1. Locate the hydraulic reservoir on the tractor. It is usually a gray or black plastic tank located near the rear of the tractor, behind the seat.
2. Remove the filler cap from the hydraulic reservoir.
3. Use a funnel to add new hydraulic fluid to the reservoir. The type and amount of fluid required will vary depending on the model of your tractor, so refer to your owner's manual for specific instructions.
4. Replace the filler cap and check the fluid level. The fluid level should be between the "Full" and "Add" marks on the dipstick.
5. Start the tractor and let it run for a few minutes to circulate the new fluid.
6. Check the hydraulic fluid level again and adjust as needed.
It is important to keep the hydraulic fluid level at the proper level to ensure that the hydraulic system operates properly.
