A hydraulic excavator includes an engine, a selective catalytic reduction apparatus, an outer cover, a first column member, a reducing agent tank, and a reducing agent pump. The selective catalytic reduction apparatus processes exhaust from the engine. The first column member supports the outer cover. The reducing agent tank retains a reducing agent. The reducing agent pump supplies the reducing agent from the reducing agent tank to the selective catalytic reduction apparatus. The reducing agent pump is attached to the first column member. |
