Looking to add some 472's to fleet this year and was trying to decide between the 31hp kawasaki or the 25hp Kubota. The Kaw costs $11,749, the Kubota is $15,399. If I buy a couple I can get the kawasaki's for about $10,400 or I can pick up a 25hr used demo diesel 472 for $12,000. Is the extra initial investment worth it? Will there be a noticeable difference in power between the 2? Any insight would be greatly appreciated. Thanks.
