Where do you put hydraulic oil in a Massey Ferguson 255?

To add hydraulic oil to a Massey Ferguson 255, locate the hydraulic oil reservoir, typically found on the left side of the tractor's rear. Remove the fill cap and use a funnel to pour in the appropriate hydraulic oil, ensuring you check the oil level with the dipstick to avoid overfilling. It's essential to use the recommended oil type specified in the owner's manual for optimal performance. Always check for any leaks or signs of contamination after adding oil.
