Maneuverability and Chassis
The 620-Z features a two-wheel drive configuration paired with power steering to facilitate the zero-turn capability. The operator operates from an open station designed for visibility. The unit is supported by 11x4.00-5 front tires and 18x9.50-8 rear tires, specifically designed for lawn and turf applications to minimize surface disruption.

The tractor has a wheelbase of 42 inches (106 cm), a total length of 71.9 inches (182 cm), and a width of 40 inches (101 cm). With an overall height of 41.2 inches (104 cm) and a weight of 720 lbs (326 kg), it maintains a low center of gravity for stability.
