If its similar to my 2t grain dump then you would need a pto shaft running to a hyd.pump which feeds a hyd cyl.
Then there would be the hinge which goes between the frame and the box.
You need to check to see if the box has a pivot point where the box is attached at the rear but can pivot from as it goes up.
Then of course there's the control lever in the cab which attaches to a rod which controls the hyd. pump.
Mine has a cable from the cab which is used to shift the PTO in and out,thats also needed.
That would be about it which is probably to darn much money to buy new so I'd be looking in the junk yard and hopefully if you found one all the stuff would be there.
