Picked this up tonight for $200 four minutes from my house. I collect and restore old garden tractors, so this thing is new to me. First question, what are the weak points of the machine? Second, how stout are the transmissions? Would is be possible to upgrade to 12" rims? Can they handle a plow? Thanks everyone! Looking foward to learning about this thing! 00R0R_iy5bFsgsnuu_600x450.jpg
