John Deere 9 Series Tracked Tractor with Planetary Steering

[cooker2003]

Most of the hydraulic components are from Magom HRC in Spain. It's nice that they provide the CAD models to help with mock-up.

Made some more progress on the disk & getting close to wrapping it up. Functionally, it works really well. I'd like to swap tires with actual rubber ones (versus 3D printed) but haven't pulled the trigger yet.



I've got a couple videos demonstrating the hydraulics - which are quite impressive (strong) for being 10mm diameter. I started to machine my own cylinders on my lathe & quickly realized that is some tedious work. I found the components were available separately from Magom & went that route, which allowed me some more freedom on determining cylinder lengths, etc before brazing them together.

Going to be switching gears to a planter soon! Got started with a preliminary mock. It will be mainly steel with the row units likely being 3D printed. Planter will be a lot of work, so we'll see how far I get.
