I presently have a 50" ZTR but it is a high end home owner. I can't decide on a 48" or 54" commercial? I have 3 lawns as of right now that are 2 plus acres and 10 others I can use either on front lawns. But how many gates might fit a 48" but not a 54"? Also I have 1 acre of cutting at my oun house. Thanks in advance for your opinion. Not looking for opinions on brand just size.
