* Power steering hoses
* Power steering rack
* Tie rods
* Steering wheel
* Fluid (hydraulic oil or power steering fluid)
* Set of wrenches

2. Prepare the tractor. Park the tractor on a level surface and disconnect the battery. Remove the front wheels, fenders, and hood to gain access to the steering components.
3. Remove the old manual steering system. This includes disconnecting the steering linkage from the steering box, removing the steering box, and removing the tie rods. Be sure to cap off any open lines or hoses to prevent fluid from leaking out.
4. Install the power steering pump. Mount the power steering pump in the desired location and connect the hoses. Be sure to seal all connections to prevent leaks.
5. Install the power steering reservoir. Mount the power steering reservoir in a location that allows easy access for fluid maintenance. Connect the reservoir to the pump using the provided hoses.
6. Install the power steering rack. Mount the power steering rack in the same location as the old steering box. Connect the tie rods to the power steering rack and secure them with tie rod ends.
7. Install the steering wheel. Attach the steering wheel to the steering shaft and secure it with the provided bolt and nut.
8. Fill the power steering system with fluid. Use the recommended fluid specified in the tractor's operator's manual. Check the fluid level and top off if necessary.
9. Reconnect the battery and test the power steering system. Start the tractor and check for leaks. Turn the steering wheel to check for proper operation of the power steering system.
Note: It's important to follow the instructions provided in the tractor's operator's manual for specific details regarding the installation and operation of the power steering system. If you're unsure about any of the steps involved in this process, consult with a qualified mechanic for assistance.
