Can anyone help me out with this tractor. It has an 18hp motor in it and runs like a top.The deck lost a spindel and I need to find a new one. The deck says model number 502 253622. Is this thing worth saving? I have the plow for it and would like to fix the deck. I am a total noob at this tractor thing. All I know is this tractor is ten times the tractor my Noma is. Would also like to put some ag tires on it.
