Re: John Deere 9 Series Tracked Tractor with Planetary Steering
No magic! The forward (insert) part of the hitch telescopes into the rear part of the center frame hitch, just like on the real DB planters.
I use SolidWorks for all my CAD work. |

Re: John Deere 9 Series Tracked Tractor with Planetary Steering
I thought it was probably something like that. If I'm reading it right, the center section will telescope back when the wings fold, and telescope forward when the wings open. I know this is just a model, and that it won't be under the stresses of the real machine. But once they're unfolded is there a mechanical stop to keep the wings from trying to go beyond their open position? A hard stop so that the center section can't move any farther forward maybe? I would think that the wings will want to fold back if there is any kind of drag on them once they are open.

There are stops on the real planter that keep the wings from over-extending. I'll have some adjustable stops on mine to make sure everything lines up & has some room for adjustment. |
