This truck has an interesting looking PTO powered cattle feeder.
“For sale here is a 1955 Willys farm truck. It has the 226ci Super Hurricane inline 6cyl. 3spd manual, and PTO. Motor turns. I haven’t messed with it much. It has slight rust but is in good shape for a 61yr old truck. Bed was converted to an action bed for feeding cattle (ran by PTO I believe). If you have any questions, just ask. Trades are possible for classics.”
