Hey, I just got the 20\52 with the Kohler and I love this thing. Its my first ztr and what a difference it makes. I have alot of turns and odd shapes to my yard and its now even fun to mow instead of a chore. I got mine for 4611 with tax and everything deliverd to my door and he even filled both tanks to the top. I can't wait for the grass to grow again. I may buy the spring seat later because my yard is rather bumpy. Great mower...two thumbs up!!
