The easiest way to check the hydraulic fluid level on a Massey Ferguson tractor is to look at the sight gauge next to the hydraulic fluid filter. If your tractor does not have a sight gauge, you can check the fluid level with a dipstick. If the fluid level is low, you will need to add hydraulic fluid until it reaches the “full” level. It is important to use the correct type of hydraulic fluid in the tractor to ensure the system functions properly.
