I have a model 4089 JCP snow blower. How old is it and where can I find a usersmanual?

Hi,
If that JCP means JC Penney, then it probably from the 1980s and made by either Murray or Dynamark, though MTD is a possibility. Info off the frame of the machine and/or the engine could probably narrow that down. Frame numbers can often be foun inside the handle frame to preserve them from damage.
Peace,
Clarke

whiskey1, I see a manual for a model 4049, could that be yours?

I'm curious if this link will work.
