The Rise of Bantam Cable Machines
The C350 Shield Bantam represents a bygone era of cable-operated excavators that once dominated job sites across North America. Bantam, a brand originally developed by Schield Bantam Company in Waverly, Iowa, was known for producing reliable and compact cable hoes and cranes from the 1940s through the 1970s. These machines were widely used in utility trenching, roadwork, and rural infrastructure projects before hydraulic systems became the industry standard.
The C350 model, in particular, was a mid-size cable backhoe designed for versatility. It featured a friction clutch system, mechanical brakes, and a series of interchangeable buckets ranging from 24 to 42 inches. Unlike hydraulic excavators, the C350 relied entirely on steel cables and pulleys to control boom, dipper, and bucket movements. This mechanical simplicity made it durable, field-serviceable, and ideal for remote operations.
Mechanical Design and Operation
The C350’s drivetrain was powered by a diesel engine coupled to a series of clutches and winches. Operators controlled the machine using foot pedals and hand levers that engaged friction drums to lift, swing, and dig. The absence of hydraulic fluid meant fewer leaks and less maintenance, but it also required a high level of skill to operate smoothly.
Key features included:
Collector Value and Restoration Culture
Today, the C350 is considered a collector’s item among vintage equipment enthusiasts. While few contractors use cable hoes for active work, many appreciate their historical value and mechanical elegance. Restored units with original glass, manuals, and working clutches can fetch upwards of $15,000, depending on condition and included accessories.
Restoration challenges include:
The Shift to Hydraulics and Industry Sentiment
The transition from cable to hydraulic excavators began in earnest during the 1960s and accelerated through the 1980s. Hydraulic systems offered smoother control, faster cycle times, and reduced operator fatigue. However, not all operators embraced the change. Some argued that cable machines allowed for more nuanced control in certain soil conditions and were easier to repair in the field.
Despite the shift, a niche community continues to preserve and operate cable machines. These enthusiasts often gather at vintage equipment shows, where machines like the C350 are demonstrated and admired. The tactile feedback of friction clutches and the rhythmic hum of cable drums evoke a sense of craftsmanship that modern machines lack.
Conclusion
The C350 Shield Bantam is more than a machine—it’s a symbol of an era when excavation required mechanical intuition and manual dexterity. While hydraulic systems have taken over the industry, the legacy of cable-operated equipment lives on through collectors, restorers, and those who still believe that old iron has stories worth telling. Whether preserved for nostalgia or operated for passion, the C350 remains a testament to the enduring spirit of early earthmoving innovation.

The absence of hydraulic fluid meant fewer leaks and less maintenance, but it also required a high level of skill to operate smoothly.
Key features included:
- Cable-operated boom and dipper arms
- Friction clutches for directional control
- Mechanical brakes for swing and travel functions
- No drum winch for crane boom—configured strictly as a backhoe
- Multiple bucket sizes for varied trench widths
Collector Value and Restoration Culture
Today, the C350 is considered a collector’s item among vintage equipment enthusiasts.

Restored units with original glass, manuals, and working clutches can fetch upwards of $15,000, depending on condition and included accessories.
Restoration challenges include:
- Locating clutch wrenches and specialty tools
- Sourcing friction materials and brake linings
- Replacing worn cables with proper tension ratings
- Rebuilding mechanical linkages without modern equivalents
