How to Make a Hydrostatic Lawn mower Faster?

Are you fed up with the speed of your hydrostatic lawnmower? Do you feel that it has slowed down since you purchased it and continues to decrease over time? It can be frustrating if you have a larger lawn to mow and it takes up your entire day or half of it. Gardening is a hobby that you enjoy in your leisure time to connect with nature, but a slow hydrostatic mower can take up all of your free time and leave you tired.

Don’t despair, though! In this blog, I will share some practical tips to increase the speed and performance of your hydrostatic lawnmower easily by following some simple steps. These steps will work only if your mower engine is in perfect condition. If your lawnmower engine is malfunctioning, these steps will not increase the speed, so it is essential to inspect and check your mower to assess the engine’s condition before attempting any modifications.


An ordinary mower has a mechanical transmission, which uses a gear to transfer power from the engine to the wheels by using a manual gear system. On the other hand, hydrostatic lawnmowers use hydraulic transmission, which uses a hydraulic pump and motor to transfer power to the wheels. You can use the lever to shift the pedal to control the speed.

Over the time span, the hydrostatic mower gets slower and the speed is decreased due to several reasons like different leaks, deteriorated tires, and other small issues. You can increase the speed and performance of your mower engine perfectly.


In the first step, before jumping into the modifications I have a checklist, you must complete this checklist prior to modification. This checklist will help you assess your mower whether modification works or not. These are the simple things you may not notice in general during your mowing activity

  • Check the condition tires
  • Check the fluid level
  • Check the oil & air filter
  • Check engine and other seals for any leak
  • Other damages
  • Any unusual sound while running your mower

This checklist is very important if your tires have deteriorated, your fluid level is low, you never change the oil and air filter and your engine seals deteriorate. It means that your mower needs servicing so go for servicing instead of modification. Maybe by doing recommended servicing and maintenance your speed issue resolved without modifications. If this is not the case then you must go for modifications


Now assessing the checklist, start modifying your lawnmower carefully. Do all the steps very carefully with the proper tools so that you do not get injured. Always follow the basic safety rules.

Replacing the tires

The first modification in your mower is to replace the company-provided tires and install bigger tires. Larger tires mean that they can move the larger area in a one-wheel cycle so ultimately creating a difference in the mowing speed. This is a mandatory modification and a lot of users are satisfied with this change. But before replacing the tires you must know the tire size of your mower because it may vary with different manufacturers. You can easily find the tire size by reading the instruction manual of your lawnmower or checking online. After getting the size now check the market for a bigger tire in this size. Normally, you can easily find the best-suited tire in the market.

Replace or sharpen the blades

The second recommended modification is to replace the dull and deteriorated blades. Some users do not care about the blade condition and never inspect so this will lead to slow down your mower. Because when you mow the grass, if the blades are not sharp it will damage the root and resultantly decrease the speed.

Buying new blades are expensive for some user so in this case, you may sharpen the mower blades easily on your own. To sharpen the lawnmower blades on your own read another article on this topic and by reading that blog you can easily sharpen the blades, which ultimately changes the speed of your mower.

Remove the Governor

Another modification is to remove the Governor. Governor is used to limiting the engine torque and motor rpm. There is an option to remove the governor. Removing it will definitely speed up your mower but it’s dangerous sometimes because rpm is not limited and you need to be careful if your kids or pets are also in the garden. Your lawnmower may be over speedy and out of control so always be careful if you remove the governor from your machine.

You can easily find the governor. In case you cannot find it you may check the instruction manual. These manuals contain all the necessary information about your lawnmower parts so you can easily find the governor location.


Some people overburden the mower with a lot of extra attachments like making the mower a car. I recommend that you remove all the attachments and only install them when you are using them. Doing this definitely creates a difference because the weight also creates an impact on the speed of your mower.


Similarly, you can use more powerful fuel in the mower. When you are using a powerful fuel it will increase the efficiency of your lawnmower and ultimately the speed is increased. Although, many people are thinking that nothing will happen with this, believe me, this will create a difference in the long run.

Speed Up Your Lawnmower with a Pulley Swap

If you want to make your hydrostatic lawn mower faster and transform your lawn mowing experience, consider a pulley swap. This simple modification can significantly boost your mower’s speed and efficiency. Here’s how it works:

What’s a Pulley Swap?: A pulley swap involves changing the size of the pulley on your hydrostatic mower’s transmission.

How Does It Help?: You can replace the installed pulley with a larger one, by using a larger pulley you can increase the speed.

Why It’s Worth It: A pulley swap is an affordable and straightforward upgrade that can make your lawn mowing tasks quicker and more enjoyable.

So, if you’re looking to supercharge your hydrostatic mower and mow your lawn faster, give a pulley swap a try!

Additional Considerations:

When modifying your lawnmower, it is important to follow all safety precautions. Be sure to wear gloves and eye protection, and disconnect the spark plug before working on your mower.

It is also important to note that modifying your lawnmower may void the warranty. If you are concerned about this, be sure to consult your owner’s manual or contact the manufacturer.

Finally, it is important to test your mower thoroughly after making any modifications. Make sure that it operates safely and as expected before using it to mow your lawn.

In this blog, I explained the smaller changes which resultantly increase the speed of your lawnmower. Although many people completely overhaul and modify the engine by replacing the pulley with a bigger one these are the modifications you need an expert technician.
