Yea, Jon they got torque, I try to chill in turns unless grass is dry as a bone, plus with all this speed we can make-up any slowing down to be careful on the next strait. I tried the ZD-21 first the area Kubota rep hinted for me to get the ZD-18 which they had to order, said with the 6" smaller deck and smaller tires(more torque/spins faster than your tires if they were on the ZD-18) that I would notice no difference. And I think he was pretty much right(I saved money too, if I had the extra $ I would have got the ZD-21 just to feel I got the most power I could) Thanks for posting, ZD-18/21 just are so far now ahead of the ZTR pack WOW !
