3 Simple Ways of Changing the Hydro Oil in Your Wright Stander

Hydro fluid plays a vital role in the performance of your Wright Stander Mower. When it’s regularly changed, and your engine in excellent condition, your mower’s output can be surprising; When it’s neglected, contaminants can accumulate and cause the system to fail.

With that in mind, how can you effectively drain the hydro oil in your Wright Stander mower? Here are three simple ways that you can include in the DIY maintenance routine of your Wright Stander mower.

Using an Oil Extractor

Draining hydro oil through an oil extractor is the easiest method of changing your hydro oil. It will merely require an oil extractor which has a small silicon tube which you dip in your Wright Stander’s hydro oil reserve tank and once it is in, you make it suck the hydro fluid by pumping the vacuum siphon. After you have finished sucking the hydro oil you will do the following:

    • Place a shopping bag below the filter, untie the hydro oil filter and drain all the remaining oil.
    • Clean up any remaining hydro oil around the filter area.
    • Get a new filter and using a marker, label on it the date on which you have changed the filter.
    • Dip your finger in the waste oil and smear it around the filter’s gasket seal.
    • Place the filter in its place and tighten it with your hand.
    • Using a clean funnel, fill up the reserve tank with new hydro oil to the recommended level.
    • Open the bypass valve on hydro pumps of your mower around a half-way counterclockwise to purge it and bleed all the trapped air in the system.
    • Lift your equipment’s rear part and make sure its rear wheels aren’t touching the ground.
    • Start the engine and gently move the control levers in the forward and reverse direction five to six time.
    • Turn the engine off and close the bypass valves.
    • Check the hydro oil level and fill it up if necessary.
    • Start the engine again and gently move the control levers in the forward and reverse direction five to six times with the bypass valves closed.
    • Turn off the engine and lower down the rear wheels of your wright stander.
    • At this point, your mower is now ready to run.

Draining from the Filter

With this method, all the hydro oil is drained from the hydro filter area by:

  • Place a plastic bottle scoop or a box in a way that will allow the oil to pour into a waste container.
  • Un-tie the filter and let the oil flow freely into the waste oil container.
  • Allow all the hydro oil to drain and clean the filter area of any remaining hydro oil.
  • Get the new filter and use a marker to label the date on which you have changed the filter.
  • Dip your finger in the waste oil and smear it around the new filter’s gasket seal.
  • Place the new filter in its place and tighten.
  • Get a clean funnel and fill up the reserve tank with the new hydro oil to the right level.
  • Open the bypass valves on the hydro pumps in a half-way counterclockwise direction.
  • Lift your equipment’s rear part and make sure its rear wheels aren’t touching the ground.
  • Start the engine and gently move the control levers in the forward and reverse direction five to six times to purge any trapped air in the hydro system.
  • Turn the engine off and close the bypass valves.
  • Check the level of the hydro oil in the reserve tank and fill up to the required level if necessary.
  • Start the engine and gently move the control levers in the forward and reverse direction five to six times with the bypass valves on the hydro pumps closed.
  • Turn off the engine and lower your mower’s drive wheels back to the ground.
  • Start the engine again and purge the mower this time with your load on it.
  • Turn of the engine. At this point, your mower is now ready for use.

Draining Through One of the Motor Lines

Some situations might require you to remove the hydro oil through the motor lines for example, if the filter is so tight that it fails to open and there are no alternatives like a vacuum siphon.

In this case, you will have to use a wrench and open one of the motor lines to drain the hydro oil through it. Though not recommended, at times things might fail, and you end up having it as an alternative.

Once you have successfully drained the hydro oil follow the same procedures as those mentioned in the other methods to purge any trapped air in the hydro system.

A hydro oil change in a wright stander does not need to be complicated to delay your maintenance process just because you are waiting for skilled personnel to do it for you. With proper instructions, you can do it yourself.

  1. Good to know. I have a question, my stander 52 makes unusual noise in d rear wheels. What might be the problem?

  2. Issues with unusual noise in the rear wheels are related to your hydro system. It could be that the last time you made a hydro oil change you didn’t properly purge the trapped air out. Secondly, it could be that your motors have problems. Does any of your motor show signs of leakage? Let me know as soon as possible so that I can figure out more possible issues. 🙂
