I'd use this with a set of forks. Weighs about 3800 lbs. Setup with wide tracks, it barely leaves a mark in grass provided you don't take any sharp turns. Has an 850Lb R.O.C. and would make short work of the job. Half day rental wouldn't cost much more than the tools you're looking at buying and would save you a LOT of grief. Plus if you rent a dump trailer to haul it in, you can load the asphalt into the dump trailer and dispose of it.
