I am stuck on picking out a ZTR. I have been shopping around a lot and I am down to these mowers because of price/location/dealer. I have to stick with a 48" deck because of gates I could possibly do 52" but the 48" is safer. The Toro Z400 21/Kawa with the turbo deck $6700 John Deere Kohler z710a $6500 Kubota 22/KubotaZ222 $7000 I can get a Ferris IS1500 for around $6100 but I was told the other models were a leap ahead of that. Can anyone give any info on these mowers price and performance feedback would really be appreciated.
