1. An auxiliary track device for use with a vehicle comprising:
a first track system and a second track system each comprising a track for engaging the ground and a track-engaging assembly for driving and guiding the track;
a support for connecting the auxiliary track device to the vehicle and supporting the first track system and the second track system; and
a powertrain configured to power a drive wheel of the track-engaging assembly of each of the first track system and the second track system;
wherein the support of the auxiliary track device comprises an attachment configured to be connected to a three-point hitch of the vehicle;
wherein the auxiliary track device is movable between a deployed position in which the auxiliary track device engages the ground and a retracted position in which the auxiliary track device is off the ground;
wherein the auxiliary track device is configured to be automatically moveable between the deployed position and the retracted position by a control system based on one or more sensed parameters of the auxiliary track device; and
wherein the one or more sensed parameters of the auxiliary track device comprise:
a speed of the track of the first track system around the track-engaging assembly of the first track system;
a speed of the track of the second track system around the track-engaging assembly of the second track system;
a direction of motion of the track of the first track system around the track-engaging assembly of the first track system;
a direction of motion of the track of the second track system around the track-engaging assembly of the second track system;
a tension of the track of the first track system around the track-engaging assembly of the first track system; and/or
a tension of the track of the second track system around the track-engaging assembly of the second track system.
