I heat my house with wood heat 24/7 all winter and it's all wood I dropped and dragged out with my 2615hst. My tractor has taken a good beating in the 3 years I have been processing firewood with it. Side effects so far: Put a big stick right betwen the tire and rim last year, somehow it sealed back up and I haven't had to repair it and most of it has ground away. I put a bigger battery in it when I first bought it and apparently didn't tie it down well enough..while yanking a full tree after I dropped it, the battery hit the grill and broke the grill mounts and I now have bungees holding it in place. I was pushing over a stuck tree and had another tree break and come down on my hood which I hammered back out but you can still tell. Once when I pushed over a full tree (not for firewood), the root system came up under the tractor and pinched a gas line and it stalled out on me but caused no lasting effects. I had a stuck brake issue for awhile which the dealer thought was a transmission issue, but it was probably from limbs bending the brake arms in the back. I removed both plastic headlight lenses, they just kept breaking and actually the lights are brighter without them. I use to drop full trees that I had to round with my chainsaw (20" bar) and limb it and drag the whole thing at once. Now I have been cutting them in half using middle gear to prevent the yanking and tire spinning. This thing is a beast and I'm pretty sure a lesser tractor would have given up by now. I'm trying to be nicer to it. I have the Industrial tires that are filled. I think it's the perfect size for logging and moving firewood.
