Need some info from you. Check the fluid level? How long has it been since the hydraulic filter and fluid have been changed? Are you using a good quality 821XL fluid? Have you cleaned the hydraulic filter to the right of seat and replaced the hydraulic fluid filter at the front of the tractor? All of these can cause the issue that you are having plus air in the system. Also check the hose coupler for the suction line going to the pump, it’s located near the bell housing on the right side of the tractor as you set in the seat. It has 2 clamps and they must be tight and the coupler hose needs to be in good condition so it can’t suck air into the system. Also keep the traction booster lever pulled to the rear, inside lever beside the 3 pt lifting lever.
