I have a 2000 craftsman gt 6spd 50" deck. This is the year before gt3000 They look the same except for side muffler and grille on top of hood 22hp kohler v. 23 hp kohler. The deck is the same as the one on last years grey gt5000 w/b&s 22hp 12 gauge deck. Was looking on the sears website at the gt5000 10 gauge 50" deck w/4 gage wheels. Ordered the 4 mounting brackets and related hardware,it all bolts right up to nonused existing holes. Only needed 2 wheels as the old are the same. Also added gators and nose roller, and removed deflector shield made a big difference. If anyone is interested the model # for the gt5000 is917.276030, I think it may also have greasable mandrels, will probably try these before next season. I know everyone is thinking about snow not grass but what better time to play with deck? Right now the blower is mounted and using four 55lb wheel weights(2 on each wheel) along with sand canister and tire chains. Will put hardtop cab w/electric wiper on soon, looked like frosty during last storm!
