John Deere 710B Backhoe Loader Detailed Overview

[MikePhua]

Background & Legacy
The John Deere 710B is a classic backhoe loader model introduced by John Deere Construction. John Deere, founded in 1837, is globally recognized for building reliable agricultural and construction equipment. Over the decades, the 710B became a staple machine for small-to-medium construction, roadwork, and utility jobs, thanks to its balance of power, hydraulics, and maneuverability.

Key Specifications

• Engine:
  • The 710B uses a John Deere 300 Series engine — specifically a 6-cylinder, 5.4 L displacement.
    
  • Turbocharged to provide adequate torque for loader and backhoe operations.
    
  • Net torque is approximately 290 lb-ft (393 N·m).
    
• Hydraulic System:
  • Pump Type: Close‑center (fixed-displacement) hydraulic pump.
    
  • Hydraulic Flow: Around 53 gpm (200 L/min).
    
  • Relief Pressure: Rated for approximately 2,500 psi (17.2 MPa) in many spec sheets.
    
• Operating Weight & Dimensions:
  • Operating Weight (2WD): ~22,500 lb (10,206 kg).
    
  • Tire Pressures (cold inflation):
    • Front: 14.5/75‑16.1 F3, 40 psi (275 kPa)
      
    • Rear: 21L‑24 (various configurations) ~35–40 psi depending on variant
      
  • Transport Length: About 26 ft 8 in (~8.13 m)
    
  • Transport Height: ~13 ft 9 in (~4.20 m)
    
• Capacities:
  • Fuel Tank: ~33 gallons (~125 L) per heavy-spec data.
    
  • Hydraulic Reservoir: ~20 gallons (~75.8 L).
    
  • Cooling System: ~6.9 gallons (~26 L) for radiator / coolant.
    

Strengths and Common Use Cases

• The 710B is known for being versatile: suitable for both loader work (moving dirt, gravel) and backhoe digging/trenching.
  
• Its turbocharged 5.4 L engine gives good low-end torque for lifting and digging.
  
• Because of its hydraulic flow and pressure, it can support reasonably aggressive backhoe operations.
  
• Owners often use it on construction jobs, small excavation sites, and farm works where a compact but capable machine is needed.
  

Common Issues & Maintenance Notes

• Hydraulic Wear: With a hydraulic flow of ~53 gpm, worn hoses or seals can lead to slow or jerky operation. Keep a close eye on hose integrity and replace per signs of wear.
  
• Engine Overhaul: Being an older model, many 710Bs require periodic attention to injection pumps or turbo systems. Operators often report needing to rebuild or replace high-hour engines.
  
• Transmission and Clutch: The powershift (or similar) transmission needs proper maintenance; clutch slippage can become an issue under heavy use.
  
• Hydraulic Overheating: Extended backhoe work can generate heat; proper cooling and correct oil grade are critical.
  

Operational Tips

• Warm-Up: Run the engine a few minutes before using backhoe to allow hydraulic oil to reach operating temperature.
  
• Greasing: Maintain all pivot points (backhoe, loader) regularly to prevent premature wear.
  
• Hydraulic Filters: Change or clean filters on schedule to avoid contamination that could damage pumps or valves.
  
• Tire Pressure: Match tire pressure to the load—correct inflation helps with stability and load lifting.
  

Real-World Feedback & Stories
Several longtime owners note that despite the age of many 710Bs, they remain workhorses because parts like seals, pump kits, and hose assemblies are still widely available thanks to the machine’s popularity. One user shared that he inherited a 710B with over 7,000 hours — a rebuilt swing cylinder and fresh hydraulic lines brought it back to solid operation for many more years.
Reddit users also report issues when pushing hydraulic systems too hard:

“Turning up pressure increases force, but also creates more heat … this extra heat also increases evaporation … it took me a month to find the frame” — a cautionary tale about over-pressurizing hydraulics.

Summary
The John Deere 710B backhoe loader is a solid, dependable machine for users who need a compact but capable loader-digger. While it’s an older design, its engine, hydraulics, and structural durability make it a valuable piece of equipment for construction and farm work. With good maintenance practices — particularly around hydraulics and engine systems — a 710B can remain in productive use for many more years.
