A complete overhaul of my Normand snowblower 

Fixing a 2006 Normand N86 280 snowblower
When we changed our tractor, we had a Heck of a deal (I thought) on one of their snowblowers they had.
Started as a little fix to a complete rebuilt... I did not expect this, but it's done.
I'd say probably you won't need to get to this point with just an Econor grade and it will do exactly the same job because it was only used on the farm. (Have seen a lot less driveways than a commercial one)
Link for the gearbox repair that I've used;
• Schulte Gearbox Teardo...
If you got problems with your snowblower, this video will probably help you out to figure it out!
Good luck!
