I like the idea of the mini skids and from what Ive read everyone seems to like them alot. How capable are these (tracked model, dingo 420/425 or DW 500) when it comes to digging and grading with a bucket with or without teeth. Would removing an asphalt driveway and digging 8" down be really overworking the machine. What about removing 5 yards of soil off a high spot in a yard without first cultivating. Although jobs like these might be better suited for a bigger machine can they be done without really overworking a mini and/or wasting too much time?
