The T320 rubber-track loader from Thomas Equipment uses large-diameter drive sprockets that provide 180 degrees of track wrap around each sprocket. An internal drive system protects hydrostatic drive motors and hoses. No track-tension system is required because the machine has a three-piece front idler sprocket that allows the track to stay at proper tension after assembly. The track contains no steel and will always return to its original length, the company says. Estimated list price: $47,000.
