You would ask me that. This spring it went home with the Son in-law so it's in Minnesota. It was yellow and originally 3.5 hp which was pretty pathetic. Just did a search and can't find a picture of one like it. It was probably 30 years old. Sent him a text so hopefully I'll get the name in the next couple of days.Cvans, what make and model of chipper did you put the HF one on?
