A tracked vehicle includes a track operatively connected to a driveshaft. An output shaft of a hydrostatic motor is selectively rotationally engaged with the driveshaft via a clutch mechanism. When the clutch mechanism is engaged, the motor drives the track. When the clutch mechanism is disengaged, the tracked vehicle may be towed without rotating the output shaft of the motor. The clutch mechanism includes spline d surfaces on the driveshaft and output shaft that are adapted to rotationally engage a splined surface of an axially-movable clutch shaft. The clutch mechanism further includes an engagement controller that selectively axially moves the clutch shaft into and out of rotational engagement with the output shaft while maintaining continuous rotational engagement between the clutch shaft and the driveshaft.
