1. Start by making sure that all of the fluid level are checked and topped off.
2. Disconnect the return line from the master cylinder and place a bucket underneath the line to collect any fluid that may come out of it.
3. Open the bleed screw on the master cylinder and have someone pump the clutch a few times. This should cause some fluid to come out of the return line.
4. Once you’ve seen the fluid coming out of the return line, close the bleed screw and reconnect the return line.
5. Open the bleed screws on the clutch and brakes in a star pattern. This will ensure that the air is bleeding out of all components at the same rate.
6. Have someone continue to pump the clutch while you open and close the bleed screws one at a time. This will cause air and fluid to come out of the lines.
7. Once all of the fluid is out of the return line and the bleed screws, close the bleed screws and reconnect the return line to the master cylinder.
8. Refill the fluid reservoir with the correct type of brake fluid, ensuring that it is filled to the proper level.
9. Test the system by taking the tractor for a test drive, listening for any air bubbles coming from the lines. If you hear any, you’ll need to open the bleed screws up again.
10. Once everything is working correctly and the brakes are functioning as expected, close up all of the bleed screws and master cylinder.
