Tractor Repair: Farm Trac 545 tractor, farm trac, suction screen

Question
I have a front end loader on tractor. It operates very slow up and down and slow at dumping .Is it air in system or something else thanks frank

Answer
First you need to change the hydraulic filters. When it is running and you are trying to work the functions check the oil and see if it is foaming. That would mean that it is sucking air or has a restriction such as suction screen plugged. You probably have a pump going out or your main relief valve is stuck.
