Abstract: A work vehicle includes an engine, a diesel particulate filter apparatus, a connecting pipe, and a selective catalytic reduction apparatus. The diesel particulate filter apparatus treats exhaust from the engine. The connecting pipe connects the engine and the diesel particulate filter apparatus. The connecting pipe extends obliquely downward toward the diesel particulate filter apparatus from a connecting position with the engine. The selective catalytic reduction apparatus treats the exhaust from the engine. The selective catalytic reduction apparatus is arranged above the connecting pipe.

Abstract: A work vehicle includes a vehicle frame, a radiator, an engine, a first post-treatment apparatus, a second post-treatment apparatus, and a bracket. The engine is provided in front of the radiator. The first post-treatment apparatus and the second post-treatment apparatus are positioned in front of the radiator and treat exhaust from the engine. The bracket is positioned in front of the radiator and is elastically supported by the vehicle frame. The bracket supports the engine, the first post-treatment apparatus, and the second post-treatment apparatus. Both the highest position of the first post-treatment apparatus and the highest position of the second post-treatment apparatus are no higher than the highest position of the radiator.
