Where do you put hydraulic fluid in a Massey Ferguson 231 Tractor?

To fill the hydraulic fluid in a Massey Ferguson 231 Tractor, locate the hydraulic reservoir, which is typically found under the seat or near the rear of the tractor. Remove the fill cap and use the appropriate hydraulic fluid recommended in the owner's manual. After filling, check the fluid level with the dipstick to ensure it is within the proper range, and then replace the cap securely. Always consult the manual for specific instructions and fluid specifications.
