Filling tractor tyres with water can provide additional weight and stability. It's usually done with about 75% water and 25% air in each tyre. It's essential to ask a professional or consult your tractor's manual if this process is appropriate for your model. Here is a simple step-by-step guide to do this:
Materials Needed:
1. Water source like a garden hose or water pump.
2. Large bucket or a barrel.
3. Liquid tubeless tire ballast or Tire Water Ballast Kit.
4. Water and antifreeze mixture (if you're in a very cold area)
Steps:
1. Park the tractor on a level ground.
2. Locate the valve stem on the tractor tire. It should be positioned at the top to prevent water from spewing out during the filling process.
3. Remove the valve core using a valve core removal tool. Now your tire should not have any air in it.
4. Connect a liquid tubeless tire fill kit to your tire's valve stem. These kits usually come with all hoses and nozzles required to inject liquid into a tire and they are mostly designed to connect to a standard garden hose.
5. Turn on the water source. If using a pump, make sure it's pumping water into the tire.
6. Fill the tire until the water reaches the valve stem. Remember, you still need to leave room for air.
7. Turn off the water source.
8. After filling with water, pressurize the tyre with air. Your owner's manual should have the correct PSI for your tyres. Be sure to follow these guidelines to prevent over-inflation.
9. Replace the valve core and tighten.
10. Repeat these steps for each tire you wish to fill.
Note: Antifreeze can be added to the water to prevent it from freezing in cold weather. Always check your tire pressure after filling them for several hours or the next day to ensure a good seal. Always remember safety first. If you're unsure, it's always best to have a professional do it for you.

Before attempting this operation. be aware of potential issues that may arise. The added weight of the tractor can put pressure on the axle or bearings. while cold temperatures can cause tires to explode if water freezes inside them. It is recommended to consult your tractor or tire manufacturer prior to proceeding with this task.
