Disconnect Battery - Final Tier 4 and Stage IV Engines

IMPORTANT: To determine tractor engine type, see Record Engine Serial Number in Identification Numbers Section of this Operator’s Manual.

IMPORTANT: 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.
