My Kubota diesel in the 928 Grasshopper I'm running is about to explode. It's had all sorts of cooling problems, but I got an oil analysis back today, and it's ingesting extreme amounts of antifreeze and has really high wear rates. It's only a matter of time before it self-destructs. Has anybody replaced a small Kubota diesel? What should I plan on price wise? I'm figuring that it's going to be in $4000 range by the time it's installed.
