The Cub Cadet RZT 42 is a popular zero-turn riding lawn mower. The RZT 42 is powered by a 17-hp Kohler Courage OHV single cylindar engine that has ample power and lots of design features to make it a long-term mower. Dual hydrostatic transmissions control the two rear wheels, making maneuverability easy. Forward speed is 5-1/2 mph and reverse speed is 3 mph. The 42-inch cut is made by two belt-driven blades below the deck, which are easily engaged and disengaged with the handy electric PTO switch. Two adjustable-gauge wheels are located at the rear of the deck to reduce scalping or cutting the lawn too low.
