I wouldn't recommend having one bot do plantign and shoveling. As you noticed it bugs out (a lot) and its super ineffiecent. You lose a lot of through put doing it that way. I recommend having one bot chopping trees, one bot shoveling holes, one bot picking up acorns and putting them in seedling tray, one bot taking seedlings out of tray ind putting into hole, one bot to pick up logs and store them, and one bot to auto recharge the others. Thats a fairly effeicent farm to get going then you can add bots where needed to increase production.
