Why Operators Consider Switching Control Systems
Bobcat skid steers have evolved through multiple control configurations over the decades. Earlier models relied on mechanical foot pedals to operate the lift and tilt functions, while newer units introduced hand-actuated joystick systems—often integrated with electronic control modules like BICS (Bobcat Interlock Control System) and ACS/AHC (Advanced Control System/Attachment Control). Some operators, particularly those accustomed to older machines or seeking simpler mechanical feedback, prefer foot controls for their tactile response and reduced reliance on electronics.
Understanding the Mechanical and Hydraulic Differences
Converting a joystick-controlled Bobcat to foot pedal operation is not a plug-and-play task. The core challenge lies in the control valve architecture. Machines equipped with hand controls often use a valve block designed for electronic actuation, with solenoids controlling spool movement. Foot-controlled machines, by contrast, use mechanical linkages that directly manipulate the spools.
To perform a successful conversion, the following components must be addressed:
While the exact parts list varies by model, a typical conversion requires:
Field Experience and Conversion Outcomes
Conversions have been attempted with mixed results. One technician in Indiana retrofitted a Bobcat 753 with foot pedals sourced from a salvage yard. After disabling the ACS module and installing mechanical linkages, the machine operated reliably for grading and snow removal. Another operator in Oregon attempted the same on a newer S185 but encountered persistent fault codes due to the BICS system detecting missing joystick inputs.
In general, older models with simpler electronics are more amenable to conversion. Newer machines with integrated CAN bus systems and multiplexed controls may require dealer-level reprogramming or custom firmware.
Recommendations for a Successful Conversion
Replacing Bobcat hand controls with foot pedals is feasible but requires mechanical expertise and a clear understanding of the machine’s hydraulic and electronic systems. While the conversion can restore tactile control and simplify operation, it must be approached methodically to avoid disabling critical safety systems or triggering fault codes. For operators committed to mechanical simplicity, the effort may be worthwhile—especially on older models where electronics are minimal and parts are readily available.

Foot-controlled machines, by contrast, use mechanical linkages that directly manipulate the spools.
To perform a successful conversion, the following components must be addressed:
- Control valve compatibility: If the valve block is not designed for mechanical input, it must be replaced or modified.
- Pedal assemblies: Includes lift and tilt pedals, return springs, and mounting brackets.
- Linkage hardware: Rods, pins, bushings, and clips to connect pedals to valve spools.
- Instrument panel adjustments: Removal or bypass of joystick wiring and integration of pedal feedback, if applicable.
- ACS/AHC deactivation: The electronic control system must be disabled or reprogrammed to prevent fault codes and enable manual operation.
While the exact parts list varies by model, a typical conversion requires:
- Lift and tilt pedal assemblies
- Linkage rods and pivot hardware
- Modified or replacement valve block with mechanical spool actuation
- Deactivation or reconfiguration of ACS/AHC modules
- Optional: updated instrument panel or blanking plates

Recommendations for a Successful Conversion
- Verify control valve compatibility before purchasing parts.
- Source pedal assemblies and linkages from donor machines or OEM suppliers.
- Consult wiring diagrams to identify and disable ACS/AHC inputs.
- Test spool movement manually before finalizing linkage installation.
- Consider professional assistance for electronic bypass or reprogramming.
