2 acres to mow, have a Swisher now but you have to push the handles the entire time, almost as hard as pushing a push mower. The others I have used, the handles stay where you put them. So that is #1. #2 is reliability and ease of repairs for the DIY. Replacing spindle bearings on the Swisher is a job I don't want to do ever again. Have around 4-5K to spend and would like to avoid units with troublesome EFI. Kawasaki engine vs B&S? Let me know what to avoid or what has worked for you. Thanks.
