J.D. E120 Snowblower attachment works very poorly

From personal experience, “DO NOT” use aftermarket belts on JD equipment or accessories. To the OP, please provide us with the tractor and blower model numbers from the ID tags. That way we will be able to see exactly which pieces you have and provide the correct part numbers and possibly manuals.

I've uploaded detail for both tractor and snowblower.

Snowblower belt is John Deere #M158130 and should be 149” long. Here is a manual for your blower. http://manuals.deere.com/omview/OMM177515_19/toc.html
