Anyone using JD Quik Trac mowers? Are they any good or trash? From the movies on their website they seem to cut pretty good even on tall stuff. I am going after a bunch of smaller property's next year and need one on a big 20 acre condo's contract and thought why not get a stander instead of another walk-behind. The model I am looking at getting is the 647 48in. Also anyone using the 757 with the new mulch on demand deck? How are these machines doing? Also how are these with the JD bag kit on them? Do they make a clean pass? Don't get me wrong Dixie Fans I still am a die heart dixie fan and will always be but employees tear up to much turf with theses cause they move to quick. I still am buying another Dixie in the spring no matter what cause I took on a big contract but I need a stander and maybe a 757 if I get enough work to run this machine. And also the green fleet is tempting. How much of a discount do you get if you get the green fleet?
