Most companies offer a 32. 36 and 48" WB in this class but they mostly offer them with the same or very similar engines for what seems to be a large difference in deck size. Can the 48" models really carry that deck through thicker grass or will they have a problem when compared to the 36" models? also the 32" models seem to always have a downgrade on the deck using an older design or smaller tires, is that usually the case also? I would like to get one that is capable of going through some thick grass but not use smaller tires and get inferior finish cut. Advice?
