EXHAUST GAS TREATMENT DEVICE OF COMBINE

摘要

PROBLEM TO BE SOLVED: To continue reaping and harvesting work without making an operator confused by notifying the operator that the filtering function regeneration of a diesel particulate filter (DPF) is automatically started in an easily-understandable manner.SOLUTION: There is provided an engine exhaust gas treatment device of a combine which comprises: an engine; a DPF for purifying an exhaust gas discharged from the engine; deposit amount measuring means which detects a deposit amount of particulate matters in the DPF; and controller 15 which automatically starts regeneration control for removing PMs deposited in the DPF by raising an engine rotation number up to a prescribed regeneration rotation number higher than a notified rotation number after lowering the engine rotation number to a prescribed notified rotation number once when the deposit amount of the particulate matters detected by the deposit amount measuring means reaches a prescribed amount.
