I have two pretty steep hillsides with a pond at the bottom of them that I mow with a Zg327 zero turn Kubotamower. My wife and kids want me to get something safer and maybe they are right so I was wondering about a ventrac 4500 mower .from what I have read most of you really like them.do you really think they are worth the money? I would really appreciate your thoughts on them. Thank you.
