Step 1: Begin by Raising the Mower

Step 2: Check the Fluid Levels

You’ll need to check and ensure that the fluid levels of your hydrostatic drive are at the right levels. Too much or too little can affect performance and cause damage, so it’s important you get this right. To check the fluid levels, you will need to use a hydrometer. You can find one in your local hardware store or online for a reasonable price.

Step 3: Clean and Lubricate

Using either turpentine or mineral spirits, it’s important that you clean and lubricate any areas of the hydrostatic drive that may have become grimy or rusty. Doing this will also help ensure all parts of the mower are working properly and efficiently. While cleaning, be sure to pay extra attention to the gears and drive chains.

Step 4: Adjust the Speed

Now, it’s time to adjust the speed of your hydrostatic drive. There are a few different methods you can use to do this depending on what type of Husqvarna mower you have. Generally speaking, however, you will need to use the socket set and wrenches to loosen the nuts or bolts that are adjusting the speed.

Step 5: Test it Out

Once you have adjusted the hydrostatic drive, it’s important to test it out before actually using it. To do this, turn on your mower and take it for a spin around your yard. Pay attention to how it responds, the speed, and any strange noises it might be making. If anything feels off or not quite right, you may need to go back and adjust it further until it’s just right.

Step 6: Neutralize (If Needed)

Finally, if your hydrostatic drive is still feeling a bit wonky after your adjustments, you may need to neutralize it. Doing so will help smooth out the operation and minimize wear and tear on the mower’s components. To do this, add a small amount of neutralizer to the fluid mixture that is used in the hydrostatic drive system.
