I have some terrain where the hills could be problematic at the point where the hill intersects with flat versus other off-camber hills. I am trying to determine if the 48" deck would cut better than the 54" deck (possibly scalping in this area.) I want to purchase a Hustler FasTrack 54 (or 48) Super Duty or the EverRide Hornet w/ similar deck size. The Hustler dealer would allow a try-before-you-buy, which is great. However, I do not want to waste his time trying a 54" only to take it back to get the 48". There are no fences or space restrictions. Any recommendations on deck size would be highly appreciated.
