Tigercat has developed a dedicated processor carrier designed for roadside processing applications as well as light duty in-woods harvesting, which is being marketed worldwide with units sold and operating in such diverse areas as the US, Uruguay, South Africa and Australia.

The H250B was developed from the T250B loader platform and offers harvesting contractors a lower cost alternative to Tigercat’s 800 series harvesters while providing superior productivity in roadside processing applications compared to excavator conversions, according to the company. The H250B is powered by a turbocharged and aftercooled Tier III Cummins QSB6.7 engine, delivering 153 kW at 1,800 rpm. The high horsepower ensures that the carrier can operate the processing attachment to its full capacity, providing greater productivity. The lower engine rpm reduces fuel consumption as well as noise levels. According to designer Trevor Scott, the hydraulic system is tailored for processing applications. The hydraulic pump and valves can provide 360 L/min of flow and up to 290 bar pressure to the attachment. “The engine power ensures that the carrier can deliver high flow and high pressures simultaneously and maintain processing performance levels under tough conditions,” he said. “The load sense valves and pumps provide a system that can save fuel by delivering only the pressure and flow required by the functions.” Hydraulic hoses and tubes have been sized to handle the high flow required by these attachments and to provide low pressure drop at these levels. This results in added performance and productivity or reduced fuel consumption. Specifically designed for processing applications, the boom system provides a 9.68 m reach and a lift capacity suitable for attachments weighing up to 4 000 kg. The boom geometry also allows for convenient machine transport. The D6 undercarriage, upper assembly and cab are all designed for forestry use, offering greater strength and durability than excavator conversions without the need for additional guarding or protection. High capacity cooling ensures that engine and hydraulic oil temperatures remain cool even under extreme conditions, extending the life of major components.
