I was looking at Little Miami tractor page and he has a couple of YMG2000D tractors for sale. I have a YMG and reallly like the tractor. The one's that Wayne has have a different tread than mine. The ones on mine are rice tires and the ones on the other tractors are a lug tread tire but look like they would do a lot less damage to the yard when it is wet. Can these tires be bought or are they some not sold in US. The 1st image (dirty one) is my tractor. 2nd one is Little Miami's tractor. Thanks for any input big dan
