Bobcat T300 T300H Track Loader Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The Bobcat T300 and T300H are heavy-duty vertical-lift track loaders designed for demanding construction, landscaping, and industrial material handling applications. Manufactured by Bobcat Company (a subsidiary of Doosan Infracore, now part of Develon), the T300 delivers impressive lift capacity and reach that surpasses comparable wheeled skid steer loaders, particularly on soft, muddy, or uneven terrain where rubber tracks provide superior flotation and traction. The T300 features a rated operating capacity exceeding 3000 pounds with operating weights in the 10,000 pound class range. The vertical-lift path design provides maximum lift height and forward reach at full extension, making these machines ideal for truck loading, pallet handling, and placing materials at elevation. Power is delivered through a turbocharged diesel engine coupled to a hydrostatic drive system, providing smooth infinitely variable speed control in both forward and reverse. The T300 features an advanced control system with selectable joystick controls and advanced control system options for precise machine operation. The enclosed operator cab provides rollover and falling object protection with climate control options. Bobcat T-Series loaders are built at the companys manufacturing facility and are supported by an extensive global dealer network with genuine parts availability.
