Common Causes of Tilt Activation in Neutral
There are several potential causes for the tilt function continuing to engage when the Bobcat 743 is in neutral. The issue can range from simple electrical problems to more complex hydraulic malfunctions. Below are some of the most common reasons for this malfunction:
- Faulty Hydraulic Control Valve:
- The hydraulic control valve is responsible for directing hydraulic fluid to various functions, including the tilt system. If the valve is malfunctioning or stuck in the "on" position, it can cause the tilt to engage continuously, even when the machine is in neutral.
- The hydraulic control valve is responsible for directing hydraulic fluid to various functions, including the tilt system. If the valve is malfunctioning or stuck in the "on" position, it can cause the tilt to engage continuously, even when the machine is in neutral.
- Worn or Sticking Tilt Solenoid:
- The tilt solenoid controls the flow of hydraulic fluid to the tilt motor. If the solenoid becomes worn, damaged, or clogged, it can fail to deactivate when the machine is in neutral, causing the tilt to remain engaged.
- The tilt solenoid controls the flow of hydraulic fluid to the tilt motor. If the solenoid becomes worn, damaged, or clogged, it can fail to deactivate when the machine is in neutral, causing the tilt to remain engaged.
- Hydraulic Pressure Issues:
- Low hydraulic pressure or a pressure relief valve malfunction can lead to improper operation of the tilt system. If the system doesn’t receive the proper hydraulic pressure, the tilt function may engage unexpectedly, even when the machine is not actively being used.
- Low hydraulic pressure or a pressure relief valve malfunction can lead to improper operation of the tilt system. If the system doesn’t receive the proper hydraulic pressure, the tilt function may engage unexpectedly, even when the machine is not actively being used.
- Electrical Issues or Short Circuit:
- An electrical short, particularly in the tilt circuit, can cause the tilt function to activate unintentionally. This may occur due to damaged wiring or a malfunctioning switch that continues sending the "activate" signal even when the machine is in neutral.

- Faulty Joystick or Controls:
- If the joystick or other control components are malfunctioning, they may send incorrect signals to the hydraulic system, causing the tilt to engage when the machine is not in use.
- If the joystick or other control components are malfunctioning, they may send incorrect signals to the hydraulic system, causing the tilt to engage when the machine is not in use.
To troubleshoot and identify the source of the issue, follow these steps:
- Inspect the Hydraulic Control Valve:
- Check the hydraulic control valve for any signs of wear, leakage, or debris. A malfunctioning valve can cause hydraulic fluid to flow into the tilt circuit when it shouldn’t. Ensure that the valve is correctly positioned and functioning properly.
- Check the hydraulic control valve for any signs of wear, leakage, or debris. A malfunctioning valve can cause hydraulic fluid to flow into the tilt circuit when it shouldn’t. Ensure that the valve is correctly positioned and functioning properly.
- Test the Tilt Solenoid:
- Test the tilt solenoid to ensure it is functioning correctly. You can do this by checking the voltage at the solenoid and inspecting for any signs of wear or damage. If the solenoid is stuck in the "on" position, replacing it may resolve the issue.
