Clearing Fields with the Skid Steer

I spent roughly a day and a half of time with the skid steer on clearing some area of yaupon slightly downhill from the cabin.  

There is also evidence of the field being cleared in the past.  There are several piles of dirt and large rocks which were pushed together.  I focused on clearing the yaupon first but I'll need to address the piles as the yaupon will likely grow back and if I can't mow it then it can't be maintained.  

The goal is to create a two acre area downhill from the cabin which would add to the view and give us more area as the rest of the land is wooded.
