Forks have holds near end to put pins through, to keep it secured to forks. The pipe portion of the ladder inserts into the frame of the steps and pins hold in place. Steps are much nicer (for an old man) than a ladder, especially when high up. When total height is not needed, can be used lower with only the steps down, or steps will fold up flat with forks, or fold over and lay on floor of man lift for storage. We like for the steps/ladder to be facing the tractor for ease of navigation in the woods. If the lift will go, the ladder will go. Just drive straight into work zone.
Yes, the forks are homemade, about 48 years ago. They have been adapted to fit on rear and front of 3 tractors. Recently used them on the rear of our larger tractor to move 4 ea 12'x12'x4" concrete slabs, about 1/4 mile.
