Nice pic's ! THanks for shareing !
Tell us more about the trailer the excavator is setting on . . . . .  how do you connect it to a truck / tractor?
What brand log handling machinery is that ?
You've posted in the past, your snowblower . . ..  there are older ones made like that here, and they can't hardly give them away. Are pull types more likely then back up push types ? Most snowblowers are backup/push types here.
