify uncertain deck or serial compatibility.
