I agree with Chris. I bought the CK 25HST last year, mid summer. I got the fel and the First Choice 60" finish mower, and First Choice 56" tiller. My grass never gets high and the 60" mower has no problems at all. I like the 60" because it will clear what ever the tires clear going in a straight line, which is nice for mowing up close to fences! The 72" will be fine if the blades are sharp and the grass is not too high or tough, and gives that extra width in cut. I looked at a CK30 shuttle shift yesterday while buying filters. If I could go back, thats what I would buy. The HST is only good in low range for any kind of work other than mowing grass( for me). The shuttle shift would be more powerful being a gear drive. You also loose the use of the rear brakes( no spinning around on a dime) on the HST. I might go back and talk a swap! I would also get the CK30 for the extra HP. The HST is very useful in changing directions, but not so much so if you are going forward most of the time.
