John Deere's Gator utility vehicles include a range of models in three series: Compact, Traditional and High Performance. Shown here is the Gator TH 6×4, which is powered by an air-cooled, two-cylinder Kawasaki engine and uses a continuously variable transmission that provides a forward top speed of 19.4 mph. The rear wheels provide full-time four-wheel drive, and a traction-assist feature locks the drive wheels together for extra push through tough spots. The cargo box handles loads up to 1,000 pounds.
