Taking the water temperature gauge of the 4430 John Deere tractor as an example: this series of instruments is driven by a magnetic and stepper motor pointer; Accurate indication, the key pointer automatically returns to its original position when the vehicle is stopped and turned off. Replace the old cross coil instrument. 

Features: 1. 24V/12V voltage, automatic overvoltage protection. 2. There are installation holes with diameters ranging from 85 to 55mm. 3. The Odometer mileage or Tachometer total time is displayed on the LCD. 4. The mileage ratio and engine speed to gear ratio can be set arbitrarily according to requirements (some models). 5. Instrument stepper motor drive pointer, LED (light emitting diode) backlight, with automatic and non automatic backlight; The pointer glows. 6. Water and oil meters are controlled using energy-saving software; The instrument consumes less power and can extend the lifespan of water temperature plugs, oil floats, and pressure sensors. This series of instruments is used for heavy-duty trucks , cranes , mining machinery , cleaning vehicles , ships , and other purposes . The products are of high quality and low price, and can replace VDO (Siemens), CURTIS (Curtis) , Cummins and other instruments . Customizable according to appearance, color, dial, etc. Welcome to send your request to us.

The normal range of tractor water temperature is between 80 ℃ and 90 ℃ . When the water temperature exceeds 90 ℃, we need to pay attention to whether it is too high . Judgment method: 1. Observe the water temperature gauge. The water temperature gauge of a tractor is usually located on the dashboard in the cab , and we can determine whether the water temperature is too high by observing the pointer on the water temperature gauge . If the pointer stays in the red area for a long time , it indicates that the water temperature is too high and measures need to be taken in a timely manner . 2. Listen to the engine sound. If abnormal noise or hissing sound is heard while the tractor engine is working , and the pointer of the water temperature gauge continues to move towards the high-temperature area , it is likely caused by high water temperature . At this point , it is necessary to immediately stop and check if the tractor has any faults.
