Verify the mower and attachment setup
- Match the tractor PIN and model year to the correct manual and parts catalog.
- Record the mower deck identifier; do not assume the tractor specification sheet establishes the deck fitted to a used unit.
- Check attachment mounting parts, hydraulic connections and PTO details in the manual for that configuration.
- Confirm replacement engine or transmission work from service records and the component data plates.
Used X734 screening
Look over the machine for visible leaks, damage, missing guards, radiator obstruction and signs of wiring repair. Ask for service records and any engine or attachment changes. If operation is demonstrated, observe steering, drive, brakes and PTO from the operator’s position and follow the manual. Have a Deere dealer or qualified technician inspect warning lights or abnormal operation.
