I have a Jonsered AWD walk mower (L4721) My understanding is it's a Husqvarna (but can't find one that looks similar) It has issues with the self-propel (slow and loud squeal noises) Trying to find out if it has two belts (one for front, one for rear) or just one large belt. These are no longer made... where can I get parts?
This is my first post here.

I found the machine and it appears to have one drive belt, (which is available).
