I am considering purchasing a new Tiger Cub for cutting grass in Louisiana. I would be mowing 4 acres of grass every week or so (2 acres at my house and 2 at my Mama's house). The current price is $6,800 for a new Tiger Cub with 48 inch deck and 19 HP Kawasaki engine. Is this enough power for this mower? I asked and the price jumps about 1 thousand to bump up to the 24 HP Honda. By the way, is this mower the right "fit" for my cutting needs?
