I'm thinking of buying this mower. I mow about 4-5 acres. I have what I call my golf range which is basically a 4 acre run out hay field that I mow. It is flat but sometimes it gets a little thick. The Briggs is $200 less and has more horse power. I have heard good things about the Kawasaki and mixed things on the Briggs. I'm worried a little about it being under powered at 24hp for a 61" deck. It seems like most 60" plus decks have a bigger engine. Any advice would be appreciated.
