I would've bought a skidder if it came with a FEL, PTO, three point lift and was under 25k. So being the add-on specialist that I is, for the possible damage that I was able to for see, from the experiences that I accumulated over the last 50 years of cutting and hauling wood in about a dozen + different ways.The tie rods on the Kubota tractors I have seen are ahead of the front axle but well above the front axle. My thinking is if you want a skidder then buy a skidder. If you use a tractor in the woods then don't use it like a skidder and run it thru the slash and over stumps. Keep it on a clear road and keep the roads clear. Or try to be careful and add protection. Even then expect damage. There are to many parts that can't be protected and just aren't rugged enough for forestry use. Tires for instance. Compare standard tractor tires with forestry tires. There is a reason they make forestry tires.
But stuff just happens even just working around the dooryard. That's life.
Just my 2 cents.

The first thing I added was skid plate in the first week, followed by a protective box around fuel filter that had a sign on it saying, HEY STICK HIT ME. In the first year of owning my tractor, I added a beefy roll cage with limb deflection screens at hands reach because I just dont get a thrill out of the constant aggravating job of trimming limbs on every woods trail, however I do acationaly trim some limbs on the main outgoing woods road, so now after 10 years I finally do have Kuuboota skidder that will turn around in the smallest places.
