IMPORTANT: (Final Tier 4 and Stage 4 Engines only. To determine which engine your tractor is equipped with, see Record Engine Serial Number in Identification Numbers section of this Operator's Manual.) Do not disconnect battery until Selective Catalyst Reduction (SCR) system has had enough time to automatically purge system of Diesel Exhaust Fluid (DEF) . If adequate time is not allowed for system to be purged, any DEF remaining can crystallize and plug system. At temperatures below -15°C (5°F), unpurged DEF will freeze and damage system components. If equipped with a battery disconnect system, a light next to disconnect system is illuminated while auto-purge is in progress. It shuts off when complete and safe to disconnect the battery.

If tractor is not equipped with battery disconnect switch, wait at least 4 minutes after tractor stops before disconnecting battery.

IMPORTANT: Ensure both negative (-) and positive (+) battery connections are disconnected from both batteries before fuse inspection or replacement.

Do not attempt to disassemble master fuses unless instructed by your John Deere™ dealer.

Replacement fuses must be the same rating as original.

Tractors have two or three master fuses. Fuse module is located inside battery compartment.
