Track system

A track system for use with a vehicle having a chassis and a drive shaft extending laterally outwardly from the chassis for driving the track system, the track system comprising:

• an attachment assembly connectable to the chassis of the vehicle, the attachment assembly having a leading pivot and a trailing pivot extending laterally outwardly therefrom;
• a multi-member frame assembly disposed laterally outwardly from the attachment assembly, the multi-member frame assembly including:
• a leading frame member pivotably connected to the attachment assembly via the leading pivot for pivoting about a leading pivot axis;
• a trailing frame member pivotably connected to the attachment assembly via the trailing pivot for pivoting about a trailing pivot axis;
• a leading wheel-bearing frame member at least indirectly pivotably connected to the leading frame member;
• a trailing wheel-bearing frame member at least indirectly pivotably connected to the trailing frame member;
• a damper interconnecting the leading frame member and the trailing frame member;
• a leading idler wheel assembly rotatably connected to the leading wheel-bearing frame member;
• a trailing idler wheel assembly rotatably connected to the trailing wheel-bearing frame member;
• a plurality of support wheel assemblies disposed intermediate the leading idler wheel assembly and the trailing idler wheel assembly;
• a gearbox having an input shaft operatively connectable to the drive shaft of the vehicle and an output shaft;
• a sprocket wheel operatively connected to the output shaft of the gearbox;
• and
• an endless track extending around the sprocket wheel, the leading idler wheel assembly, the trailing idler wheel assembly, and the plurality of support wheel assemblies, and drivable by the sprocket wheel.
