Abstract: Interchangeable track systems for interchangeable deployment with vehicle wheels on a forestry harvester vehicle having a front axle and a rear axle may include a pair of front roller frame mount arms and a pair of rear roller frame mount arms configured for mounting on the front axle and the rear axle, respectively. A pair of front track assemblies and a pair of rear track assemblies may be configured for removable mounting on the pair of front roller frame mount arms and the pair of rear roller frame mount arms, respectively. Each of the pair of front track assemblies and the pair of rear track assemblies may include an elongated roller frame configured for pivotal attachment to the corresponding one of the pair of front roller frame mount arms and pair of rear roller frame mount arms. A front idler roller and a rear idler roller may be carried by the roller frame. A track may be trained on the front idler roller and the rear idler roller.
