JD 8320

Very nice video, and nice work on that JD, Rob. I like the working 3 point hitch. Is it servo operated? If so, how much torque does a servo need for lifting something like that planter?

Could you show us more about the tractor? Hitch, Transmission, ....?

I will take some pics of the innards and post for ya. I used a Tamiya gearbox driving a wedico diff. Had to do a lot of shaving on both the diff and the tractor to get it to fit.

Nat, I used a Hitec 645MG....it is place under the seat. At 4.8v, it has 107in oz of torque. I don't know if i over kill it, but i also use a CC bec to draw more power directly to the servo. Now it doesn't kill the spd ctrl'r when lifting the planter.
