How do i know when to stop filling the hydraulic fluid on a Massey Ferguson gc2300?

To know when to stop filling the hydraulic fluid on a Massey Ferguson GC2300, check the hydraulic fluid level using the dipstick located on the hydraulic reservoir. The fluid should be at the full mark when the tractor is on a level surface. Avoid overfilling, as this can cause foaming and reduce hydraulic efficiency. If the level is near the full mark, stop adding fluid to prevent overflow.
