[QUOTE="brdgbldr, post: 125119, member: 7474"] The symptoms you have sound very similar to what normally happens when the auxiliary valve is locked open. When this valve is locked open it causes low pressure and makes it almost impossible to lift, tilt and drive. I’ve accidentally locked mine open while plowing snow and got very similar symptoms. Since the machine will work fully for 10 seconds I would lean away from the pump being bad for now. (Let’s hope it is not the pump) I’m thinking it is probably a valve. Check your control valve and see if any of the valves have not returned to neutral or are loose. Also make sure all of your linkages are tight and in good condition. You could have a bad relief valve that is staying open in the control valve. All it takes is a worn out or broken spring anywhere in the control valve and you can get a valve that opens by itself.
