I love this mod but I have a few things to point out:
(1) The drums don't turn unless the planter is down and moving. There were a few hydraulic drive ones built but they are most commonly chain driven.
(2) The hitch does not have or need a jack.
(3) The wing wheels should be raised when it is in transport and hooked to a tractor, when unhooked they should be down.
One other cool thing would be if you could fold the markers into their "field mode".
Anyways like I said love the mod Im not complaining I just happen to run 3 cyclos on my farm irl.
