I wrote a post about my Pro Z-160 last summer. It is a Cub Cadet Pro level with all wheel steering and steering wheel or lap bars as options. I went from a Scag Wildcat with 61" deck with blower/bagger I bought used with 200 hours. I sold it last year to my excavator for $4K. with probably 400 hours.
IF you have any sloped ground the CC will go up/down, around any other conventional ZT.
I know lots of people think you have to buy the real expensive high end machines, BUT I'm here to say it makes NO difference if you have sloped or hilly land, etc. They will NOT perform well in those conditions. Yes, some have lowered COG and displaced weight more evenly, but when one decides to take off down a slope there is NO stopping them. The CC Pro series with front wheel steering is completely different. I couldn't believe the difference when I drove it. I got a carbed 23.5 HP Kawa gas engine, and it is quiet and fast and cuts incredibly tall grass without strain. No blower or bagger needed, I just mow and done.
It's very solidly built with two serviceable transaxles, Hydro-gear with a Hydro filter on each one. There is a EFI Kawa too but more money for it. I got mine as a off floor demo for $6K vs. $7K + new retail. I am very happy with it. Check it out and find my other thread about it- there's more details on the mower.
