Just to let you all know I purchased the RSD 54". This is my first hustler and I am not a professional. I have owned an exmark and a husky walk behind both were commercial and worked great, but I have a new much bigger yard and I convinced the wife I needed a zturn. I ordered the 48" and as luck would have it the dealer also ordered the 54" as well. I was at the dealer when they took them out of the crates and we were both surprised to see the differences between the two. I am sorry I don稚 have the exact specs but this is what I remember. The 48 still has a lot of the same residential elements that did not impress me much. The 54 has the same front casters as their commercial mowers, and much bigger rear tires which I wanted for my mowing conditions. They both have the same wielded decks, but what made my decision was the price difference. The 54 was $100 more. Even the owner of the dealership told me not to buy the 48? Like I said I知 sorry for not having the exact differences, but if can go and see them sitting side by side, you would not buy the 48 model. Hope this sheds some light on the new mower.
So how are you liking the mower? I am in the market for my first Z-turn with around 1.4 acres of clear land to mow. I am down to the Raptor SD 54inch at $3,999.00 or the Kubota ZG124E... The Kubota is only a 48inch deck and is $500.00 more with I believe a Briggs and Straton engine and $1000.00 more with a Kohler engine and front lights.... I'd be at a whipping $1500.00 more to get a 54inch deck.... This is why I'm really leaning towards the Raptor SD.... Appearance I believe Kubota wins but I'm obviously not going to buy based only on appearance factors. Someone please chime in.
