A tension adjustment assembly for a tracked vehicle, the tracked vehicle including a frame, an endless track, a track-engaging wheel supported by the frame, and a second track-engaging wheel supported by the frame in spaced relation to the first track-engaging wheel. The first track-engaging wheel and the second track-engaging wheel are rotatable about a first axis and a second axis, respectively. The endless track extends about the first track-engaging wheel and the second track-engaging wheel, and the track has a tension. The first track-engaging wheel is movable relative to the frame in a direction perpendicular to the first axis to adjust the tension of the track. The assembly further comprises a tension adjustment mechanism connected to the first track-engaging wheel and operable to move the first track-engaging wheel, the tension adjustment mechanism including a rotatable member rotatable about a rotational axis to cause movement of the first track-engaging wheel relative to the frame. The assembly also includes a shaft rotatably supported by the frame for rotation about a shaft axis generally transverse to the rotational axis; and a coupling connected between the shaft and the rotatable member to translate rotation of the shaft into rotation of the rotatable member to thereby move the first track-engaging wheel and adjust the tension of the track.
