I have a 2oo6 Kub L28oo. It seems to have lotsO traction plowing in the snow, even when it is deep. However using an angel plow when making the first plow after a heavy storm keep a line is tough. Also when re plowing the piled up snow on the berm in order to give the next new snow someplace to be moved to also is a tad difficult to keep a line on. I now lift the plow half way up the depth of the berm n just plow it twice, so more time n fuel/ware an tare.
So I also am considering adding chains to only the front, more so for steering vs additional traction. I keep my hoe on the back all winter/the time so the rear set of wheels seems to get plenty of traction due to all the weight. However, with only a 28hp motor that probably does not weigh that much, thus not keeping the front wheels from spinning in the snow n ice I suppose compared to the rear.
I also have AG tires on all 4 corners that still have lots of lug remining.
I like the one person's suggestion to put studs in the front tires. I may check into buying a set of both wheels n stud tires. Than just change them out in the fall n spring when the loader bucket mounted is remounted in order to lift the tires off the ground for easy change over (I remove the loader bucket for snow plow lifting and replace the bucket with a 4 foot + - wide by 6" square piece of box steel mounted on both the end of the loader arms and hydro ram ends thinking this will help keep the ends from twisting and being bent back if only one arm should take big hit sometime, see below foto).
