517 Track Skidder Power Train The field proven Cat® 3304 DIT Diesel engine, heavy-duty torque converter and three-speed transmission are matched to deliver high horsepower for more drawbar pull, improved skidding performance and ease of operation. Application Flexibility The 517 Skidder provides unsurpassed performance and application flexibility due to superior balance, torque converter power train and expanded track and grapple/arch options. The versatile PAT blade makes the 517 a multi-purpose machine. Undercarriage Use of D5H sized heavy-duty track prolongs the life of the key undercarriage components, including rollers, idlers, pins, bushings and shoes. An extended track roller frame places more track under grapple/winch and enhances balance. Hydraulics The load sensing hydraulic system reduces horsepower consumption and system heat. A single lever controls grapple and tong hydraulics, reducing operator efforts for improved productivity. Exclusive Auto-Grab hydraulics maintain constant tong gripping pressures to compensate for shifting loads. Operator Station Excellent all-around viewing area, angled seat, and easy-to-reach controls reduce operator fatigue and increase productivity. Available with enclosed cab or open canopy. Cable Skidder The 517 is also offered in a cable configuration to meet application demands in severe slope and mountainous terrain. Serviceability Less service time means more working time. Major components are made as modules and most can be removed without disturbing or removing others.
