Can't decide between the two. Two dealers in my area only stock the 54" flavor. Pricing is only a few hundred more for the 54" over the 48". Dealer says he is willing to allow me to try the 54" before I buy. This is very nice of him, but I don't want to waste his time if I decide on the 48" instead. I am a homeowner buying entry level commercial. I have hills that meet at a low point and am worried that the 54" deck would be too large. Storage space is not an issue. I have been told by others that the 48" may cut better. Any truth to this? Would the smaller 48" deck directional change on slopes be more agile than a bigger deck? Also, I have been told to go with seperate pump & wheel motor (EverRide dealer trying to sell me a 48" Hornet over the FasTrack SD) versus the ZT2800s. I see more entry level commercial going with these ZT2800s. Would a homeowner like me ever even notice a difference? Any help or info you can provide would be highly appreciated.
