Have you ever wondered if changing the tires of your lawn mower can increase its speed? Well, it is valid for hydrostatic lawnmowers. Hydrostatic lawnmowers usually come with smaller tires than required for a fast pace.

You can replace the smaller tires with the bigger ones. Bigger tires have some advantages over smaller ones. They have the appropriate circumference to cover the mower distance efficiently while using the same amount of engine power.

Hence, replacing smaller tires with slightly bigger ones is a smart way to make a hydrostatic lawn mower faster. However, you must note that your tires must not be too big to keep the deck in the appropriate position.

Bigger tires usually raise the mower deck. A raised mower deck is inefficient for cutting grass. It also affects the center of mass of the lawn mower, which can cause problems while mowing rough terrains. Keeping these aspects in mind, you can change the tires of your hydrostatic lawn mower.

2. Better Fuel
