I have a job that would consist of pushing over about 3/4 to 1 acre of trees(some sort of christmas trees) that are around 12 to 20 inches at the base. I will need to prep the ground for a lawn afterwards. My Loader contractor has both his machines down. I have tried too contract a few others but most are weeks behind. I may be faced with renting a machine and doing the work myself. Was thinking maybe a JD 555 loader or a 30k Excavator with a thumb. I have a skid steer too help move stuff. I will need them in piles for a tub grinder. Since I am renting I will need the machine that will get the trees up the fastest. Any Opinions. There is a large amount of work after the trees are removed for my equipment so without figuring out a way too get the trees out and in their budget I may loose the more profitable part.
