I am in the process of buying a new mower but need some help on a few things. This mower will not be used often, mostly just at home. I want power to run a 60" snow thrower also. Is the Kubota 25hp liquid worth $900 more than the Kohler 27hp liquid? Or should I just settle for an air cooled Kohler 25hp for $1,700 less than the Kubota? Options: Kohler 25 hp air Kohler 27hp liquid + $800 Kubota 25hp liquid + $900 ($1700 total) Please advise on quality !
