Common Bobcat T300 Problems and Fixes

1. Hydraulic Issues

Symptoms: Sluggish movement, slow lift/lower of the boom, weak attachment performance.

Cause: Could be due to low hydraulic fluid, clogged filters, or worn-out hydraulic pumps.

Fix:

  • Check and refill hydraulic fluid.
  • Replace the hydraulic filter.
  • Inspect pump and hoses for wear and leaks.

2. Overheating Engine

Symptoms: Engine warning lights, power loss, high temperature readings.

Cause: Clogged radiator, failed thermostat, or worn water pump.

Fix:

  • Blow out debris from the radiator and oil cooler.
  • Replace thermostat and inspect coolant levels.
  • Consider upgrading to a higher-performance cooling fan if operating in hot/dusty environments.

3. Drive Motor Failure

Symptoms: Loss of movement on one side, grinding noises, leaks.

Cause: Internal motor wear or seal failure.

Fix:

  • Inspect the final drive motor for damage or leakage.
  • Replace seals or rebuild the motor.
  • Always maintain proper fluid levels to avoid premature failure.

4. Electrical Problems

Symptoms: Non-functioning dash, starter won’t crank, dead battery.

Cause: Loose connections, corrosion, or worn alternator.

Fix:

  • Check and clean battery terminals.
  • Inspect ground connections and replace damaged wires.
  • Test alternator and replace if voltage output is below spec.

5. Track and Undercarriage Wear

Symptoms: Uneven ride, track slipping or derailing, excessive vibration.

Cause: Worn sprockets, misaligned tensioners, or damaged rollers/idlers.

Fix:

  • Regularly inspect and adjust track tension.
  • Replace worn sprockets and rollers.
  • Lubricate and clean the undercarriage after each use.

6. Glow Plug and Starting Issues in Cold Weather

Symptoms: Difficulty starting in cold temperatures.

Cause: Faulty glow plugs, weak battery, or outdated block heater.

Fix:

  • Test and replace faulty glow plugs.
  • Install a modern block heater.
  • Use a battery with higher cold cranking amps (CCA).

7. Hydraulic Cylinder Leaks

Symptoms: Oil dripping from boom or bucket cylinders.

Cause: Worn or damaged cylinder seals.

Fix:

  • Replace cylinder seals.
  • Inspect cylinder rods for scoring or bends.
  • Avoid overloading attachments to extend seal life.

Maintenance Tips for Long-Term Reliability

  1. Perform Regular Fluid Checks: Hydraulic, engine oil, coolant, and fuel filters should be checked and replaced according to Bobcat’s maintenance schedule.
  2. Keep the Radiator Clean: Especially in dusty environments—use compressed air or a soft brush.
  3. Track Tensioning: Overly tight tracks can wear out the undercarriage; loose tracks can derail. Adjust tension per manufacturer specs.
  4. Battery Maintenance: Clean terminals, check fluid levels (if applicable), and ensure proper voltage.
  5. Inspect for Leaks Frequently: Catching a small hydraulic or fuel leak early can prevent major repairs later.
  6. Daily Greasing: Proper lubrication of the pivot pins, arms, and loader frame is essential.
  7. Store in Covered Area: Helps protect electronics and hydraulic systems from moisture damage.

Performance Notes

  • The T300 delivers excellent pushing power and lifting performance, ideal for land clearing, grading, and construction.
  • With the optional high-flow hydraulics, it’s capable of running powerful attachments like stump grinders, trenchers, and cold planers.
  • Operator visibility is above average, but upgrading to LED work lights significantly improves nighttime operation.

Attachments That Work Well with T300

  • Forestry Mulcher
  • Auger Drive
  • Snow Blower
  • Grapple Bucket
  • 4-in-1 Bucket
  • Brush Cutter

Always match the attachment’s flow requirements with the T300’s hydraulic specs to avoid overloading the system.

Should You Buy a Used Bobcat T300?

Pros:

  • High lifting capacity and reliable Kubota engine.
  • Wide availability of parts.
  • Excellent for heavy-duty work.

Cons:

  • Some units show age with undercarriage wear.
  • May require updates to electronics or controls.

Buying Tips:

  • Check service history.
  • Test drive for drive motor noises or performance drops.
  • Inspect the boom and tilt cylinders for leaks.

Final Thoughts

The Bobcat T300 remains a formidable compact track loader, even years after its initial release. While there are common issues to watch for—especially in high-hour machines—many can be fixed affordably with proper maintenance.

For contractors who need a powerful and versatile loader without breaking the bank, the T300 continues to be a viable choice in the used equipment market.
