• Ground Clearance: Approximately 1.38 feet (420 mm)
  
• Top Speed: About 18.6 mph (30 km/h)
  
• Payload Capacity: Efficient for tasks involving soil, gravel, and medium aggregates
  
• Hydraulic System: Equipped with high-pressure hydraulics for blade lift and tilt control providing strong breakout forces
  

Design and Features
The wheel dozer’s compact size with a wheelbase optimized for balance delivers quick maneuverability on varied terrain. Its all-wheel drive supports good traction in moderate off-road conditions, enhancing productivity in uneven or rocky grounds.
JCB 814 models often feature operator-friendly cabs with good visibility and ergonomic controls, reducing operator fatigue on long shifts. The hydraulic lift systems are designed for responsive blade control, essential in ripping, pushing, and grading work.
Common Applications

• Light to medium earthmoving projects
  
• Road base preparation and grading
  
• Land clearing and debris pushing
  
• Quarry and mining site infrastructure work
  
• Agricultural land reshaping
  

Maintenance and Longevity
The JCB 814 is known for reliable operation but requires regular maintenance including:

• Hydraulic fluid and filter changes to maintain pressure and prevent leakage
  
• Engine servicing consistent with manufacturer schedules to ensure performance and compliance
  
• Inspection and maintenance of wheel and brake systems for safety and durability
  
• Monitoring and upkeep of transmission components to prevent undue wear
  

Terminology

• Wheel Dozer: A type of bulldozer equipped with wheels instead of tracks, designed for faster movement on hard surfaces.
  
• Breakout Force: The hydraulic force exerted to loosen or move material.
  
• Hydrostatic Transmission: Provides variable speed and direction using fluid power.
  
• Operating Weight: The total weight of the machine ready for operation including fluids and standard attachments.
  

Small Story
A construction company in Devon, England, recently restored a vintage JCB 814 wheel dozer for use in land reclamation projects. Despite its age, the machine’s simple, robust design provided reliable performance, and its size allowed it to access narrow rural sites that larger dozers could not. Updates included modern hydraulic components and a refreshed engine, extending its service life and enhancing efficiency.
Summary List

• JCB 814 operating weight ~22,300 lbs with ~100-120 hp engine.
  
• Hydraulic system provides strong blade control and breakout force.
  
• Top speed ~18.6 mph with good all-wheel drive traction.
  
• Versatile for earthmoving, grading, land clearing, and quarry work.
  
• Requires regular maintenance of hydraulics, engine, and drivetrain.
  
• Operator comfort features include ergonomic controls and visibility.
  
• Known for durability and adaptability in varied jobsite conditions.
  

The JCB 814 remains a relevant and capable machine, balancing moderate size with strong performance, ideally suited for operators seeking efficiency in medium-scale construction and earthmoving tasks.
