The owners manual says to not run the RTV at "full speed" for the first 50 hours. A Kubota rep was at the dealership when I picked up my RTV, and he told me to "just drive it". He did tell me to avoid constant speeds or engine RPM's for long periods of time for the first dozen hours or so. For example, don't drive it at wide open throttle for 10 miles down the road. Otherwise, just drive it like normal.
