Abstract: An exhaust system with a multipiece heat shield for a work vehicle includes a first shield part and a second shield part. The first shield part surrounds an aftertreatment unit for aftertreating exhaust gases. The first shield part extends in an axial direction. The second shield part surrounds an exhaust tailpipe with radial spacing between the second shield part and the exhaust tailpipe. The second shield extends in the axial direction from the first shield part, wherein a radial gap between the first and second shield parts is sealed by a seal.

The second shield extends in the axial direction from the first shield part, wherein a radial gap between the first and second shield parts is sealed by a seal. In a starting position, the seal has two free ends arranged in the circumferential direction of the heat shield, which are arranged adjoining or overlapping one another in the circumferential direction when the seal is in a sealing position.
