Nice build and set together but its very hard to get it
to accept branches. Nearly as shall force the wood
under the drum. It not be transferred by the belt.

Looks practical, but single axle ?
Giants made it wrong, you don`t use a single axle truck in the forrest, you would get stuck pretty fast..

I will give you credit for a nice mod though, but wish you would consider a dual axle if you are making a V2.
