New tractor owner of MX5400. Just got A box blade so this is the first time I’ve really used the three point hitch. I noticed that when raising the box blade, it doesn’t seem to move until I get up about halfway on the control. So if the numbers go from 1 to 8, it doesn’t seem that the blade even budges is until about number four. Is there something wrong with my three point hitch or is there an adjustment that I don’t know about to make it start lifting at lower numbers?
