Toro considers its 3000 and 4000 Workman Series the heavy-duty performers in its utility-vehicle lineup. At the top of this range is the 4300-D, an on-demand-four-wheel-drive vehicle with a 26.5-hp Daihatsu diesel engine and a three-speed, two-range rear transaxle. An optional high-flow-hydraulics kit (8 gpm at 2,000 psi) is available for powering attachments. Safety features include an integral rollbar, shoulder and hip restraints, and an interlock system.
