This article delves into the key features, benefits, and common issues associated with the Bobcat T590, offering troubleshooting tips and maintenance advice to help you keep your machine running smoothly.
Key Features of the Bobcat T590
The Bobcat T590 is part of the Bobcat series of compact track loaders, which are renowned for their rugged performance and efficiency. The T590 model boasts several notable features that make it a top contender in its class.
  1. Engine Power and Performance
    • The Bobcat T590 is equipped with a 74-horsepower Tier 4 diesel engine that provides ample power for demanding tasks like digging, lifting, and pushing. The engine meets the latest emissions standards while offering a balance of fuel efficiency and power.
  2. Hydraulic System
    • With a hydraulic flow of 23.2 gpm (gallons per minute) at 3,500 psi, the T590 is capable of operating heavy-duty attachments, such as augers, grapples, and planers, with ease. The high-flow hydraulic system ensures that the loader can maintain its performance even under high-pressure conditions.
  3. Lift Capacity and Reach
    • The T590 has a rated operating capacity (ROC) of 2,100 lbs and a tipping load of 4,200 lbs, making it suitable for lifting and handling a variety of materials. The vertical lift path ensures that the loader can reach high places and load materials into elevated trucks with minimal effort.
  4. Track System
    • One of the standout features of the Bobcat T590 is its rubber track system, which allows it to perform well on soft or uneven ground. The tracks provide increased traction and stability, allowing the loader to work on challenging surfaces, such as sand, mud, or gravel, without sinking or losing grip.
  5. Operator Comfort and Visibility
    • The T590 features a spacious and ergonomic operator compartment, which includes adjustable seating, user-friendly controls, and improved visibility. The low-profile design of the loader provides excellent sightlines, especially when working in tight spaces or loading materials onto high platforms.
Benefits of the Bobcat T590
The Bobcat T590 is designed to offer several advantages that improve efficiency and productivity on the job site.
  1. Versatility in Various Applications
    • Whether you are lifting heavy materials, digging, grading, or operating specialized attachments, the T590 excels across a wide range of applications. Its ability to switch between different tasks with minimal downtime makes it an ideal choice for contractors, landscapers, and agricultural workers.
  2. Compact Size for Tight Spaces
    • The compact size of the T590 allows it to work in confined spaces where larger equipment might struggle to maneuver. Its tight turning radius makes it an excellent choice for landscaping projects, urban construction sites, and other areas with limited space for heavy machinery.
  3. Fuel Efficiency
    • The fuel-efficient engine combined with the high-flow hydraulic system helps operators save on operating costs. The T590’s engine is optimized to reduce fuel consumption without sacrificing performance, allowing for longer operating hours between refueling.
  4. Low Maintenance Costs
    • Bobcat machines are known for their durability and low maintenance requirements. The T590 is no exception, with easy-to-access components for routine maintenance tasks such as oil changes, air filter replacements, and track adjustments. This helps minimize downtime and maintenance costs.
Common Issues and Troubleshooting Tips for the Bobcat T590
While the Bobcat T590 is a highly reliable machine, like any piece of heavy equipment, it may occasionally experience issues. Below are some common problems faced by operators of the T590, along with troubleshooting tips.
  1. Starting Issues
    • Problem: The T590 may have trouble starting or fail to start altogether. This could be due to a weak battery, faulty ignition switch, or starter motor issues.
    • Solution:
      • Check the Battery: Use a multimeter to check the voltage. A healthy battery should read around 12.6 volts when the engine is off. If the voltage is low, recharge or replace the battery.
      • Inspect the Starter Motor: If the battery is good, but the machine still won’t start, inspect the starter motor for wear or electrical issues.
      • Test the Ignition Switch: A malfunctioning ignition switch can prevent the tractor from starting. Replace the switch if necessary.
  2. Hydraulic System Malfunctions
    • Problem: If the hydraulic system is not operating at full capacity, it could be due to a low fluid level, a clogged filter, or worn hydraulic components.
    • Solution:
      • Check Hydraulic Fluid: Ensure the fluid level is adequate. Low fluid can cause the hydraulic system to fail. Top up the hydraulic fluid as needed, but also check for any leaks in the system.
      • Replace the Hydraulic Filter: A clogged filter can restrict fluid flow and cause the hydraulic system to perform poorly. Replace the filter regularly as part of your maintenance schedule.
      • Inspect Hydraulic Hoses and Fittings: Leaking or damaged hoses can reduce the performance of the hydraulic system. Look for cracks, bulges, or signs of wear.
  3. Track Issues
    • Problem: The tracks of the Bobcat T590 may experience wear, damage, or misalignment over time. This can result in reduced traction, slippage, or uneven wear patterns.
    • Solution:
      • Inspect Track Tension: Check the tension of the tracks regularly. Tracks that are too loose or too tight can cause premature wear or damage to the undercarriage. Adjust the tension as needed according to the manufacturer’s guidelines.
      • Look for Track Damage: Examine the tracks for signs of cracks, tears, or missing lugs. If the tracks are damaged beyond repair, they may need to be replaced.
      • Lubricate the Tracks: Keeping the tracks well-lubricated can reduce friction and prevent wear. Regularly apply a suitable lubricant to the track components.
  4. Electrical Issues
    • Problem: If the T590’s electrical system fails, it may affect the engine, lighting, or hydraulic functions. This could be due to a blown fuse, faulty wiring, or malfunctioning sensors.
    • Solution:
      • Inspect Fuses and Relays: If certain components aren’t working (e.g., lights, dashboard indicators), check the fuses and relays. Replace any that are blown.
      • Check Wiring Connections: Loose or corroded wiring connections can disrupt the electrical system. Inspect the wiring for damage or signs of wear and repair or replace any affected areas.
      • Test Sensors: Malfunctioning sensors can cause incorrect readings or failure of certain functions. Use a diagnostic tool to test the sensors and replace any faulty ones.
  5. Excessive Fuel Consumption
    • Problem: While the T590 is generally fuel-efficient, excessive fuel consumption may occur if the engine is running inefficiently.
    • Solution:
      • Check Air and Fuel Filters: Dirty air or fuel filters can cause the engine to consume more fuel than necessary. Replace the filters regularly to maintain optimal engine performance.
      • Inspect the Fuel Injectors: Clogged or malfunctioning fuel injectors can lead to poor combustion and increased fuel usage. Clean or replace the injectors as needed.
Maintenance Tips to Keep Your Bobcat T590 Running Smoothly
  1. Perform Regular Oil Changes: Regular oil changes are crucial to maintaining engine performance. Change the engine oil and filters at recommended intervals, typically every 250-500 hours of operation.
  2. Keep the Radiator Clean: Dust and debris can accumulate on the radiator, reducing its efficiency. Clean the radiator regularly to prevent overheating and ensure optimal engine cooling.
  3. Check and Replace the Air Filters: Dirty air filters can reduce engine efficiency and increase fuel consumption. Inspect and replace the air filter regularly to keep the engine breathing clean air.
  4. Track and Undercarriage Maintenance: Regularly inspect the tracks and undercarriage for wear or damage. Proper track tension and regular lubrication can significantly extend the lifespan of the tracks.
  5. Monitor Hydraulic System Performance: Regularly check the hydraulic fluid levels and inspect the hydraulic hoses for leaks. Clean or replace filters as needed.
Conclusion
The Bobcat T590 is a powerful, efficient, and versatile compact track loader that excels in various tasks. While it is a reliable machine, operators may occasionally encounter issues related to the engine, hydraulics, tracks, or electrical system. By performing regular maintenance and keeping an eye out for common problems, you can ensure that your Bobcat T590 continues to perform at its best and serves you well for many years.
With proper care, the T590 can help you maximize productivity on the job site, tackle a wide range of tasks, and operate efficiently in various conditions.
