PROBLEM TO BE SOLVED: To prevent interruption of a tractor work as much as possible by efficiently supplying urea water.SOLUTION: A tractor on which a diesel engine E and a urea selective catalytic reduction SCR system are mounted is provided.The tractor comprises: a fuel tank 3 for mounting fuel thereon; a urea water tank 80 for mounting urea water thereon; a fuel level sensor 3a for measuring fuel amount in the fuel tank 3; and a fuel display meter 3b for indicating an amount of fuel. The tractor is configured in such a way that: when fuel amount is reduced to a prescribed amount, informing means 79 at an operator's seat displays an instruction of promoting supplementation of urea water; and when a workable time T2 with fuel becomes longer than a workable time T1 with urea water, the informing means 79 at the operator's seat is caused to prompt supplementation of urea water.SELECTED DRAWING: Figure 8 |
