Chassis and Operator Environment
Built with a four-wheel-drive system, the tractor includes power steering and mechanical wet disc brakes for operator control. The standard configuration utilizes a two-post Roll-Over Protective Structure (ROPS). An optional climate-controlled cab is available to enhance operator comfort in varying weather conditions.
