Hydraulic and Control Innovations
The 160X4 incorporates redesigned control spools and Spool Stroke Control (SSC) functions, reducing pressure loss and distributing hydraulic oil more smoothly. This innovation enhances cycle times by up to 5%, improving fuel efficiency and overall productivity. The model is powered by a Final Tier 4 engine, which manages better fuel consumption (approximately 6% improvement) without the need for a Diesel Particulate Filter (DPF), lowering maintenance complexity.
The excavator comes with advanced grade control options through Link-Belt Precision Grade systems. These enable operators of all experience levels to increase productivity by up to 50% by providing real-time bucket positioning relative to the target grade, reducing under or over-excavation on job sites. Two-dimensional (2D) Machine Guidance offers consistent bucket grade and depth control, while 2D Machine Control supports semiautonomous operations where the operator controls the arm only.
Operator Comfort and Maintenance Ease
The cab of the 160X4 is designed with ample legroom and features like a high-back heated seat for prolonged comfort during shifts. Maintenance points are accessible at ground level, facilitating daily upkeep without requiring specialized tools or unsafe access methods.
Undercarriage and Travel System
An X-pattern carbody supports the undercarriage with a long track design for stability. The 160X4 is equipped with sealed and strutted track chains, rollers, and idlers for durability and minimized maintenance. Travel system features include two-speed independent hydrostatic travel with axial piston motors, automatic downshifts for torque, and spring-applied hydraulic release parking brakes integrated into the motors.
Key travel specs:

• Travel Speeds: 1.7 to 3.4 mph (2.8 to 5.4 km/h)
  
• Drawbar Pull: 36,100 lbf (160 kN)
  
• Gradeability: 70% (35 degrees)
  

Attachment Options and Reach
The excavator offers boom length at 16 feet 11 inches (5.15 meters) with available arms:

• 8 feet 7 inches (2.62 meters) arm with 18,800 lbf arm force (power boost available)
  
• 10 feet (3.05 meters) arm with slightly lower arm force
  

Bucket digging forces vary based on arm selection and power boost feature, supporting a wide range of digging and lifting tasks.
Lubricant & Fluid Capacities

• Hydraulic System: 44 gallons (167 liters)
  
• Hydraulic Tank: 22 gallons (82 liters)
  
• Final Drive (per side): 1.5 gallons (5.8 liters)
  
• Swing Drive: 1.3 gallons (4.8 liters)
  
• Engine Oil: 4.5 gallons (17 liters)
  
• DEF Tank: 22 gallons (85 liters)
  
• Coolant System: 4.7 gallons (17.8 liters)
  

Warranty and Support
The 160X4 comes with a substantial 5-year or 5,000-hour full machine warranty, reflecting Link-Belt's confidence in durability. Additionally, RemoteCARE technology offers remote monitoring to track machine location, performance, and maintenance needs, available for desktop and mobile users at no extra cost.
Real-World Usage and Insights
Operators appreciate the 160X4's balance of size and power. The machine's long undercarriage and stable design help counteract front-heavy conditions typically found in machines with extended arms or heavy attachments. For example, operators renting similar-sized equipment have noted the importance of equipped thumbs and wedge-type couplers to improve operational efficiency.
A construction team reported improved project speed and reduced rework after integrating the 2D Machine Guidance system on their 160X4, emphasizing the benefit of modern grade control in preventing costly over-excavation and minimizing physical staking requirements for surveying.
Operator and Buyer Tips

• Confirm that the dealer provides dependable local support since brand dealer stability varies by region.
  
• Consider the upgraded long stick option if working in applications requiring extended reach but balance this with stability concerns.
  
• Utilize the multi-function hydraulic capabilities for attachments, increasing jobsite versatility.
  
• Regularly inspect and maintain the undercarriage components to maximize lifespan, especially the sealed rollers and idlers.
  
• Take advantage of RemoteCARE for predictive maintenance and reduced downtime.
  
• For cold climates, check that block heaters are available or can be added, ensuring smooth start-ups in low temperatures.
