Any thing to do, is fun on a garden tractor or any tractor. Put them to use and see what they will do ! But be safe about it. !! Had a broken branch last week I was going to cut up. MF 12 would not pull it out, so got the ferguson tractor out, even it took three tries. But got the wood.
Poplar wood, not much good for any thing. Kindling , maybe??
Poplar works pretty ok for firewood, I wanted to try logging for selling the wood to campers/tourist for bonfires
