I have a Mitsubishi 15 hp 2 cyl diesel, 4wd with R1's, and I specifically bought it to run a 48" bushhog for clearing with. It does exactly what I want. I do have a box blade with scarifier teeth and it works as it should. My only need for it is a custom made dump trailer so I can use it to shuttle fill from 20 acres away through trees and mud holes, I want to dump 4000 pounds, about two yards ish, but 48" wheel path, so I will have to build it. On my acres, my wife uses our Troy Built Lawn Tractor and cuts the 2.5 acres of grass WAY faster than I could with the Mits.
I also have my ASV RC-30 to dig and grade with. The rubber tracks are unstoppable. I get Gumbo here, and can walk through it with logs in the grapple. I have forks, tree boom, buckets and rootrake/grapple, so I never need an FEL. For that matter, I dont need the tractors box blade either....
I clear alot of land building disc golf courses. By alot I mean trail width, up to 60-80" wide but very selective clearing and grubbing, we want the trees. On my own land, I clear and clean up blow down and hurricane damaged trees, and my ASV can pick and carry logs bigger than the gaps between trees, to which I have gazillions. I am in an Oak Hammock.
I can pull my 6x12 dump trailer (the main transport trailer) into the woods, Load it with debris until I can't fit anymore, then haul it out and dump it with the ASV. It SUCKS to use it for dumping soils, so I don't do that much of it, And Frankly, a three or four yard pile of dirt is moved and graded in seconds, when I want dirt for a specific time sensitive project, I buy it by the dump truck load.
I recommend an ASV RC-30 with a grapple and bucket. They plow snow well too I understand. Then, any 25 hp Lawn tractor will do, maybe even pull a little trailer with it for smallies. If you have to dig, you rent an excavator. I've been on my land for 20 plus years, and rented an excavator twice. It makes no sense for me to own one. I have built 6 septic tanks and drain fields with my ASV RC-30, I can excavate, it just means a ramp into the rectangular pit is part of the deal. at 3000# 48 wide and 8' long, don't get hung up on small stature. The 33hp Catiperkins diesel has more than enough power, and speed- no need to go bigger and heavier.
I have two JD Gators, (20 year old) and have installed bed lifts, so for now, I get about a half a yard on each, and my wife or daughter, son or grands, can drive 20 acres and move the fill from where I am cutting it, to where I need it. (but I still want the micro dump trailer) usually just leveling a new area I have cleared off for a new shed or parking.....
