The MDI Yutani MD140B excavator is a versatile and reliable machine widely used in the construction, mining, and demolition industries. Its design incorporates several features aimed at enhancing operational efficiency, comfort, and ease of use for the operator. One critical feature of many modern excavators, including the Yutani MD140B, is the ability to change control patterns. This allows operators to customize the machine's control system to suit their preferences or specific tasks. This article provides a comprehensive guide on how to change control patterns on the MDI Yutani MD140B, the options available, and considerations when making the switch.
Understanding Control Patterns in Excavators
Before diving into the specifics of the MDI Yutani MD140B, it's important to understand what control patterns are and why they matter. Excavator controls refer to the way the machine’s movements are controlled by the operator through the joystick or lever system. The two most common control patterns used in excavators are:
Why Change the Control Pattern?
There are several reasons an operator or fleet manager might want to switch control patterns:
The MDI Yutani MD140B is designed with operator customization in mind, and its control pattern can be changed to suit different preferences. Below is a general overview of the steps involved in changing the control pattern on this model:
1. Access the Control Pattern Selector
Most modern excavators, including the MD140B, feature a control pattern switch located in an accessible area within the cabin. This switch might be a physical lever, a button on the dashboard, or part of the joystick. In some cases, the control pattern selector may require the use of a key or tool to adjust, depending on the machine’s configuration.
2. Choose Between ISO or SAE Pattern
Once the pattern selector is accessed, the operator can switch between the ISO and SAE patterns. The exact method of switching may vary based on the model, but it generally involves either moving the lever or pressing a button to toggle between the two options. Some excavators may even offer programmable controls, allowing operators to save their preferred pattern for quick access.
3. Confirm the Change
After switching the control pattern, it is important to confirm that the settings have been correctly applied. This can be done by performing a few simple movements such as extending and retracting the boom, swinging the arm, or using the bucket. If the controls do not respond as expected, it may be necessary to troubleshoot the pattern selection process or refer to the machine’s manual for further instructions.
Additional Options for Customization
Beyond the basic switch between ISO and SAE patterns, the MDI Yutani MD140B may offer further customization options to improve the operator’s experience:
1. Adjustable Joystick Sensitivity
Some excavators, including the MD140B, offer adjustable joystick sensitivity. This allows operators to fine-tune the responsiveness of the joysticks, ensuring they can control movements with precision. Whether the task requires quick, aggressive movements or slow, deliberate precision, adjustable sensitivity can improve control.
2. Seat Position and Ergonomics
While changing the control pattern can impact the way the operator interacts with the machine, the seat positioning and ergonomics also play a significant role in comfort. The MD140B offers an adjustable seat that can be fine-tuned to accommodate the operator's body type and preferences. Ensuring proper posture can reduce fatigue, especially during long shifts.
3. Customizable Display Settings
Modern excavators come with digital displays that offer detailed machine diagnostics and real-time data. On the MD140B, the display can be adjusted to show important information such as engine performance, hydraulic flow, fuel levels, and operating hours. Customizing these settings allows operators to focus on the information that’s most relevant to their work.

Understanding Control Patterns in Excavators
Before diving into the specifics of the MDI Yutani MD140B, it's important to understand what control patterns are and why they matter. Excavator controls refer to the way the machine’s movements are controlled by the operator through the joystick or lever system. The two most common control patterns used in excavators are:
- ISO Pattern: This is the most widely used control pattern in modern excavators. It is known for its straightforward design where the left joystick controls the boom and arm, and the right joystick controls the bucket and swing. This setup is intuitive for many operators and is commonly found in North American and European equipment.
- SAE Pattern (also known as JIC): This control pattern is commonly used in the United States. In this pattern, the left joystick controls the bucket, while the right joystick controls the boom and arm. Operators who are accustomed to this setup may prefer it for its familiarity.
Why Change the Control Pattern?
There are several reasons an operator or fleet manager might want to switch control patterns:
- Personal Preference: Some operators may have learned using one pattern and are more comfortable with it. Switching the pattern allows the operator to feel more at ease and productive.
- Task-Specific Needs: Certain tasks may be more suited to one pattern over the other. For example, using ISO controls may be more intuitive when performing precise digging or trenching tasks, whereas SAE controls might be preferred for tasks that involve a lot of lifting and maneuvering of heavy loads.
- Operator Training: When training new operators, adjusting the control pattern can make the machine easier to learn based on the trainee’s experience or familiarity with certain patterns.
- Ergonomics: Some patterns may feel more natural in terms of hand positioning or movement, potentially reducing operator fatigue during long working hours.

While the ability to change control patterns offers significant benefits, there are a few things to keep in mind:
- Training: If the control pattern is changed, it’s essential that the operator receives proper training on how to use the new setup. Inexperienced operators may need time to adjust to a different pattern, especially if switching from SAE to ISO or vice versa.
- Transition Period: It’s not uncommon for operators to experience a transition period when switching control patterns. During this time, there may be a slight drop in productivity as the operator adjusts to the new controls. Providing support during this time can help smooth the transition.
- Compatibility with Other Equipment: If operators work with multiple machines, some of which may not offer customizable control patterns, it’s worth considering how frequently the control pattern needs to be changed. In some cases, consistent practice with one pattern might be more efficient in the long run.
The ability to change the control pattern on the MDI Yutani MD140B offers several key benefits for operators and fleet managers alike:
- Increased Comfort: Operators can select the control pattern that feels most natural to them, reducing strain and increasing overall comfort during long shifts.
