i have a older sears track snow blower worked great last year pulled out this week and it is stuck in reverse need help
Pull the cover plate on the lower rear of the blower (usually have to remove 6-8 screws), it should let you get to the internals on the back of the machine, around the axle(s). Most of these are friction drive, with a rubber wheel on a steel plate, pretty simple operation. You should be able to figure out any hangups/issues once you have that cover plate off.
There are a couple snowblower forums on the web where you might get more specific help (opeonthenet, abbysguide, etc.). Be sure to have your model number handy when posting for help.
Bout 5 years ago, whilst riding around on "trash/garbage night". i espied a Craftsman tracked snow thrower reposing along side the pile! So, i enquired at the house. They said to take it, and helped me load it!
So, being that i am an inveterate trash heap follower, i took it home.
With some TLC, i got it to run well. Couldn't find anything wrong with it, except for a bad case of neglect. I then sold it to a friend who has a long driveway, and is happy with it. Ya never know how the fickle finger of fate will knock on yer door.
