A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.

A track system for traction of a vehicle that is connectable to an axle of the vehicle and includes a track and a track-engaging assembly for driving and guiding the track around the track-engaging assembly. The track-engaging assembly includes a drive wheel for driving the track, idler wheels for contacting a bottom run of the track, and a bogie carrying the idler wheels. The track system includes a transmission for transmitting power from the axle of the vehicle to the drive wheel such that a rotational speed of the drive wheel is different from a rotational speed of the axle of the vehicle. The track system includes a connector disposed between the transmission and the bogie such that the bogie is movable (e.g., pivotable) relative to the transmission. The connector may be disposed below an output shaft of the transmission.
