How To Check Hydraulic Fluid On John Deere Tractor

Our tractor’s hydraulic system allows us to perform heavy tasks with minimal effort. This system is based on fluid mechanics, so we need to monitor the volume of this fluid regularly. But how to check hydraulic fluid on John Deere tractor? You can easily check it from the hydraulic reservoir dipstick.

Running out of Hydraulic fluid is not an option for us as this cripples your hydraulic apparatus and steering for a few models.

Therefore, we will also answer when and how frequently you should check the hydraulic fluid and the conduct of filling it into your tractor in today’s discussion.

When Should You Check Hydraulic Fluid On John Deere Tractor

The conduct of keeping your tractor sound and running requires performing a check of the hydraulic fluid level at least once within every 1000 hours of operation on the engine. This is a generous gap, to be exact, we recommended checking it more frequently, as it does not require much effort.

Moreover, after you refill the hydraulic fluid, check the fluid level after the first 100 hours of use. This is to check if the fluid level is optimum and if there is any leakage in the system.

Refill liquid and reattach filter at least once every 1200 hours on the engine. There is more on how to refill the liquid mentioned above.

When Should You Refill Hydraulic Fluid In Your Tractor

You should opt for refilling when the fluid level gets lower than the lowest optimum level as shown by the scale.

Moreover, the fluid and filter need to be changed at least once after 1200 hours run. One refill will keep your tractor running for a long time.

However, the best measure is to check for unwanted drainage after a hundred hours of engine operation after a refill.

How To Refill Hydraulic Fluid

Refilling hydraulic fluid can be a little stressful as it requires a lot of preparation. Changing hydraulic liquid involves draining all previous liquid as their property is damaged, and they usually get compressed beyond efficiency level. It also helps preserve the health of the John Deere tractor hydraulic system.

To change the fluid, put on gloves and lay some buckets under the drain pipe. Unscrew each drain bolt and the filter and drain all the hydraulic fluids from them, fixing your tractor on ground level the whole time.

Four-Wheel tractors will have more drain valves than two-wheel drives. Make sure to miss none.

Now, before pouring new fluid, attach the bolt again and install a new filter. Before installing, dip it with the John Deere hydraulic oil so that your pump doesn’t run dry.

Then, remove the cap from the fluid tank and pour it with hydraulic fluid little by little through a clean funnel. Don’t overflow and do frequent John Deere hydraulic fluid checks.

The liquid will take some time to spread and give out proper reading. When the fluid reaches maximum capacity, stop and put on the cap tightly again. Be careful so that no dust or debris falls inside. Moreover, don’t overpour much at a time as it may form air vessels that might disrupt fluid potency.

Frequently Asked Questions (FAQs)

Do you check hydraulic fluid with the tractor running?
