Then, the top 40t gear would have to be rotated by half a tooth to mesh with the crown gear. Finally, the two side "blades" of the implement will have to be rotated to mesh with the center one (which should end up being correctly oriented once the above problem is fixed).

Also, I spotted some extraneous 1x4 beams attached to the rear axles of the tractor, duplicating ones found in the lever-1 submodel. And, is there any particular reason to have the model's origin (0,0,0) so far away?

Finally, the steering column isn't fitting inside the 1x2 beams that hold it—this is always a tricky problem with these sets. And something's wrong up front, where one of the 8t gears is colliding with the 1x2 brick holding the axle. Looks like both gears just need to be slid backward.

Sorry to pick apart so much! Technic models are definitely challenging because of stuff like this, but that's where the fun (?) is with them.  Smile  And I've certainly had invaluable help from other members of this forum in solving some of these challenges. You're welcome to have a look at my version of the tractor model (attached) if it's useful at all.

As for when models get added, I think it's a weekly process, though in my experience it seems to be quicker than that, once everything's compliant of course. On that note, the OMR spec does have guidance about file structure for sets with alternate builds—would that apply to the different attachments in a set like this? If so, I guess there should be a separate MPD file for each version, named according to which implement is attached—but good luck figuring out which real-world implements each one is supposed to represent!  Wink
Hello NW Perry,
Thanks a lot for your comments. I am surprised to see 2 remarks I can't place after almost using MLcad for 10 years.
1. the whole implement is about 5 LDU off-center in the X direction; I don't know what this means? I am not aware that you can place a model somewhere specific.
2. [color=#333333][size=small][font=Tahoma, Verdana, Arial, sans-serif]model's origin (0,0,0) so far away; probably same as point 1. I will try to find out in MLcad where you can adjust these settings.
3. Regarding the gears, I never do the meshing of the gears, was not aware that is necessary.
4. I will read the guidance, I only used the MPDcenter check tool.
To summarize I have some home work to do!!

Thanks again, much appreciated.
