Bobcat 825 Skid Steer Loader: An In-Depth Guide to Specifications, Parts, Maintenance, and Practical Advice
#1
Introduction to the Bobcat 825 Skid Steer Loader
The Bobcat 825 is a classic skid steer loader known for its robust design, moderate power output, and versatility on various job sites. As a key machine from Bobcat’s line of loaders, the 825 model is widely used in construction, landscaping, agriculture, and material handling tasks. Understanding its key features, available parts, maintenance requirements, and common upgrades can help owners and operators enhance productivity and extend machine life.
Core Specifications of the Bobcat 825
  • Engine and Power: The Bobcat 825 is powered by a reliable diesel engine delivering approximately 38 to 42 horsepower. This engine is typically liquid-cooled (not turbocharged) and designed for durability in rugged environments.
  • Operating Weight: Around 5,780 lbs, providing a stable platform for various attachments and loads.
  • Rated Operating Capacity: Approximately 1,500 lbs, which refers to the safe lifting capacity per SAE standards.
  • Tipping Load: About 3,100 lbs, indicating the maximum tipping point when lifting a load.
  • Dimensions:
    • Length: Approximately 125 inches (about 10.4 feet)
    • Width: Around 61 inches (about 5 feet)
    • Height: Roughly 85 inches (7 feet) to the operator cab or top of machine
  • Auxiliary Hydraulic Flow: Available on an optional basis, high flow auxiliary hydraulics deliver about 12.5 gallons per minute, enabling the use of hydraulic-powered attachments.
  • Controls and Features: The Bob-tach® attachment system is standard, providing quick attachment changes. Optional equipment includes operating lights and auxiliary hydraulics, though advanced features such as air conditioning or deluxe instrumentation are not standard on this model.
Parts and Common Components
Owners looking for Bobcat 825 parts need to focus on several key categories:
  • Engine Components: Fuel filters, air filters, injectors, and cooling system parts are essential for sustained engine performance.
  • Hydraulic System Parts: Hoses, pumps, cylinders, and optional high-flow components require regular inspection and replacement to avoid leaks and maintain power delivery.
  • Undercarriage and Tires: While the 825 is wheeled, tire condition affects stability and traction—replacement tires or tubes should match original size specifications.
  • Drive and Transmission Parts: Drive belts, wheel bearings, seals, and linkage components wear over time and need timely attention.
  • Attachment Interface: Bob-tach components, pins, bushings, and locking mechanisms must remain robust to safely handle frequent attachment changes.
Maintenance Considerations and Solutions
  • Regular Inspections: Daily or pre-shift checks on fluid levels, leaks, tire integrity, and attachment security minimize unexpected breakdowns.
  • Lubrication: Greasing pivot points, lift arms, and attachment pins reduces wear and extends component life.
  • Hydraulic Oil and Filters: Maintain clean hydraulic fluid and timely replacement of filters to sustain performance, particularly important if using a high-flow hydraulic system.
  • Engine Fluids: Routine oil changes, coolant checks, and fuel system maintenance are critical for reliable engine operation.
  • Electrical System Care: Inspect wiring, battery terminals, and switchgear periodically to prevent electrical faults.
  • Operator Training: Skilled handling reduces undue stress on the machine, especially during loading and maneuvering.
Practical Tips and Upgrade Recommendations
  • Attachment Compatibility: The Bob-tach system accommodates a wide range of attachments such as buckets, pallet forks, hydraulic augers, trenchers, sweepers, and brush cutters. Investing in quality attachments enhances machine utility.
  • High-Flow Hydraulic Kits: Upgrading to or maintaining a high-flow auxiliary system expands attachment options, enabling more powerful tools like hydraulic breakers or stump grinders.
  • Tire Choices: Selecting tires appropriate for the terrain (e.g., turf tires for grass, lugged tires for rough ground) improves traction and reduces wear.
  • Parts Sourcing: Using OEM or certified aftermarket parts ensures fit, durability, and safety compliance. Trusted suppliers often stock critical parts such as hydraulic pumps, seals, control arms, and engine components.
  • Storage and Pre-Season Checks: Proper winterization, cleaning, and storage procedures protect machine components during off-season periods and prepare the loader for peak performance upon return to work.
Case Examples and Operator Stories
A landscaping company operating Bobcat 825 loaders reported that regular hydraulic system maintenance and using genuine parts helped prevent frequent downtime during peak seasons. They found that the quick attachment changes via Bob-tach saved significant time on job transitions, improving daily productivity.
In a small farm application, a Bobcat 825 equipped with a grappling bucket and auger helped efficiently clear fence lines and post holes. The operator emphasized the importance of pre-shift inspections and timely replacement of worn hoses to avoid costly hydraulic failures in remote locations.
Glossary of Key Terms
  • Rated Operating Capacity (ROC): Maximum load the machine can safely lift according to SAE standards.
  • Tipping Load: The threshold weight at which the loader may tip over when lifting a load.
  • Bob-tach® Attachment System: A quick-attachment system designed by Bobcat for fast and secure mounting of accessories.
  • Hydraulic Auxiliary Flow: Hydraulic fluid volume available to power attachments, typically measured in gallons per minute (gpm).
  • High-Flow Hydraulic System: An enhanced hydraulic circuit providing increased flow for more powerful attachments.
  • OEM (Original Equipment Manufacturer): Original parts produced by the machinery maker, ensuring proper fit and function.
Summary and Recommendations
The Bobcat 825 skid steer loader balances reliable diesel power, moderate lifting capacity, and compatibility with diverse attachments, making it a versatile choice for many industries. Proper maintenance focusing on hydraulics, engine care, and undercarriage components is vital to keep this machine performing efficiently.
Owners should prioritize sourcing quality parts, especially hydraulic components and engine filters, and invest in operator training to maximize machine lifespan and safety. Upgrading auxiliary hydraulics where feasible can expand functionality and machine versatility.
By incorporating these best practices and understanding the machine’s technical specifications and parts needs, Bobcat 825 owners can ensure dependable service and optimal performance across a wide range of job types and environments. This approach supports long-term operational success and cost-effective equipment management.
