1. Common Issues with the Bobcat 753 Skid Steer
The Bobcat 753 is a robust and widely-used piece of equipment, but like any other machine, it can experience issues that require attention. Some of the most frequently reported problems include:
- Hydraulic System Problems
- Engine Issues
- Electrical Failures
- Transmission and Drive Problems
2. Hydraulic System Problems
The Bobcat 753, like many skid steers, uses hydraulic power to operate attachments and perform various tasks. When issues arise within the hydraulic system, it can cause a range of problems, including slow or unresponsive bucket movements, or even complete failure to lift and operate attachments.
2.1. Low Hydraulic Pressure
Low hydraulic pressure is a common issue and can be caused by several factors:
- Dirty Hydraulic Fluid: Over time, hydraulic fluid can accumulate contaminants and lose its viscosity, leading to inefficient system performance. Ensure the hydraulic fluid is clean and topped up to the appropriate level.
- Faulty Hydraulic Pump: A worn or malfunctioning hydraulic pump can fail to provide the necessary pressure, leading to sluggish operation. Regular inspection and testing of the pump can help catch issues early.
- Leaking Hydraulic Hoses: Leaks in the hoses or fittings can result in a drop in hydraulic pressure. Inspect hoses for signs of wear, abrasions, or cracks, and replace them as needed.
Another common complaint is slow lift operation or failure to raise attachments properly. This could be due to:
- Air in the Hydraulic Lines: Air bubbles in the hydraulic lines can cause inconsistent or sluggish lift performance. Bleeding the hydraulic lines can often resolve this issue.
- Faulty Lift Cylinders: If the lift cylinders are damaged or leaking, it can prevent the bucket or arms from lifting to full height. Check for visible damage or leaks and replace any damaged parts.
The engine is the heart of any skid steer, and problems with it can range from hard starting to complete failure to start. Some of the most common engine-related issues include:
3.1. Engine Won’t Start
If your Bobcat 753 is having trouble starting, check the following:
- Battery Charge: The most common culprit for a no-start situation is a dead or weak battery. Inspect the battery and cables for corrosion or loose connections. A fully charged battery is essential for engine ignition.
- Fuel System Blockages: Dirty fuel filters or clogged fuel lines can prevent the engine from receiving the proper amount of fuel. Make sure to replace the fuel filter regularly and check for any blockages.
- Ignition System Failure: Faulty spark plugs or ignition components can also prevent the engine from starting. Ensure that spark plugs are clean and in good condition, and replace them if needed.
Overheating can cause severe engine damage if not addressed promptly. Potential causes of overheating include:
- Low Coolant Levels: Ensure that the coolant is at the proper level. If low, check for leaks in the radiator, hoses, or coolant reservoir.
- Clogged Radiator: Dirt and debris can accumulate on the radiator fins, obstructing airflow and reducing the radiator’s efficiency. Regular cleaning of the radiator can help prevent this.
- Faulty Thermostat: A malfunctioning thermostat can cause the engine to overheat by failing to regulate coolant flow. Replacing a faulty thermostat is a relatively simple fix.
Electrical issues can be frustrating, as they are often difficult to diagnose without the right tools. Common electrical problems on the Bobcat 753 include:
4.1. Blown Fuses
Blown fuses are a common issue that can cause the instrument panel or certain functions of the machine to stop working. Check the fuse panel for any blown fuses and replace them with new ones of the correct rating.

The Bobcat 753 uses a hydrostatic transmission system, which allows smooth operation and control of the skid steer. Common transmission and drive issues include:
5.1. Loss of Power to the Wheels
Loss of power to the wheels, or difficulty in moving the skid steer, is often related to the hydrostatic transmission system. This could be caused by:
- Low Transmission Fluid: Ensure the fluid level is correct, as low levels can cause slipping or poor performance.
- Clogged Transmission Filter: The transmission filter can become clogged over time, restricting fluid flow and causing the transmission to fail. Regular replacement of the filter can help prevent this issue.
- Worn Drive Motors or Pumps: If the drive motors or hydraulic pumps are worn out, the machine may struggle to move or lose power during operation. These components may need to be replaced if they are beyond repair.
To minimize downtime and ensure that your Bobcat 753 operates at peak efficiency, regular maintenance is essential. Here are a few tips to keep your skid steer in top condition:
- Regular Fluid Checks: Check and replace hydraulic fluid, engine oil, and coolant regularly. Keeping the fluid at the correct levels and using high-quality fluids will help protect the machine’s components.
- Air Filter Maintenance: Clean or replace the air filter regularly to ensure that the engine receives the necessary airflow for combustion.
- Greasing the Machine: Grease all moving parts, including the loader arms, bucket pivots, and wheels, to ensure smooth operation and reduce wear.
- Inspect Tires and Tracks: Inspect the tires or tracks regularly for signs of wear or damage. Properly inflated tires or well-maintained tracks are critical for efficient performance.
The Bobcat 753 is a powerful and reliable skid steer loader, but like all machinery, it requires regular maintenance and timely troubleshooting to operate efficiently. By understanding common issues and performing routine maintenance, you can prolong the lifespan of your equipment, reduce downtime, and keep your machine in optimal working condition.
