I presently own a CK 20hst that I absolutely love,it does everything that I have asked it do and more,I have 1200' driveway that I grade with a 5' box blade and the hst has plenty of power even with a full load of gravel,
Previously I have owned both gear and hst and shuttle tractors,and for my purposes ( grading ,blowing snow,moving earth and gravel etc) the ck 20 is the perfect tractor.
As far as cutting grass with the industrial tires ,as long as I don't cut the day after a big rainfall they don't mark up the turf any worse then the turf tires on my riding mower.....
I looked at many of the same tractors as you when I was looking for my new tractor and for my money none of the other small tractors offered anywhere near the value......that said this is your money so take your time and try as many as you can before you buy ,good luck
Don't forget you have to show pictures after you buy
