Evaluating a Bobcat 853 Purchase: Mechanical Potential and Project Viability
#1
Introduction to the Bobcat 853 Skid Steer
The Bobcat 853 is a mid-sized skid steer loader produced in the late 1980s and early 1990s. Known for its robust frame, reliable diesel engine, and straightforward hydraulic system, it remains a popular choice among DIY mechanics and small contractors. With an operating capacity of around 1,700 lbs and a 60-horsepower engine, the 853 offers solid performance for grading, lifting, and light excavation tasks.
Terminology Clarification
  • Skid Steer Loader: A compact, maneuverable machine with lift arms used for various attachments.
  • Hydraulic Cylinder: A mechanical actuator that converts hydraulic energy into linear motion, used to lift or tilt the loader arms or bucket.
  • Engine Cylinder: A combustion chamber within the engine block where fuel is ignited to produce power.
  • Operating Hours: The total time the machine has been in use, often tracked via an hour meter.
  • Project Loader: A machine purchased with the intent to repair or restore before use or resale.
The Offer: $4,000 for a Running Bobcat 853
The machine in question was offered for $4,000, reportedly running but requiring a cylinder replacement. With approximately 2,500 hours on the meter, it presents as a potential winter project for a diesel mechanic. The buyer already owns a Bobcat 753, suggesting familiarity with the platform and parts interchangeability.
Assessing the Cylinder Issue
The term “cylinder” can refer to either a hydraulic or engine component. In this case, the ambiguity prompted discussion:
  • Hydraulic Cylinder Replacement
    Typically involves removing the damaged cylinder, sourcing a replacement or rebuild kit, and reinstalling. This can be completed in a weekend with basic tools.
  • Engine Cylinder Repair
    More complex, requiring disassembly of the engine head, piston inspection, and possibly machining. This would extend the project timeline and increase costs.
Given the machine runs, the issue likely pertains to a hydraulic cylinder—possibly a lift or tilt cylinder—making the repair more manageable.
Field Anecdote: The Winter Project Tradition
In rural Ohio, a diesel mechanic purchased a non-running Bobcat 843 for $3,200. Over the winter, he rebuilt the lift cylinders, replaced hoses, and installed new tires. By spring, the machine was operational and sold for $8,500. The project not only yielded profit but also served as a bonding experience with his teenage son, who learned basic hydraulics and welding.
Market Value and Regional Variability
Operators noted that in some regions, a running Bobcat 853—even with minor issues—is worth more than $4,000. In Western Washington, for example, similar machines fetch $6,000–$8,000 depending on condition. Even non-running units with intact frames and engines are considered valuable for parts or restoration.
Best Practices for Evaluating Used Equipment
  • Inspect frame welds and loader arm bushings
  • Check hydraulic hoses for cracks or leaks
  • Test engine compression and listen for knocking
  • Verify hour meter accuracy and look for signs of tampering
  • Examine tires or tracks for wear and dry rot
  • Confirm availability of parts through local dealers or salvage yards
Tips for Project Success
  • Set a realistic budget for parts and tools
  • Allocate time for troubleshooting and unexpected delays
  • Document repairs for future resale or maintenance
  • Use OEM or high-quality aftermarket components
  • Consult service manuals and online communities for guidance
Conclusion
Purchasing a Bobcat 853 for $4,000 with a known cylinder issue can be a worthwhile investment—especially for a skilled mechanic seeking a winter project. With manageable repairs and a solid resale market, the machine offers both utility and learning opportunities. As with any used equipment, success depends on careful inspection, realistic expectations, and a willingness to get your hands dirty. In the world of iron and hydraulics, sometimes the best deals come wrapped in grease and potential.
