The Bobcat 743 is a widely recognized skid steer loader, known for its versatility, durability, and ease of use in various construction, landscaping, and agricultural tasks. This machine has built a solid reputation over its years of production, being a popular choice for operators who require a reliable compact loader capable of handling a broad range of jobs.
History and Development of the Bobcat 743
Bobcat, a company founded in 1947, revolutionized the compact loader industry with the introduction of its first skid-steer loader in 1958. The Bobcat 743 was part of this long lineage of innovation, first produced in the late 1980s. Its development was centered around the need for a more powerful yet compact machine that could operate efficiently in tight spaces, offering performance and stability that traditional larger machines couldn’t match. The 743 model was designed to meet the demands of contractors, landscapers, and farmers alike, all while maintaining ease of operation and low maintenance costs.
Bobcat’s success with the 743 has been due to its proven reliability in harsh environments and its adaptability to various job sites. Its relatively small frame, combined with its powerful engine, made it a popular choice for jobs ranging from site preparation to snow removal. The 743 quickly became one of the most popular skid steer models in the Bobcat lineup.
Key Features of the Bobcat 743

1. Engine and Power: The Bobcat 743 is equipped with a 45 horsepower (HP) diesel engine, offering solid power to handle heavy lifting, digging, and pushing tasks. The machine’s engine, typically a 4-cylinder, is designed for durability and efficiency, ensuring it can perform under various work conditions. Operators can expect a reliable and consistent power output, making the Bobcat 743 suitable for both light and moderately heavy-duty tasks.
   
2. Hydraulics and Lift Capacity: One of the standout features of the Bobcat 743 is its hydraulic system. The machine comes with a powerful auxiliary hydraulic system capable of powering numerous attachments. The standard lift capacity of the 743 is around 1,300 pounds (590 kg), making it well-suited for a wide range of lifting tasks, from moving materials to lifting heavy pallets or containers.
   
3. Compact Size and Maneuverability: The Bobcat 743's compact size allows it to operate in tight spaces that would typically be inaccessible to larger machines. Its width of approximately 56 inches (142 cm) allows for easy maneuverability in crowded job sites or narrow pathways, making it a go-to tool for landscapers, urban construction, and small-scale contractors.
   
4. Attachment Versatility: Like many other Bobcat skid steers, the 743 is known for its wide compatibility with various attachments. Whether it’s a bucket, auger, grapple, snowblower, or pallet fork, the 743’s auxiliary hydraulic system allows operators to switch between tasks quickly and efficiently, adding to the machine’s versatility.
   
5. Operator Comfort and Safety: The Bobcat 743 offers a simple, user-friendly control panel and clear visibility from the operator’s seat. The design of the cab, while functional and straightforward, also ensures that the operator has ample space and comfort during long working hours. Safety features such as the roll-over protection system (ROPS) and standard seatbelt further enhance the operator's well-being.
   

Common Issues with the Bobcat 743
While the Bobcat 743 is a robust and reliable machine, like any piece of heavy equipment, it is not immune to common wear-and-tear issues. Below are a few problems that operators and owners of Bobcat 743 loaders may encounter:

1. Hydraulic System Failures: One of the more frequent issues reported with the Bobcat 743 is hydraulic system failure. Problems such as slow movement or lack of response from the loader’s arms are often traced back to issues with the hydraulic pump, hoses, or fluid levels. Regular maintenance and timely fluid changes are crucial to keeping the hydraulic system running smoothly.
   
2. Drive Motor Problems: The Bobcat 743 can sometimes experience problems with its drive motors, which can result in loss of power or poor traction. A failing drive motor can lead to the loader becoming sluggish or even immobilized. Replacing worn-out motors or addressing leaks promptly is important for ensuring consistent performance.
   
3. Electrical Failures: Some owners have reported issues with the electrical system, particularly with fuses and battery connections. Electrical failures can cause the loader to not start or have erratic behavior while operating. Ensuring that the battery is properly maintained and that electrical connections are tight and free of corrosion can prevent many of these issues.
   
4. Worn Tires and Tracks: As with any skid steer, the Bobcat 743's tires or tracks can wear down with extensive use. Since the 743 operates in challenging conditions, ensuring that the wheels or tracks are in good condition is essential for maintaining stability and traction. Worn-out tires can cause the loader to struggle with pushing and lifting, while tracks may become loose or damaged over time.
   
5. Cooling System Overheating: Some owners of the Bobcat 743 have noticed the engine may overheat during intense operations, especially when working in hot weather or during long hours of use. Regular maintenance and cleaning of the radiator and cooling fan can help prevent this issue and ensure the machine maintains optimal operating temperatures.
   

Maintenance and Care
Routine maintenance is key to extending the lifespan and performance of the Bobcat 743. Some of the most critical maintenance tasks include:

• Hydraulic Fluid Checks: Regularly checking the hydraulic fluid levels and replacing them as recommended by the manufacturer ensures optimal performance. Hydraulic fluid that is too low or contaminated can affect the system’s responsiveness and lift capacity.
  
• Greasing and Lubrication: Regular greasing of the machine’s moving parts, including the loader arms and pivot points, will minimize friction and wear, ensuring smooth operations.
  
• Tire or Track Inspections: The tires or tracks should be regularly inspected for wear, proper inflation (for tires), and damage. Replacing worn tires or adjusting tracks before they become severely damaged can save on expensive repairs.
  
• Air Filter and Engine Checks: The engine air filter should be inspected and replaced when needed to avoid clogging. Regular engine oil and filter changes are essential to keeping the engine running smoothly.
  

Conclusion
The Bobcat 743 remains a solid choice for anyone in need of a compact, durable, and versatile skid steer. While it comes with its share of common issues, the benefits of owning a Bobcat 743 far outweigh the challenges, particularly when proper maintenance and care are observed. Whether you are using it for landscaping, construction, or general material handling, the 743 offers the power, agility, and attachment compatibility necessary for getting the job done efficiently. By taking care of its maintenance needs and addressing issues promptly, operators can ensure the Bobcat 743 continues to deliver reliable performance for years to come.
