To get the most out of your zero-turn mower, ensure it’s well-maintained. To do this, all of its components must be in perfect functioning.

Hydraulic fluid is one of the most critical components to check!

 

What’s Required

  1. Acquire a thorough knowledge of how hydraulic systems function. Attempting to change the oil if you have little or no experience could damage the machine.
  2. The user’s manual must have been read. Manufacturers frequently give instructions on how to perform an oil change. You should familiarize yourself with the device before using it.
  3. Protect yourself from the ill effects by wearing gloves and safety eyewear.
  4. Now that you’re all set, go through the following procedures.

 

Basic Steps

Thirty minutes is the amount of time required.

1. Prepare Your Mower.

When you’re ready to remove the mower, turn it off, level it, and lift it with a jack. Before you may start the mower, you should turn off the engine.

2. Under the Drain Plug, Place a Bucket

Put a container under the drain plug after you’ve raised the mower off the ground. It is where a bucket or basin comes in helpful. The hydraulic fluid reservoir’s drain plug can be found here.

3. The Oil Is Now Flowing.

Remove the reservoir’s cover to allow the oil to flow freely into the container since the vacuum inside the reservoir lets out air trapped inside. The oil will flow more quickly if the cap is removed. Before beginning this process, you should have cleaned the area around the drain stopper. As a result, there will be no cross-contamination.

 4. Ensure that All of the Oil has been Completely Evaporated.

A wrench or a deep well socket is required for this stage. Use the tools to remove the drain cap. A deep well socket may be helpful if the plug is excessively tight or difficult to remove. After removing the cap, use clean water and a clean towel to remove any oil residue.  The hydraulic filter can now be removed.

5. Reinstalling the Filter.

When the oil has been drained, it is time to reinstall the drain stopper. You then reinstall the filter using an adjustable wrench. Apply oil to the gasket before installing the filter to ensure a proper seal.

6. Replace the Oil in the Tank.

Fill the reservoir with fresh oil. You should use a funnel to fill the tank’s tubing, which has a hole. The area around the reservoir should also be cleaned after adding a new oil supply.

 7. The Final Countdown

Turn the engine on and remove the reservoir’s top to flush out any air trapped in the lines or the oil filter. Check the oil level. You can add more oil if the level is too low.

 

Changing Hydraulic Fluid in a Zero-Turn Mower Is Necessary

The smooth operation of a zero-turn mower is mainly due to the use of hydraulic fluid. As a lubricant, it helps keep the mower’s hydraulic system functioning smoothly.

Hydraulic oil is critical to the operation of the entire system. Thus it must be in good working order. The mower’s performance may be harmed if the hydraulic oil isn’t changed after a while of heavy use.

It depends on how often you use your zero-turn mower.

As you’ve already established, hydraulic oil is critical to the mower’s hydraulic system. When it comes to zero-turn vehicles, the most common query will be how often to change the oil.

 

The Frequency of Changing Hydraulic Fluid

The frequency with which you mow will largely be determined by how often you use your mower. Quality of engine oil and operating conditions will also play a role in this.

After 100 hours of operation, it is recommended that the hydraulic fluid in an average mower be checked. If the mower’s oil is still in good condition, you can change it after 1000 hours of operation.

A lawnmower’s 1000-hour service life takes around six months to complete. If you don’t use the mower zero-turn mower too much, the six months should be fine. A shorter period should be adequate if you’re using it more frequently.

In most cases, the manufacturer will guide how often you should have your oil changed. The user’s guide contains these instructions.

 

Inquiries that Have Been Asked frequently (FAQs)

  • Is hydraulic fluid used in zero-turn mowers?

Transmission oil is required for zero-turn mowers with Hydro-Gear hydraulic gearboxes. If you’re going to utilize synthetic motor oil, your options are 15W-50 or 20W-50.

  • A zero-turn mower’s hydraulic fluid needs to be changed regularly?

You should replace the hydraulic fluid in your zero-turn mower after 1,200 hours of use.

  • Difference between hydraulic fluid and hydrostatic oil?

They’re not the same at all, no. A rust and oxidation-inhibited oil, hydraulic fluid works well in industrial and equipment settings. In contrast, hydrostatic oil is better suited to harsh environments, such as the outdoors in the winter.

  • Is hydrostatic transmission possible with hydraulic fluid?

Hydraulic fluid is used in hydrostatic transmission.

  • Hydraulic fluid is expensive, so what can you use in its place?

Hydraulic fluid can be replaced with any 10-20W motor or machine oil. Some vegetable seed oils and automatic transmission fluid can also serve as excellent substitutes. Moreover,

  • Is it possible to substitute motor oil for hydraulic fluid?

You can, but you should not because of the additives used in motor oil to increase the viscosity index of the product.
