hi everyone i am new to this site. great site. i hope someone can help me with this question i am currently using an exmark 44" lazer hp. i have had it since 2004 . i think it is time to upgrade to a 52" rider and was wondering if a toro 52" z400 was commercial enough with a 21 hp kawi for me to use for roughly 100 accounts. the reason why im targeting this machine is the shop by me is selling it for $6300. i think this is a great deal. i would be using the vac system with this machine about half of the time. is this machine more for a home owner with a big yard or is it really for commercial use? thanks.
