I am a residential user with a 20 year old 36" Scag walk-behind, belt-drive, clutch mower. Its first 5 years were spent in commercial duty and now 15 years on my 1.5 acre yard. I love the machine and thought it would be a lifetime mower but it seems that I have lived too long. The Kawasaki FB460V engine is on its last legs and I wish to re-power. Since the FB460 is discontinued I have looked at the Kohler CV15T-41582 engine and the latest Kawasaki engine. While I like Kawasaki the Kohler is much more reasonably priced considering this is a residential machine. Question - Are there any suggestions for these or other engines that I may consider? I want to stick with recoil start machines. Thanks for any advice.
