Ok long story short. Right side of zero turn rider was getting weak and would stop pulling after 30-45 mins. So I started looking around for the model # so I could at least soo how much the part,(s) I need would be. I can not find a model # or anything on this mower. There is a sticker under the seat that says 01 oct 12. So I'm guessing it was made in 2001 october. I only got the mower last year from a co-worker, and it only has 500 hrs on it. There aren't any stickers under or on the floor board. I ever called cub cadet, and talked to a guy there and gave him the #'s that were under the seat. There is a sticket under seat that says S# ..... V#..... He said he thought it was a tank but he couldn't be sure. Anyway, it has a 23HP Kawasaki engine, zero turn rider. The seat does say cub cadet commercial. What I'm wanting to know is if I post some pics could someone help me out? I jus tneed to know th emodel number or the pump brand maybe. thanks for the help
