Abstract

The present invention addresses the problem of providing an exhaust treatment unit capable of improving the maintainability of a diesel particulate filter. This exhaust treatment unit for treating the exhaust from the engine of a work vehicle is equipped with a diesel particulate filter device, a selective reduction catalyst device, a first support component and a second support component. The diesel particulate filter device and the selective reduction catalyst device treat the exhaust. The first support component supports the diesel particulate filter device, while the second support component supports the selective reduction catalyst device and the first support component. The first support component can be attached to and detached from the second support component.
