Battery Disconnect Switch

Never turn power off on the battery disconnect switch while the engine is running. This could result in serious damage to the tractor’s electrical components.

During a long storage period, always turn battery disconnect switch to OFF position. The battery could lose power if the battery disconnect switch is left ON.

(Final Tier 4 and Stage IV Engines only.) To determine tractor engine type, see Engine Serial Number in Identification Numbers section of this Operator's Manual. Do not disconnect battery until Selective Catalytic 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 DEF indicator light (C) 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.

Final Tier 4/Stage IV tractor battery disconnect system is equipped with a warning light. Do not move battery disconnect switch to OFF position until the light goes out. Illuminated light indicates SCR system is in process of draining DEF. Full DEF drain process can take up to 4 minutes.
