[MikePhua]

A 1993 John Deere 310D backhoe loader is more than just a machine—it reflects a period in construction history when versatility and durability blended in a mid-size powerhouse. Equipped with dependable mechanics and built by an industry stalwart, this model remains a sought-after workhorse decades later.
Development background
John Deere introduced the 310D in the early 1990s, succeeding the 310C and preceding the 310E line—part of its D-series models designed for utility construction and agricultural tasks . Manufactured between approximately 1990 and 1998, the 310D embodied Deere’s move toward more efficient hydraulics and operator comforts .
Company snapshot
Deere & Company, known widely as John Deere, is a U.S.-based global machinery manufacturer founded in 1837 . By 2024, it ranked among the largest agricultural and heavy-equipment producers in the world, with diverse product lines spanning tractors, backhoes, harvesters, and even advanced robotics . The 310D reflects its mid-late-20th-century dedication to multi-purpose machines.
Technical profile of the 1993 310D
From verified specifications, the 1993 model typically featured:

• Engine: John Deere 4039D 4-cylinder diesel, delivering around 70 hp net (though some sources list gross power up to 74 hp) .
  
• Digging performance: Backhoe dig depth up to approximately 15 ft (standard) and potentially 18 ft when extended; bucket dig force around 11,570 lb .
  
• Loader lift: Breakout force near 9,350 lb, with bucket capacity near 1 cubic yard and width around 92 inches .
  
• Hydraulic system: Open-center pump flow about 38 gpm; system pressure near 2,700 psi .
  
• Capacities:
  • Fuel tank ~34 gal
    
  • Hydraulic fluid ~21 gal
    
  • Cooling system ~4 gal .
    
• Weight and dimensions:
  • Operating weight between 13,600 and 14,290 lb
    
  • Transport length ~23 ft, width ~7 ft, height to cab ~9 ft, wheelbase around 83 inches (approx. 7 ft) .
    
• Powertrain: 4-speed shuttle-shift or power shuttle transmission; available in 2-wheel or 4-wheel drive; power steering with hydraulic wet-disc brakes; ROPS canopy standard, optional cab with air conditioning .
  

Unique features clarifications

• Shuttle-shift transmission: A system allowing rapid directional changes—very handy during repetitive digging and loading.
  
• Dig depth vs extended reach: Understanding both standard and extended configurations matters when planning deliverables like trench depth or loading distances.
  
• ROC/ROPS: Roll-over protective structure ensures operator safety; optional AC cabs add comfort during long shifts.
  

Typical sale values and usage context
Used units from this era—with varying maintenance histories—are listed in the $20,000 to $30,000 range. One 1993 unit with about 7,650 operating hours was previously priced around $20,000 . Another 1995 unit was listed near $18,500 with over 9,000 hours . A 1994 model with 9,374 hours and enclosed air-conditioned cab listed for almost $29,900 .
Maintenance suggestions

• Fluid and filter intervals:
  • Engine oil and filter: every 100 hours
    
  • Fuel filter: around 200 hours
    
  • Hydraulic system: every 250 hours
    
  • Transmission fluid: checked also around 250 hours
    
  • Grease all pins and joints daily or before use .
    
• Common wear items:
  • Loader and backhoe linkage pins and bushings
    
  • Hydraulic hose connections, cylinder seals
    
  • Bucket teeth and coupler wear surfaces
    
  • Cooling system components like thermostats and water pumps.
    

Anecdote from a job site
A contractor once used a late-model 310D in urban utility work: its compact 7-ft width allowed easy navigation between city buildings, while the quick shuttle-shift enabled rapid back-and-forth between trench digging and loading dump bodies. Despite logging over 8,000 hours, the machine ran reliably each day—proof of its durable design and solid Deere heritage.
Practical suggestions

• Prioritize extended-reach features if daily work involves deep trenches or loading over high sides—it adds 20–25 percent reach.
  
• Check hydraulic flow rates periodically—low flow can slow cycle times and reduce bucket break-out force.
  
• Secure parts inventory: front loader pins, backhoe seals, and filter kits are still available from specialty suppliers.
  
• Use insulated cabs (if present) to reduce operator fatigue during extreme temperature conditions.
  

Wrap-up
The 1993 John Deere 310D stands as a testament to a rugged era of multi-task backhoe loaders. With a balance of lifting power, digging depth, and manageable size, it became a trusted companion for road, utility, and agricultural jobs. Supported by John Deere’s engineering pedigree and maintained wisely, it continues to be a capable performer even decades later—an enduring symbol of mid-90s construction machinery reliability.
