I bought 3 sets of Gator blades from J Thomas late last year, I got them checked them out had a sticker on them for M60 Tank. I thought Ok mowing seasons over will use them next year. I go to install them this year and they are way too close to the deck, I call J Thomas up it's past our return time so we can't help you. You can take them to somewhere near you and see if the will trade you blades, I could not believe what she said. Yea right sure they will trade me, after getting no where with them I called Oregon and talked to a nice fellow named Dennis. He told me that Cub made some changes to the deck over the years and that there are two different decks, mine being the smaller deck the longer blades will not fit. Told him my trouble with J Thomas, he was very understanding. He sent me 3 new sets of blades no charge and told me to keep the old. Well to make a long story short I'm done with J Thomas! Oregon is a top notch company, they will be seeing me again! Thanks Dennis!
