Dapper, I went to the F from the 326 mainly for the 4wd. When i mowed ditches with the zd if it was a least bit wet I just as well have the rtv ready to pull me out. Then reading about the "f" series I thought I would always want one. Started mowing 4 acres each week for inlaws, thought this would be the time to get one. I was hesitant about the 72 inch deck, but again I thought why not. My biggest decision was rd or side discharge, but the side discharge would fit on the trailer I had, so went with that. Now with the mulching kit on I am real pleased, no grass clipping all over me when done. Don't know how it will be if the grass gets out of control, but I am very happy with the setup at this time. Added mirrors on the F this weekend to keep me from getting run over on the country road ditches I mow for the inlaws. On the front wheels I replaced mine with solid wheels when I purchased it from the dealer, also I just placed a pin through the top hole on the wheel, so no cat 8 bolts for me now.
