If You Could Special Order a Track Hoe

The Evolution of the Hydraulic Excavator
Hydraulic excavators, often referred to as track hoes, have undergone dramatic transformation since their inception in the mid-20th century. Originally developed as cable-operated shovels, the transition to hydraulic systems in the 1960s revolutionized earthmoving efficiency. Companies like Caterpillar, Komatsu, Hitachi, and Volvo have since refined the design, each contributing unique innovations in powertrain, hydraulics, operator comfort, and control systems.
By 2020, global sales of hydraulic excavators exceeded 500,000 units annually, with Asia-Pacific accounting for nearly 60% of the market. The machines range from compact 1-ton units for landscaping to massive 90-ton behemoths used in mining. Yet, despite the diversity, operators often dream of a “perfect” machine—one that blends the best features from multiple manufacturers.
What Would the Ideal Track Hoe Look Like
If given the chance to custom-build a track hoe from scratch, seasoned operators and mechanics would likely draw from a variety of brands to create a hybrid machine tailored to real-world demands. The following components are frequently cited as desirable:

• Engine: A Cummins QSB6.7 turbo diesel for its fuel efficiency and torque curve, paired with a variable geometry turbocharger for low-end response.
  
• Hydraulic System: Komatsu’s closed-center load-sensing hydraulics, known for fast cycle times and smooth multi-function control.
  
• Undercarriage: Caterpillar’s high-wide forestry undercarriage with tilt capability, offering superior ground clearance and slope stability.
  
• Cab Design: Volvo’s spacious operator station with panoramic visibility, climate control, and ergonomic joystick layout.
  
• Control Interface: A touchscreen panel with integrated calculator, diagnostics, and GPS heads-up display.
  
• Tool Storage: Side-mounted compartments for grease guns, spanners, rags, and 11"x17" site plans—accessible without standing or turning.
  
• Precision Mode: A rocker switch on the joystick to toggle between high-flow “rock and roll” mode and low-flow “craning” mode for delicate lifts.
  
• Safety Features: A secure pin-grabber hitch, backup camera, and reinforced rollover protection structure (ROPS).
  
• Entertainment and Connectivity: Satellite radio, subwoofer system, and optional cell signal booster—though some operators prefer silence to detect mechanical issues.
  

Operator Preferences and Field Realities
While some operators favor high-tech features, others emphasize mechanical simplicity and sensory awareness. One veteran recalled his father removing radios from new machines, insisting that distractions could mask critical sounds like bearing failure or hydraulic cavitation. This philosophy persists in some regions, where auditory diagnostics remain a key part of daily inspection.
Others prioritize visibility and cab layout. A long undercarriage (UC) improves stability and trenching accuracy, while unobstructed sightlines—especially upward—are essential for demolition and utility work. In aggregate operations, quick transitions between attachments require intuitive controls and accessible tools.
The Elusive Self-Cleaning Undercarriage
One universally desired feature is a self-cleaning undercarriage. Mud, clay, and debris buildup can add hundreds of pounds to the machine, increasing fuel consumption and wear. While no manufacturer has perfected this yet, experimental designs include:

• Oscillating track frames to shake off debris
  
• Hydrophobic coatings on track rollers and idlers
  
• Integrated water jets for periodic flushing
  

A Canadian startup recently tested a prototype with vibrating track guards, reducing buildup by 40% in field trials. If commercialized, this innovation could save operators thousands in maintenance costs annually.
Brand Loyalty vs. Functional Integration
Some operators remain loyal to a single brand, citing reliability and dealer support. However, others advocate for a modular approach—selecting components based on performance rather than manufacturer. For example:

• Use Caterpillar steel for durability
  
• Install Hitachi pumps for hydraulic finesse
  
• Add Kobelco’s power management system for fuel savings
  
• Finish with JCB’s JS-series cab for comfort
  

This “one piece at a time” philosophy echoes the spirit of Johnny Cash’s famous song, where a car was built from parts smuggled out of a factory over years. In reality, such integration is rare due to proprietary designs and warranty limitations, but the concept remains popular among independent owner-operators.
Support Infrastructure Matters More Than Perfection
Even the most advanced machine is only as good as its support network. Operators frequently note that parts availability, dealer responsiveness, and technical training outweigh minor design flaws. A well-supported machine can be kept running indefinitely, while a poorly backed unit may sit idle for weeks awaiting parts.
In one case, a contractor in Alberta retrofitted a Deere 350D with a Cat undercarriage and custom cab electronics. While the machine performed admirably, sourcing parts became a logistical challenge. Eventually, the operator partnered with a local dealer to stock hybrid components, turning the machine into a regional showcase.
Conclusion
The dream of a custom-built track hoe reflects the practical wisdom of those who operate them daily. By blending the best features from multiple manufacturers, operators envision machines that are not only powerful and efficient but also intuitive, safe, and comfortable. While commercial realities may limit such customization, the conversation itself drives innovation. Manufacturers who listen to these insights—whether about tool storage, hydraulic modes, or cab ergonomics—are more likely to produce machines that truly meet the demands of the jobsite.
