I'm debating between the Exmark Lazer ZHP 48" 21HP Kawasaki and the Scag Tiger Cub, 48" 19HP Kawasaki. I can get both for the exact same price. Both of these are probably overkill for what I need (residential use only), but I don't want to buy another mower again. Does anyone have any opinions or advice on which to buy since the price is the same. I want the best cutting machine that is also the most durable and will hold it's value (in case I ever need to sell). Any input is appreciated. Also, I can get the Husqvarna ZTH 42" 18HP Kawasaki for $1,000 cheaper. Any recommendations?
