I have a Cub Cadet Z-Force 50" 23hp Koehler. It's a resi unit...I understand that. I purchased it when I only had six or seven weekly accounts, and it works great for that purpose, but now that I've worked myself into about 14 steady weekly accounts, and a few random one-timers that go on vacation and such. It has 260 hours on it, but runs like a champ. It gets serviced regularly at my dealer. I'm just wanting to sell this to purchase a used walk behind and possibly have some spare cash to buy gas cards for the winter. That's all I really spend money on in the winter as I'm still a student. Any help would be appreciated guys (and women!). THANKS!
