Sorry to say but the hydraulic system on these tractors are very complicated compared to other makes i would suggest you leave it with a fairly heavy weight on the linkage overnight the arms will be partly down or all the way down then start up and only lift the arms up but not all the way then see if they will go down when moving the lever down if not you will need to get a manual and follow the instructions on this fault.
