Introduction: Champion Graders and Their Legacy in the Industry
The Champion 720A grader is a versatile and reliable piece of equipment used primarily in road construction, maintenance, and grading projects. Known for its durability, efficiency, and robust performance, the Champion 720A has earned its place in the fleet of many contractors and government agencies around the world. However, like all heavy equipment, the 720A requires proper care and maintenance to continue performing at its best.
In this article, we’ll take a closer look at the Champion 720A grader’s key features, common issues faced by operators, and essential maintenance tips to ensure long-term reliability.
Key Features of the Champion 720A
A construction company working on a major road construction project in a remote area relied heavily on their fleet of Champion 720A graders. In the midst of the project, one of the graders started showing signs of hydraulic system failure, leading to slower blade movement and inconsistent leveling.
The team quickly identified the issue – a hydraulic hose had started to leak fluid, causing a drop in system pressure. After replacing the hose and refilling the hydraulic fluid, the grader was back up and running, demonstrating the importance of proactive maintenance and the ability to diagnose issues quickly.
Conclusion: Keeping the Champion 720A Grader in Peak Condition
The Champion 720A grader is a workhorse in the heavy equipment industry, known for its reliability and versatility. However, like all machines, it requires regular maintenance and troubleshooting to ensure it continues to operate efficiently.
By staying on top of routine maintenance tasks such as fluid checks, air filter replacements, and cooling system inspections, operators can extend the lifespan of their Champion 720A graders and avoid costly repairs. Addressing common issues like hydraulic system failures, transmission problems, and engine overheating early can prevent major downtime, ensuring that the grader remains a valuable asset on the job site.
Through careful attention to detail and proactive maintenance, the Champion 720A can continue to perform at its best for years to come.

- Hydraulic System Failures
One of the common issues faced by operators of the Champion 720A is hydraulic system failures. Since the grader relies heavily on its hydraulics for blade control, issues like leaks, low fluid levels, or malfunctioning hydraulic pumps can significantly affect performance.- Symptoms: Slow blade movement, jerky or unresponsive controls, or visible hydraulic fluid leaks are signs of potential hydraulic system problems.
- Solution: Regularly check hydraulic fluid levels and inspect hoses, pumps, and cylinders for signs of wear or damage. Replacing seals and worn-out components promptly can prevent further issues.
- Symptoms: Slow blade movement, jerky or unresponsive controls, or visible hydraulic fluid leaks are signs of potential hydraulic system problems.
- Transmission Problems
Some operators have reported issues with the transmission in the Champion 720A, especially if the grader has been used heavily or not maintained properly. Transmission problems can lead to difficulties in shifting gears or a loss of power, affecting the grader’s ability to work efficiently.- Symptoms: Slipping gears, delayed response when changing gears, or unusual noises coming from the transmission area could indicate problems.
- Solution: Ensure that the transmission fluid is at the correct level and in good condition. If shifting issues persist, it may be necessary to inspect the transmission for damaged components or leaks.
- Symptoms: Slipping gears, delayed response when changing gears, or unusual noises coming from the transmission area could indicate problems.
- Engine Overheating
Overheating is another concern for the Champion 720A grader, especially when working in hot environments or under heavy loads. This can be caused by low coolant levels, a clogged radiator, or a malfunctioning thermostat.- Symptoms: The engine temperature gauge rising above normal levels, steam or unusual engine smells, or a decrease in engine performance are common indicators.
- Solution: Regularly inspect the cooling system for leaks, ensure the coolant is at the correct level, and clean the radiator and cooling fins to ensure proper airflow.
- Symptoms: The engine temperature gauge rising above normal levels, steam or unusual engine smells, or a decrease in engine performance are common indicators.
- Regular Fluid Checks
One of the most important maintenance tasks for the Champion 720A is keeping all fluid levels topped up and clean. This includes engine oil, hydraulic fluid, transmission fluid, and coolant.- Tip: Create a fluid check schedule based on the manufacturer’s recommendations and environmental conditions. Make sure to use the right types of fluid and replace them as needed.
