Hey Stroth-
I too just purchased a Bolens (used). It is a yellow color as well. It is a solid steel machine. The welding on this machine is amazing...there are no spot welds at all. It starts on the first try and has electric start (although there is no need to use it). My model # is Bolens 625. I just ordered the users manual from e-bay. It was $4 online. Take a look on e-bay and you might be able to find the manual as well.
