How to checking hydraulic fluid John Deere 4755 Problems

Just like your car’s oil, transmission fluid, and antifreeze need to be topped up every season, your tractor’s hydraulic fluid should be checked and added when it’s low. It is recommended to check the fluid levels after 50 hours of use or every week. Add liquid only if necessary. Checking the hydraulic fluid itself is a lot like reading a dipstick, but there are a few things to keep in mind.


Check the hydraulic fluid level when the tractor is cold. Make sure the vehicle is on level ground. Lower the boom and buckets & nbsp; cylinders. This is not just to make sure the machine is in a good position, but to keep it safe while checking the deposit.

While checking the fluid, do not let dirt get into the reservoir or dipstick.

  • Remove the filler cap, which is normally located behind the driver’s seat on John Deere tractors. On some models, you may need to remove a side panel and engine cover.
  • Take out the dipstick and read the level. If it is not low, it is not necessary to add liquid.
  • If you need to add fluid, use a clean funnel to pour the oil into the reservoir slowly. Add some liquid and then check the level to make sure you don’t overfill the reservoir. Once the level is full, replace the dipstick and cap. Reinstall the side panel or motor covers.


It is recommended to change the hydraulic fluid and filter every 1,200 hours of use. That’s about 30 weeks if you run your tractor 40 hours / week on average.

You should probably change the oil annually, but it depends on how hard your tractor works.

Although it may seem intimidating, if you can change the oil in your car, you can change the hydraulic fluid in your tractor. Consult your owner’s manual for the exact location of the plugs and filters.

  1. Drive the tractor to warm up the engine. The fluid will be easier to wash off if it is hot. Any contaminant that is deposited while the tractor is stopped will mix with the fluid, causing it to be washed away.
  2. Prepare your hydraulic equipment. You will need buckets to collect the fluids.
  3. Remove the drain plug to drain the fluid.
  4. Clean the grates.
  5. Replace the filter.
  6. Replace the cap.
  7. Fill with hydraulic fluid. The amount you need will depend on the make and model of your tractor. Your owner’s manual should provide information on the amount of filler or ask your dealer.
  8. Let the engine run for 30 seconds to 1 minute. Turn the steering wheel in each direction to make sure it works.
