How to check the hydraulic level on a Kubota L3400

To check the hydraulic fluid level  you can follow these steps:

  1. Park the tractor on a level surface and engage the parking brake for safety.
  2. Locate the hydraulic fluid reservoir. On the L3400, it is typically located on the left side of the tractor, near the clutch pedal, and has a small round sight glass
  3. Clean the area around the sight glass to ensure a clear view of the fluid level.
  4. With the engine off, remove the cap from the sight glass.
  5. Look through the sight glass to check the fluid level. The fluid should be visible and should touch the bottom of the sight glass when the reservoir is full. If the fluid level is below the sight glass, you may need to add more hydraulic fluid
  6. If you need to add hydraulic fluid, use a funnel to pour the fluid into the reservoir. Be careful not to overfill the reservoir, as this can cause damage to the hydraulic system.
  7. After adding or checking the hydraulic fluid level, securely replace the cap on the sight glass and ensure it is properly tightened.

How to take off the oil filter on a Kubota L3400

Changing the oil filter on a Kubota L3400 tractor is a relatively simple process, but it’s essential to follow safety precautions and use the right tools.

Tools and Materials You’ll Need:

  1. New oil filter
  2. Oil drain pan
  3. Oil filter wrench or strap wrench
  4. Disposable gloves
  5. Safety glasses

Steps to Remove the Oil Filter on a Kubota L3400:

  1. Prepare Your Work Area:
    • Park the tractor on a level surface and engage the parking brake.
    • Allow the engine to cool down if it has been running recently to avoid burns from hot oil.
    • Put on disposable gloves and safety glasses to protect your hands and eyes.
  2. Locate the Oil Filter:
    • The oil filter on the Kubota L3400 is typically located on the engine block. Refer to your tractor’s manual or consult a parts diagram if you’re unsure of its location.
  3. Position the Oil Drain Pan:
    • Place the oil drain pan underneath the oil filter to catch any oil that may spill when you remove it.
  4. Loosen the Oil Filter:
    • Use an oil filter wrench or strap wrench to loosen the oil filter. Turn it counterclockwise (lefty loosey) to loosen it.
    • Be prepared for some oil to start draining out when you break the seal. Ensure that the drain pan is properly positioned to catch the oil.
  5. Remove the Oil Filter:
    • Once the oil filter is loosened, continue turning it counterclockwise until you can unscrew it by hand.
    • Be cautious as you remove it to avoid spilling more oil.
    • Drain any remaining oil from the filter into the drain pan.
  6. Clean the Mounting Surface:
    • Use a clean, lint-free cloth or paper towel to wipe the mounting surface where the oil filter was attached. Ensure there are no old gasket remnants left behind.
  7. Prepare the New Oil Filter:
    • Before installing the new oil filter, apply a small amount of clean engine oil to the rubber gasket on the top of the filter. This will help create a good seal and make it easier to remove the filter during the next oil change.
  8. Install the New Oil Filter:
    • Screw the new oil filter onto the engine by hand. You don’t need to use a wrench for this step. Tighten it until the gasket makes contact with the mounting surface, then give it an additional 3/4 to 1 turn to secure it. Refer to the filter manufacturer’s instructions if there are specific guidelines.
  9. Dispose of the Old Oil Filter:
    • Dispose of the old oil filter properly. Most auto parts stores or recycling centers will accept used oil filters. Make sure to follow local environmental regulations for disposal.
  10. Add New Engine Oil:
    • After replacing the oil filter, you’ll need to add the appropriate amount of new engine oil to your Kubota L3400. Refer to your owner’s manual for the recommended oil type and capacity.
  11. Check for Leaks:
    • Start the engine and let it run for a few minutes, then check around the oil filter for any signs of leaks. If you notice any leaks, shut off the engine and tighten the filter slightly.
  12. Dispose of Old Oil:
    • Don’t forget to properly dispose of the used oil from the drain pan. Many auto parts stores or recycling centers offer oil recycling services.
  13. Record the Oil Change:
    • Make a note of the date and mileage (or hours) of your tractor to keep track of when the next oil change is due.
