30 horse 4x4, 2800 rpm, differential lock engaged. it climbed up the hill out of the woods into the orchard and came all the way home. maybe this post should be on the why fwd thread. without the chains it wouldnt even have gone out let alone come home. but the 4x4 let the little tractor act much bigger. check out the big white oak. standing dead at like 20 inch dbh. correct notch and backcut but it would not fall. needed to whinch it over. god i love this tractor/loader.
