The Mule PRO-DX EPS is our powerful, most capable, full-size, three-passenger diesel Mule Side x Side yet. This high-capacity diesel Mule has the largest steel cargo bed in its class so you can easily load a full-size wooden pallet (40 x 48 inches) and up to a 1,000-pound cargo bed capacity (600 lb. maximum cargo bed capacity for California models) then close the tailgate for transport.
