Zero grazing loading wagon

[Devonfarmer]

I dont know whether anyone will understand, however if someone is able to make a modded loading wagon which is used for the modern zero grazing way of farming it would be highly appreciated. As I'm not a modder I don't have any idea as to how much work it would take to make it. It shouldn't need any outside scripts as it's just a mower mounted on the front of a loading wagon which then picks the grass up. Any info on this would be greatly appreciated thanks in advance.
