Machine Background and Performance
The Bobcat S650 skid-steer loader is part of the 600 frame size series, designed to deliver a balance of power, lift capacity, and maneuverability for diverse construction, landscaping, and material handling applications. It features a vertical lift path, ideal for tasks requiring greater forward reach at full lift height, such as truck loading and pallet handling.
Engine and Power

• Powered by a 74 horsepower turbocharged Tier 4 diesel engine.
  
• The engine design focuses on providing more usable horsepower while complying with emissions regulations, utilizing technologies that avoid the need for diesel particulate filters, reducing downtime.
  
• Fuel tank capacity is 23.9 gallons, supporting extended operational time.
  

Hydraulic and Lift System

• Equipped with high-flow auxiliary hydraulics delivering 23 gallons per minute standard flow with an optional high-flow system available.
  
• System relief pressure near 3500 psi ensures sufficient force for heavy attachment operation.
  
• The vertical lift path mechanism provides smooth and stable lifting with reduced side-to-side arm movement, enhancing operator control and reducing wear on pins and bushings.
  

Operating Dimensions and Capacities

• Operating weight is approximately 8,061 lbs.
  
• Rated operating capacity stands at 2,690 lbs per ISO standards, with a tipping load of around 5,380 lbs.
  
• The machine measures about 136.8 inches in length with the bucket, 72 inches in width, and 81.3 inches in height to the top of the cab.
  
• Height to hinge pin is 124 inches, allowing for significant dumping clearances.
  
• Maximum reach at full height is 31.5 inches, facilitating efficient loading.
  

Maneuverability and Controls

• Turning radius approximately 82.9 inches, allowing navigation in tight workspaces.
  
• Travel speed ranges up to 7.1 mph with a two-speed transmission option increasing speed to 12.3 mph.
  
• Hydrostatic transmission provides smooth directional and speed changes without clutching.
  
• Ergonomic controls with optional joystick enhance operator comfort and precision.
  
• The Bob-Dock attachment system enables quick attachment swaps without leaving the cab.
  

Operator Comfort and Safety

• The enclosed cab offers options for heating, air conditioning, sound suppression, and suspension seat.
  
• Visibility is improved through design features like top and rear windows and optional rearview cameras.
  
• Safety interlocks and BICS (Bobcat Interlock Control System) prevent unintended machine operations.
  
• Parking brakes, backup alarms, and standard lighting enhance site safety.
  

Applications

• Suitable for construction sites, agriculture, landscaping, and general material handling jobs.
  
• The S650 handles a broad spectrum of attachments—buckets, forks, augers, breakers—making it adaptable to various tasks.
  
• Its compact size and powerful lift make it ideal for sites with limited space and demanding lift needs.
  

Glossary of Terms

• Vertical Lift Path: Lift design that moves the loader arms in a vertical arc for better reach and stability at full height.
  
• High-Flow Hydraulics: Hydraulic system providing increased flow for more powerful attachment operation.
  
• Bob-Dock: Quick-attachment mounting system improving attachment change efficiency.
  
• Tipping Load: Weight at which the machine is likely to tip forward when the load is raised.
  
• BICS: Safety system preventing unintended activation of controls.
  

Conclusion
The Bobcat S650 skid-steer loader combines robust power, versatile hydraulics, and enhanced operator comfort to deliver a machine adept at handling challenging tasks efficiently. Its vertical lift path, high lift capacity, and precise controls make it a versatile asset in various industries. Safety features and cab comforts complement its performance, providing a reliable and operator-friendly machine suitable for a wide range of demanding applications.
