Deck and attachment fit
- Read the tractor PIN and match it to the correct manual.
- Identify whether the machine has a 48-, 54- or 60-in. deck before choosing blades, belts or deck parts.
- Check mounting parts, hydraulic couplers, PTO and ballast requirements for the exact attachment.
- Use Deere’s serial-aware catalog or dealer confirmation for any substituted part.
Used X739 checks
Ask for service records and note changes to the engine, deck or hydraulic equipment. Inspect for visible leaks, cooling-system obstruction, wiring damage, worn tires and missing guards. If the seller demonstrates it, observe four-wheel drive, steering, braking and PTO operation from the operator’s seat and follow the manual. Refer unusual behavior or warning indicators to a qualified technician.
