A work vehicle includes a frame, an axle, a cab supported by the frame, a first tuned mass damper assembly, and a second tuned mass damper assembly. The frame includes a first longitudinal frame member and a second longitudinal frame member. The first longitudinal frame member has a first rear end, and the second longitudinal frame member has a second rear end. The second longitudinal frame member extends parallel to the first longitudinal frame member. The axle extends perpendicular to the first and second longitudinal frame members. The cab is disposed on a side of the first and second longitudinal frame members opposite the axle. The first tuned mass damper assembly is mounted on the first longitudinal frame member between the first rear end and the cab. The second tuned mass damper is mounted on the second longitudinal frame member between the second rear end and the cab.
