Brian and others: I have been reading all the posts and doing a lot of research and will definately be purchasing an Exmark in the next week. I am mowing an acre weekly and want a "commercial grade" type machine that I can use for the next decade so I have foscused on the CT, HP and AS. I do want a collection system on the back and a deck no bigger than 52. I'm watching my $$ but quality is just as important. Questions: Is there much of a time advantage between 46"-52" on an acre? Would the 19KAW be enough? Do you have a specific setup you would suggest and what be the MSRP? Thanks. Great site!!
