I have a 3520 with a 300 CX loader. The Steel hydraulic line which controls the up and down movement to the bucket burst. I replaced the line and refilled the hydraulic oil. Now the bucket will not stay up. Any help would be appreciated. Thanks.

More info is needed please?
Was the line damaged or rusty where is burst?
What where you doing when it happened?
How long does it take to drop?
Is the the lift/lower or the dump/curl line that burst?
If the line was over-pressurized from improper use, then the cylinder seal(s) may be damaged as well.

About a year ago had removed the bucket and put hay fork on 400 X loader frame. lower forkes and lifted front end and steel line blew sparyed oil everywhere. Replaced hose and then the tilt portion would slowly droop so changed seal in cylinders .still a continued drooping tended to almost lose hay bales so second time did the cyl. seals found no problems then looking at a Quick disconnect plug found part of seal o ring in opening by the ball. releasing the pressure. pushed in ball needle nose pliers pulled the portino of seal out all is good again.
