I just bought a property for my business we have a solid 10 acres need to rip out around 650 trees (pistachio trees, five years old) I wrapped a tape measure around trunks and got a average of 20 inches. I need grade land, spread DG, compact DG make in ground docks for semi trucks trench waterlines around the edges of the whole property and prep a lot of land for cement in the future!!!

Now my questions are should i be looking into skids/tracks should I just use a completely different machine if so what would be
recommended and if I do go with a skid what size model should i get

Any advice would be appreciated

Also buying a machine and me doing the work is way cheaper than paying someone for all the work I Checked.
