Built for a variety of tasks, the Kubota 35ZTS is equipped with a powerful engine, high-flow hydraulics, and robust digging capabilities. Despite its compact size, the 35ZTS can handle a range of heavy-duty applications, making it a valuable asset for contractors who need a reliable, powerful machine for smaller spaces.
Key Features of the Kubota 35ZTS

1. Zero Tail Swing Design
   The primary feature of the Kubota 35ZTS is its zero tail swing (ZTS) design. This means that the machine’s tail does not extend beyond the width of the tracks, providing better safety and maneuverability in tight spaces. The ZTS design ensures that the operator has a clear view of the surroundings, reducing the risk of damaging property or injuring bystanders.
   
2. Compact Size and Versatility
   The compact dimensions of the 35ZTS allow for easy transport and operation in confined areas. With an operating weight of approximately 3,800 kg (8,400 lbs), it can fit on a standard flatbed truck, making it easy to move between job sites. The compact size doesn’t mean a reduction in performance, though—the 35ZTS can still achieve impressive digging depth and reach for tasks like trenching, lifting, and grading.
   
3. Powerful Engine Performance
   Powered by a 24.8-horsepower Kubota engine, the 35ZTS delivers impressive power and efficiency for its size. The engine’s smooth performance ensures that the excavator can handle tough conditions while keeping fuel consumption to a minimum. The engine is also designed to be low-maintenance and durable, reducing the total cost of ownership.
   
4. Advanced Hydraulic System
   The Kubota 35ZTS features an advanced hydraulic system, which provides high-flow capabilities for faster operation. The system offers smooth and responsive control, ensuring that the excavator can perform a range of tasks efficiently. The hydraulic performance is further enhanced by the machine’s advanced boom and arm design, which increases lifting and digging capacity.
   
5. Operator Comfort
   The operator’s comfort and ease of use are prioritized with the Kubota 35ZTS. The operator’s station is designed with a fully adjustable seat, intuitive controls, and clear visibility from the cab. The design helps reduce operator fatigue during long shifts, improving overall productivity.

Common Issues and Troubleshooting Tips
Like all construction equipment, the Kubota 35ZTS may face occasional issues, particularly as it accumulates hours of use. Here are some common issues and troubleshooting tips:

1. Hydraulic System Issues
   If the hydraulic system isn’t performing optimally, it could be due to low fluid levels, air in the system, or contamination in the hydraulic fluid. These issues can cause reduced digging force, slow operation, or erratic control responses.
   • Solution: Check hydraulic fluid levels regularly and replace fluid if it appears dirty or contaminated. Inspect hoses, valves, and cylinders for leaks. If there’s air in the hydraulic system, bleed the system to restore normal operation.
     
2. Engine Power Loss
   A loss of engine power may result in sluggish operation or difficulty completing tasks. Common causes include clogged air filters, dirty fuel injectors, or a malfunctioning fuel pump.
   • Solution: Inspect and replace the air filter if necessary. Clean the fuel injectors and replace the fuel filter if it’s clogged. Ensure the fuel system is functioning properly by checking the fuel lines and fuel pump.
     
3. Track Wear or Damage
   Due to the frequent contact with dirt, gravel, and other materials, the tracks on the Kubota 35ZTS can wear over time. If the tracks become damaged, it may affect the machine’s mobility and stability.
   • Solution: Regularly check the condition of the tracks. If they are worn or damaged, replace them promptly. Also, inspect the track tension and adjust it to ensure proper track alignment and tension.
     
4. Electrical Issues
   Electrical issues can arise from faulty wiring, a dead battery, or malfunctioning sensors. These issues may result in the machine not starting or operational errors.
   • Solution: Inspect the wiring for any visible signs of damage. Test the battery voltage and replace the battery if it is weak or dead. If sensors are malfunctioning, check for any error codes using a diagnostic tool and replace any faulty components.
     

Maintenance Tips for the Kubota 35ZTS
To keep the Kubota 35ZTS in optimal working condition, regular maintenance is essential. Here are some key maintenance tasks to follow:

• Hydraulic Fluid and Filter Change: Change the hydraulic fluid and filters at regular intervals to prevent contamination and maintain the efficiency of the hydraulic system.
  
• Track Inspection and Maintenance: Regularly inspect the tracks for wear, damage, and tension. Lubricate the track rollers and adjust track tension as needed.
  
• Engine Maintenance: Perform routine engine checks, including replacing the air filter, fuel filter, and oil. Clean or replace the radiator as needed to prevent overheating.
  
• Grease Points: Lubricate all moving parts, such as joints, pins, and bearings, to reduce wear and prevent premature failure.
