I've had a trio of 4WD Kubotae and a Ford. All have that what looks like way too much positive camber. Here's a pic taken recently that kinda shows the LF tire. I grooved them about 3 years ago. The tread is worn on the outside to the point the grooves are nearly gone, while the inboard side shows almost no wear. If it was easy I'd remount them on opposite sides. Most likely I'll just recut the grooves.
Really clean looking tractor there gumshu. That loader probably wouldn't put up too much of a fuss if you offered it a little grease
