I am looking into buying a mower with the liquid cooled option. I know in terms of resale, it might be better than air cooled but really....what are the differences? The largest property I currently mow sees me on the machine for all of 35 minutes tops and it's not everyday (maybe two days a week tops). The price difference is substantial in terms of out the door pricing and now I am just trying to justify the expense. Until now, I have never owned a liquid cooled engine nor have I needed one (atleast I dont think so). In a nutshell....is it worth the extra $1800 smackers?
