Switching from Cat to Deere Controls on Excavators

[MikePhua]

When it comes to heavy machinery, especially excavators, operators are often accustomed to a specific brand’s control layout. The choice of control system greatly affects the operator’s comfort and efficiency, and switching between different systems can be a challenging but necessary adjustment. A common scenario in the construction and heavy equipment industry is transitioning from Cat (Caterpillar) controls to Deere (John Deere) controls. This transition may happen for various reasons, such as switching brands, hiring new operators, or needing to adapt to a different fleet configuration.
This guide will cover the main differences between Cat and Deere controls, why an operator might need to make the switch, and tips on making the transition smoother and more effective.
Understanding Cat and Deere Control Systems
Both Cat and Deere excavators are renowned for their durability, performance, and advanced technology. However, they use different control systems, which can make switching between the two a bit challenging for operators used to one or the other.
1. Cat Controls:
Caterpillar’s control system is often referred to as the "joystick" or "pilot" system. The main characteristics of Cat controls are:

• Two-joystick operation: The operator uses two joysticks, one for the left hand and one for the right. Each joystick controls a specific side of the excavator (left and right tracks, boom, arm, and bucket).
  
• ISO pattern: The ISO control pattern, common to Cat machines, operates with the left joystick controlling the boom and arm, while the right joystick controls the swing and bucket functions.
  
• Ergonomics: Caterpillar’s joystick design is often praised for its comfort and ease of use, with features such as adjustable armrests and custom settings that help reduce operator fatigue during long shifts.
  

2. Deere Controls:
John Deere’s control system, while similar in many ways, differs slightly in terms of layout and feel:

• Single-joystick operation: Some Deere models use a single joystick for multiple functions, such as boom, arm, and bucket controls. This is especially common in smaller models or those designed for specific tasks.
  
• Wrist control for swing: In Deere’s system, the wrist control is often used for controlling the swing function, which may be an adjustment for those accustomed to using a joystick.
  
• Optional patterns: Deere offers multiple control patterns, such as the ISO and SAE patterns, allowing operators to customize their experience.
  

Reasons for Switching Control Systems
Switching control systems, whether for a fleet upgrade or job-specific requirements, might be necessary for the following reasons:

• Fleet Consistency: Large construction companies and contractors often standardize their fleet for consistency and efficiency. Switching from Cat to Deere controls may be part of fleet consolidation or a new equipment purchase.
  
• Operator Familiarity: Operators who are familiar with Deere controls may need to work on machines with Cat systems, or vice versa, depending on the project and available equipment.
  
• Maintenance or Repair Needs: A piece of equipment may need to be replaced or repaired, and the only available machine may have a different control system. In such cases, operators must quickly adjust to the new system to maintain productivity.
  

Challenges in Switching from Cat to Deere Controls
Switching from one control system to another can lead to several challenges, primarily stemming from the differences in control layout and ergonomics. Some of these challenges include:

• Muscle Memory: Operators accustomed to the feel of a particular system may find it difficult to adjust their muscle memory when using a different control layout. For instance, if an operator is used to controlling the boom with their left hand on a Cat machine, switching to Deere could initially feel awkward and inefficient.
  
• Control Patterns: Cat and Deere both offer different joystick patterns, and an operator switching systems may struggle to operate the machine smoothly if they aren’t familiar with the new pattern.
  
• Ergonomics and Comfort: The ergonomics of the cab, the size and position of the joysticks, and the feel of the control levers are all factors that contribute to the operator’s comfort and control. These differences might cause discomfort during long periods of operation.
  

Adapting to Deere Controls
The good news is that switching to Deere controls can be made easier by following a few tips and utilizing tools designed to help operators make a smoother transition.
1. Familiarize Yourself with the New Control Layout:

• Study the User Manual: Before operating a Deere excavator, it’s crucial to familiarize yourself with the layout and functions of the controls. Deere’s user manuals often include diagrams and tips on how to adapt the control system to your preferences.
  
• Practice in a Simulated Environment: If possible, practice in a non-operational setting or on a machine that is not in use. This allows the operator to get a feel for the controls without the pressure of real-time work.
  

2. Control Pattern Changeover:

• Switching between ISO and SAE: Many Deere machines offer the ability to switch between control patterns, such as the ISO and SAE patterns. Operators who are used to one pattern on Cat machines can adjust the Deere system by switching to the same pattern, making the transition smoother.
  
• Adjusting for Muscle Memory: The best way to overcome muscle memory challenges is to spend time practicing the movements associated with each function. For example, boom movements may be controlled differently on Deere than on Cat, so it’s important to practice until the movement feels natural.
  

3. Ergonomics Adjustment:

• Seat and Armrest Position: Deere machines may have different seat and armrest settings compared to Cat machines. Adjust the seat and armrests to ensure a comfortable position before starting operation.
  
• Joystick Adjustment: Take time to adjust the joysticks to fit your comfort level. Some Deere machines may allow you to adjust the joystick angle and resistance, similar to the customization available on Cat systems.
  

4. Operator Training and Education:

• Training Programs: Many dealers and manufacturers offer training programs that help operators understand and adapt to new control systems. Enrolling in these programs can provide in-depth guidance and ensure safe operation.
  
• Peer Support: Talking to other operators who are familiar with Deere machines can provide valuable tips and tricks for overcoming initial difficulties.
  

Conclusion
Switching from Cat to Deere controls is a process that requires patience, practice, and understanding of the different control systems involved. While the systems may differ in layout, ergonomics, and functionality, operators can adapt to the new systems through practice, training, and minor adjustments. The transition doesn’t have to be overwhelming, and with the right tools and resources, operators can efficiently operate Deere machinery and maintain productivity on the job. Whether for a fleet upgrade, a specific project, or a machine replacement, the ability to adapt to different control systems is an essential skill for modern operators in the heavy equipment industry.
