Here’s a step-by-step guide on how to tighten the fan belt on a Kubota L2850:
Note: Before starting any maintenance or adjustment, ensure that the tractor is turned off and the key is removed from the ignition to prevent accidental starts.
- Locate the Fan Belt:
- Identify the fan belt on the Kubota L2850. The fan belt is typically visible on the front of the engine and connects the engine’s crankshaft pulley to the radiator fan.
- Inspect the Belt:
- Examine the condition of the fan belt. Look for signs of wear, damage, or fraying. If the belt is in poor condition, it may be necessary to replace it.
- Check Belt Tension:
- Press down on the middle section of the fan belt with moderate pressure. Ideally, the belt should have a slight amount of give but should not feel excessively loose or tight.
- Locate the Tension Adjustment Mechanism:
- Kubota tractors typically have a tension adjustment mechanism for the fan belt. This can be a tensioner pulley or an adjustable bracket.
- Loosen the Adjusting Bolt:
- If there is an adjusting bolt on the tensioner pulley or bracket, use the appropriate tool (such as a wrench or socket) to loosen it. This will allow the tensioner to move freely.
- Adjust the Tension:
- Using the appropriate tool, move the tensioner pulley or adjust the bracket to increase tension on the fan belt. Refer to the tractor’s manual for the specific adjustment procedure and recommended tension.
- Check Tension Again:
- After adjusting the tension, check the tension of the fan belt again by pressing down on the middle section. Ensure that the tension is within the recommended range.

- Insert the Dipstick:
- Insert the clean dipstick fully into the dipstick tube. Make sure it goes all the way in to get an accurate reading.
- Remove the Dipstick:
- Withdraw the dipstick from the tube and observe the oil level on the markings or indicators on the dipstick.
- Check the Oil Level:
- The dipstick will have two markings: one for the minimum oil level and another for the maximum oil level. The oil level should fall between these two marks. If the oil level is below the minimum mark, additional oil is needed.
- Inspect the Oil Condition:
- While checking the oil level, also inspect the condition of the oil. It should be a clear, amber color. If the oil appears dark or murky, it may be an indication that an oil change is needed.
- Add Oil if Necessary:
- If the oil level is below the minimum mark, add the appropriate type and grade of engine oil recommended by Kubota. Use a funnel to pour the oil slowly to avoid spills.
- Recheck the Oil Level:
- After adding oil, wait a moment for it to settle, then reinsert the dipstick and check the oil level again to ensure it falls within the recommended range.
- Secure the Dipstick:
- Once satisfied with the oil level, securely insert the dipstick back into the dipstick tube and ensure it is properly seated.
- Dispose of Used Oil Properly:
- If you’ve performed an oil change or topped up the oil, dispose of used oil in accordance with local regulations. Many auto parts stores and recycling centres accept used oil for proper disposal.
