• The hydrostatic drive ensures smooth control and simple, mechanical operator controls ease serviceability.
  
• Operator station includes roll-over protection, basic instrumentation, floodlights, and ergonomic hand controls with safety interlocks.
  

Strengths and Practical Advantages

• The 4-390 engine provides reliable torque for digging and lifting in this class of machine.
  
• Its hydrostatic drive combined with balanced hydraulics delivers consistent performance and less operator fatigue.
  
• Typically compatible with hydraulic attachments due to its 16 GPM flow.
  
• Its sturdy frame and simple control layout contribute to long life and lower maintenance needs.
  

Considerations for Buyers
Before purchasing a used 1845C, check:

• Hydraulic oil cleanliness and operation of the control valve.
  
• Wear on drive motors and transmission fit—motor whine or vibration can indicate internal wear.
  
• Leaks around lift arms; seals in remote cylinders may degrade.
  
• Steering speed and bucket response; sluggish behavior could suggest caution valve or pump wear.
  

Maintenance Recommendations

• Change engine oil and fuel filters every 250 hours; hydraulic filters every 500 hours.
  
• Daily or weekly lubrication of pins and bushings, especially in dusty conditions.
  
• Keep tires at correct pressure and inspect for wear.
  
• Monitor for early symptoms of wear such as soft hydraulics or drive lag.
  

Use Case Snapshot
A contractor specializing in light demolition found that equipping his 1996 model with higher-flow auxiliary hydraulics allowed him to run a grapple attachment seamlessly, slashing material handling time on-site by up to 20%. The upgrade highlighted the loader’s adaptability and strong hydraulic base.
Case Industrial Heritage
Case Construction Equipment has roots dating back to 1842, becoming a leading manufacturer of agricultural and construction machines. Their skid-steer line, launched after acquiring Universal Loader Co in 1968, reached significant milestones including producing hundreds of thousands of loaders by the 2000s. The 1845C continues that legacy as a midline model offering durability, practical performance, and strong aftermarket support.
Summary Overview
The Case 1845C represents a practical balance between power, reliability, and versatility. Its 57-hp 4-390 diesel engine, hydrostatic drive, and dependable hydraulics make it well-suited for diverse mid-scale tasks. When evaluating a used unit, focus on hydraulic condition, drive components, and wear patterns. For buyers needing a skid steer that combines uptime, serviceability, and robust capability, a well-maintained 1845C remains a compelling choice.
