This is an AR attacher constructed from a JBS manure spreader. The shop offers two choices. The manure box is for one, while the silage box is for the other. The alternative option is for a silage box, which adds box sides and eliminates the beeters. Similar to the manure box, the silage box must be dumped by opening the back gate.
Additionally, the silage box's main body and box extensions may be colored differently.
This in-game vovlo truck from Giants complements the spreader well.
