I have a four wheel page tractor that I am trying to identify. It has a Kohler K161 engine s/n 407769 spec no. 28287E
A few people said it must have a 7 digit s/n, but it doesn't. This is what is stamped on a brass tag on the hood of the tractor. I really would like to know the year built. The frame and engine originally looked to be painted light green, and the hood, and fenders somewhere
near case red. Engine is front mounted and the steering goes right straight down through the hood. All help appreciated.
