Four cylinder, four stroke engine and heavy-duty torque converter significantly improve skidding performance.
Turbocharged Cat 3304 DIT diesel engine sets the industry standard for reliability and durability.Torque Converter
Large, heavy-duty torque converter is matched to the 3304 engine power for excellent drawbar pull and improved skidding performance.Radiator
Six-row radiator core has large surface areas for improved heat rejection.Transmission
Three-speed planetary power shift transmission is designed and built by Caterpillar and delivers three speeds in both forward and reverse.
The 517 Skidder can easily handle an array of tasks and applications for today's loggers.
Maximum skidding performance is best attained through the available swing boom and grapple.Horsepower and Torque
High horsepower and torque further enhance the 517's dozing abilities.Track Options
Expanded track options allow the 517 to maintain skidding performance and minimize ground disturbance in a wide range of ground conditions.Ground Clearance
Excellent ground clearance allows the 517 to readily avoid obstacles, maneuver in poor underfoot conditions, and work effectively and efficiently on snow covered sites.
Undercarriage options provide optimized performance and durability, while allowing customization for different logging applications.
Track Roller Frame
Heavy-duty track roller frame and undercarriage are key to the 517's superior balance and durability.Supported Undercarriage
Supported undercarriage options reduce stress loads and impact forces on undercarriage assemblies and contribute to longer system life.
Load Sensing Hydraulic system improves skidding performance and efficiency.
Load Sensing Hydraulics
Load sensing hydraulics utilize a load sensing, variable displacement pump and pressure compensating system which continually monitors dozer and grapple hydraulic power requirements.Auto-Grab Feature
The Auto-Grab feature from Caterpillar constantly monitors and adjusts tong pressure as needed to securely hold grapple loads while skidding.
Designed operator comfort and ease of operation to ensure maximum productivity.
Easy and Comfortable Operation
Modular ROPS/FOPS cab is resiliently mounted to the frame. Large window area allows excellent front and rear viewing area.Transmission
Power shift transmission delivers three speeds forward and three reverse. Gear selection is quick and easy.Steering
Clutch and brake steering controls each track individually providing exceptional maneuverability.Electronic Monitoring System
Electronic monitoring system monitors critical machine functions and has a three-level warning system to inform operators of potential problems.Blade Control
Single-lever blade control manages all blade functions including height, angle and tilt.Grapple Control
Single-lever grapple control allows for simplified operation and reduced operator fatigue.Auto-Grab Switch
Auto-Grab switch activates the system that monitors and adjusts tong pressure to maintain a secure grip on grapple loads.Seat
Standard suspension seat is angled ten degrees to the right so the operator can more comfortably observe grapple/winch functions to the rear.Air-conditioning
Air-conditioning is standard with the enclosed cab. Controls allow operator to manage cab temperature for optimal comfort levels.Windows
Polycarbonate windows provide excellent viewing and eliminate the need for screens.Canopy
Open ROPS/FOPS canopy is standard with side, front, and rear screens, vandalism protection and optional heater.
The 517 winch is specifically designed for the 517 to help maximize productivity.
The combination of high drawbar pull, torque converter driveline and balance enable the 517 to overcome the loads created during winch applications.Balance and Pulling Power
Superior balance and pulling power enable the 517 to skid large loads with the optional 517 winch. This highly productive winch has been specifically designed for the 517 skidder in steep and mountainous skidding applications.
