Bobcat’s plan for Tier 4 solutions includes a Doosan-built engine added to some of its equipment lineup starting in early 2014. Development of the new Tier 4-compliant, non-DPF (diesel particulate filter) engine was a collaboration between engineers from Bobcat, Doosan (Bobcat’s parent company), and engine-development companies such as Ricardo and FEV. Bobcat says its customers and dealers prefer a non-DPF engine because it minimizes long-term Tier 4 parts and maintenance expenses, and reduces daily maintenance requirements and complexity. Three Doosan engine models will be available, between 1.8- to 3.4-L displacement and 33 to 99 hp (25 to 74 kW). The company will continue to provide parts, service, and warranty on Kubota engines, which represent the largest number of engines in Bobcat machines. Kubota engines will still be offered in select products. Bobcat plans to release more details—engine specs and customer features and benefits—on its Tier 4 machines and their engines over the next 18 months.
